Abstract
For use at a subscriber site with a subscriber line, for simultaneously sending a telephone call from a PSTN compatible telephone terminal on the subscriber site, and IP packets from a first computer, over the subscriber line, the adaptor has a converter for converting signals from the telephone terminal into IP packets, and a multiplexer, for sending simultaneously the IP packets representing the telephone call and those from the computer, along the subscriber line. The adaptor is also arranged to handle calls without conversion to IP packets, when the subscriber telephone line is not used for carrying IP packets. Using one subscriber line, all phones in a household can remain operational, to make and receive calls, while one or more PCs are concurrently accessing online services, without needing a second line, or special equipment to increase the bandwidth transmissible over the line.
