Fine-Tuning ISDN Voice Ports

Depending on the specifics of your particular network, you may need to adjust voice parameters involving timing, input gain, and output attenuation for voice ports. Collectively, these commands are referred to as voice-port tuning commands.

Note In most cases, the default values for voice-port tuning commands will be sufficient.

To fine-tune ISDN voice ports, use the following commands beginning in privileged EXEC mode:

Step

Command

Purpose

1

Router# configure terminal

Enters global configuration mode.

 

 

 

2

Router(config)# voice-port{shelf/slot/port:D}

Identifies the voice port you want to configure and enter

 

{shelf/slot/parent:port:D}

voice-port configuration mode.

 

 

 

3

Router(config-voiceport)# 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.

 

 

 

4

Router(config-voiceport)# output attenuation value

Specifies (in decibels) the amount of attenuation at the

 

 

transmit side of the interface. Acceptable values are from

 

 

0 to 14.

 

 

 

5

Router(config-voiceport)# echo-canel enable

Enables echo-cancellation of voice that is sent out the

 

 

interface and received back on the same interface.

 

 

 

6

Router(config-voiceport)# echo-canel coverage value

Adjusts the size (in milliseconds) of the echo-cancel.

 

 

Acceptable values are 16, 24, and 32.

 

 

 

7

Router(config-voiceport)# non-linear

Enables non-linear processing, which shuts off any signal

 

 

if no near-end speech is detected. (Non-linear processing

 

 

is used with echo-cancellation.)

 

 

 

8

Router(config-voiceport)# playout-delay{maximum

Specifies the amount of time in milliseconds configured

 

millisecondsnominal milliseconds}

for the playout delay buffer.

 

 

 

9

Router(config-voiceport)# timeouts initial seconds

Specifies the number of seconds the system will wait for

 

 

the caller to input the first digit of the dialed digits. Valid

 

 

entries for this command are from 0 to 120.
