Title: Line terminal equipment
Inventor: OISHI YOSHIKATSU
IPC: H04M11/00
Filed: 1990-09-05
Abstract: PURPOSE:To improve the identification capability for polarity inversion and to extend the service life of a battery by delaying an output of a polarity inversion detection section and masking an output from a delay section in response to an output of an incoming signal. CONSTITUTION:When an incoming signal comes simultaneously or lapse or a prescribed time after polarity inversion, a polarity inversion detection section 11 starts outputting a signal when the polarity of a telephone line 4 is inverted and its level exceeds 35V, and keeps outputting a signal S2 during the consecutive reception of the incoming signal via a delay section 13 having a time constant of 50ms because an output pulse width of the polarity inversion detection section is set longer than the period of the incoming signal. On the other hand, an incoming call detection section 12 starts outputting a signal in a timing when a line voltage exceeds 70V. As a result, an output CI of the incoming call detection section 12 masks the signal S2 and no signal is outputted from a signal mask section 14. Thus, power supply is consumed for a required minimum time so as to reduce current consumption thereby extending the service life of the battery.
