Cisco Catalyst 4000 Access Gateway Module Installation and Configuration Note

APPENDIX

Using Loss Plan Defaults

This appendix describes the loss plan defaults on the Cisco Catalyst 4000 Access Gateway Module

(AGM).

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

Transmission Loss Plan

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:

For North American private network, see draft PN-4819 (to be published as TIA/EIA/TSB-122).

Command Purpose

input gain value Specifies 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 Specifies in decibels the amount of attenuation at the transmit

side of the interface. Acceptable values are from 0 to 14.
