Abstract

PURPOSE:To prevent the ineffective holding of a junction line by changing connection routes for calling. CONSTITUTION:To connect originating subscriber A to subscriber B which has made a contract of new service, marker MKR of the service-cetralized station sets two routes 8 and 9 between trunk TRK and new service trunk NST, and new service trunk NST and terminating subscriber B. Signal receiver SR of the service centralization station, on the other hand, receives information on whether or not terminating subscriber B requests the service at that time from memory unit MEM in process of requesting the new service. Therefore, if terminating subscriber B is in process of requesting the service, subscriber A is connected to new service equipment NSE via signal receiver SR. If not, new service trunk NST cuts off the junction line and connects subscriber A to B through routes 8 and 9.
