““IPCablecom”IPCablecom”

IPCablecom refers to standards for IP cable communications

IPCablecom defines architecture and interface specs.

IPCablecom builds on SG9’s J.83/J.112 cable modem transport (“DOCSIS/ EuroDOCSIS 1.1”, etc.)

IPCablecom initial market driver is IP telephony

Summary for Summary for IPCablecomIPCablecomThe initial focus has been on VoIP

For a single zone, a set of interfaces has been approved by SCTE, ETSI and ITU-T SG9

They cover signaling, QoS, codecs, billing, provisioning, securityThey cover POTS capability Local Exchange interfacing is the subject of regional work (using

GR303 for North America, V5.2 in ETSI)For interdomain VoIP over cable networks, QoS is defined

Later there will be enhancements for multimediaTelecommuting, videoconferencing, interactive gaming,...
