Using Loss Plan Defaults

This appendix describes how to use the loss plan defaults.

Default Loss and Gain Values

When the CLI indicates the default Transmit (T) Input gain / Receive (R) output loss pads is 0 dB, the actual level for each of the VIC modules is:

FXS : T = 0 dB and R = 3 dB
FXO : T = 0 dB and R = 3 dB

This system does not have pre-configured transmission loss plan settings. Therefore, it is important to set the loss plan for your network with the fixed loss pads on each VIC module. Use the following commands to set the loss plan for your network:

Command
Purpose

input gain value

Specify in decibels the amount of gain to be inserted at the receiver side of the interface. Acceptable values are from -6 to 14.

output attenuation value

Specify in decibels the amount of attenuation at the transmit side of the interface. Acceptable values are from 0 to 14.

Command	Purpose
input gain value	Specify in decibels the amount of gain to be inserted at the receiver side of the interface. Acceptable values are from -6 to 14.
output attenuation value	Specify in decibels the amount of attenuation at the transmit side of the interface. Acceptable values are from 0 to 14.
