To verify and modify the values that are used for the ISUP timers, complete the following steps:
Step 1 Unless you previously created a profile for the associated signaling service or trunk group with modified
values for these ISUP timers, the values for these eight timers match the default values listed in the
preceding table. If you previously created a profile with modified ISUP timer values for the associated
signaling service or trunk group, proceed to Step 2 to retrieve the current values that are set in the profile.
Otherwise, proceed to Step 3.
Step 2 Log on to active Cisco PGW 2200 Softswitch, start an MML session, and enter the
prov-rtrv:profile:name=“profile_name” command to display the settings for the modified ISUP
timers.
Where:
profile_name is the MML name for the profile that contains the modified values for the configurable
ISUP timers.
The system returns a message like the following:
MGC-01 - Media Gateway Controller 2002-10-07 15:47:39.928 EST
M RTRV
"session=NOA_SPAIN:profile"
/*
ProfileType PropertyName ProfileValue
-------------------- -------------------- -----------
isuptmrprofile T1 5000
*/
Step 3 Compare the displayed ISUP timers settings listed to the ISUP timers on the associated destination.
If the ISUP 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 ISUP timers settings do not match, proceed to Step 4.
Step 4 Start a provisioning session, using the procedure in the “Starting a Provisioning Session” section on
page 3-64.
Step 5 If you have already defined a profile that modifies the configurable ISUP timers, proceed to Step 8.
Otherwise, proceed to Step 6.
Step 6 Enter your new ISUP timer values using the
prov-add:profile:name=” profile_name ”,type=”isuptmrprofile”, timer_number =” timer_value ” ,
timer_number
=” timer_value ” , timer_number =” timer_value ” ... command.
Where:
• profile_name—MML name for the profile that contains the set of ISUP measurements in use.
• timer_number—Number of the timer you want to modify.
• timer_value—New value for the selected ISUP timer.
Note See Cisco PGW 2200 Softswitch Release 9.8 Provisioning Guide for more information on the valid
ranges for the ISUP timers. If you enter a number outside the valid range, the default value is used.
In the following example, the command modifies the values of the T6, T8, and T35 ISUP timers:
prov-add:profile:name=”set1”,type=”isuptmrprofile”,T6=”30000”,T8=”12000”,T35=”18000”
