If the IAD feeds telephone circuits into a legacy PBX or other equipment that defines transmit and receive levels to the network, the loop gain value must match the value of the circuit it supplies—the levels set and determined by the PBX or terminating equipment manufacturer.

You must also change the loop gain value if there is a decrease in power between the signal transmitted and the signal received due to loss through equipment, lines or other transmission devices, degradation in service or customer perception.

NOTE Loop gain values should only be set by your Network Administrator.

To set loop gain values, type G to display the Configure Loop Gain menu:
