Sonus Networks Broadens and Enhances Open Services Partner Alliance Program
Integrates Best Components of Previous Sonus and telecom technologies Partner Programs; Multi-Tiered Program Structure and Interoperability Lab Are Cornerstones of New Program
WESTFORD, Mass.--(BUSINESS WIRE)--March 19, 2001-- Sonus Networks (Nasdaq: SONS - news), a leading provider of voice infrastructure solutions for the new public network, today launched a new and improved program structure for its Open Services Partner Alliance(TM) (OSPA), designed to deliver even greater value to both service providers and partners alike. In related news, Sonus also introduced several new members joining the OSPA program, as well as a number of companies who have achieved ``Powered`` status through successful interoperability testing with Sonus (See today`s press releases ``Sonus Networks Expands Open Services Partner Alliance with Addition of Eleven Telecom Vendors`` and ``Sonus Networks Designates ``Powered`` Status to Four Alliance Partners``).

The new OSPA now combines Sonus` original partner program with the INIP Powered(SM) Partner Program, which was gained through Sonus` recent acquisition of telecom technologies, inc. The goal of the OSPA program is to empower standards-based interoperability between applications, infrastructure vendors and the Sonus product suite. The program creates end-to-end, integrated solutions for carriers and service providers and accelerates the time to market for these solutions.

``We believe that both our carrier customers and partners will be excited about the enhancements we`ve made to the Open Services Partner Alliance,`` said Terri Griffin, vice president of marketing, INtelligentIP® division, Sonus Networks. ``Now, more than ever, service providers have the ability to gain the competitive advantage with the explosion of next-generation, packet-based enhanced services provided by Sonus` OSPA partners.``

A major distinction between the revamped OSPA and Sonus` previous partner programs is the combination of a multi-tiered participation structure and Sonus` state-of-the-art OSPA Interoperability Lab. Companies joining the OSPA enter the program as Sonus Partners, which signifies that these vendors provide products and applications that are complementary to Sonus Networks` product family. Sonus Partners may then elect to become Sonus Powered Partners by successfully completing interoperability testing with one of the Sonus Networks products in the OSPA Interoperability Lab in Richardson, Texas. Sonus Powered Partners then have the ability to become Sonus Platinum Partners when they have proven, commercially deployed products interoperating with Sonus solutions in live service provider environments.

The OSPA is the only program of its kind backed by an interoperability lab where standards-based product interoperability can be verified, trial testing can be performed, and complete best-of-breed solutions are produced. Here, telecom vendors can demonstrate next-generation voice and data communications services in a real-world setting and show the ways in which end users benefit from integrated solutions.

``The new OSPA tier structure and interoperability lab address the real issues of carriers and separate the ``truth`` from the ``hype`` in the marketplace,`` continued Griffin.

The new OSPA program now has more than 100 partners offering a wide variety of products that range from network infrastructure and operations support systems (OSS) to next-generation, revenue-generating enhanced services. Through these partnerships, Sonus is committed to offering end-to-end solutions with technologies such as:

OSPA Enhanced Services - provides carriers applications such as access feature servers, call center/ACD, conferencing, Internet call waiting, IP PBX, one number/personal assistant, prepaid and calling card applications, video conferencing, voice/unified messaging, voice portals and many others.
OSPA Network Infrastructure - offers a range of products such as application servers, DSLAMs/DSL modems, gateways, softswitches, IADs, media servers, remote access servers, routers, phones, SIP infrastructure products and more.
OSPA Operations Support Systems (OSS) - includes solutions such as billing mediation platforms, usage-based billing services, service level management, policy engines and provisioning systems.
The Sonus OSPA provides a framework that enables service providers to deploy end-to-end packet voice networks using best-of-breed technologies and applications. By deploying Sonus` market-leading packet-based network solutions, service providers are well positioned to capture market share with the plethora of next-generation packet-based infrastructure and services provided by OSPA members.

Time Warner Telecom Begins Traffic Flow On Sonus-Based Infrastructure
Carrier Has Deployed Sonus Voice Solutions in Eight U.S. Markets to Deliver Dial-up Internet Access; Business-Class Voice Services to Follow
WESTFORD, Mass.--(BUSINESS WIRE)--April 9, 2001-- Time Warner Telecom Inc. (Nasdaq: TWTC - news), a leader in providing local and regional optical broadband networks and services to business customers, and Sonus Networks (Nasdaq: SONS - news), a leading provider of voice infrastructure solutions for the new public network, today announced that Time Warner Telecom has deployed Sonus` packet telephony product family, including softswitches and media gateways, in eight markets throughout the United States. Time Warner Telecom is now delivering revenue-generating traffic over those networks.

``We are pleased with the progress that we are making with Sonus in rolling out our next-generation service delivery architecture,`` said Mike Rouleau, Time Warner Telecom`s senior vice president, marketing and business development. ``Our Sonus-based network provides a platform through which we meet our immediate and future requirements for Internet dial-up traffic, and with the expectation that it will allow us to deliver a wide range of enhanced voice and data services in the future.``

Time Warner Telecom selected Sonus in the third quarter of 2000 as one of its primary suppliers for voice infrastructure solutions to deliver business class telephony services and Internet `dial tone.` At that time, Time Warner Telecom began installation of Sonus` range of packet voice solutions, as well as Riverstone Networks` RS series of switch routers. Using the combined Sonus/Riverstone solution, Time Warner Telecom has rapidly expanded its packet telephony footprint to eight markets throughout the U.S. The Sonus/Riverstone systems have been deployed in San Diego, Calif.; Austin, Texas; Binghamton and New York, N.Y.; Cincinnati and Columbus, Ohio; Indianapolis, Ind.; and Milwaukee, Wisc.

Time Warner Telecom sought a complete packet telephony solution last year that would allow the carrier to achieve the highest levels of scalability, performance, and reliability. Through a reseller arrangement, Sonus teamed with Riverstone to provide Time Warner Telecom with a robust, NEBS Level 3-certified core network system, comprising Sonus` GSX9000(TM) Open Services Switch, PSX6000(TM) SoftSwitch, SGX2000(TM) SS7 Signaling Gateway and the Riverstone RS series of switch routers. This combination of products enables Time Warner Telecom to deploy large switch sites, rapidly and cost-effectively, each capable of handling more than 100,000 telephone calls.

Time Warner Telecom is initially leveraging the Sonus-based network to augment its existing Class 5 circuit switches and offload modem-generated Internet traffic from its voice network. Time Warner Telecom also plans to use the Sonus infrastructure to deliver traditional local and long-distance services, as well as new voice over IP-based services such as unified communications, single number service, call centers, and more.

``Time Warner Telecom is recognized as a leading player in the broadband communications industry, and the innovative network we`re building together will enable them to further raise the bar for competitors,`` said Hassan Ahmed, president and CEO, Sonus Networks. ``We look forward to continuing our close collaboration with Time Warner Telecom and helping them to deliver leading-edge products and services to their business customers.``

Time Warner Telecom plans to continue to roll out the Sonus packet voice infrastructure solutions in select markets.

Q1 Revenues Grow to $41.5 Million, Increase 45% Over Preceding Quarter
WESTFORD, Mass.--(BUSINESS WIRE)--April 10, 2001--Sonus Networks, Inc. (Nasdaq:SONS - news), a leading provider of voice infrastructure solutions for the new public network, today reported financial results for its first quarter ended March 31, 2001.

Revenues for the first quarter of fiscal 2001 were $41.5 million compared with $28.6 million for the fourth quarter ended December 31, 2000, an increase of 45 percent. Net income for the first quarter of fiscal 2001, excluding stock-based compensation, amortization of goodwill and purchased intangibles and an in-process research and development charge relating to the acquisition of telecom technologies, inc., completed in January 2001, was $0.2 million or $0.00 per share, compared with net income, excluding stock-based compensation, of $0.1 million or $0.00 per share on a pro forma basis for the fourth quarter of fiscal 2000.

Net loss for the first quarter, including stock-based compensation, amortization of goodwill and purchased intangibles and an in-process research and development charge, was $82.5 million or $0.51 per share, compared with a net loss of $6.3 million or $0.04 per share for the fourth quarter of fiscal 2000.

``We are extremely gratified with our results this quarter,`` said Hassan Ahmed, president and CEO, Sonus Networks. ``During the quarter, we continued to execute on our business strategy and have made significant progress across several fronts. We expanded our customer base, delivered new product capabilities and features, broadened our partner program and have made great strides in the integration of telecom technologies following the completion of the acquisition in January. We`re off to a great start this year.``

In March, Sonus announced that it signed a multi-year, multimillion-dollar contract with Qwest Communications. Qwest has selected Sonus` packet voice technology for deployment in Qwest`s nationwide, all-optical IP network. Qwest is building its next-generation voice network using the full range of Sonus solutions, including the GSX9000(TM) Open Services Switch, the INtelligentIP® Softswitch, which was gained through the acquisition of telecom technologies, inc., the PSX6000(TM) SoftSwitch and the SGX2000(TM) SS7 Signaling Gateway. Qwest also announced its first suite of services based on the Sonus platform, Qwest CyberVoice Interconnect, a wholesale voice over IP (VoIP) terminating service that enables service providers to deliver clear, reliable voice calls over Qwest`s nationwide broadband Internet network.

Sonus continues to advance its deployments with other carriers. Yesterday, Sonus and Time Warner Telecom announced that Time Warner is now delivering revenue-generating traffic over the Sonus-based infrastructure in eight U.S. markets. Time Warner is initially leveraging the Sonus packet voice solutions to augment its existing Class 5 circuit switches and offload modem-generated Internet traffic from its voice network. Time Warner also plans to use the Sonus infrastructure to deliver traditional local and long-distance services, as well as new voice over IP-based services such as unified communications, single number service, call centers, and more.

Sonus continued to gain momentum in the market for carrier-class packet voice switching equipment, and was again named the worldwide market share leader. Reports issued by industry research firms Cahners In-Stat, Infonetics Research Group and Synergy Research Group confirmed Sonus` market-leading position for the fourth quarter of 2000 and for the full year 2000.

To provide carriers a wide range of options for deploying enhanced voice and data services, Sonus broadened its Open Services Partner Alliance (OSPA) program. The expanded program, which integrates the best components of previous Sonus and telecom technologies partner programs, offers greater value to both service providers and partners through a new multi-tiered participation structure and the state-of-the-art OSPA Interoperability Lab. Sonus also added eleven new partners to the OSPA, and announced that six other partners had successfully completed interoperability testing, achieving Sonus ``Powered`` status in the program.

Luminous Joins Sonus` Open Services Partner Alliance to Offer Carrier-Class Voice and VoIP Metro Solutions
CUPERTINO, Calif., April 16 /PRNewswire/ -- Luminous Networks, the first provider of carrier-class optical Ethernet platforms for Metropolitan Area Networks, today announced that it has joined the Sonus Networks (Nasdaq: SONS - news) Open Services Partner Alliance to provide carriers with a cost-effective, carrier-class voice and VoIP solution. The relationship with Sonus has the potential to revolutionize services provided by today`s telecommunications carriers, as it allows them to offer multiple voice and data services from a common platform.

This combination provides carriers with the first toll-quality, carrier-class voice and VoIP capability on an optical Ethernet metro platform. Luminous` optical Ethernet platform transports aggregated time-division multiplexing (TDM) data traffic through Metropolitan Area Networks (MANs). The Luminous platform then sends the TDM and VoIP traffic to Sonus softswitches and SS7 signaling gateways via the Sonus GSX9000 Open Services Switch for integration into the public switched telephone network (PSTN) and other voice network systems.

``We are delighted to work with Luminous to help deliver carrier-class voice, VoIP, video and data services on a common optical Ethernet platform in Metropolitan Area Networks,`` said Terri Griffin, vice president of marketing programs, Sonus Networks. ``With the addition of Luminous to our partner program, Sonus continues to pursue its goal of empowering standards-based interoperability between multiple network applications and Sonus products.``

Alex Naqvi, president and CEO of Luminous Networks, added, ``As a key architect of VoIP infrastructure solutions for the new public network, Sonus helps carriers reduce equipment costs, minimize physical co-location space, and deliver new revenue-generating services.

Kommunikation – welche Wirtschaftsflaute?


Als innovativer Entwickler von Kommunikationszubehör hat sich Sonus Networks [Nasdaq: SONS Kurs/Chart ] in der Branche längst einen Namen gemacht. Der Börsengang des Unternehmens fiel jedoch in eine Zeit (Frühjahr 2000), als sich die Euphorie für Hightech-Aktien bereits merklich abgekühlt hatte. Aus diesem Grund dürfte Sonus auch den wenigsten deutschen Anlegern ein Begriff sein.

Dabei ist die Firma absolut einen Blick wert. Sonus entwickelt Soft- und Hardware, die Telefongesellschaften, Internet-Service-Providern und Kabelnetzbetreibern den effektiven Transport von Daten ermöglichen. Weitere Geschäftsfelder umfassen die Installation von Netzwerken, den Support und die Schulung von Mitarbeitern.

Beim Kommunikationszubehör setzt Sonus auf eine Technologie, die Dateien vor dem Transport in viele kleine "Päckchen" zerhackt. Die Pakete erhalten anschließend jeweils Informationen mit der Adresse des Empfängers und eine Art Teilenummer. Beim anschließenden Versand müssen daher nicht alle Daten auf einmal über die gleiche Leitung transportiert werden, sondern können über verschiedene Wege den Empfänger erreichen – das spart Zeit und Geld. Einmal angekommen werden die einzelnen Sendungen mit Hilfe der übermittelten Informationen wieder zusammengesetzt.

Zu den Kunden des Unternehmens zählen unter anderem Global Crossing, Qwest Communications und AOL Time Warner. Mit Qwest hat Sonus im März einen besonders dicken Fisch an Land gezogen. Der Carrier wird die gesamte Produktpalette von Sonus für das Upgrade seines Glasfaser-Datennetzwerks nutzen. Weitere Deals mit großen Telefongesellschaften befinden sich dem Unternehmen zufolge in Vorbereitung.

Anfang April überraschte Sonus die Analysten mit einem Ergebnis über den Erwartungen. Statt eines Verlustes von 0,02 Dollar pro Aktie schaffte das Unternehmen im ersten Quartal den Breakeven. Der Umsatz stieg gegenüber dem vierten Quartal 2000 um 45 Prozent auf 41,5 Millionen Dollar.

Fazit: Mit einem Umsatzvielfachen von 30 auf Basis der diesjährigen Prognosen ist Sonus happig bewertet. Im Gegenzug erhalten die Anleger ein hochinnovatives Unternehmen, das von der anhaltenden Wirtschaftsflaute bisher nichts mitbekommen hat und sich selbst gegen Konkurrenten wie Cisco und Nortel erfolgreich zur Wehr setzen kann. In seinem Kerngeschäft nimmt Sonus trotz seiner noch jungen Firmengeschichte Marktforschern zufolge bereits jetzt eine Ausnahmestellung ein.

Fusion Communications Corp. First to Deploy Sonus Networks` Packet Voice Network in Japan
Next-Generation Japanese Carrier Develops Largest Nationwide, Converged IP Network; After First Month of Service, Network Supports More Than 360,000 Subscribers
TOKYO & WESTFORD, Mass.--(BUSINESS WIRE)--May 15, 2001-- Sonus Networks (Nasdaq: SONS - news) today announced that Fusion Communications has deployed Sonus` voice infrastructure solutions as the foundation of their next-generation voice network, which began delivering live traffic last month. Sonus is supplying Fusion a full range of packet voice solutions under a multi-million dollar, multiyear relationship.

``We have built a highly sophisticated and efficient network that leverages the most innovative network architecture and solutions,`` stated Tadahisa Sumida, president and CEO, Fusion Communications Corp. ``We thoroughly evaluated the solutions available today and found that only Sonus` products met our requirements for scalability, performance and reliability. Sonus` family of voice infrastructure solutions not only enabled us to reduce the cost and time involved in building our network, but have also allowed us to quickly deliver revenue-generating voice and data services.``

Fusion was established in March 2000 with the mission of becoming Japan`s first and premier IP-centric telecommunications carrier, providing services to business and domestic phone users in Japan. Utilizing advanced packet technologies, Fusion has rapidly developed the largest nationwide VoIP network and is Japan`s first carrier to support the integrated transmission of voice and data.

Working together with Sonus and its distribution partner, Nissho Electronics, a leading network integrator in Japan, Fusion implemented Japanese versions of Sonus` award-winning GSX9000(TM) Open Services Switch, PSX6000(TM) SoftSwitch and SGX2000(TM) SS7 Signaling Gateway throughout its network. Initially, Fusion has rolled out the Sonus systems in 17 cities across Japan, with plans to rapidly build out a network footprint that will encompass all major cities and population centers. Launched just last month, the Fusion network already supports more than 360,000 subscribers.

By deploying Sonus` Open Services Architecture(TM) (OSA) and voice infrastructure solutions throughout its fiber-optic network, Fusion will be delivering to its customers a full complement of traditional voice services such as long distance telephone service, international telephone service, VPN and virtual ISP. Additionally, Fusion plans to offer a range of innovative, enhanced voice over packet services including IP phone connectivity and unified communications, among others. In the second phase of the network, with the construction of a high-speed broadband fiber-optic backbone, Fusion plans to provide an environment that will enable rich multi-media broadband content services.

``We are extremely pleased to be working with Fusion in this tremendously exciting endeavor, the development of Japan`s first national packet voice network,`` said Hassan Ahmed, Sonus` president and CEO. ``With their aggressive buildout plans, Fusion is setting the standard for other carriers in Japan and is revolutionizing the communications landscape. By equipping itself with world-class technology, Fusion is positioned to become a world-class player.``

About Fusion Communications Corp.

Fusion Communications Corporation is a next-generation Japanese telecommunications carrier focusing on IP technology. Fusion was founded in March 2000 and began services on April 1, 2001. Their mission is to create a world-class, high-quality, cost-effective telecommunications environment in Japan. Starting with a nationwide IP network which they have single-handedly built, they are progressing toward the global trend of an integrated IP telecommunications infrastructure which brings down the cost of various telecommunications services such as voice, data, internet access and converged service applications.

In July 2000 Fusion obtained a ``Type-1 Telecommunications Carrier License`` and a license for ``Fixed Wire Access - FWA``, and in addition, they have been given a carrier identification number. Fusion`s first service offering, which went live on April 1, 2001, was the nationwide ``0038`` long distance service. This Fusion service represents a first in Japan, as this service is not dependent on distance. Existing carriers in Japan services are dependent on distance. Fusion is the first carrier with a uniform rate nationwide at 20 yen per three minutes at all times of the day. Fusion has also been registered as a carrier under the ``My Line/My Line Plus`` carrier selection service in Japan, which began on May 1, 2001.

Leading Research Firms Name Sonus Networks Number One Provider of Carrier-Class Packet Voice Solutions
Cahners In-Stat, Infonetics and Synergy Research Group Name Sonus #1 for Third Consecutive Quarter; Company Maintains Commanding Lead in Packet Voice Market
WESTFORD, Mass.--(BUSINESS WIRE)--June 4, 2001-- Sonus Networks (Nasdaq: SONS - news) today announced that it has been ranked the worldwide market share leader for carrier-class packet voice switching equipment for the first quarter of 2001. Reports issued recently by industry research firms Cahners In-Stat Group, Infonetics Research and Synergy Research Group confirm Sonus` continued leadership position in a number of market segments.

``We continued to make tremendous progress with our customers in the first quarter, expanding our deployments with current carrier customers and forging relationships with new customers,`` commented Stephen Collins, vice president, marketing, Sonus Networks. ``We are extremely gratified to again be recognized by these highly respected research firms for our leading industry position.``

Cahners In-Stat Group released its first quarter market share report last week, with data showing Sonus as continued leader in purpose-built carrier VoIP gateways, in both ports and revenues. Based on the numbers in the Cahners report, Sonus continued to outpace other players in the industry, while competitors` shares were flat or declined in the last quarter.

``Sonus continues to ramp its voice gateway port shipments from one quarter to the next even in a difficult telecom service provider environment in which many other firms find their shipments declining,`` said Norm Bogen, director, WAN Infrastructure and Services, Cahners In-Stat Group.

In May, Infonetics Research issued its quarterly worldwide market share and forecast service, and named Sonus number one in next generation voice/data switch revenues. In this report, Infonetics noted that Sonus continued to expand its lead over its nearest competitors, growing its market share by an additional 15 percent from the previous quarter.

``While we believe overall service provider capital expenditures will experience a short period of decline during 2001, we are seeing a shift from legacy TDM equipment to next-gen voice products,`` said Michael Howard, principal analyst and co-founder, Infonetics Research. ``Sonus is well positioned to benefit from this shift, and this is borne out by the fact that Sonus continued to expand its market leadership in the first quarter, capturing 66% of next-gen voice/data switch revenues.``

Synergy Research Group also named Sonus the leader in its quarterly report on voice over IP (VoIP) equipment market share. Synergy ranked Sonus number one in several market segments including: total worldwide VoIP port shipments; service provider VoIP gateway port shipments; high density VoIP gateway revenues and port shipments; and combined high density VoIP/Internet Call Diversion revenues.

``Sonus made considerable headway during the first quarter of the year,`` noted Jeremy Duke, founder and principal analyst, Synergy Research Group. ``Sonus is the vendor gaining traction in the market, and this momentum is clearly reflected in its market share across a number of segments.``

Sonus delivers a complete family of carrier-class, packet voice infrastructure solutions for the new public network. The company`s award-winning solutions include the GSX9000(TM) Open Services Switch, the PSX6000(TM) SoftSwitch, the INtelligentIP® Softswitch, the SGX2000(TM) SS7 Signaling Gateway, and Sonus Insight(TM) Element Management System.

Sonus Networks Provides Internet Call Diversion Solution for BellSouth
Sonus Equipment Enables Leading RBOC to Efficiently Manage Internet and Voice Traffic
WESTFORD, Mass.--(BUSINESS WIRE)--July 11, 2001--Sonus Networks (Nasdaq: SONS - news) today announced that BellSouth Corporation (NYSE: BLS - news) has chosen Sonus` award-winning packet voice infrastructure solutions to further enhance BellSouth`s data services. BellSouth will implement a Sonus packet voice solution as the foundation for offloading Internet traffic from its circuit-switched voice network.

``BellSouth is aggressively transforming its network to meet the demands of new data services, while continuing to provide efficient voice applications,`` said Ray Smets, vice president of Network Transformation for BellSouth Corporation. ``Sonus` ICD solution is a critical step in BellSouth`s network migration to support more packet-based data services.``

BellSouth plans to deploy Sonus solutions that include the GSX9000(TM) Open Services Switch, the PSX6000(TM) SoftSwitch, the SGX2000(TM) SS7 Signaling Gateway and the Sonus Insight(TM) Element Management System. BellSouth will utilize Sonus technology to supplement its existing Class 5 circuit switches, offloading modem-generated Internet traffic from its voice network. In this application, Internet traffic destined for remote access servers is diverted away from circuit switches before it enters the voice infrastructure, thus freeing up network resources. With the new packet-based infrastructure in place, BellSouth also has the ability to expand beyond the initial Internet call diversion application to deliver voice services on the same packet platform.

``In deploying a packet-based infrastructure, BellSouth furthers its reputation as one of the most innovative and technologically advanced of the Regional Bell Operating Companies (RBOCs),`` said Hassan Ahmed, president and CEO, Sonus Networks. ``We are gratified to have been selected by BellSouth as their vendor of choice for the ICD project.``

BellSouth is expected to deploy Sonus ICD solutions in at least 8 major metro areas within the Southeast in the next year.

``Implementing the Internet Call Diversion solution from Sonus will relieve potential pressure points in BellSouth`s network that could be caused by large volumes of traffic destined for the Internet,`` said Christin Flynn, director, Carrier Convergence Infrastructure, the Yankee Group. ``Furthermore, this architectural decision opens up the opportunity for BellSouth to deliver packetized voice services in the future, enabling enhanced, revenue-generating services they cannot offer today. For Sonus, this represents a significant turning point. The company takes on the network of a demanding class of customer with high reliability requirements: the local incumbents.``

BellSouth Corporation is a Fortune 100 communications services company headquartered in Atlanta, GA, serving more than 45 million customers in the United States and 16 other countries.

BroadSoft One of First Companies to Achieve Platinum Status in Sonus Networks` Open Services Partner Alliance
WESTFORD, Mass. and GAITHERSBURG, Md.--(BUSINESS WIRE)--July 17, 2001--

Pioneering IP Services Provider, Exario Networks, Deploys
Comprehensive Sonus and BroadSoft Solution to Deliver Enhanced Voice

Services to Enterprise Customers

Sonus Networks (Nasdaq: SONS - news), a leading provider of voice infrastructure solutions for the new public network, and BroadSoft, Inc., the leading provider of carrier-class service delivery systems for packet-based enhanced telephony services, announced today that BroadSoft has attained Platinum Partner standing in Sonus` Open Services Partner Alliance(TM) (OSPA).

BroadSoft is one of the first companies to meet all of the criteria to become a Sonus Platinum partner. To attain Platinum status, companies must have products and applications complementary to Sonus` product family and achieve Powered status by successfully completing interoperability testing in the OSPA Interoperability Lab. Most importantly, Sonus Platinum partners` solutions must be deployed in a live service provider network together with a Sonus product. Exario Networks, a leading provider of outsourced IP services based in Parsippany, New Jersey, has implemented the Sonus/BroadSoft solution to deliver converged voice and data private IP solutions to its enterprise customers.

By deploying Sonus` voice infrastructure solutions, including the GSX9000(TM) Open Services Switch and the PSX6000(TM) SoftSwitch and the BroadSoft BroadWorks(TM) service delivery system to augment its existing Class 4 IP tandem nationwide network, Exario has expanded its voice offerings to the enterprise market to provide an enhanced suite of advanced IP network solutions. Exario has also integrated an extensive set of web-enabled enhanced telephony services into its proprietary web-based network management platform, the Exario virtualNOC, including conferencing, call forwarding, voice mail, follow-me-anywhere calling, and auto attendant.

``Leveraging the power of the easy-to-use, flexible BroadWorks service delivery system coupled with the unparalleled quality of Sonus` voice infrastructure products, allows us to differentiate our service offerings and stay ahead of the competition,`` said Tom Mizzone, CEO of Exario Networks. ``The real value of this partnership is that it creates one of the most comprehensive suites of converged services available today and gives Exario`s customers more choices in the services they buy, provision and manage. We view our relationship with these two companies as a key component of our next-generation network strategy.``

Sonus provides a complete packet voice solution that has been designed to carrier standards, delivering toll-quality voice, system redundancy, and the capacity to handle extremely large call volumes. Additionally, Sonus` award-winning voice infrastructure solutions offer a single platform that allows carriers to deliver a range of communications services including traditional long distance and local voice services, wholesale voice services, and enhanced services, such as unified communications, presence management, enhanced voicemail, voice portals and many others.

BroadSoft`s flagship product, BroadWorks, is the industry`s first comprehensive enhanced service delivery system for packet-based business services. BroadWorks enables service providers to rapidly enter new markets and immediately generate new revenues with easy-to-use, differentiated local exchange services over packet-based networks as well as the traditional public switched telephone network (PSTN). BroadWorks includes a rich set of business options such as call waiting, voicemail, conferencing, auto-attendant and follow-me-anywhere services, and can interoperate with other network elements and business applications for a comprehensive set of integrated services without lengthy and expensive proprietary development. By installing BroadSoft`s BroadWorks service delivery system in conjunction with Sonus solutions, carrier customers gain unprecedented flexibility and lower costs as they strive to offer innovative, customized, enhanced services to their business customers.

``We are pleased that BroadSoft has met our Platinum Partner requirements and we are excited that our combined solution is operating today in Exario`s revenue-generating network,`` said Terri Griffin, vice president of marketing programs at Sonus Networks. ``Attaining interoperability with leading vendors such as BroadSoft is fundamental to the proliferation of next-generation voice solutions.``

``BroadSoft is proud to be one of the first Sonus Powered companies to attain Platinum Partner status,`` said Scott Wharton, vice president of marketing for BroadSoft. ``By making BroadWorks fully interoperable with Sonus` industry-leading packet voice solutions, our companies are bringing a tremendous market advantage to carriers through superior technology solutions and service differentiation.``

BroadSoft first attained Sonus Powered status in August 2000, after BroadSoft submitted its service delivery and call routing system to Sonus` Interoperability Laboratory, where interoperability with Sonus` equipment was demonstrated through a series of tests. In order to attain Sonus` Platinum Partner status, BroadSoft had to fulfill a number of key requirements including: being commercially deployed in a carrier`s network interoperating with Sonus products; proving carrier-class reliability and scalability; possessing resources to support 24x7 technical support; and offering sales, marketing, and technical resources to support large carrier deployments.

About BroadSoft

BroadSoft, Inc., is the leading provider of service delivery systems for next-generation telephony services. BroadWorks, the company`s flagship product, allows service providers to rapidly and economically design and deploy web-enabled enhanced telephony services to their customers.

By Ben Klayman

CHICAGO (Reuters) - Communications equipment maker Ciena Corp. (Nasdaq:CIEN - news) on Thursday slashed its financial forecasts due to market turmoil, sparking a selloff in its shares and tech stocks overall.

The Linthicum, Maryland-based firm`s cuts to its 2001 and 2002 projections overshadowed a slump in fiscal third-quarter net profits, after accounting for almost $100 million in one-time charges, and a doubling of its operating profits.

Shares of Ciena, which makes equipment that increases the capacity of fiber-optic telecom networks, had lost more than 32 percent of their value by midday Thursday. The stock, by far the most active issue on Nasdaq, was down $9.07 at $19.05.

The optical networking firm`s stock has slightly outperformed its peer group in the American Stock Exchange Networking index over the past year.

Investors and analysts were startled by the scope of Ciena`s cuts.

``It was inevitable that Ciena would have to reduce its outlook for next year,`` UBS Warburg analyst Nikos Theodosopoulos said. ``The question was always what would the magnitude be. A lot of people were caught off guard.``

OUTLOOK SLASHED

Chief Financial Officer Joseph Chinnici said 2001 earnings would finish in the range of 59 to 64 cents a share, down from the previous forecast of 72 to 75 cents. Analysts were expecting 73 cents, according to market research firm Thomson Financial/First Call.

He said 2002 earnings would be about flat with 2001. Analysts were expecting the company to earn 99 cents a share, according to First Call.

``We don`t have good visibility for the remainder of 2001 or 2002,`` Chinnici said.

President and Chief Executive Gary Smith said 2001 revenues will grow 85 percent to 90 percent from 2000, off from the previous guidance for 95 percent to 105 percent growth. He added Ciena would see 2002 revenue growth in the ``early teens,`` off from the previous forecast of 45 percent to 65 percent growth.

Ciena`s pain was shared by its peers as ONI Systems Corp. (Nasdaq:ONIS - news), Sonus Networks Inc. (Nasdaq:SONS - news), Redback Networks Inc. (Nasdaq:RBAK - news), Juniper Networks Inc. (Nasdaq:JNPR - news) and Cisco Systems Inc. (Nasdaq:CSCO - news) all saw their shares fall on Thursday.

Smith took issue with how great Ciena`s forecast cuts were and emphasized the company continues to outperform its peers.

``I wouldn`t use the word `slash` and I wouldn`t use the word `grim,` he told Reuters. ``First of all, we gave guidance. Most of our competitors did not. Secondly, we`re still forecasting growth. None of our competitors are.``

``I`m not focused on the daily share price,`` Smith added. ``We run our business for the long term. We`ve weathered the storm better than anybody else. We`re not immune from it, but we`ve delivered strong results. I`m not going to apologize for 90 percent revenue growth this year. I`m just not.``

CIENA WAS `COCKY`

One investor said, however, that Ciena set itself up for Thursday`s fall, sticking to overly optimistic growth estimates for spending in the long-distance carrier market, which makes up about 70 percent of Ciena`s business.

``They`ve been a little confident, maybe even a little cocky, even as late as the last quarter,`` said Shawn Campbell, an analyst with Northern Trust Corp.`s asset management arm, which owns a small number of Ciena shares.

Lost in the investor panic over the lower growth forecasts, Ciena`s third-quarter net income after one-time items fell to $5.65 million, or 2 cents a share, from $28.16 million, or 10 cents a share, last year.

The net results included $75.64 million for amortization of goodwill, $22.23 million in deferred stock compensation charges, $1.38 million for amortization of intangible assets and $507,000 for payroll taxes on stock option exercises. Also included was a $6.58 million benefit from receipt of a previously written-down receivable.

Excluding one-time charges, Ciena`s operating results surged to $58 million, or 17 cents a share, in the quarter ended July 31, from $28.8 million, or 10 cents a share, in the same period last year.

Analysts had expected Ciena to earn 16 cents a share, in a range of 11 cents to 19 cents, according to First Call.

Revenues for the quarter soared 96 percent to $458.1 million from $233.3 million last year.

However, analysts were concerned that Ciena`s third-quarter gross margin fell more than two percentage points from the previous quarter to 43.3 percent, a larger drop than the company had indicated would occur. Ciena officials said inventory charges were to blame for the decline.

Smith said while the market is likely to continue slowing over the next year, demand for Ciena`s next-generation fiber-optic products will allow the company to take business from competitors that make more traditional gear.

Ciena`s success has been driven in part by demand for CoreDirector, its optical switch that can adapt to handle changing network capacity needs, analysts said.

The company`s results have remained strong up to now amid the slowdown as carriers continue to spend for Ciena`s next-generation gear to help them cut costs, analysts said.

Sonus Networks Establishes Japanese Subsidiary
Sonus Furthers Reach in Asia Pacific Region with New Tokyo Operations
WESTFORD, Mass.--(BUSINESS WIRE)--Aug. 27, 2001--Sonus Networks (Nasdaq: SONS - news), a leading provider of voice infrastructure solutions for the new public network, today announced that it has formed a Japanese subsidiary, Nihon Sonus Networks K.K., based in Tokyo. The company also announced that it has named Takayuki Oshima to head up its Japanese operations.

Sonus` direct operations in Tokyo, which include sales, marketing and support functions, will complement the company`s existing alliances with leading Japanese distribution and development partners. Sonus has forged relationships with Nissho Electronics Corporation and Sumitomo Corporation, under which they sell and support the full range of Sonus packet voice solutions to the Japanese carrier market. A year ago, Sonus formed a partnership with Nissho Electronics Corporation and NTT COMWARE Corporation to jointly develop a localized version of the Sonus product family, including the GSX9000(TM) Open Services Switch, the PSX6000(TM) SoftSwitch and the SGX2000(TM) SS7 Signaling Gateway, incorporating key features and functionality for the Japanese market.

``By increasing our presence in Japan, we will be better able to support our current customers in the region, including Fusion Communications and Global Crossing, as they deploy next-generation voice networks,`` said Gary Rogers, vice president, worldwide sales, Sonus Networks. ``The additional resources we`re putting into place enhance our position as we pursue opportunities with both established and new next-generation carriers in Japan.``

Sonus has already achieved considerable success in Japan through its groundbreaking work with Fusion Communications, considered the country`s first next-generation carrier. In April, Fusion launched a nationwide, Sonus-based packet voice network with switches deployed initially in 17 cities in Japan. Today, Fusion`s highly sophisticated all-IP network infrastructure delivers flat rate long distance service to more than 550,000 subscribers, and the carrier plans to grow its subscriber base to 1 million customers by the end of fiscal year 2001 (March 2002).

To lead Sonus` efforts in Japan, the company has appointed Takayuki Oshima president of Nihon Sonus Networks K.K. In this role, Oshima will support Sonus` existing customers in their network deployments, develop relationships with other leading telecommunications providers, and manage Sonus` distribution and development partnerships. Oshima brings to Sonus significant experience in the Japanese telecommunications industry. Prior to joining Sonus, Oshima spent more than eight years in various sales and support roles for Lucent Technologies and AT&T, most recently as country manager for Japan for Lucent`s Software Product Group. In this role, he was responsible for overseeing the business unit`s Japanese operations and successfully introduced new products, including mission-critical billing systems, into various Japanese telecommunications carriers.

Sonus Networks Named Leading Provider of Carrier-Class Packet Voice Solutions
Leading Research Firms Cahners In-Stat, Infonetics and Synergy Research Group Rank Sonus Number 1 for Fourth Consecutive Quarter
WESTFORD, Mass.--(BUSINESS WIRE)--Sept. 5, 2001-- Sonus Networks (Nasdaq: SONS - news) today announced that it has been ranked the worldwide market share leader for carrier-class packet voice switching equipment for the second quarter of 2001, its fourth consecutive quarter in this position. Reports issued by industry research firms Cahners In-Stat Group, Infonetics Research and Synergy Research Group confirm Sonus` continued leadership position in a number of market segments.

``The findings from Cahners, Infonetics and Synergy continue to reflect our strong momentum in the market and the growing demand for our packet voice solutions by carriers,`` said Terri Griffin, vice president, marketing, Sonus Networks. ``We are very proud of our leading industry position and the recognition we have received by these highly respected research firms for that achievement. Paying close attention to customer needs and aggressively executing on our product development and sales strategies continue to drive our success.``

Data from Cahners In-Stat Group`s quarterly market share report identified Sonus as the continued leader in purpose-built carrier voice over IP (VoIP) gateways, in both port shipments and revenues, as well as the leader in total voice over packet (VoP) gateway ports shipped in all product segments. The results from the second quarter report revealed Sonus` market growth over the previous quarter and confirmed its expanding lead over competitors in these categories.

``Sonus continues to outperform competitors and expand its market lead for delivering carrier-class VoIP gateways,`` said Norm Bogen, director, WAN Infrastructure and Services, Cahners In-Stat Group. ``Competitive players have not been able to match Sonus` performance in terms of ports or revenues, demonstrating carriers` confidence in Sonus solutions as a means to reduce costs and expand services during the current industry slump.``

Infonetics Research`s worldwide market share and forecast service reported that Sonus captured two-thirds of next generation voice/data switch revenues in the second quarter, maintaining Sonus` status as the market leader in this segment. Highlighting Sonus` increased traction with customers, the results of the report illustrated Sonus` growing market share over the previous quarter in contrast to competitors` shares, which declined or remained flat.

``Sonus has built a solid lead in the next generation voice/data switching segment and gained considerable ground during the last quarter with adoption of their solutions by leading carriers,`` said Infonetics research analyst Kevin Mitchell. ``With service providers deploying next-gen voice products in order to competitively differentiate their offerings and reduce operational costs, it is significant to note that 8 out of the 32 Tier 1 service providers in the US and Canada have chosen to implement Sonus` solutions. This customer base has helped Sonus retain their revenue leading position for the fourth straight quarter in the voice/data switch market.``

Sonus` market leadership was also recognized by Synergy Research Group`s quarterly report on VoIP equipment market share. In the report, Sonus received top rankings in several market segments including: service provider VoIP gateway revenues and port shipments; high density VoIP gateway revenues and port shipments; and combined high density VoIP/data media gateway revenues.

``With its first to market advantage, pedigree customer list, and increasing acceptance of packet-voice technology, Sonus is in a sustainable leadership position as exemplified in its consistent market share gains quarter after quarter,`` said Jeremy Duke, founder and principal analyst, Synergy Research Group.

Sonus Networks Updates Business Outlook
WESTFORD, Mass.--(BUSINESS WIRE)--Sept. 26, 2001--Sonus Networks (Nasdaq: SONS - news), a leading provider of voice infrastructure solutions for the new public network, today provided an update on its business and financial outlook for the third and fourth quarters of fiscal year 2001.

As a result of the recent deterioration of the telecommunications market, Sonus now expects revenues to be approximately $40 million for the third quarter, which will end on September 30, 2001. This forecasted result represents an increase of more than 150% over the same period last year. Based on these revenues, the Company expects to report an adjusted net loss of approximately $0.05 to $0.07 per diluted share for the quarter, excluding restructuring and non-recurring charges, amortization of goodwill and purchased intangibles, stock-based compensation and an in-process research and development charge.

The Company now expects to achieve full-year 2001 revenues of approximately $170 to $180 million, more than three times the $52.6 million reported for fiscal year 2000. Adjusted net loss for fiscal 2001 is expected to be in the range of $0.08 to $0.10 per diluted share, excluding restructuring and non-recurring charges, amortization of goodwill and purchased intangibles, stock-based compensation and in-process research and development charges.

In light of the current market conditions, Sonus Networks is aligning its cost structure with its revised business outlook, taking a restructuring and one-time charge of up to $31 million. These reductions will not compromise Sonus` continued product innovation or market focus. The Company also expects to record additional non-cash charges of up to $435 million in the third quarter as it accelerates the write-downs and write-offs of goodwill and other intangibles and deferred charges.

``The transformation of the world`s telecommunications network is well under way and presents a major and long-lived opportunity for Sonus,`` said Hassan Ahmed, president and CEO, Sonus Networks. ``While carriers have recently slowed their spending as they reassess their business outlook, Sonus offers a powerful value proposition. We continue to lead the market with innovative technologies, a marquee customer base and strong competitive position, and we maintain our focus on broadening our leadership. Our view of the long-term opportunity has not changed.``

Sonus Networks reports third-quarter loss

WESTFORD, Mass., Oct 11 (Reuters)- Network equipment maker Sonus Networks (NasdaqNM:SONS - news) on Thursday
reported a $498 million third-quarter net loss, or $2.81 per share, which includes a huge charge related to acquisitions and
goodwill.

This compared to a loss of $12.4 million, or 9 cents a share, a year ago.

Excluding restructuring charges, amortization of goodwill and other special items, adjusted net loss for the period was $11.4 million, or 6 cents a share, compared
with an adjusted net loss of $5.4 million, or 4 cents a share, a year ago.

Analysts surveyed by First Call estimated that the Westford, Massachusetts-based company`s per-share loss would be in a range of 5 cents to 7 cents, with a
consensus of 6 cents. Last month, Sonus warned it would post a third-quarter loss with sales more than 25 percent below expectations due to the deepening slump
in the telecommunications market.

Revenues for the third quarter of fiscal 2001 were $40.3 million compared with $15.6 million in the year-ago period.

[e-mail] Networks Elevated to Platinum Partner Status in Sonus Networks` Open Services Partner Alliance
WESTFORD, Mass. & SUNNYVALE, Calif.--(BUSINESS WIRE)--Oct. 15, 2001--

Company Reaches Highest Partner Level Through Deployment With Sonus in Fusion Communications` Full-Scale IP Network in Japan; Sonus
and Juniper Networks Offer Complete Carrier Core Network Solution

Sonus Networks (Nasdaq: SONS - news), a leading provider of voice infrastructure solutions for the new public network, and Juniper Networks, Inc. (Nasdaq: JNPR - news) a leading provider of next-generation Internet Protocol (IP) infrastructure systems, announced today that Juniper Networks has achieved Platinum Partner status in Sonus` industry-leading Open Services Partner Alliance(SM) (OSPA).

Juniper Networks is one of the first companies to meet all of the criteria to become a Sonus Platinum partner. To attain Platinum status, companies` solutions must complement the Sonus platform and they must be deployed in a live service provider network together with one or more Sonus products. Juniper Networks and Sonus have built out the all-IP voice and data network that next-generation Japanese carrier Fusion Communications rolled out earlier this year.

Deploying Juniper Networks M-series routers along with Sonus` packet voice solutions, Fusion created a robust, carrier-class IP network that currently delivers long-distance voice traffic throughout Japan and to other international markets. The network also is poised to support a variety of next-generation services, such as unified messaging, prepaid calling, dial-up access to remote application servers and toll-free calling. Fusion has more than 700,000 long-distance subscriber lines, and plans call for that number to increase to 1 million in the first quarter of 2002.

The strength of the Sonus/Juniper Networks solution has enabled Fusion to gain a first-mover advantage in Japan`s newly deregulated telecommunications environment.

``The speed and stability of Juniper Networks Internet routers, coupled with the performance, reliability and top quality of Sonus` voice infrastructure products, have been important drivers in our success as Japan`s leading next-generation carrier,`` said Yoshiaki Hirayama, general manager of Fusion Communications` Network Engineering division. ``We view our relationship with these two industry-leading companies as a key component of our next-generation network strategy.``

Sonus provides a complete packet voice solution that has been designed to carrier standards, delivering toll-quality voice, system redundancy, and the capacity to handle extremely large call volumes. The Sonus solutions installed in the Fusion network include Japanese versions of its award-winning GSX9000(TM) Open Services Switch, PSX6000(TM) SoftSwitch and SGX2000(TM) SS7 Signaling Gateway. Sonus` voice infrastructure solutions offer a single platform that allows carriers to deliver a range of communications services including traditional long distance and local voice services, wholesale voice services, and enhanced services, such as unified communications, presence management, enhanced voicemail, voice portals and many others.

Juniper Networks M-series Internet backbone routers are purpose-built to meet the unique challenges of the new IP infrastructure. These routers are used in critical applications, such as core routing, dedicated access, peering, and data center hosting by the world`s largest service providers. They share common JUNOS Internet software, features, and technology for full compatibility across all platforms. All platforms support the Internet Processor II ASIC, delivering predictable performance with rich packet processing, such as filtering, class of service, policing, class-based forwarding, rate limiting, and sampling, even during adverse network conditions. Designed specifically for the specialized needs of high-growth, high-speed service providers, M-series routers enable customers to cost-efficiently scale networks to meet growing bandwidth and IP service requirements.

``For carriers to take full advantage of packet voice`s superior cost and feature benefits, they need to build the kind of solid, reliable IP infrastructure that Juniper Networks provides,`` said Terri Griffin, vice president, marketing, Sonus Networks. ``We are proud to have Juniper Networks as a Platinum Partner, and we look forward to working together on future opportunities.``

``We are proud to be associated with one of the premier partner programs in the industry,`` said John Riedel, vice president, Business Development, Juniper Networks. ``Collaborating with Sonus, and with the OSPA, we can help carriers take advantage of the new IP infrastructure to realize their vision of delivering differentiated revenue-generating services.``

Mexican Carrier Alestra Selects Sonus for Next-Generation Packet Voice Network
AT&T-backed Joint Venture Will Start By Introducing Internet Call Diversion Solution; Sonus Equipment Will Enable Alestra to Roll Out Complement of Next-Generation Telephony Services
MEXICO, D.F. and WESTFORD, Mass.--(BUSINESS WIRE)--Nov. 12, 2001-- Alestra and Sonus Networks (Nasdaq: SONS - news) today announced that Alestra, a joint venture between AT&T (NYSE: T - news) and Mexican financial and industrial institutions Bancomer and ALFA, has chosen Sonus as one of its equipment suppliers in the development of Alestra`s packet-based voice network. As part of a multi-million dollar project, Alestra will implement a full range of Sonus packet voice solutions to initially offload Internet traffic from their circuit switched network. The Sonus technology will be a key component of the ``next-generation`` infrastructure that is being deployed by Alestra to expand its data and voice services portfolios.

``We need an infrastructure that will enable us to maintain the highest availability of our Internet dial up services in order to increase our network capacity over the next three years and roll out new services over time,`` said Ricardo Pineda, CTO, Alestra. ``Sonus is the supplier that best met our requirements for scalability, performance, reliability and cost. Sonus has a proven track record, deploying next-generation solutions for many of the best-known U.S. and international carriers, and it has demonstrated a full commitment with the development of our network.``

Alestra is deploying a full range of Sonus` award-winning voice infrastructure solutions, including the GSX9000(TM) Open Services Switch, the PSX6000(TM) SoftSwitch, the SGX2000(TM) SS7 Signaling Gateway and the Sonus Insight(TM) Element Management System.

Alestra will initially leverage the Sonus-based network to augment its existing Class 5 circuit switches, offloading modem-generated Internet traffic from its voice network. In this application, Internet-bound calls destined for remote access servers are diverted away from circuit switches before they enter the voice infrastructure, thus freeing up expensive and limited circuit voice network resources. With the new packet-based voice infrastructure, Alestra is also looking beyond the initial Internet call diversion application to deliver voice and data services on the same platform.

``We are extremely pleased to be selected as the vendor of choice for Alestra`s packet-voice network,`` said Hassan Ahmed, president and CEO, Sonus Networks. ``With the backing of AT&T, Alestra is well positioned to take advantage of a major opportunity to serve as a leader in Mexico`s growing market for next-generation telecommunications services. We look forward to working together to help Alestra transform its network, to generate new revenues and deliver new, competitive services to its Mexican customers.``

Alestra has begun deployment of the Sonus solution for Internet call diversion in major Mexican markets. The company plans to build out its infrastructure further over the next few years, and it expects to introduce voice services based on VoIP technology into the Mexican market shortly.

About Alestra

Alestra provides an array of voice, data, IP, and broadband services to both residential and business customers in Mexico. The company was founded in 1996 to introduce AT&T world-class telecommunications services, including long-distance phone service, in Mexico.

Sonus Networks Completes Telcordia OSMINE Services Process
Completion of OSMINE Signifies Interoperability with RBOC Networks
WESTFORD, Mass.--(BUSINESS WIRE)--Jan. 7, 2002--Sonus Networks (Nasdaq: SONS - news) today announced that it has successfully completed the Telcordia Technologies, Inc. OSMINE Services process for its industry-leading packet voice infrastructure solutions. Sonus has completed its final phase of the OSMINE process, allowing it to offer full capacity and provisioning integration for Sonus solutions within a Regional Bell Operating Company (RBOC) environment.

Sonus` OSMINE initiative enables RBOCs to provision, monitor and manage Sonus` packet voice solutions, including the GSX9000(TM) Open Services Switch and PSX Policy Server and SGX SS7 Gateway modules of the Insignus(TM) Softswitch, in a seamless fashion. Sonus has completed the Telcordia(TM) TIRKS System for the GSX9000, and the Telcordia(TM) Network Performance Monitor System and Telcordia(TM) Network Capacity Manager System for the GSX9000 and PSX and SGX softswitch modules.

``The interoperability between OSS and network elements is key in helping to manage the complexities of provisioning, engineering and quality of service in next-generation networks,`` said Dennis Tinley, vice president, Customer Solutions, Telcordia. ``The software solutions provided by Telcordia are proven and field tested with the world`s premier service providers. We are pleased to work with Sonus, who clearly recognizes the value of OSS to their customers.``

Equipment manufacturers that offer network elements and operations systems to the RBOCs must be certain that these products interoperate with the RBOCs` large embedded base of operations systems. To facilitate this interoperability, Telcordia Technologies established the OSMINE Services process. This process integrates equipment manufacturers` products with Telcordia-developed operations systems, and encourages systems integration in a multi-vendor environment.

``The OSMINE process is critical to the proliferation of next-generation packet voice infrastructure among incumbent local exchange carriers,`` said Mike Hluchyj, founder and chief technology officer, Sonus Networks. ``RBOCs can be confident that they can deploy Sonus solutions for applications such as interoffice tandem switching, business PBX access and Internet call diversion today, and our equipment will easily and transparently integrate with the carriers` existing back-office systems.``

``Over the years, BellSouth has made significant investments in its back-office systems, from both a cost perspective and from a resources perspective,`` said Steve Turner, director of Network Transformation, BellSouth Corporation. ``While BellSouth is focused on transforming its network to a next-generation infrastructure, it also wants to leverage these past investments in operational systems. By gaining OSMINE compliance, Sonus assures that its solutions will be easily assimilated with BellSouth`s provisioning, billing and management processes, allowing for seamless network deployment.``

BEIJING, China & WESTFORD, Mass.--(BUSINESS WIRE)--Jan. 8, 2002-- Sonus Networks (Nasdaq: SONS - news) today announced that China Netcom has selected Sonus to provide infrastructure solutions for the development of China Netcom`s nationwide packet voice network. China Netcom is deploying Sonus media gateway and softswitch solutions to support the delivery of end-to-end IP voice service over the carrier`s broadband network.

Sonus` deployment with China Netcom follows on Sonus` recent launch of its operations in China. Last month, Sonus established a regional office in Beijing and signed on its first Chinese distribution partner, Photonic Bridges, a systems integration company specializing in next-generation network deployments in China (see December 18, 2001 press release ``Sonus Networks Establishes Operations in China``).

In collaboration with Photonic Bridges, Sonus is providing Sonus` award-winning packet voice solutions to China Netcom, as well as comprehensive customer support services. China Netcom is deploying Sonus` GSX9000(TM) Open Services Switch, the Insignus(TM) Softswitch, including the ASX Access Server and PSX Policy Server modules, and the Sonus Insight(TM) Element Management System.

China Netcom will leverage the Sonus-based infrastructure to deliver a variety of IP based voice services to enterprise customers. China Netcom will be offering IP-to-PSTN and PSTN-to-IP calling for long distance access, supporting a wide range of value-added features on its IP-based infrastructure. China Netcom will also be deploying enhanced next-generation voice services on the network, beginning in Phase 1 of the project and continuing in subsequent phases.

``We are completely focused on delivering cutting-edge products and services to our customers, and required new technology that shares that commitment to innovation,`` said Chareleson Zheng, chief operating officer, China Netcom. ``As a leader in the packet voice market, Sonus offered us the most advanced network solutions available, allowing us to gain a competitive edge in the rapidly growing Chinese telecommunications market.``

China Netcom will initially install the Sonus systems in six cities throughout China: Beijing, Shanghai, Guangzhou, Dalian, Shenzhen and Nanjing. China Netcom plans to aggressively expand this network footprint over the next year to cover major cities and will support a significant number of subscribers throughout China.

``China Netcom had the unique opportunity to build its voice infrastructure from the ground up, using next-generation technologies, such as voice over IP, rather than implementing antiquated legacy equipment,`` said Hassan Ahmed, president and CEO. ``We are thrilled to have been selected by China Netcom for the development of their new voice network, and we look forward to working closely together to help them achieve their business objectives.``

``Q4 marked another good quarter of progress in product development, customer deployments and international expansion, all of which further our market leadership,`` said Hassan Ahmed, president and CEO, Sonus Networks. ``We are well positioned to weather the difficult climate our industry faces today, and we will continue to take the steps necessary to build our financial strength and expand our leadership as the telecom industry emerges from its current economic downturn.``

During the quarter, Sonus significantly advanced its access product strategy with the introduction of the Insignus(TM) Softswitch. The Insignus Softswitch expands upon the industry-leading softswitching technologies that Sonus has been deploying for years, and provides new capabilities for delivering Class 5 services and comprehensive SIP (Session Initiation Protocol) support. Underscoring its commitment to the RBOC (Regional Bell Operating Company) market, Sonus also recently completed the Telcordia(TM) OSMINE Services process, which assures incumbent local exchange carriers that Sonus solutions will seamlessly integrate with their existing back-office systems.

Sonus broadened its customer base with the announcement of two new customers during the quarter. In November, Alestra, a joint venture between AT&T (NYSE: T - news) and Mexican financial and industrial institutions Bancomer and ALFA, selected Sonus to supply equipment for the development of Alestra`s packet-based voice network. In October, Touch America, the broadband network and service provider subsidiary of The Montana Power Company (NYSE: MTP - news), announced that it will use Sonus` softswitch and media gateway systems to build an advanced VoIP network to carry all Touch America voice traffic.

In December, Sonus further expanded its global presence with the launch of the company`s direct operations in China. Sonus established a regional office in Beijing, and also formed a distribution partnership with Photonic Bridges, a leading Chinese systems integrator. Last week, the company announced its first customer win in China. China Netcom has chosen Sonus to provide infrastructure solutions for China Netcom`s nationwide packet voice network, and is deploying Sonus` GSX9000(TM) Open Services Switch, the Insignus Softswitch, including the ASX Access Server and PSX Policy Server modules, and the Sonus Insight(TM) Management System.

Also in December, Sonus reported that it has been ranked the worldwide market share leader in carrier-class packet voice switching equipment for a fifth consecutive quarter. Respected industry research firms Cahners In-Stat Group, Infonetics Research and Synergy Research Group all confirmed Sonus` continuing leadership position in a number of market segments during the third quarter of 2001.

``While these are challenging times for the telecom industry, we are excited about Sonus` prospects in the year ahead,`` continued Ahmed. ``Packet voice technologies from Sonus are vital to our customers` businesses, and the interest in our products is strong. We will continue our focus on delivering the most innovative solutions in the industry, and are driving to expand our business into new geographies and market segments as we further our position as the premier franchise in next-generation voice.``

Sonus Networks Boosts Billing and Security Capabilities in Sonus Insight Management System
Sonus Delivers New DataStream Integrator Module for Billing Mediation; Provides Enhanced Security and Back-Office Features in EMS
WESTFORD, Mass.--(BUSINESS WIRE)--March 25, 2002-- Sonus Networks (Nasdaq: SONS - news), a leading provider of voice infrastructure solutions for the new public network, today announced it is delivering a range of powerful new billing, security, OSS (operations support system) integration, and performance management features in its Sonus Insight(TM) Management System. Available in Sonus` recently introduced Release 4.0 software, these enhancements to Sonus Insight allow carriers to more effectively provision, operate and bill for services on their networks.

``Robust network management capabilities are critical to the seamless deployment and reliable operation of packet voice networks,`` said Mike Hluchyj, founder and chief technology officer, Sonus Networks. ``Sonus Insight addresses carriers` stringent requirements, leveraging next-generation management technologies, while also supporting the legacy systems used by incumbent carriers today.``

The latest version of Sonus Insight incorporates an important new component, the DataStream Integrator (DSI), an advanced billing integration solution providing unique features and tools to expedite back-office integration. The DSI compiles billing data from multiple sources, correlates the data and produces standards-compliant billing streams based on customer-specific services and billing usage criteria. The DSI also supports standard distribution methods such as Telcordia`s Automatic Message Accounting Data Networking System (AMADNS) and can be customized to support any third-party or legacy system.

``Clearly, the ability to bill for services is vital to the success of our business,`` said Guillermo Larios, technology manager, Alestra. ``We sought a complete solution that would enable us to transition telephony services from the circuit to packet network without disrupting our existing billing and customer care infrastructures. Sonus Insight seamlessly integrates our current back-office systems with the Sonus equipment, allowing us to leverage our existing investments while benefiting from the latest technologies.``

Sonus also introduced new system security capabilities in Sonus Insight`s Element Management System (EMS), providing advanced security measures at multiple levels. For example, using Secure Socket Layer (SSL) between users and the EMS provides robust encryption, preventing access from unauthorized personnel. Communication links between the EMS and network elements are also secured through the use of the Secure Shell (SSH) protocol. The User Security Manager offers new features that allow system administrators to more easily define security roles and access restrictions based on organizational structure. Sonus Insight`s ability to integrate with centralized security managers using the RADIUS protocol allow carriers to take advantage of advanced authorization methods such as RSA Security`s RSA SecureID.

As carrier customers continue to deploy Sonus` systems and increase the number of minutes on their networks, robust reporting capabilities become even more critical. To that end, Sonus has made a number of enhancements to Sonus Insight`s reporting features, including the ability to map service level entities to the underlying physical infrastructure. Sonus also provides live inventory reports that allow the carrier to track their investments in real-time. These reports can be viewed from a web browser, exported to the user`s desktop, as well as pushed to an OSS on a scheduled basis. With this release, Sonus also continues to expand its flow-through provisioning capabilities in the areas of automated routing and subscriber provisioning using the latest technologies such as Java RMI and XML/SOAP. Legacy systems can access these same capabilities using Telnet or CORBA IIOP.

Earlier this year, Sonus completed the Telcordia Technologies OSMINE process, allowing it to offer full capacity and provisioning integration for Sonus solutions within a Regional Bell Operating Company (RBOC) environment. Sonus Insight supports a number of Telcordia OSS including the TIRKS, NPM, NCM and NMA systems. In Release 4.0, Sonus Insight provides new OSMINE monitoring capabilities to ensure that mission-critical operations data is transmitted to the Telcordia OSS and that the upstream systems are receiving the data appropriately.

Sonus Networks Reports 2002 First Quarter Financial Results
WESTFORD, Mass.--(BUSINESS WIRE)--April 9, 2002--Sonus Networks, Inc. (Nasdaq: SONS - news), a leading provider of voice infrastructure solutions for the new public network, today reported its actual financial results for the first quarter ended March 31, 2002. These results are consistent with the estimated results the Company provided on March 27, 2002.

Revenues for the first quarter of fiscal 2002 were $21.2 million compared with $41.5 million in the same period last year. Adjusted net loss for the first quarter of fiscal 2002 was $12.8 million or $0.07 per share compared with adjusted net income for the first quarter of fiscal 2001 of $0.2 million or $0.00 per share. Actual net loss for the first quarter of fiscal 2002 was $16.2 million or $0.09 per share compared with an actual net loss for the first quarter of fiscal 2001 of $82.5 million or $0.51 per share.

A reconciliation of adjusted net income (loss) to actual net loss for the periods is as follows:


($ Millions)
Q1-2002 Q1-2001
Adjusted net income (loss) ($12.8) $0.2
Write-off of inventory and purchase commitments (9.4) --
Stock-based compensation (5.7) (15.5)
Amortization of goodwill and purchased intangibles (0.4) (27.2)

Restructuring benefit (charges), net 12.1 --

In-process research and development -- (40.0)

Actual net loss ($16.2) ($82.5)

``The continued deterioration in the telecommunications market impacted our financial results for the quarter,`` said Hassan Ahmed, president and CEO, Sonus Networks. ``We continue to focus on the financial metrics of our company and preserving our financial strength. Beyond the numbers, we made important progress this quarter in building our business fundamentals - driving our industry-leading innovations and increasing the breadth of our customer base.``

Sonus continues to build its portfolio of industry-leading packet voice solutions, and in February, unveiled the Release 4.0 version of its award-winning hardware and software platforms for the GSX9000(TM) Open Services Switch, the Insignus(TM) Softswitch and the Sonus Insight(TM) Management System. Sonus tripled the port capacity of the GSX9000, and added optical interfaces designed for international markets. The newest release of the Insignus Softswitch also delivers robust functionality for global carrier deployments, and now supports nearly 30 different SS7 variants, in addition to international versions of ISDN, PRI and CAS.

Sonus boosted the billing, security and OSS integration capabilities of the Sonus Insight Management System to allow carriers to more effectively provision, operate and bill for services on their networks. As part of the Release 4.0 software, Sonus introduced a new module for Sonus Insight, the DataStream Integrator (DSI), an advanced billing integration and mediation solution.

Also in the quarter, Sonus continued to expand its customer base with the addition of two new customers. Sonus announced that MASERGY, a Dallas-based global communications provider, is implementing a full Sonus packet voice solution in its worldwide IP/MPLS network. In January, China Netcom selected Sonus for the buildout of the carrier`s nationwide packet voice network. China Netcom is deploying Sonus voice infrastructure solutions to support the delivery of end-to-end IP voice services over China Netcom`s broadband network.

Sonus further underscored its commitment to the international markets, forming a distribution partnership with AsiaInfo Holdings, under which AsiaInfo will provide the full range of Sonus products to the Chinese carrier market. This new distribution arrangement augments the direct presence and reseller relationship that Sonus established in China in 2001.

In February, Sonus announced that it had increased its position in the market for carrier-class packet voice equipment, and was ranked the worldwide market share leader for a sixth consecutive quarter. Reports issued by industry research firms Cahners In-Stat/MDR, Infonetics Research and Synergy Research Group verified Sonus` expanded leadership position in a number of market segments for the fourth quarter of 2001, as well as for the full calendar year.

Sonus posts loss, sees third quarter results flat
By Ben Klayman

CHICAGO, July 11 (Reuters) - Telecommunications equipment maker Sonus Networks Inc. (NasdaqNM:SONS - News) on Thursday posted a second-quarter loss amid a spending slowdown in a "challenging" telecom market and said results in the third quarter could be flat.

The company, whose products transport voice traffic over the Internet, expects to post current quarter revenues and a loss before one-time items that are flat with the second quarter, Sonus Chief Financial Officer Stephen Nill told analysts on a conference call.

Sonus then expects the fourth quarter to show modest revenue growth from the third quarter, he added.

Broadly in line with company predictions, Sonus reported a second-quarter loss before one-time items of $10.5 million, or 6 cents a share, compared with a profit in the year-ago quarter of $1.2 million, or 1 cent a share.

Before Nill`s third quarter prediction, the analysts were expecting Sonus to post a loss of 6 cents a share in the third quarter, with a range of loss estimates from 4 cents to 12 cents, according to Thomson First Call. They also were expecting third-quarter revenues of $22.59 million, compared to $21.3 million posted for the second quarter.

Suppliers to the telephone industry have been hurt by drastic spending cuts by carriers, forcing job cuts, financial losses and sales of non-core or money-losing assets. Sonus said it ended the quarter with 497 employees, 7 percent below the previous quarter`s total

Rival Juniper Networks Inc. (NasdaqNM:JNPR - News) posted a second-quarter profit on Thursday and said it saw revenues climbing in the third quarter 32 percent to 37 percent from the previous three-month period.

Analysts said the results from both companies were a good sign, but because they are such small companies an end to the slowdown has not necessarily arrived.

"Is it encouraging? Yeah. Am I ready to declare victory? No," Lehman Brothers analyst Steve Levy said. "In this market for any company to say that things look like they`re stabilizing is encouraging."

With accounting questions dogging WorldCom Inc. (NasdaqNM:WCOME - News) and Qwest Communications International Inc. (NYSE:Q - News), and weak demand hurting Baby Bells like SBC Communications Inc. (NYSE:SBC - News) and BellSouth Corp. (NYSE:BLS - News), analysts and investors have shied away from equipment suppliers.

Before the results were announced, shares of Sonus closed off 6 cents, or 3 percent, at $1.74 on the Nasdaq market. The stock has fallen more than 62 percent this year, compared with a 53 percent decline by the American Stock Exchange Network Index (AMEX:^NWX - News), an industry proxy.

Sonus President and Chief Executive Hassan Ahmed told Reuters, "The environment out there certainly is still very challenging. Capital spending is very closely tied to near-term business priorities for the carriers."

In the second quarter, including one-time items, Sonus` net loss was $17.8 million, or 9 cents a share, compared with a net loss last year of $51.4 million, or 30 cents a share.

Revenues in the second quarter fell almost 60 percent to $21.3 million from $52.6 million last year. But they rose 15 percent from the previous quarter.

Sonus said in April it expected second-quarter financial results to be flat compared with the first quarter, when it posted a loss before one-time items of $12.8 million, or 7 cents a share, on revenues of $18.5 million.

Analysts were expecting a loss before one-time items of 7 cents a share on revenues of $20.8 million, First Call said.

CLASS ACTION

Sonus, which is based in Westford, Massachusetts, said it had been named as a defendant in a class-action lawsuit that alleges the company made false and misleading statements about its products and business. Sonus said it had not yet filed a response to the complaint, but believed the claims are without merit and it intends to defend itself vigorously.

Sonus also said Thursday it will supply gear for a next-generation Voice Over Internet Protocol network at a unit of Deutsche Telekom AG (XETRATEGn.DE - News; NYSET - News) that will provide large corporations with enhanced voice services. Sonus would only say the contract is a multiyear, multimillion dollar one.

Deutsche Telekom and Qwest combined accounted for about half of Sonus` revenues in the second quarter, officials said.

T-Systems International Selects Sonus Networks to Provide Packet Voice Infrastructure and Services
T-Systems, a Division of the Deutsche Telekom Group, Deploys Complete Sonus Packet Voice Solution; Carrier to Leverage Network to Deliver Enhanced Voice Services to Multi-National Corporations
WESTFORD, Mass.--(BUSINESS WIRE)--July 11, 2002-- T-Systems International GmbH, a division of Deutsche Telekom (NYSE: DT - News), and Sonus Networks (Nasdaq: SONS - News), a leading provider of voice infrastructure solutions for the new public network, today announced that T-Systems has chosen Sonus to build out its next-generation voice over IP (VoIP) network to provide business customers with enhanced voice services. T-Systems will leverage the Sonus-based network for services such as global voice VPN (virtual private network) and sophisticated call center routing facilities, with additional services to follow.

"We required a solution that would offer our key customers - multi-national corporations (MNCs) - the levels of voice quality and reliability that they normally expect from Deutsche Telekom," said Jan Geldmacher, Member of the Board of Management of T-Systems International GmbH, Telecommunications Services. "Moreover, we needed to be able to very rapidly deploy enhanced voice services to address the sophisticated requirements of these MNCs. The solutions Sonus provided addressed these requirements, and we`re very pleased with the early success we have achieved."

Under the terms of a multi-million dollar contract, the two companies are collaborating to build a next-generation network that supports a variety of business applications. As the foundation of the network implementation, T-Systems has deployed a complement of Sonus` award-winning packet voice solutions, including the GSX9000(TM) Open Services Switch, the Insignus(TM) Softswitch and the Sonus Insight(TM) Management System.

"By deploying softswitch technologies, T-Systems can deliver both traditional and enhanced services more easily and rapidly than ever before," said Hassan Ahmed, president and CEO, Sonus Networks. "We are very excited to be working with T-Systems to make the expansion to a next-generation network that allows them to integrate new packet-based enhanced services into their product portfolio."

T-Systems will be rolling out enhanced services applications enabled through Sonus` Open Services Partner Alliance(SM) (OSPA). These packet-based services enable T-Systems to resolve many of the issues normally associated with global corporate networks. Functionality includes the ability to deliver a unique, customer self-provisioning system for the global voice VPN service. This allows T-Systems MNC customers to seamlessly connect and manage multiple international office locations.

To support these initial applications, T-Systems will deploy the Sonus systems in eight countries in Europe and North America, and plans to rapidly expand the network footprint.
