Abstract
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.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
114 words
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.
Claim 2
Dependent Claim
114 words
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.
Claim 3
Dependent Claim
14 words
A communication apparatus according to claim 1, further comprising a handset for speech communication.
Claim 4
Dependent Claim
19 words
A communication apparatus according to claim 1, wherein the digital line is connected to an integrated services digital network.
Claim 5
Dependent Claim
25 words
An apparatus according to claim 1, wherein the response includes a negative command to not resend the address data when the specified communication terminal responds.
Claim 6
Dependent Claim
109 words
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.
Claim 7
Dependent Claim
109 words
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.
Claim 8
Dependent Claim
18 words
A communication method according to claim 5, further comprising a step of using a handset for speech communication.
Claim 9
Dependent Claim
19 words
A communication method according to claim 5, wherein the digital line is connected to an integrated services digital network.
