(i'm not with cisco)
I would guess the difference would be added hardware features
and buffering in the PA.
The difference between the PA-A1-OC3MM and the PA-A3-OC3MM card
(for example) was that the A1 had something like a 40 cell buffer,
and the A3 had a much larger buffer. In a previous networking life
there were problems with large packets when sending over our own
(ick) internal ATM network that we operated. The card would
run out of buffers and drop a cell making the large packets more
susceptiable to problems. The A3 card solved our problem and I believe
cisco actually kindly swapped the A1's for the A3s at the time. (at no
cost to us).
