Electrical Characteristics
(continued)
Table 16. Ring Trip (3 REN Configuration)
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
10 k
resistor in parallel with a 4 μF capacitor applied across tip and ring. Ring frequency = 17 Hz to 23 Hz.
Table 17. Ring Trip (5 REN Configuration)
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
10 k
resistor in parallel with a 6 μF capacitor applied across tip and ring. Ring frequency = 17 Hz to 23 Hz.
Note:
Refer to the application section for further description of the 3 REN configuration vs. 5 REN configuration.
