Hmmm, I've seen both -- a high number of "initial slow connects" and also
"frequent hangups".  It also depends very much on the kind of modems that
call in, so you need a high number of calls to get statistically relevant
data out of it.

Another interesting fact might be the number of 56k-capable modems calling
in, vs. "just V.34", vs. "even slower" modems.

Ah, I see.
