Input impedance
The impedance at tip and ring is 600 Ohm with a return loss of
20
The impedance at tip and ring is 600 Ohm with a return loss of
20
for 200-500 Hz
26
for 500-3400 Hz
Insertion loss
On a station line-to-line
the total insertion loss at 1 KHz is 6dB
This is arranged as
loss for analog to PCM and
loss for
PCM to analog.
