Electrical Characteristics
(continued)
Table 11. Ringing Specifications
1. Voltage is measured across both resistive and capacitive elements of the ringer load.
2. Voltage is measured only across the resistive element of the ringer load.
Table 12. Ring Trip
Ringing will not be tripped by the following loads:
I
100
resistor in series with a 2 μF capacitor applied across tip and ring. Ring frequency = 17 Hz to 23 Hz.
I
200
resistor switch for less than 12 ms, applied across tip and ring. Ring frequency = 17 Hz to 23 Hz.
I
10 k
resistor in parallel with a 4 μF capacitor applied across tip and ring. Ring frequency = 17 Hz to 23 Hz.
