Summary for IPCablecom The initial focus has been on Vo. IP For a single zone, a set of interfaces has been approved by SCTE, ETSI and ITU-T SG 9 They cover signaling, Qo. S, codecs, billing, provisioning, security They cover POTS capability Local Exchange interfacing is the subject of regional work (using GR 303 for North America, V 5. 2 in ETSI) For interdomain Vo. IP over cable networks, Qo. S is defined Later there will be enhancements for multimedia Telecommuting, videoconferencing, interactive gaming, . . .
