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.
Claims8
A communication apparatus comprising:
- sending means for sending address data of a destination with or without sub-address data to a digital line, the destination having at least one communication terminal capable of being specified, and the sub-address data corresponding to a specified one of the at least one communication terminal of the destination so as to communicate with the specified communication terminal;
- and
- detecting means for detecting a response from the digital line when said sending means sends the address data with the sub-address data to the digital line,
- wherein said sending means resends the address data of the destination without the sub-address data on the basis of a detection of said detecting means.
A communication method comprising:
- sending address data of a destination with or without sub-address data to a digital line, the destination having at least one communication terminal capable of being specified, and the sub-address data corresponding to a specified one of the at least one communication terminal of the destination so as to communicate with the specified communication terminal;
- and
- detecting a response from the digital line when said sending step sends the address data with the sub-address data to the digital line,
- wherein said sending step automatically resends the address data of the destination without the sub-address data on the basis of a detection of said detecting step.
