Abstract

An improvement in providing simultaneous voice and data communication is achieved by provisioning within the public switched telephone network one or more simultaneous voice/data (SVD) modems that a) can communicate with SVD modems of the network users over a single 'plain old telephone service' (POTS) connection, and b) can separate, and deliver to different destinations the voice and data channels received from an SVD modem. The SVD modems in the network can also combine voice and data traffic from separate sources for transmission together over a single POTS connection to a user's SVD modem. In one embodiment of the invention, an SVD modem pool is provided by an inter-exchange carrier. The voice and data channels of an SVD call are separated at the network side of the SVD modem pool, so that they may be routed to different destinations. The voice channel of the call a) may be routed in the usual manner to a voiceband destination device or b) it may be routed to an SVD modem pool for possible combination with a data channel for delivery to an end-point subscriber who has an SVD modem. The data channel or the call may be routed over the packet network to a) a conventional data device or b) an SVD modem pool for possible combination with a voice channel for delivery to the end-point subscriber who has an SVD modem.
