Abstract

See full text

In conjunction with a data communication network carrying multiple telephony signals and allowing for connection of telephone sets, a system and method in which two external feeders connect to the data network at two distinct points via two distinct devices. The data network can be based on dedicated wiring or can use existing in-premises medium such as telephone, powerlines or CATV wiring. In the latter case, the wiring can still carry the original service for which it was installed. The external telephone connections can be based on the traditional PSTN, CATV network, cellular telephone network or any other telephone service provider network, using specific adapter for any medium used. In the case of connection to a POTS telephone signal, VoIP gateway (or any other converter) is required.
