56K Troubles: Anyone for sharing/comparing?

Maybe we can find a common thread here. Again, I'm a little confused
since we can get such good connect rates with v.34, but can't do anything
with K56Flex.

GTE covers most of the local area. They use SLC-5's almost everywhere. My
4 PRI's come directly out of a GTD-5. 2 of them originate from another
GTD-5, and 2 of them originate from an ATT-5ess (GTE's MetroLan service
routes them into my switch). I'm running NI-2 on all of them. I'm under a
mile from the CO.

Anyone else want to compare notes?
