Abstract
A simultaneous voice and data (SVD) modem includes two analog ports and a data terminal port. Both of these analog ports are capable of transmitting telephone numbers and are coupled to a switching system like a private branch exchange (PBX). The data terminal port is coupled to a data terminal of an SVD user. In one embodiment of the invention, the SVD user, the calling party, sends at least one command to the SVD modem, via the data terminal port. In response, the SVD modem separately transmits, to the PBX, the calling party number from one of the analog ports and the called party number from the remaining analog port. The SVD modem then subsequently communicates any voice signals received on one of the analog ports to the other analog port. This allows a voice call to be switched through the SVD modem, yet requires no modification to the PBX.
