ABSTRACT:
When a no-communication state is detected for a predetermined time of time during communication in response to an interrupt designation to or from an apparatus on the other end of the line, an operation of a time monitoring timer for terminating the communication is interrupted. The time monitoring timer is restarted in response to a restart designation. Therefore, communication can be continued without interrupting an interrupt/restart service provided by, e.g., an ISDN due to a time-out error. When a trouble which disables communication occurs during communication, an interrupt service is requested to a network. When the trouble which disables communication is recovered, a restart service can be requested to the network. In this case, communication can be normally restarted without being accidentally terminated intermediately.
