Abstract
A communication system, and an apparatus therefor, are used in combination with an integrated service digital network. The proposed system, and the apparatus, can achieve a change of service from an equipment to another, for example from a telephone unit to a facsimile unit, both connected to the same telephone line, without disconnecting a call made through the telephone line. For this purpose, the proposed system or apparatus has a discriminating unit for identifying a request for communication released from another unit connected to the same telephone, and a communication control unit for automatically communicating with a destination unit with which said other unit has been communicating through said telephone line.
