asterisk users - Aug 2006 - (OT) DS3 Barrel/T-connector/Adtran MX2800 Problems

I have a DS3/T3 that was dropped into my telco closet as two coaxial 
cables.  A send and receive.  I needed to extend it so I went to Radio 
Shack to buy some barrel connectors.  They did not have any but they did 
have T-Connectors so I bought a couple of those. 

Everything was fine up until I went to turn up the seventh set of four 
T1s.  They will not come up, no Asterisk output or greenlight on a 
Digium TE410.  Global Crossing says they only responsible for the DS3.  
I wonder if the T-Connectors could be the problem?

I have already tried the same cables and server on known working T1s and 
they come up fine.  My Adtran MX2800 shows OK for those T1s so I dont 
think the problem is between the Adtran and Asterisk box (as Global 
Crossing claims), I have tried changing to the second controller card in 
the Adtran and also reseated the amphenol connection between the Adtran 
MX2800 and the T1 breakout box. 

Anyone with this kind of experience have any ideas?

I am going to find some real barrel connectors and try that next.

Thanks,
Steve

If you see no errors on your MX2800 for the ds3 then they are  
probably not the issue.

What does the MX2800 show for T1 which do not work? If you loop  
toward * does the card see itself? Loop toward GX do they see?

I am not totally up to speed on the MX2800 but I have gone to loopback 
tests and loop T1 25-28 and selected every possible selection while 
watching pri debug span 1 on the console, no output at all.

The MUX will give you stats for every line running through it, DS1,  
DS2, and DS3. Start there. What errors is it reporting?

Actually I did that backwards, start with DS3 then do DS1, if 3 has  
issues so will everything else.
