PURPOSE:To discriminate easily that a radio equipment is connected to the communication channel of own station, and to perform the effective operation of channels, by displaying that a terminal connected to the channel by the request of connection is under communicating state. CONSTITUTION:The receiver 2 of a terminal station of a multichannel access system for mobile radio communication receives a control channel signal and a synchronism detecting circuit 3 performs the bit synchronization of a down control signal. Then, a control comparing circuit 4 makes bit-by-bit comparisons with syndrome codes, command information, etc., of its group stored in the storage circuit 5 of the terminal station, and the results are verified; and when the result is coincident with that of own station is found, a channel specifying circuit 7 sends out a specified channel No to a channel frequency oscillator 8. Further, a signal for the channel specification is outputted to an AND circuit 9 and when a signal after channel switching is inputted from the oscillator 8 to the circuit 9, a service state is displayed on a display part 11. Then, the effective operation of channels is realized. |
