PURPOSE:To reduce remarkably office data work when an office is opened by providing a subscriber's terminal classification designating part having a prescribed pattern of logic ''0'' and ''1'', and displaying the output information of the designating part concerned on a central control device at every call of a subscriber's terminal. CONSTITUTION:A subscriber's circuit 2 is installed at every subscriber's terminal 1, and the circuit 2 is provided with a subscriber's terminal classification designating part 3 which is capable of setting manually a prescribed pattern of logic ''0'' and ''1'' corresponding to a classification of its terminal 1. A connecting means 4 is connected between the designating part 3 and a central control device 5, and the means 4 reads a pattern of logic ''0'' and ''1'' set to the designating part 3 at every call of the terminal 1, sends it to the device 5 and displays. Also, the device 5 reads the necessary subscriber's terminal classification information at every call processing from the means 4 as necessary, and basing on it, an operation of a switchboard, to be executed next is determined. Accordingly, when opening an office, it is possible to eliminate completely a work for accumulating a subscriber's terminal classification in a memory of the device 5 by an input/output device. |
