Abstract
An Asynchronous Transfer Mode (ATM) network comprising a plurality of ATM switches may be arranged so that it receives calls from Synchronous Transfer Mode (STM) switches that employ in-band signaling by first converting in-band signals received from an STM switch to an out-of-band signaling message and then transmitting the message to the ATM switch that will route the associated call toward its destination. At an interface which interfaces the ATM switch with the out-of-band signaling network, the contents of the received message are converted to a form suitable for presentation to the ATM switch. For example, the identity of the trunk over which the call will be routed from the STM switch to the ATM switch is converted to a virtual channel identifier.
