CableLabs Gearing up for PacketCable Compliance Testing
CableLabs reported that its has successfully completed a second round of interoperability testing based on the interim specs it released last year. The event was primarily focused on firming up the proper test environment and initial compliance test plans (just released in draft form) that will be used to gauge the compliance of products with the specifications. Fifteen vendors participated in the latest event, testing a variety of equipment for interoperability according to both PacketCable and DOCSIS (Data over Cable Service Interface Specification) specifications. The group also just released several initial compliance test plans to the CableLabs member companies, which establish detailed test cases for 7 of 11 interim PacketCable specifications. The remaining test plans are expected to be released over the next few months, with the full set slated for availability by the end of the year.

The organization is also gearing up for formal compliance testing (certification) based on the PacketCable specifications, with initial compliance testing targeted at PacketCable access components such as embedded multi-media terminal adapters (MTA), cable modem termination systems (CMTS) and call management servers (CMS). Future waves of testing are expected to expand to provide coverage for PacketCable-specific elements in the backbone portion of an architecture.

The interim PacketCable specs provide the fundamental requirements for call signaling, QoS, media stream, client provisioning, billing event message collection, PSTN interconnection, and security interfaces necessary to implement a PacketCable solution for residential voice services. The specs define the implementation of residential services as a set of CPE that can be controlled by a single call management server or cluster of servers on a network (between tens of thousands and hundreds of thousands of subscribers). CableLabs also plans to further develop the specs to include the protocol technology necessary to provide interoperability across service provider boundaries, and to define additional feature capabilities, such as PBX extension and multimedia conferencing.

The next testing cycle is scheduled for later this month.

PacketCable is a CableLabs led initiative aimed at developing interoperable interface specifications for delivering real-time multimedia services over two-way cable plant. The initiative is focused on using cable modem infrastructure running IP technology to provide an array of multimedia services including IP telephony, multimedia conferencing, telecommuter services, as well as other integrated multimedia applications.
