I am trying to assist another tech with a problem and wanted to see if anyone can confirm this issue or have any input. He has a IP 500 (version unknown at this point but can make a call to find out) with a dual PRI card on a VCM 32 module. System has been working fine for about a year but in the past week one circuit has started taking errors. He was told that it is not a good idea to put PRI daughter cards on VCM cards. Anyone know about this? I have PRI on VCM on a number of systems and have never had an issue. When line is removed from IP Office local telco reports no errors. I had a similar issue when upgrading a system from 4.1 to 5.0(18) but after a couple of power cycles the problem went away. I know there is not much detail here but I am mainly looking for confirmation on the card placement.
