Electrical Characteristics
(continued)
Table 3. Battery Feed, Switchhook Detectors (LCA and LCB), and Fault Detectors (FLTA and FLTB)
1. Assumes 2 x 300
external dc feed resistors.
2. Detector values are independent of office battery and are valid over the entire range of V
BAT
.
3. Fault voltage is defined as the absolute value of the dc voltage across either dc feed resistor. If the voltage across either feed resistor
exceeds this value, a fault is determined to be present. FLT is forced to a 0 when D2 = 1 (ringing state).
Table 4. Ring-Trip Detectors (RTA, RTB, RZA, and RZB)
1. The ringing source consists of the ac and dc voltages added together (battery-backed ringing); the ringing return is ground.
2. RT 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
resistor in parallel with an 8
μ
F capacitor applied across Tip and Ring.
