Chapter 7 Configuring the Eight-Port FXS RJ-21 Module
Command
timing digit milliseconds
timing inter-digit milliseconds
OL-2031-02
Purpose
If the voice port dial type is dual tone multifrequency
(DTMF), configures the duration (in milliseconds) of the
DTMF digit signal. The range of the duration is from
50 to 100; the default is 100.
If the voice port dial type is DTMF, configures the duration
(in milliseconds) of the DTMF interdigit signal. The range
of the duration is from 50 to 500; the default is 100.
For complete information about configuration commands and about configuring
LAN and WAN interfaces on your switch, refer to the Cisco IOS configuration
guides and command references.
The following example shows how to use the fine-tune FXS commands:
Gateway# conf t
Enter configuration commands, one per line.
Gateway(config)# voice-port 4/0
Gateway(config-voiceport)# input gain 10
Gateway(config-voiceport)# output attenuation 10
Gateway(config-voiceport)# echo-cancel enable
Gateway(config-voiceport)# echo-cancel coverage 8
Gateway(config-voiceport)# non-linear
Gateway(config-voiceport)# timeouts initial 10
Gateway(config-voiceport)# timeouts interdigit 10
Gateway(config-voiceport)# timing digit 60
Gateway(config-voiceport)# timing inter-digit 60
To display the values configured, use the show running-config command, as
follows:
Gateway# sh running-config
!
voice-port 4/0
input gain 10
output attenuation 10
echo-cancel coverage 8
timeouts initial 10
timeouts interdigits 10
timing digit 60
timing inter-digit 60
