We usually get D channels on the first channel of the first T1 in an NFAS 
group and the last channel of the last t1.

However, telcos don't always get the order right. I've spent hours trying 
configurations and varying the D channel. Sometimes it's just that they 
number things in a different order than we were expecting. Sometimes, it 
almost appears that they use a dartboard :)
