5.4.2.3. Fine-Tuning E&M Voice Ports
Depending on the specifics of your particular network, you may need to adjust
voice parameters involving timing, input gain, and output gain for E&M voice
ports. Collectively, these commands are referred to as voice-port tuning
commands.
In most cases, the default values for voice-port tuning commands will be
sufficient.
To configure voice-port tuning for E&M voice ports, perform the following tasks:
1. Identify the voice port and enter the voice-port configuration mode.
2. For each of the following parameters, select the appropriate value:
z Input gain
z Output gain
z Timing other then timeout
To fine-tune E&M voice ports, use the following commands beginning in
Administrator command mode:
Change voice port setup using “voice-port” command before
activating/deactivating the corresponding port by “shutdown/no shutdown”
command.
