<p>A request received via the interface specifying a service requested by the terminal, is responded to with an acknowledgement indicating if the service requested is supported or not by the terminal. The acknowledgement may indicate an alternative service if the requested service is not supported. Typically, an inter-working unit (1) converts a data stream from an ATM terminal into a protocol suited to the ISDN terminal (2) and vice versa. An Independent claim is included for a communication network.</p> |
