Title: Ring trip circuit
Inventor: NAKAJIMA TAKASHI
IPC: H04M3/02
Filed: 1990-11-26
Abstract: PURPOSE:To eliminate erroneous detection by ignoring the detected signal when a ring trip signal disappears during a first guarding time and ignoring the ring trip detection signal while a second guarding time started by an immunity detection signal is continued. CONSTITUTION:A first invalidating means 105 is activated by the ring trip detection signal and the first guarding time T1 is started, during this time the ring trip detection signal is ignored when the ring trip detection signal of a ring trip detection circuit 103 disappears. Also a second ignoring means 106 is provided with the immunity detection signal from an immunity detection circuit 104, by which a second guarding time T2 is started. Then the ring trip detection signal of the ring trip detection circuit 103 is ignored while the second guarding time T2 is continued. Thus adjustment by volume is eliminated and the erroneous detections caused by temperature variation as well as change with the lapse of time are prevented.
