Abstract

PURPOSE:To confirm visually the dial pulse transmission by displaying a dial pulse signal transmitted by dialing on a light emitting diode. CONSTITUTION:When a dial pad 100 is depressed, a dial contact in matrix form is closed and a make signal is transmitted to a coding circuit 101. The circuit 101 detects the make signal, encodes it into a binary code of 4-bit constitution and stores it in a memory circuit 102. The stored dial data is outputted as a dial pulse signal at prescribed time intervals, transmitted to a trunk line and a PBX line via a network 105 and then fed to the light emitting diode 104. As a result, since the presence of the dial pulse transmission is displayed on the diode 104 in synchronizing with the dial pulse signal transmitted to the trunk line and the PBX line, the dialing is confirmed visually.
