ABSTRACT:
An Asynchronous Transfer Mode (ATM) network comprising a plurality of ATM switches may be arranged so that it may receive for routing telephone calls originating at Synchronous Transfer Mode (STM) switches. This may be done in the ATM network by accumulating voice signals as they are received from a STM switch and forming an ATM data-cell payload when the accumulation includes a predetermined number of the voice signals, e.g., 48 voice signals. The payload and a header, including a virtual channel identifier determined as a function of the identity of the STM trunk over which the voice signals were received, may then be supplied to an associated ATM switch for routing to an intended destination.
