The transmission of the dial tone is delayed or is processed as a busy tone transmission. These are undesirable as they lead to poor service. Further, in order to count selection signals, empty selection is required depending on the type of register circuit, which inevitably increases the complexity and scale of the control program, leading to a decrease in the processing capacity of the central control circuit 60.
