Abstract
PURPOSE:To prevent a malfunction due to voice, by setting 2-digit personal identification number to a device switching a telephone set and a facsimile equipment, giving a dial, and setting the length of each dial time and the time till the 2nd dial signal. CONSTITUTION:A telephone circuit 4 is connected normally to a telephone set 5 by a contact cml. When a call signal of a facsimile equipment is given to the telephone set 5 and a called party discriminates it as a request of facsimile communication, the same dialing as the preset 2-digit personal identification number is applied. A detection circuit 3 detects a dial signal and gives it to a control circuit 2. The control circuit 2 has the set personal identification number and two timers. When the coincidence is detected from the 1st digit of the identifical number and the length of the timer 1, the 2nd timer is started to decide the 2nd digit of the identification number. When the identification number is coincident, a pseudo signal is sent from the line (a), the facsimile equipment 6 is brought into the automatic incoming state and the contact cml of the relay CML is switched to the position of the facsimile equipment 6. Thus, the malfunction in switching due to voice or holding melody is prevented.
