11 Other Devices Also Certified for DOCSIS® 3.0, 2.0 Networks

Louisville, Colorado, April 13, 2009—CableLabs® has announced that embedded digital voice adaptors (E-DVAs) from Ambit and Thomson have achieved certified status for PacketCable™ 2.0, a set of specifications aimed at accelerating the convergence of digital voice and multimedia services in consumers' homes. The announcement follows a recently completed Certification Wave 65, the results of which are available at www.cablelabs.com/certqual/lists/.

The Ambit and Thomson E-DVAs represent the first PacketCable 2.0 equipment to successfully pass through certification testing at CableLabs. The PacketCable 2.0 core service architecture is based on common standards technologies such as the IP Multimedia System (IMS) and the Session Initiation Protocol (SIP).

"This success marks a milestone for our industry's efforts to offer consumers new services," said Tony Werner, CTO and Executive Vice President at Comcast. "I expect that we will see more advances in multimedia offerings as our industry continues to deliver more choice and convenience to our customers."

"The PacketCable 2.0 architecture represents a major technical advance for the cable industry, providing a flexible platform for service innovation across a wide variety of devices. We congratulate Ambit and Thomson on this milestone accomplishment and look forward to continued momentum for the project," said Ed Miller, Senior Vice President of Broadband Network Services at CableLabs.

In addition to the two E-DVAs, Ambit and Thomson each achieved certification for a PacketCable 1.5 embedded multimedia terminal adapter (E-MTA) that implements DOCSIS 3.0. There also were seven DOCSIS® 3.0 cable modems certified from the following manufacturers: Two from Ambit, two from Cisco, and one each from Netgear, SMC, and Thomson. Two DOCSIS 2.0 cable modems were certified, one each from Cisco and Motorola.

CableLabs certified® means that the device has passed a series of tests for compliance with the indicated version of the CableLabs specification and has thus demonstrated interoperable functionality with any additional "CableLabs certified/qualified" device. Many of these devices provide additional functions or are designed to comply with other specifications, in each case tailored by the manufacturer to meet the growing needs of consumers or cable operators in an evolving communication/entertainment sector.

While CableLabs encourages such innovation and diversity, the phrase CableLabs certified/qualified should not be understood as an endorsement of these additional attributes (or that the product is certified to other specifications or versions), which are solely the responsibility of the company making the additional claims.
