Xtend Networks Announces DS3 Interface, Higher Density XMTS Products to Simplify Delivery of T1 Services Over HFC Networks

SAN ANTONIO, June 15 /PRNewswire-FirstCall/ -- Xtend Networks(TM), a Vyyo(R) company (NASDAQ:VYYO) that provides advanced broadband solutions for the cable TV industry, today announced the availability of a DS3 interface and the availability of higher density XMTS Access Concentrator(TM) products to simplify the delivery of symmetrical, voice-grade T1 (1.544 megabits per second) services over hybrid fiber-coaxial (HFC) network architectures.

The interface enables the use of a single DS3 line, rather than 24 individual DS1 lines, to provide the T1 links between the XMTS at the cable system headend and their existing SONET backbones. Utilizing Xtend's interface will allow operators deploying the XMTS to deliver a total data rate of 44.736 Mbps over a single DS3 line with reduced complexity and costs, as well as an increased ability to seamlessly expand T1 services in the future.

In conjunction with the DS3 availability, Xtend has expanded its XMTS product family to maximize capacity while optimizing space in headend environments. Products include:

-- The XMTS-28, supporting 24 T1 links and a single DS3 port;
-- The XMTS-48, supporting 48 T1 ports, and featuring 12 upstream and
eight downstream RF ports; and
-- The XMTS-56, supporting two DS3 ports, and featuring 12 upstream and
eight downstream RF ports.

"The reception we have received from cable system operators indicates that there is a large and growing market for our T1 solution for the delivery of commercial services and cellular traffic backhauls," said Bill Keating, CEO of Xtend Networks. "While we already provide optimal performance for the industry, it is important that we also dedicate resources to making implementation of our solution as simple and cost-effective as possible for our customers."

Xtend's carrier-class T1 technology combines the XMTS with Xtend's V3xx family of T1 modems to provide an ANSI T1-compliant, low jitter, low latency solution that utilizes existing HFC infrastructure and operations support systems.

To speed revenue from the T1 solution for cable system operators, Xtend has created a complete value chain for the delivery of backhaul traffic for cellular services providers. The value chain capitalizes on alliances with GeoResults for market data, Mastec and GTS for equipment installation and Paradigm Telecommunications for contracts with cellular carriers, providing a turnkey solution for the cable industry.

Xtend's T1 solution currently is being trialed by cable operators in multiple markets in the southeastern United States. Xtend's solution for the delivery of 3 GHz of bandwidth over 860 MHz coaxial plant has already led to its becoming an approved vendor of Cox Communications.

Safe Harbor Statement

Statements made in this press release relating to the future, including those related to (1) the potential for the DS3 interface to simplify the delivery of services, (2) whether the interface will enable operators to use a single DS3 line to provide applicable links, (3) the potential for the interface to allow operators to deliver a total data rate of 44.736 Mbps over a single DS3 line with reduced complexity and costs, as well as an increased ability to seamlessly expand T1 services in the future and (4) the potential for Xtend's systems to enable the cable industry to economically enhance their networks, are forward-looking statements within the meaning of the "safe harbor" provisions of the Private Securities Litigation Reform Act of 1995. Because these forward-looking statements involve risks and uncertainties, there are important factors that could cause our actual results to differ materially from those in the forward-looking statements. These factors include, without limitation, the performance characteristics, reliability and consistent availability of the DS3 interface; the current limited visibility available in the telecommunications and broadband access equipment markets; whether Xtend will be able to move from the development stage to deployment and establish commercial relationships with the cable system operators; whether the cable industry will be willing and able to substantially increase the available bandwidth on their networks and do so using Xtend's alternative technology solution; and other risks set forth in Vyyo's annual report on Form 10-K for the year ended December 31, 2004, its quarterly report on Form 10-Q for the three months ended March 31, 2005 and in other periodic reports filed by Vyyo with the Securities and Exchange Commission from time to time.
