Abstract

PURPOSE:To enable incoming call of exclusive line and call back transfer, by connecting the incoming call from the office line after night change-over to the subscriber through the use of the exclusive line incoming call function. CONSTITUTION:The private branch of exchanger has the call back transfer function for exclusive line incoming call, the night transfer unit NTT is selected to the night relay board NTTBOX where the call is connected to the exclusive line trunk PVT. The office line incoming call after night change-over is incoming on the night relay board NTTBOX through the night transfer unit NTT, and when the operator hears the subscriber telephone number A and dials it, the incoming call is incoming to the subscriber A through the trunk PVT via the message channel 1 of the network NW for communication. After that, when the subscriber A hooks on, dials the telephone number of the subscriber B, tells the transfer and hooks off the receiver, the operator starts communication with the subscriber B. The private branch of exchange connects the message channel 2 as the call back transfer request and cuts off the message channel 1.
