Abstract
PURPOSE:To realize a direct answer of a subscriber of a remote line concentrator to a trunk line incoming of a master station, by transmitting a trunk line incoming display signal to the remote line concentrator from the master station via an inter- office transmission line and ten receiving and displaying the said display signal. CONSTITUTION:If a trunk line group for a remove line concentrator in a trunk line 140 has an incoming in a state under which the attendant board of a master station is set in the night mode, a central controller 100 of the master station transmits the incoming to a remote line concentrating interface 200 of the remote line concentrator via an inter-office transmission line 400. The interface 200 transmits the incoming to a trunk line display board 220 for a visible and audible display. When a subscriber 230 of the remote line concetrator who notices the trunk line incoming gives an answer to the trunk line, the controller 100 connects a storing turminal of a switching network 120 of a central office trunk 130 to an input terminal of the network 120 corresponding to the subscriber 230. Thus a channel is set between the trunk line and the subscriber 230.
