PURPOSE:To reduce the function of a terminal station to realize simple configuration and to reduce energy consumption and to improve reliability by setting a return line in the same terminal station when a call originated from a terminal is decided as connection within the same terminal station. CONSTITUTION:A dial signal from the terminal to be held in a terminal station 2 is transmitted through a radio line to a base station 1 and a dial signal analyzing means 12 of the base station 1 identifies the terminal to be connected from the received dial signal while referring the contents of a terminal installation information. When the received dial signal is judged as the connection within the same terminal station 2, the incoming terminal of a control means 13 makes off-hook to send out a control signal to a control means 22 of the terminal station 2 when a call is started, cutting off the radio line, designates the terminal to write sound data into a storing means 21 and the terminal to transmit the sound data read out from the storing means 21, constitutes the loop back line at the terminal station 2 and executes the call. Thus, the configuration of the terminal station 2 can be simplified. |
