Electrical Characteristics
Ring Trip Detector
Table 6. Ring Trip Detector
1. The ringing source may be either of the following:
2. NDET must also indicate ring trip when the ac ringing voltage is absent (<5 Vrms) from the ringing source.
3. Pretrip ringing must not be tripped by a 10 k
PPM
Table 7. PPM
1. PPM signal should be ac coupled into PPMIN.
2. This parameter is not tested in production, it is guaranteed by design and characterization.
Voltage at Input that will Cause Ring Trip After Appropriate
Voltage at Input that will Cause Immediate Ring Trip
Ringing Source
Ring Trip (NDET = 0)
PPM Source
Signal Gain (from PPMIN to amplifier outputs)
Harmonic Distortion
Isolation (nontest states)
Isolation (test modes)
Zero Crossings
a.) The ringing source consists of the ac and dc voltages added together (battery-backed ringing); the ringing return is ground.
b.) The ringing source consists of only the ac voltage (earth-backed ringing); the ringing return is the dc voltage.
