Abstract

PURPOSE:To make small the capacity of exclusive control channel by transmitting the control information via the communication channel through the allocation of one of the communication channels in the time frame information for the exclusive control channel during the transfer of control information. CONSTITUTION:The master station 1, remote line concentration unit 2, and dispersion type line concentrators 12-0 to 12-l are connected with the transmission line 6. The master station 1 consists of the highway switch 3, master station controller 4, master station synchronizer 5, and the signal processor 19, and the remote line concentrator 2 comprises the line concentrator 7, remote line concentration controller 8, remote synchronizer 9, subscriber circuits 10-0 to 10-k and 11-0 to 11-k, and the dispersion type line concentrator 12 is made up of the remote terminal RT, subscriber circuit and subscribers.
