@Home Network to Integrate Bay Networks DOCSIS-based Product; Companies build on experience with proprietary technology to ready standards-based broadband services.

SANTA CLARA, Calif.--(BUSINESS WIRE)--June 23, 1998--Bay Networks(R), Inc. (NYSE:BAY) and @Home Network (NASDAQ:ATHM) today announced that @Home is testing the Bay Networks Versalar Cable Modem Termination System (CMTS) 1000. Testing at @Home's labs is for the deployment of services based on the Data-Over-Cable System Interface Specification (DOCSIS) driven by CableLabs of Louisville, Colorado, the research and development arm of the North and South American cable industries. The Versalar CMTS 1000 is a DOCSIS headend controller that terminates broadband cable connections to deliver standards-based high speed interactive data services such as Internet access, multimedia, voice and video over the cable infrastructure.

@Home is testing the Versalar CMTS to integrate into the @Home modem provisioning systems. In addition, as part of this testing process @Home will integrate Bay Networks' MCNS/CMTS MIB variables into the @Home Network Management System. With this testing and integration, Multiple Systems Operators (MSO's) are assured that DOCSIS-based Bay networks products, integrated in to the @Home systems, can be used reliably and interoperate seamlessly in their data ready cable systems. The companies will leverage extensive experience in deploying Bay Networks current generation of LANcity cable modems with @Home affiliates including Cox Communications, Marcus Cable, Rogers, and TCI.

"Integration with @Home provides us with access to a significant subscriber base today and in the future. The mass deployment of DOCSIS-based broadband services brings us one step closer to widespread acceptance of this technology, and the rigorous testing that our products will undergo in @Home's labs will ensure the best quality services for @Home affiliates," said Karl May, vice president and general manager of the Bay Networks Broadband Technology Division.

The DOCSIS interoperability program is an open effort to design and to specify interconnection points for cable modems that has been actively supported by @Home and Bay Networks since its inception. This endeavor is driven by CableLabs of Louisville, Colorado, the research and development arm of the Multimedia Cable Networks System, LTD (MCNS). MCNS is a consortium of cable television system operators representing the North and South American continents.

"@Home is committed to providing our growing consortium of cable partners with standards-based solutions that will enable the wide-spread deployment of high-speed data services," said Dean A. Gilbert, senior vice president and general manager of @Home Network. "Once Bay's DOCSIS-based products have been certified by @Home, our partners can rest assured that these products can be reliably implemented in their advanced HFC networks."
