We have 2 M3Ks and added 2 T1 NI2 ISDN circuite to both M3Ks. One unit the trunks came up just fine and on the orther they refuse to come up. Programing has been double and tripple checked on the 2 units and is the same and the Telco has verified their setup as well as our confirming it with a Berd Dog test set. Cabling is all confirmed good also. Anyone have any ideas?
 
frog the circuits and see if the other one comes up, this should rule several things out

 
Turns out that the very expensive Audio Codes interface cable was not wired correctly. I replaced it with one from an up coming installation and the new one worked fine. Also no bent, broken or missing pins on the defective one.
