Abstract
PURPOSE:To attain small size and low cost for a remote installation type line concentrator by providing a subscriber line signal processing function to a master station side. CONSTITUTION:The state of a subscriber terminal equipment 3 is sent in a terminal station device 6 as an incoming subscriber line signal 80 and connected to an idle slot by a remote subscriber line multiplexer 9 and sent to a master exchange 2 via an inserter 13 and a transmitter 21. The outgoing subscriber line signal 81 sent from the master station exchange 2 is outputted to an idle time slot of the outgoing signal highway 12. The signal 81 is demultiplexed by the remote subscriber line demultiplexer 15 and outputted to a terminal equipment 3 via a terminal station device 6. The connection control signal sent from the master station exchange 2 is extracted by a dropper 11 and enters the control memory 18 and the line designated by the control is connected to an incoming information line 70 and an outgoing signal line 71 by line concentration channels 19, 20.
