Louisville, Colorado, April 29, 2004—Less than a year after issuing the PacketCable™ Multimedia specification in mid-2003, CableLabs® held a successful PCMM interoperability event at its new facilities here at the end of Q1 �04. Eight supplying companies participated in the three-day non-certification event.

The Multimedia specification defines how cable operators may deliver enhanced multimedia services over DOCSIS® (Data over Cable Service Interface Specification) 1.1 or 2.0 networks with guaranteed bandwidth via Quality of Service (QoS). The PCMM effort will enable a wide variety of graphically-rich services such as video communications and interactive games to be delivered via cable�s Internet Protocol (IP)-based network.

The companies that participated in the interoperability event were cable modem termination system makers Arris, Cisco Systems and Motorola; policy server firms Camiant, Telcordia and CableMatrix; and PCMM-defined application managers Ellacoya, Syndeo and Telcordia.

�These interoperability events are very helpful to our efforts,� said Glenn Russell, Director, Multimedia Applications in the CableLabs PacketCable initiative. �We saw a wide range of product implementations during the event, Russell added. �It is very evident that the manufacturing community has made considerable progress.�

CableLabs-based interoperability events provide open forums for manufacturers to: (1) work together to achieve interoperability, (2) accelerate product development, and (3) identify new technical requirements needed in the specifications.

�PacketCable Multimedia enables us to add new real-time services in a scalable fashion on top of our DOCSIS and PacketCable platforms,� said Steve Craddock, Executive Vice President of Comcast New Media. �It�s a lightweight framework that provides us with enormous capabilities for service management.�
