Abstract

PURPOSE:To enable a person in charge of maintenance to vary origination control information on every subscriber variously without varying the contents of a data memory, by varying the contents of a temporary conversion class memory by a specific subscriber or B-board operator. CONSTITUTION:According to a program stored in program memory 7, central controller of an automatic telephone switchboard controls switch network 1, trunk 2, telephone set 3 and B board 4 via peripheral controller 5 to perform switching processing. To this controller 6, data memory 8 stored with data required for the switching processing of subscriber's classes, subscriber's equipment positions, origination control information, etc., and temporary conversion class memory 9 in which a specific subscriber or the operator of B board 4 can write subscriber's classes freely by dialing by assigning prescribed bits to respective subscribers are connected. Then, the origination control information on every subscriber can be varied through the dialing of the specific subscriber or the operator of B board 4 without varying the contents of memory 8 by the persorn in charge of maintenance.
