PURPOSE:To make it possible to store all the incoming call of special No. call in the queuing device QUE in regular sequence, by providing QUE so that it can be connected to the outgoing device in due order in case it is idle. CONSTITUTION:The common control device MKR receives a special No. 1XY through the input device ICT. As far as MKP is concerned, a relay which discriminates the position containing ICT is operated, MKR activates a trunk block connector TBC depending upon the kind of ICT, and TBC activates the queuing device QUE after confirming if QUE is idle or busy. MKR activates QUE and subsequently restores it by connecting ICT-QUE. When QUE has been activated, it stores the sequence of incoming call and transmits a ringing tone to ICT. When QUE has confirmed that the after-device which monitors the working status of the after-device is idle, ICT activates MKR over again from the seuquence for connection, and connects it to the attendant board as usual. |
