FIELD: radio engineering; communication systems.
SUBSTANCE: proposed invention can be used in designing national mobile and stationary radio communication systems including effective industrial and technological ones, as well as mass produced radiophone systems. Transmission initiation time is proposed to be recorded for each of channels passing "Channel free" broadband control signal, data on transmission initiation time is to be transferred simultaneously with "Channel free" broadband control signal, and channel kept free for longest time is to be engaged; it is also proposed to connect second control output of mode-of-operation switch in subscriber code-frequency division system for transceiving by broadband signals to switchboard channel selection input.
EFFECT: enhanced reliability of system due to equalizing operating time of system channel-forming components.
