Abstract

PURPOSE:To control a transmission time of a multi-frequency signal, without the provision of an exclusive use of transmittion controlling circuit, by controlling a multi-frequency transmission time for a multi-frequency signal transmission circuit with a dial pulse transmission circuit. CONSTITUTION:A number set to a numerical button DB is stored in a storage circuit MEM and a multi-frequency signal PB switching signal S is inputted to a dial pulse circuit DPS'. In transmitting a re-dial signal PB with this state, the circuit DPS' is started with the operation of the re-dial button and a numeral D1 stored in the circuit MEM is read out to one digit storage circuit L and a numeral D2 is transferred to a PB signal transmission circuit PBS. Simultaneously, the transmitting operation of the dial pulse DP is made at the circuit DPS' and a switching signal MU is transmitted to the circuit PBS. The transmitting time of the multi-frequency signal of the circuit PBS is controlled with the circuit DPS' and the transmission time of the multi-frequency signal is controlled without the provision of a transmission control circuit for exclusive use.
