PURPOSE:To reduce the cost of line equipment and give a broadcast function and a call function to the system, by adopting a computer for a common control, etc., to constitute the decentralized exchange system. CONSTITUTION:The broadcast exchange system between a toll broadcast station and a cluster is made into a decentralized exchange system, and computer common control-storage part 2 is adopted as a unit which controls broadcasting amplifier 7, where the output of radio receiving unit 14 is supplied, channel part 1, etc. Then, call trunk-miscellaneous circuit 8, tape recorder 6, AC 100V power source part 5, rectifier 4, 12V accumulator 3, etc., are arranged to constitute the system, and trunk line 12 to another cluster decentralized station and the toll station and line 11 to subscriber's telephone sets are connected to the line relay and other additional circuit 9 connected to channel part 1 and broadcasting amplifier 7, thus reducing the cost of line equipment and giving a broadcast function and a call function to the system. |
