Abstract
Abstract A communicating apparatus connected to an extension line of a private branch exchange (PBX) network comprises: a judging unit to judge whether a call was performed to an external line of the PBX network or a call was executed to an extension terminal; and a transmission unit to transmit terminal information according to the result of the judgment by the judging unit through the extension line. The terminal information includes a calling party number in an SETUP command. The transmission unit transmits the terminal information in a G4 facsimile procedure.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
103 words
A communication apparatus connected to an extension line of a private network which is connected in turn to an external line of a public network, comprising: input means for judging whether the communication request is sent to an extension terminal of the private network or to the external line through the private network; selecting means for selecting either terminal name information for the private network or terminal name information for the public network in accordance with a judgment by said input means; and transmitting means for transmitting to the extension line a protocol signal including terminal name information selected by said selecting means.
Claim 2
Dependent Claim
103 words
A communication apparatus connected to an extension line of a private network which is connected in turn to an external line of a public network, comprising: input means for judging whether the communication request is sent to an extension terminal of the private network or to the external line through the private network; selecting means for selecting either terminal name information for the private network or terminal name information for the public network in accordance with a judgment by said input means; and transmitting means for transmitting to the extension line a protocol signal including terminal name information selected by said selecting means.
Claim 3
Dependent Claim
19 words
