MARLBORO, Mass.--(BUSINESS WIRE)--Oct. 7, 2002

Telica(TM), Inc., a leading provider of softswitch-based voice and data infrastructure products for today's evolving telecommunications network, announces that KMC Telecom(TM) has completed the deployment of Telica's Plexus(TM) 9000 in a ten million dollar, multi-city contract for its voice and data switching requirements. KMC Telecom, a provider of fiber-based integrated communications, offers a full range of advanced voice, data and Internet infrastructure services. KMC is currently one of the largest privately held nationwide telecommunications companies, serving over 140 markets across the USA.

KMC utilizes Telica's Plexus 9000s to provide dialup Internet services today and to potentially offer a range of packet services in the future. The Plexus 9000s have been deployed in 13 Tier One cities and are carrying over one billion minutes of use per month. KMC purchased its initial Plexus 9000 in late 2000 and selected Telica for its expanded network requirements due to the economic efficiencies, superior scalability and density that the Plexus 9000 offers.

"We looked at all of the available switching platforms and selected Telica for its flexibility, economics and scalability," said Roscoe Young, Co-CEO, and COO of KMC Telecom. "The adoption of the Plexus 9000 into our network has enabled KMC to offer a greater range of services to our customers, and to do so with revolutionary economics. Having Telica as a strategic partner has already paid dividends for KMC and has positioned us for even greater success in the future as we take further advantage of cutting edge technology."

Telica's solution offers integration into legacy networks, utilizes the advantages of next generation packet switching technology and meets the economic objectives of carriers for both local and long distance, residential and business services. As carriers strategically transform their networks to offer next generation services and meet the demands of today's evolving telecommunications needs, deploying the Plexus 9000 enables them to continue to provide efficient voice and data services.

"Despite a challenging market, KMC continues to execute and remain a forward thinking company with a cutting edge network," said John St. Amand, Telica's president and CEO. "Telica has been working with KMC from our beginning and the experience we've garnered in such a large scale deployment is invaluable. We are pleased to be associated with KMC and are proud that they are realizing the economic efficiencies the Plexus 9000 can bring to a network."

"Innovative carriers like KMC in partnership with leading edge suppliers like Telica are putting increasing pressure on more traditional networks operators to lower costs and bring new services to market," said Steven D. Levy, Managing Director at Lehman Brothers.

Telica's Plexus 9000 is a carrier-grade switch that includes all the elements of a softswitch-based solution, media gateway, media gateway controller, and signaling gateway, to provide Class 4/5 switching for the PSTN as well as ATM and IP networks. These various softswitch components may be deployed in either a distributed, centralized or integrated configuration to meet a wide range of network requirements. A single Plexus 9000 shelf supports up to 137,088 ports for TDM applications and up to 24,192 simultaneous calls for voice over packet applications independent of IP or ATM packetization. The unparalleled scalability and architectural deployment options provide the highest level of flexibility for service providers.
