ITG card getting restart automatically

[bala76]

Hi,

We have a Nortel 11c mini with 2 T1 PRI cards, 1 IPL and 1 ITG trunk card. All the other cards are working without any issues. But ITG trunk card getting restarted automatically. So all my far end calls are getting disconnected often. Am in problem. Would appreciate if some one help me to resolve this.

When you say restarted are you talking about the card rebooting or are you talking about the DCHL going down and restarting? Is QOS turned on in the Dial Plan part of the ITG trunk? Really more info is needed to try and evaluate your problem. What release ITG trunk are you using? Has anyone evaluated the data network the trunk is riding over? I can tell you that the data people will tell you that their network is running fine always. From experience just because the data runs fine does not mean the VOIP works great. All the troubles I have experienced with ITG trunks has been traced to the data network causing the problems.

You are right. DCH goes down and when we tried to ping the ITG. not able to. We have Release 3 ITG card. Basically am voice cum data person. I run through the network. There is no problem with the LAN. Suggest me what to test.

There are no errors in ITG console. But M1 shows that the card getting restarted and LED goes ON in ITG card.

It sounds like your ITG card is resetting. Are you getting XMI001 X Y Z (X= loop, Y= Shelf, Z= Card) and XMI002 X Y Z? The XMI001 is the card rebooting and the XMI002 is the card coming back on-line. If the card is the one with the D-Chip, you will also see the DCH releasing or no response.

You need to capute the events from the ITG card before and after the reboot. You could have some drive C: corruption on the ITG card. When the event log get to a certain size it will cause the drive to think it is full. It will then reboot to clear the condition.

You may need to contact your vendor or Nortel if you are a COAM.

Good luck
