Vyyo Selected by Cox Communications for Deployment of T1 Over HFC Solution for Business Services in Oklahoma

Vyyo's T1 Solution helps leverage existing HFC plant investment; offers cost-efficient means for generating high-margin revenue

NORCROSS, Ga., June 20 /PRNewswire-FirstCall/ -- Vyyo Inc. (NASDAQ:VYYO), a supplier of broadband access equipment for cable system operators, announced today that Cox Communications, the country's third-largest cable system operator, has deployed the Vyyo T1 over HFC solution for the delivery of Business Services in Oklahoma.

Cox deployed Vyyo XMTS V3000 headend modular systems and V311 modems for the delivery of telecom-quality T1 services over the existing Cox Oklahoma HFC infrastructure. The Vyyo "T1-in-a-Box" solution offers cable system operators a simple, cost-effective way to generate a stable, high-margin revenue stream through the deployment of business services.

"Cox's ability to leverage our existing hybrid fiber and coax plant investments is key to our success in serving commercial customers," said Allen Roberts, vice president of business services for Cox Oklahoma. "Vyyo's solution helps us to meet the needs of business customers using the HFC network and to prioritize the use of our fiber solutions."

"The market opportunity for cable system operators to offer commercial services has been estimated at up to $130 billion per year," said Wayne Davis, chief executive officer of Vyyo. "Tremendous value and revenue potential exists for operators, like Cox, that roll out Vyyo's easily-deployed, highly-reliable T1 over HFC solution."

The Vyyo T1 solution also allows the deployment of T1 services following the same model that has served the cable industry's high-speed data rollout so well: a headend-based broadband hub supports T1 traffic over existing HFC plant to and from T1 modems at customer premises. The modem uses the same drop as existing video or high-speed data service. The Vyyo solution uses an enhanced version of the DOCSIS(R) protocol to provide the low latency and low jitter required for reliable T1 service.

Vyyo estimates that T1 service can generate average monthly revenue per unit (ARPU) of up to $400, rather than the $30-$40 ARPU of cable modem service, with service agreements that typically extend 36 months. GeoResults, a telecommunications database and marketing firm, also estimates that the cellular backhaul opportunity for cable will reach $42 billion by 2010.
