Technical summary
Analog line interface
Input impedance
The impedance at tip and ring is 600 Ohm with a return loss of
20
for
Hz
26
for 500-3400 Hz
Insertion loss
On a station line-to-line connection, the total insertion loss at 1 KHz is 6dB
This is arranged as
loss for analog to PCM and
loss for
PCM to analog.
Frequency response
The loss values in the table below are measured relative to the loss at 1
