Title: Ring trip circuit
Inventor: UNZAI MINORU
IPC: H04M3/02
Filed: 1987-12-15
Abstract: PURPOSE:To prevent the occurrence of malfunction even when a call signal is sent to a tip line or a ring line by using an output of a pulse generating section as a gate signal receiving the leading/trailing of an output of a drive circuit driving a call signal transmission relay and generating a pulse. CONSTITUTION:The call signal sending relay 21 is energized according to a drive signal from a drive circuit 4 and the pulse generating section 30 receives the leading/trailing of the drive signal and a pulse whose width is 10-50ms is outputted. The DC potential at subscriber line terminals 102, 103 is changed according to the operation/release of the call signal sending relay 21. Thus, the DC current for discharging/charging the charge stored in a capacitance 6 between lines flows to a loop detection section included in a ring trip section 3 or a feeding circuit 1 for a short time and an erroneous ring trip output is given, since it is ANDed with the output pulse of the pulse generating section 30 by a gate circuit 31, the output is not given to an output terminal 104. Thus, no malfunction is caused.
