Re: (ASCEND) how is this PRI setup???



Actually it was the 24 channel being set incorrectly. Since this was
a single PRI ISDN box before and we just added another line on this
group I forgot to change to 24th channel on the lines.

The fact that GTE cant seem to grasp how their lines are setup
and the fact they changed the programming 3 times with this order
didnt help me a bit :)

Strange one though, they first set this line up to hunt randomly
instead of sequencially like all our other lines.

We have to use NFAS here as GTE only has GTD-5 swtiches here. 
Well, at least the ones that arent rotary...

Still wish I could asn the Ascend for a dump on what they think all the
channels are doing...

Thank for all the help,
