The Society of Cable Telecommunications Engineers and the European Telecommunications Standards Institute recently released specifications defining an advanced IP architecture for cable systems called IPCablecom, an evolution of CableLabs' PacketCable initiative.
The IPCablecom specs define an end-to-end system for the delivery of communications services, including IP telephony to the homes of cable customers. The standards groups have released a set of 12 IPCablecom documents that define the fundamental requirements for signaling, QoS, codecs, client provisioning, billing event message collection, PSTN interconnection and security interfaces necessary to implement a single-zone IPCablecom system for residential IP voice services.
SCTE said it has approved the full set of IPCablecom documents as a standard and that standard has become the purchase specification for cable operators throughout North and South America. The ITU-T approved the majority of the documents last March for worldwide use. ETSI has accepted and is continuing to develop the suite as a set of technical specifications and is using the ITU-T J.160 Recommendation as the framework to add European-specific requirements.
