PURPOSE:To avoid a delay in a MFC signal transfer speed, by requesting the next digit information to an outgoing register OR, when a sender transmits a forward signal to an OS post station. CONSTITUTION:When an outgoing rgister OR receives and stores dial information from an outgoing subscriber with a known method, it catches a sender OS and transfers the 1st figure to relays S0-S7 of the OS. After the OS checks this figure, a relay SK is operative. Thus, the next digit figure is requested to the OR via a contact SK<1> for its preparation, and the transmission of an MF signal which is a forward signal is made from an MF signal transmission circuit 2 to a lower rank station. A reverse signal from the lower rank station is received at a reception circuit 3, and when relays R0-R7 are operative, a check relay RK is operative. The contact (rk<1>) instructs the transfer of the next digit figure to the OR. |
