ABSTRACT:
In a single line communication apparatus for both telephone and data (e.g., facsimile), the communication line is switched from a telephone to a data communication unit when an incoming data call is received in response to an indication for data communication from the telephone. The communication line is monitored to detect the occurrence of a non-aural terminal calling tone (CNG) within a predetermined time period. Upon detection of the CNG tone within the predetermined time period, a non-aural called party discrimination signal (CED) is transmitted to indicate the start of a data communication.
