PURPOSE:To decrease a load of a central processing type device by installing a monitoring control function to a subscriber circuit. CONSTITUTION:A subscriber circuit 1' has a subscriber interface part 11, a signal processing processor 14 equipped with a PB signal receiving circuit, etc., a program showing a signal processing procedure of the processor 14, a program memory 15 storing subscriber information needed for signal processing and a control circuit 16 transmitting and receiving respective kinds of control signals (b), a sound signal (c), etc. The processor 14 monitors an outgoing call and an incoming call based upon monitoring information transferred from the circuit 16. The circuit 16 identifies a rewriting control signal of the control signals (b) and inputs renewed data included in the rewriting control signal to the memory 15. |
