Now that I've looked back over my work for the past few days I realize that
I was trying to play with the txgain/rxgain to adjust the levels and hope to
smooth out the line noise. Well, any integer other than zero for either of
those values causes BLUE alarms and all the channels to reset in Asteri

make sure the d4/ami match up with what the pbx is expecting. without docs
its impossible to guess.

just out of curiousity - what are you paying for a T1 cable that you are
worried about cost ? you do realize

no - the stuff you found relates to configuring one 64k channel of the T1,

Hardware, possible. Unlikely to be cabling. It's usually a timing setting.

Which side shows the slips?
I am not that familiar with T1, Are you sure
Well that would explain the choppy/stuttering sound we get on these
calls
since there is no audio during those error transmissions.
According to Kevin's reply I had my timing logic backwards. Should

That is incorrect. You have your span configured to recover timing from
the T1 and use that as the source for the card. If you want this span to
