Abstract
PURPOSE:To attain the switching and connection between a FAX equipment and a private line and the normal operation of FAX communication by sending a dial signal including a pause time to a line while retarding the signal by a prescribed time at a point of time of reception of the dial signal from the FAX equipment. CONSTITUTION:When a preset time t2 elapses from a point of time of receiving a dial signal from a FAX equipment 2, a CPU 427 generates a dial number stored temporarily in a RAM 429 and a dial signal including a pause time t1 from a DPG 424. Thus. the dial signal received from the equipment 2 is retarded by the time t2 and sent to the private line 3. Moreover, the CPU 427 counts the time t1 at each reception of the DP signal and when the next DP signal is not received even after the elapsed time of the time t1, it is discriminat ed to be the end of reception of the dial signal. Then all the dial signals are sent, then a relay K7 is energized and a relay K5 is released. Thus, even when the dial signal from the equipment 2 includes the time t1, the switching and connection between the equipment 2 and the line 3 and the FAX communication are applied normally.
