摘要

Cable modems are spreading as one of the high-speed data services for home use. In the United States, trials are progressing to provide telephony service using Voice over Internet Protocol(VoIP) technologies over this high-speed data service. CableLabs~R in the United States has defined a standard called PacketCable~(TM) and started certification tests this year in order to maintain interoperability of telephony services among vendors. Cable operators in the United States are searching for a solution for telephony services before the standards are finalized.Toshiba has been participating in several trials since January 2000, and has developed the PCX3000SH VOIP cable modem to obtain know-how of VoIP technologies from these trials. The PCX3000SH was demonstrated at the Western Show in November 2000.
