PURPOSE:To shorten the period of time until such time as speech dial operation is made available by performing transmission reception of information relating to a speech channel setting between a telephone set and a connector through an optical signal or electric direct coupling. CONSTITUTION:When a telephone set 3 is separated from a connector 2, the communication between the connector 2 and the telephone set 3 is performed by using a radio wave. In this case, in a state that the telephone set 3 is mounted on the connector 2, connector sections 27, 41 for exclusive use of information transmission reception are connected electrically. Thus, the transmission data TD from the connector 2 are directly sent to the data input terminal 37e of the control section 37 of the telephone set 3 via the connector sections 27, 41 for exclusive use of information transmission reception. Similarly the transmission data (td) on the telephone set 3 are directly fed to the data input terminal 25c of the connector 2. Moreover, control sections 25, 37 process the data fed via the connector sections 27, 41 for exclusive use of information transmission reception with priority. |
