Cross over cable won?t have anything to do with the D channel. If the T1 comes up then the cable is fine. I.e. If both ends are getting timing & framing then the cable is good. For the D-channel down make sure you are setting both ends to the correct ISDN mode, D channel on 23 and all that. -- Matthew S. Crocker President Crocker Communications, Inc.

So two different answers :)

It's a 904 connecting on the t1 0/2 DSX interface.

The main issue is that we keep getting D channel is DOWN.

I've run through every step in the Adtran troubleshooting guide (https://supportforums.adtran.com/servlet/JiveServlet/previewBody/4521-102-2-... <https://supportforums.adtran.com/servlet/JiveServlet/previewBody/4521-102-2-...>) and still get the message. We've matched all setings on the Shoretel side with those in the Adtran..

And I do have a ticket in with Adtran. But they take forever to call back :)

It does appear that when they connect the the Adtran 904 for the Shoretel via a crossover cable the PRI interface itself stays down. A straight ethernet and the connection does come up. But the D Channel remains down.

Thanks David

Am I correct that a cross-over cable is needed and not a straight thru cable? The IT vendor and I are having a small disagreement.

Thanks David

Hello, For a TA9xx, you should use a straight T1 cable (standard Eth wiring will work). For a TA9xxE, you will need a crossover T1 cable. If the physical T1 is coming up but your PRI stays down, your wiring is likely correct and there?s a config mismatch. Adtrans always use channel 24 as the D-channel (regardless of the number of B-channels in use) so make sure the settings match on the phone system.

All, Thanks a ton for the feedback! We didn't have boots on the ground so visibility was difficult. I really appreciate the responses. It was a 904 on the T1 0/2 interface. A straight ethernet worked just fine. It turns out that there were two issues. 1) There was a cable crimping issue (I know, right) 2) The PBX was configured as a fractional T1 (16 channels) and we had the 904 configured for the full 24 channels. Again. Thanks to everyone! On Fri, Oct 31, 2014 at 2:18 PM, Jay Hennigan <jay at west.net> wrote:

The main issue is that we keep getting D channel is DOWN.

If the T1 interface itself is up, the cable is correct.

The 904 has two T1 interfaces and only T1 0/2 can be used for PRI. When connecting this to a PBX, a straight-through cable is most common.

Any of the "e" series TA900 flavors have four T1 interfaces. T1 0/3 and/or T1 0/4 can be used for PRI, and these will generally need a T1 crossover (1,2 swapped with 5,4) to go to a PBX.

If the T1 is up but the D-channel is down, it isn't the cable. Check timing source, switch type, that the PBX uses channel 24 for D-channel, user vs. network role configuration, etc.
