PURPOSE:To allow a master station to confirm the end of changeover and to prevent mis-connection by allowing a terminal station to send a channel switching end signal to confirm the channel switching operation by the master station when a radio channel of the terminal station is switched. CONSTITUTION:Terminal stations 5<1>-5<n> receiving channel switching signals 6<1>-6<n> sent from a 1-channel master station 3 and a 2-channel master station 4 change over the channel of the own station and channel switching end signals 7<1>-7<n> are sent in the timing assigned at each terminal station. The master stations 3, 4 receive the switching end signals 7<1>-7<n> from the terminal stations 5<1>-5<n> to confirm whether or not the channel of the desired terminal station is changed over. Thus, mis-connection is prevented. |
