I'm connecting a Adtran 904 to a Shoretel system for a voice only PRI.
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

If you are connecting it directly, then generally yes... a crossover. If
there's anything in-between the two, then generally the answer is no.

If it's a 904 (not 904e) and you're using the DSX-1 port no crossover cable
required. Straighthrough it is.

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 (
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
Straight through should be fine, that is all I’ve ever used coming out of an
Adtran.
remember, Cross-over Ethernet != Cross-over DS-1 cable

I have always done 1 to 4, 2 to 5.
But as I read below this is incorrect.
To add further confusion, google returns both as valid.
So what is the correct one?
Technically, 1-to-5 and 2-to-4 is correct but either should work. The
other way
