Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
179 words
A data communication apparatus comprising: memory means capable of storing telephone number data and also information representing data communication permissible telephone number data; dialing means for executing a dialing operation in accordance with the telephone number data stored in said memory means; receiving means for receiving telephone number data of a partner station sent from the partner station; instructing means for instructing a dialing operation based on the telephone number data stored in the memory means; and control means for controlling the dialing operation in response to an instruction of said instruction means, and for, upon reception of a call, comparing telephone number data of a partner station received by said receiving means with the telephone number data stored in the memory means to control data communication in accordance with a comparison result; wherein when a dialing operation is executed by an instruction of said instruction means, said control means judges whether or not the information is stored in said memory means, and if it is judged that the information is stored, said control means prohibits the dialing operation.
