Abstract

PURPOSE: To ensure the telephone service in a simple way for the subscriber who cannot receive the short-circuit dial service by detecting the input signal through the control part for start to perform the storage and reading of the input information and giving an identification between the PB signal and the DP signal to transmit the signals.
CONSTITUTION: Push-button 6 of signal type-based switch 5, 0, ... 9 and others for the PB and DP signals, the signal input part such as hook-state detection part 7 and others plus signal output part such as PB signal transmission part 2, DP signal transmission part 3 and others are provided to normal telephone circuit 8. Here, control part 1 detects the input signal from the input part and then operates to carry out the storage and reading of the input information. Thus, an idnetification is given between the PB and DP signals, and the signal is transmitted from part 2 or 3. The electric power is taken in from the circuit via power source 4 to supply the stabilized power to each part by also the incorporated cell. As a result, the telephone service can be given to the subscriber who cannot receive the short-circuit dial service via the exchange.
