Abstract

PURPOSE:To perform economical and simple control, by storing the data for signal transmission time in a signal memory for each dial number, reading out all the addresses for the signal transmission through external start and transmitting all the dial numbers for a prescribed time selectively. CONSTITUTION:The address of signal memories 501-512 which store multifrequency dial signals (PB signals) corresponding to all the numbers and codes is sequentially designated from the initial address by the address designation circuit 513 by a control circuit 514 and the operation is stopped when the final address is finished. The connection between a PB sender PSB and a highway HW is made by assigning a time slot to highway gates HG101-HG112 provided for the memories 501-512 corresponding to all the dial numbers, supplying cannel pulses and opening the gate corresponding to the PB signal to be transmitted. The supply of the channel pulse is made by setting provided data of time slot from a central control section to a channel control circuit.
