MICS 4.1 w/PRI ---- WRONG!

I've got a customer that I picked up a few years ago and I've been after them to upgrade to 7.1 so they won't have software issues in the future and of course they're dragging their heels on it.

Now they're starting to have weird problems that may or may not be attributed to the software issue but I'm not so sure. I've seen this kind of software incompatibility create a lot of different problems that seem totally unrelated to PRI but I've never seen this.

They've got two 0 x 8 analog modules daisy chained together and all of the sudden they've got no dial tone or talk battery on any of the ports but I can hear calls ring in on my test set. I figured I just had a bad module and we had a spare on hand so I swapped it out and got the same thing.

After telling myself that I'm a damn fool to even try to troubleshoot a system with PRI that's still running 4.1 software, I thought it might be possible that it's just a bad port on the 6 port expansion card but since I've NEVER seen one fail yet, I'd be shocked if that was it.

Of course I tried enabling and disabling the modules several times and I verified that my tails weren't falling off the modules, fiber connector firmly seated at both ends etc.

I'm about to have to tell them that I can't even get any tech support on that system until we correct the glaring software issue and I'd like to be able to give them some kind of reassurance that when they spend all that money on the major upgrade, it will also solve this problem but I know I can't. lol

Just thought I'd run it by y'all first to see if anyone here has ever seen a PRI software mismatch take out an analog module like that.

Check the Fiber connections and make sure you have a light at both ends. I've seen this with a bad fiber cable.
 
Shouldn't be an issue in compatibility.

Which one did you fix? the loop together so if you replaced the the second one maybe the first one has an issue.

I have seen bad ports on exp cards before as well....does not hurt to swap it out too.

Yeah I was gonna try replacing the connector next and then the expansion card before I push for the upgrade.

I don't have a spare 6 port expansion card in stock but I do have a combo card. Right now the system has a clock card and one 6 port expansion card and I'm thinking if I take those two cards out and test with the combo card, it may not like the system configuration change but I've never tried that.

Guess I'll play it safe and see if I can borrow a 6 port exp card somewhere and then see what happens.
