5.7.3.5.4. Usage Guideline

A system-wide loss plan must be implemented using both input gain and output

gain commands. Other equipment (including PBXs) in the system must be

taken into consideration when creating a loss plan. This default value for this

command assumes that a standard transmission loss plan is in effect, meaning

that normally, there must be -6dB attenuation between phones. Connections

are implemented to provide -6dB of attenuation when the input gain and

output gain commands are configured with the default value of 0.

You can't increase the gain of a signal going out into the PSTN, but you can

decrease it. Therefore, if the voice level is too high, you can decrease the

volume by either decreasing the input gain value or by increasing the output

attenuation

You can increase the gain of a signal coming in to the router. If the voice level

is too low, you can increase the input gain.

5.7.3.5.5. Example

The following example configures a 3-decibel gain to be inserted at the

receiver side of the interface in the router.

port 1/1

input gain 3

5.7.3.6. operation (E&M Voice Port Command)

To set Cabling Scheme for a certain E&M Voice port, use operation command

at voice port configuration mode. To make the singal type back to default

value, use “no” command. This command is for Desctiption.

operation { 2-wire | 4-wire }

no operation
