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?

High or low loop current can cause the data burst to get "lost" or "garbled" between the customers Demarc or NID and the CO. I'm not really sure I understand where your test point was, so its really hard for us to diagnose.

Wow. I think he knows what he's doing. He just wants to know if anyone else has seen this problem out of a switch.

Arthur has a valid point, test other lines out of the same CO to see if they fail intermittently also.

Bottom line it's been proven to the CO and Phony would like to know if anyone's seen this problem before.

He says the lines were "removed" at the MDF. Waiting for confirmation that he means the coils were pulled.

Now that we have filtered the facts, I suspect the CO is acting up in general, not just on his lines.

I have turned off the TV, and am eagerly awaiting the next set of answers.

He said he was an outside tech. They usually don't do testing at the co. Wrong assumption. Have a good night justbill

You can try to have your switch tech remove and rebuild the features in the switch. Also sent you a PM

I have tested other lines in the central office, at the Office equipment, with the outside lines off and got no failure. This was also my assumption, that others just did not care that this was haapening. I have been working with a c.o. tech with 40 years experience in this switch and has never seen this trouble. Rest assured when, and iff this gets corrected, and I am made aware of what is the cause, I will let you know here what we have found.

I think this would fit better in the Telephone service category. Going to leave it here also since there've been so many replys. Don't want anyone to think it got lost.
