I recently moved a MICS. On multiple occassions card 1 which is a Caller ID line card goes dead (shows unequipped in the system). Card is there. I swapped out the card, issue returned, then I rebooted the KSU and that clears it. Could this just be power outages / quick outages? There is no UPS but one in the works. Card 2 and Trunk Module seem to be ok. Never seen cards just 'disappear'.

MICS GATC going dead 4

"Nortel used to ship 220 Ohm 1W resistors with the GATC to protect the card from overly high ring trip voltage"
I am curious as to what vintage card this was, and if cards made after that were tried by jssad.
Looks like 3 days up time so far?

I also put in an older CI card (does not stick out) along with the resistors. I have the flaky card, I will let you know the vintage. It has a hologram sticker on the front. I have it in my MICS and it works just fine. There are two other similar new cards in this customer system that work fine. Go figure.

Thanks
That's the exact same card I spoke of above:
"I had a similar frustrating issue on a CICS years ago where the phone system would reboot randomly on an inbound call.
After countless troubleshooting it turned out that line cards ending in D, E and first version F were problematic in this particular case which was a an office trailer in a remote location."
I had posted it as "NT7B75AAAF GATC CLID"
The cards ending in "G" was the fix.
