1. A control method of a terminal for an integrated services digital network, comprising the steps of:
- generating an instruction to restart a call which has been interrupted by another terminal having a voice attribution by a manual operation;
transmitting to the digital network a first message to request a restart of the interrupted call in response to the instruction;
receiving a second message indicating the restart of the interrupted call from the digital network; and
perfoming a G3 image communication in the form of digital voice data through the digital network in response to the second message.

Abstract
A transferring method from an ISDN telephone to an ISDN data terminal comprises the steps of: transmitting a message to request a temporary interruption of a call to the ISDN from the call received ISDN telephone; transmitting a message to request a start of the interruption call to the ISDN from the ISDN data terminal connected to the same bus, as that of the ISDN telephone; and executing a data communication such as a G3 facsimile communication by the ISDN data terminal.
