ABSTRACT:
A central office of a public switched telephone network has a modem pool that includes both simultaneous voice and data (SVD) capable modems and standard, e.g., CCITT V.32 compatible, modems. A user with an SVD modem, i.e., an SVD user, establishes an SVD link with the SVD modem of the central office. These SVD modems exchange SVD signals that include voice and data. The SVD modem of the central office separates the voice and data portions of the SVD signal for separate transmission to different parties. The voice portion of the SVD signal receives standard voice-call handling from the central office for transmission to the party that is a part of the voice call. The data portion of the SVD signal is routed through the standard modem of the central office for transmission to the party that is a part of the data call. As a result, neither of these remote parties is required to have an SVD capable modem--yet the SVD user has both a voice connection and a data connection over a single "tip/ring" type telephone line.
