Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 122 words
A data communication equipment for communication via a line, said equipment comprising: data communication means for communicating data and for receiving data; speech communication means for communicating speech; selection means for selecting said data communication means or said speech communication means to set said data communication equipment in a data communication mode or a speech communication mode; and output means for outputting a sound on the basis of a sound signal received through the line when said equipment is in the data communication mode which has been set by said selection means, said data communication equipment further comprising detection means for detecting a procedure signal for data communication, wherein said output means is stopped when said detection means detects the procedure signal.
Claim 2
Dependent Claim 122 words
A data communication equipment for communication via a line, said equipment comprising: data communication means for communicating data and for receiving data; speech communication means for communicating speech; selection means for selecting said data communication means or said speech communication means to set said data communication equipment in a data communication mode or a speech communication mode; and output means for outputting a sound on the basis of a sound signal received through the line when said equipment is in the data communication mode which has been set by said selection means, said data communication equipment further comprising detection means for detecting a procedure signal for data communication, wherein said output means is stopped when said detection means detects the procedure signal.
Claim 3
Dependent Claim 35 words
A data communication equipment according to claim 1, further comprising means for sending a procedure signal for data communication, wherein said output means is disconnected from the line during the transmission of the procedure signal.
