New specs for advanced IP architecture
CableLabs and two standards groups have developed a set of specifications that define an advanced IP architecture.
The specifications, called IPCablecom, define a complete system for delivering communications services, including telephony, to residential cable customers, CableLabs reports.
The system is based on IP and advanced packet transmission. The specifications comprise 12 documents defining the "fundamental requirements for signaling, quality of service, codecs, client provisioning, billing event message collection, PSTN interconnection and security interfaces necessary to implement a single-zone IPCablecom solution for residential Internet protocol voice services," CableLabs says in a statement, adding that a zone is expected to support between tens of thousands to hundreds of thousands subscribers.
SCTE has approved the set of IPCablecom documents and ITU-T approved the majority of the documents for worldwide use. ETSI has accepted and is continuing to develop the suite as a set of technical specifications that use the ITU-T J.160 Recommendation as a framework for European requirements.
