PURPOSE:To ensure an understanding of an absence transfer information for an absence transfer registerer, by comparing a calling subscriber information with a subscriber information that is selected by the information of an absence transferrer. CONSTITUTION:When a central processor CC detects that a subscriber A has called, a channel control device SWC is started to connect the subscriber A to an originating register trunk ORT. Then a registerer A informs both the absence transferrer number and the absence transfer address number, and thus an absence transfer register information is transmitted to the processor CC from a calling subscriber information trunk DET. The processor CC reads the subscriber discriminating information corresponding to the absence transferrer number out of a storing device TM compares it with the calling subscriber information. In case when a coincidence is obtained, the absence transferrer number is registered to the absence transferrer of the device TM. Then a sound of register confirmation is sent back to the subscriber A through the trunk ORT. |
