We've been helping a group test the 3.0 modems (no LZ compression yet) on
a *terrible* link between the USA and Quito, Ecuador. The line is so bad
you can barely hear. The modems couldn't hear each other either until they
added a small amplifier (20 dB!) to each end. This is normal dialup. Once
the amps were added, the modems connect every time, all the time, getting
6300-6400 bit-per-sec throughput. I'd say this is easily a worst-case scenario.

The only connection worse than this is trying to call Venezuela. Usually, you
can't make the connection because the phone system down there can't put the
call through. Unfortunately, Telebit hasn't solved *that* one yet! :-)
