OK, then to rephrase your initial message (if I may presume to do so):
1. We have intermittent CID failures on all NEWLY INSTALLED lines JUST FOR THIS ONE SUB.
2. We have lines OPEN at the MDF for testing, and we still get failures.
3. We have changed the OE's as a precaution.
4. The trouble follows the numbers, not the OE's.
Here are some questions:
1. Are you aware, or can you determine, if other subs are having the same problem, but perhaps not reporting it, due to its intermittent nature? Some subs do not have the same level of tolerance for intermittent problems with ancillary features.
2. While you were at the CO (laptop plugged into the MDF, I assume) you say the outside lines were "removed." Do you mean that the heat coils were pulled while you ran your tests?
3. Did you happen to dial 20 or 30 test calls to any OTHER randomly-chosen lines in the same carrier? Other carriers?
4. When the OE's were changed, were they changed to ports that were in other carriers of the switch?
5. When you ran the tests, did you dial from random calling number(s), always the same calling number(s), official numbers, sub's numbers?
