Xtend Networks to Demonstrate T1 and its Bandwidth Expansion Solutions at Cablelabs(R) Summer Conference

ATLANTA, Aug. 12 /PRNewswire-FirstCall/ -- Xtend Networks(TM), a Vyyo(R) company (NASDAQ:VYYO) that provides advanced broadband solutions for the cable TV industry, will demonstrate both its T1-over-coax and its in-band bandwidth expansion solutions at the CableLabs(R) Summer Conference August 14-17 in Keystone, CO.

In its booth at the conference, Xtend will show the ability of its DOCSIS(R) based XMTS to deliver symmetrical 1.544 megabits per second telecom-quality services over hybrid fiber-coaxial (HFC) networks. Xtend will also feature Xtend's bandwidth expansion solutions that are designed to expand the usable downstream bandwidth by up to two times and increase up to tenfold the upstream bandwidth of typical hybrid fiber-coaxial (HFC) network architectures. Xtend's T1 products have received certification from the Administrative Council for Terminal Attachment (ACTA) for compliance with the Telecommunications Industry Association's TIA-968-A-3 standards for the connection of terminal equipment to the telephone network.

Xtend Networks' solutions are currently being trialed by cable operators in multiple markets. Xtend's solutions for the delivery of expanded, DOCSIS(R)-compatible, RF (radio frequency) bandwidth on the existing coaxial plant and for delivery of T1 voice and data services over hybrid fiber coax networks have led to its becoming an approved vendor of Cox Communications.

"Cable system operators continue to seek new ways to maximize the advantage of their existing HFC plant," said Al Johnson, vice president, technology and advanced architectures for Xtend. "The ability to provide true T1 services and to dramatically increase upstream and downstream bandwidth offer new opportunities for our customers to generate greater returns on the industry's $100 billion HFC investment."
