You may very well want to switch to immediate start. I finally got US
West to start processing this order. The wink start timing on the PM3 is
something like 140-240ms and US West, at least where we are in Gallup
(a town near Greg here in New Mexico for the curious) is expecting it to
be between something like 210-240ms only.. this seems to be causing a LOT
of inital connection problems and perhaps contributing to the high-load
disconnects on the other channels (no idea - going to find out when they
switch it next week).

Same here..

You are running 3.7.1c1 right?

Weird.. c1 fixes the ADMIN problems.

Yeah.. c1 also fixes some random disconnection problems.
Right now we're seeing problems with almost always USR Telepath/Sportsters
and some Practical Prepherials modems..
