Hello,
We have a Voice T1/PRI for one of our offices and after 5 days of running fine, we started getting clocking erros. Dropped calls, one way audio - real bad.
We've swapped a lot out at this point and today our PRI provider is saying that we are failing the ALLONES test pattern and I'm hoping that someone can point us in a direction to resolve it? Is there a "usual suspect" when a PRI fails this test?
Thanks in advance.

It usually points to a repeater. I'm going to assume the ones pattern failed on your CSU. I'd have the carrier test to a hard loop on the niu then on the extended d-marc, if one. Then a soft loop on the csu. If the csu is failing the all-ones then you have your culprit.

The provider came in an started with the repeater - then smartjack - then replaced the shelf the smartjack was in. Still failing all ones.
The tried to replace the pairs on the riser panel or house cabling on my floor (16) and couldnt run clean from any they found. We got lucky, a former tennant in this sweet installed a fiber converter at the MPOE and on 16 so we moved over to that an problem solved.
I wonder if they installed the fiber run out of necessity ?
