Abstract
A communication apparatus utilizes a distinctive ringing pattern service provided by a switching network for switching speech communication to and from data communication and for telling who is to answer an incoming call. In the apparatus, communication is switched between speech communication, including voice answering communication, and data communication, including facsimile data communication, according to an intermittent pattern of a call signal from a switching network. Data corresponding to the intermittent pattern of a call signal is transmitted, data from a calling party side is recorded and character information corresponding to the intermittent pattern of a call signal is displayed.
