Why not try a different brand of mux?  You'll make a lot more changes to 
router configurations over the life of the mux than you will to the mux.

What if it's the fault of the Adtran mux?  Is it fair to blame Cisco for 
that?

I deal with ~40 Adtran MX2820s, some of which go to PA-MC-2T3+ cards. 
MX2820 isn't the same as MX2800 (7xDS3 vs. 1xDS3, and if I understand 
correctly it's completely different hardware), but I'm having the same 
problems as you on muxes that are particularly close to the PA.  The 
problem appeared when we swapped out the CAC WideBank 28s for the Adtran 
MX2820, so hence my thinking that the problem is in the mux.

And yes, I'd try a longer piece of cable.
