I'm out of ideas...

DX-120 with 4 COs.

Customer is complaining of dropping calls mainly on one line, but sometimes all lines. I have never witnessed the event.

Customer has a DX-120 and they keep dropping calls. I've swapped the cabinet & cards. I've ran a new wire in from the NID to the punchdown. I've removed the ditek surge suppression on the lines.

I've had Verizon out twice. The first time they said there was a "10K short on all the lines". I assumed this to be the Ditek line surges. I had them out a second time (diteks weren't in place) and they found no trouble, but I think they are bringing the lines in on a different pair from the C.O.

Anyone have any insight? or Suggestions?

Thanks
Tylan
