Upgraded from 5.0 to 7.5 on our CS1000

now getting this error.

PRI245 DCH: 20 DATA: 0 4

PRI0245
Database Error: Missing PNI number in the customer data block. Output
data: DCH: x DATA: y z . Where:
x = D-channel number y = Customer number
z = Service ID
Look into the customer data block to configure the PNI.
Severity: Critical

Any Idea what this is? We are getting a lot of them.

PNI=0 in CDB

This is a point to point that goes to a remote option 11. That 11 has rebooted at 3:45 AM the last two Thursdays. Do not know why. Related?

when you upgrade did you also upgrade the T1 card as required by Avaya?

No, the vendor did the upgrade. What release should it be?

In the last 30 days I have upgrade 3 Option systems and Avaya formal position is the T1 must be upgrade. In fact, it held up my upgrade on one of my Option 11 upgrade for 3 months because of the back order on the T1 cards. When they arrived I had problems with the PRI card only. The non Pri-T1 worked fine it was the Pri circuits I had problems with. After working with Avaya's Tier 3 techs for 3 cut attempts and 60 hrs later I went back to the old T1 cards. I still have a tier 3 ticket pending with Avaya on this issue. Earlier this week I was speaking with another tech and he also had the same issue. He informed me it is now a know issue and pending patch.
This might not be your issue would need more information about the current version and card version

We've had 2 upgrades to 7.5 go south. None like this but a question Robin, have you heard of upgrades completing then a few days later the system crashing? In both instances we had to downgrade and we used different main cards. We also had a weird issue once with one way speech path but replaced that media gateway and that solved that issue.
