I have a double cabinet DBS 96 and 96 that just got a T-1 installed. I can get the system to work without the ADTRAN ACE CSU but if I try to use the ADTRAN it won't. Do the cables to and from the ADTRAN have to be a certain way? Since it works without the ADTRAN does one of the cables have to be reversed when it goes through the ADTRAN? HELP!! I know that I have to have it per FCC regulations. ANYBODY????

Don't use a CSU.
We won't tell the FCC in you won't [Linked Image from sundance-communications.com]

I know of several people who connect one for an initial install and remove it after the cutover

It sounds like you've either got a bad cable or a bad CSU.

Well, the cable works without the ADTRAN, and I've gotten a new ADTRAN thinking the first one was bad so...I was thinking maybe the cable had to be reversed or something through the ADTRAN but wasn't sure. Do you know?

If you use CAT5 straight-through cables for both the CSU and the T1 card you should be ok. Athough you can probably get away without using a CSU, there may be a day when telco tries to loop the CSU for diagnostic purposes like when the t1 goes down.

I have had this problem before and I think the solution was to reverse the cable from the adtran to the ISDN card in the DBS. Not a crossover, but a complete reverse 1-8 on one end an 8-1 on the other. It was that or maybe I bumped my head. Try it. The cable not bumping your head.

I'll give that a shot. I just went out there yesterday and tried with new cables that were straight through and of course that didn't work so...I'm willing to give it a try. THANKS!!

What type of Adtran unit do you have. I may not be programmed correctly.

It's an Adtran ACE CSU/DSU. It does not have a display. It just has the switches for the distance and that's it.

Also switching the cable didn't work either.
