PURPOSE:To simplify constitution and to shorten the processing time by providing a collating circuit which collates pieces of output information of a control circuit for a timer circuit information memory and a timer circuit with the contents of two memories. CONSTITUTION:The central control circuit 100 of an automatic switchboard connects with a group 101 of extensions, an attendant board 103, a specific control panel 102, and a collating circuit 104, which connects with a timer circuit 111, a time call index information memory 107, a memory control circuit 105, a gate circuit 106, a time call order information memory 110, a memory control circuit 109, a gate circuit 108, a start information latch register 112, a registration information latch register 113. The collating circuit 104 gives received extension information new order to edit time call order information and index information, which are stored in the memory 107 and memory 110 by controlling the memory control circuits 105 and 109. |
