INCOMING SERVICE REGISTER SYSTEM

摘要

PURPOSE:To register the start-stop of incoming service in accordance with hooking information from a subscriber by providing a line corresponding device in accordance with a subscriber's line. CONSTITUTION:When a monitor and repeating part 11 detects hooking-off of a subscriber 1, the subscriber 1 is connected to an originating register 4 and hears a dial tone. When the subscriber 1 hooks on the receiver, a hooking discriminating part 12 discriminates hooking information through the monitor and repeating part 11 and transmits back confirmation information of the register state, which is held in a service register memory 13, to the subscriber 1. The subscriber 1 finds the register state (incoming service is performed or released) by confirmation information and hooks off the receiver again if necessary. The hooking discriminating part 12 discriminates hooking information again and changes the held register state of the memory 13 and transmits back confirmation information to the subscriber 1 again.
