PURPOSE:To attain the conversion of a dial signal inexpensively by allowing a radio line controller to convert a dial control data sent from a radio telephone set after the end of a call connection via a radio connection equipment into a kind of dial signal set corresponding to each of radio telephone set and sending the result to an exchange. CONSTITUTION:When the call connection is finished, a portable telephone set RTEL 1 sends a dial control data. A pushbutton is provided to the RTEL 1 and the dial control data is generated by the operation of the pushbutton. The dial control data is sent in radio through a talking channel between the RTEL 1 and the radio connection equipment CE2, and sent through a wired connection line L1 between the CE2 and the radio line controller RCU3 and received by the RCU3. The RCU 3 converts the received dial control data into the dial signal of a kind set corresponding to the RTEL 1 and sends the signal to a PBX 4 via an extension L2. Thus, it is not required to provide the hardware for dial signal conversion for each CE and then the economical system is obtained. |
