PURPOSE:To prevent the stopping of incoming call service due to forgotton release of absence transfer registration, through the release of a storage circuit corresponding to the subscriber in which the absence transfer registration is not released at the point of time, with a pulse transmitted in the period of 24hr from a clock circuit. CONSTITUTION:To an absence transfer registration subscriber whom the absence transfer registration is stored all days because of its out of office or forgotten number for registration release, a momentary relay is activated with ground transmitted from a clock circuit 3 for 24hr. Next, relays A1-AX during self-hold of an absence transfer call registration storage circuit 2 are compulsively restored and the subscriber location position information reception circuit is returned to normal state. Thus, normal outgoing/incoming call service can be received. |
