I have 3 PRI's in the same trunk group.
There are 22 B channels on the first one, 20 on the second and 20 on the third.
Should there not be one A channel on each T1 and 23 B channels? It's been a long time since I worked on this stuff and I don't recall exactly how it all works.
I have an old G3siV11, not that it makes any difference.
