ABSTRACT:
An exchange service starting system subject to a minimum of processing burdens without limiting the scope of exchange services available to subscribers. A number dialed by a subscriber placing a call is analyzed by a number analyzing unit. The result of analysis is stored into a number analysis result memory. Upon receipt of a service start request signal from the subscriber during the call, a signal analyzing unit references the content of the memory. If the memory is found to contain a predetermined specific number, the signal analyzing unit starts a signal output unit to output the service start request signal to a specific exchange. If the memory content is other than the specific number, the signal analyzing unit starts a service request processing unit so that the exchange in question will offer a locally available exchange service.
