From my own personal experience, as well as what I've read in USR's
manual and magazine articles, you can expect most xfers to go
through at 19.2k or higher. Of course your long distance carrier may
be an important factor in this chain, so it may be worth your while
to change ld carrier if you do indeed find that your modems are
often stepping down because of line noise.
