Maybe it's the fact that the tech working on the switch is a heavy use
dial-up customer that gives me my apparently misguided optimism. I have
problems, he has problems. ;)

Sure there is an excuse. It's "We only have to provide voice service. We're
not required to provide any guaranteed data rate on voice circuits.". Now
they can "refuse to spend money".
And i may be wrong, but my understanding of the SLC's is that you can shove
2 voice lines into one 56k circuit(or more accurately, 48 channels in a
T-1), so even if you don't have any additional A-D conversions, you're
physically limited to a 28k data path, hence, 26.4k connects regardless of
the modem used. Is that wrong?

But no KFlex through there, right?

Backsliding to what? They still provide voice service at an "acceptable"
quality, and I've never heard of anyone getting any telco to admit to any
level of service that's covered by the PUC other than that. Guaranteed
levels of data tranmission are only on dedicated circuits, from my
understanding. All our dial-up customers are using "voice" lines. Works for
voice, PUC is happy.

Anyone doing this? Haven't heard of anyone diving into this yet.
