Step 2 Compare the displayed MTP3 timers to the MTP3 timers on the associated destination.
If the MTP3 timers settings match, the timer settings are not causing the signaling problem. Check for
alarms on your system and resolve them using the procedures in the “Alarm Troubleshooting
Procedures” section on page 6-4.
If the MTP3 timers settings do not match, proceed to Step 3.
Step 3 Start a provisioning session by using the procedure in the “Starting a Provisioning Session” section on
page 3-64.
Step 4 Modify the parameters for the desired MTP3 timers by entering the
prov-ed:lnkset:name=“protocol”,param_name=param_value command.
Where:
• protocol—MML name for the SS7 protocol family, such as SS7-ANSI or SS7-ITU.
• param_name—Name of the MTP timer you want to change.
• param_value—New value for the MTP timer.
Note See Cisco PGW 2200 Softswitch Release 9 MML Command Reference for more information on the
parameters for this command.
In the following example, the MTP3 T1 timer, waiting for signaling link test acknowledgment message,
is set to 65 tenths of a second.
prov-ed:lnkset:name=”SS7-ANSI”,mtp3tstSltmT1=65
Step 5 Save and activate your provisioning session by using the procedure in the “Saving and Activating your
Provisioning Changes” section on page 3-65.
Step 6 Reboot your system as described in the “Rebooting Your System to Modify Properties” section on
page 6-117.
