Forward Battery SLIC and Ringing Relay for TR-57 Applications
Electrical Characteristics
Ring Trip Detector
Table 5. 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

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)
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.
