To fine-tune FXO or FXS voice ports, use the following commands beginning in privileged EXEC mode:
:
Command
Step 1 configure terminal
Step 2
voice-port
slot-number/subunit-number/port
Step 3
echo-cancel enable
Step 4
echo-cancel coverage value
Step 5
non-linear
Step 6 timeouts initial seconds
Step 7 timeouts interdigit seconds
Step 8 timing digit milliseconds
Step 9 timing inter-digit milliseconds
Step 10 timing pulse-digit milliseconds
Step 11 timing pulse-inter-digit
milliseconds
OL-3592-02
Nonlinear processing using the non-linear command
Initial digit timeouts using the timeouts initial command
Interdigit timeouts using the timeouts interdigits command
Timing other than timeouts using the timing digit, timing inter-digit, timing pulse-digit, and
timing pulse-inter-digit commands
Purpose
Enter the global configuration mode.
Identify the voice port you want to configure and enter the
voice-port configuration mode.
Enable echo cancellation of voice that is sent out the interface and
received back on the same interface.
Adjust the size (in milliseconds) of the echo cancel. Acceptable
values are 16, 24, and 32.
Enable nonlinear processing, which shuts off any signal if no
near-end speech is detected. (Nonlinear processing is used with
echo cancellation.)
Specify the number of seconds the system waits for the caller to
input the first digit of the dialed digits. Valid entries for this
command are from 0 to 120.
Specify the number of seconds the system waits (after the caller
has input the initial digit) for the caller to input a subsequent
digit. Valid entries for this command are from 0 to 120.
If the voice-port dial type is DTMF, configure the DTMF digit
signal duration. The range of the DTMF digit signal duration is
from 50 to 100. The default is 100.
If the voice-port dial type is DTMF, configure the DTMF
inter-digit signal duration. The range of the DTMF inter-digit
signal duration is from 50 to 500. The default is 100.
(FXO ports only.) If the voice-port dial type is pulse, configure
the pulse-digit signal duration. The range of the pulse-digit signal
duration is from 10 to 20. The default is 20.
(FXO ports only.) If the voice-port dial type is pulse, configure
the pulse inter-digit signal duration. The range of the
pulse-inter-digit signal duration is from 100 to 1000. The default
is 500.
