Xtend Networks, MasTec Partner on Deployment of Commercial Services Solutions for Cable

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, and MasTec (NYSE:MTZ), a leading end-to-end voice, video, data and energy infrastructure solution provider, today announced a strategic alliance designed to speed the deployment of commercial services solutions to cable system operators.

Xtend and MasTec will jointly market a comprehensive package for the cable industry, combining Xtend's solutions for the delivery of symmetrical, voicegrade T1 (1.544 megabits per second) and 3 GHZ services with MasTec's expertise in hybrid fiber-coaxial (HFC) network architectures.

Xtend's T1 solution is in trials with cable operators in major 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 Xtend becoming an approved vendor of Cox Communications.

"As cable system operators increasingly expand into the deployment of symmetrical commercial services over existing networks, they are seeking the simplest and most reliable implementation of the best possible solutions from proven vendors," said Bill Keating, CEO of Xtend Networks. "The combination of MasTec's infrastructure expertise and Xtend's innovative T1 and 3GHz solutions will give cable operators the capacity and the levels of service they need to win business customers from incumbent providers."
