ABSTRACT:
A communication apparatus sends the address data of a destination, with or without sub-address data, to a digital line. The destination itself has at least one communication terminal capable of being specified, and the sub-address data corresponds to a specified one of this at least one communication terminal of the destination. When the communication apparatus sends the address data with the sub-address data to the digital line, the intention is to communicate with the specified communication terminal. The communication apparatus detects a response received through the digital line when the address data with the sub-address data has been sent thereto, and resends the address data without the sub-address data on the basis of the detection.
