Hi, Joe:

I think that a twinAx "A/B switch" is rare enough nowadays to be hard to
find, even on e-bay ... :-o

However, you can achieve much the same effect by using several baluns,
connected by standard phone line with RJ11 connectors at each end. To
"switch" you simply power off the terminal, un-plug the phone cord from one
balun and plug it in to another (connected to the other system) and power on
again.

(At least, this approach has worked well for me, and is MUCH EASIER than
un-screwing the TwinAX connector and the plugging it in to the other
system's break-out box, with much less chance of damaging the little pins in
the TwinAX connector, due to "over-use" ...). And if you wear out the little
RJ11 connector, they are cheap and easy to replace. ;-)

And, best of all, twinAX baluns seem to be readily available at reasonable
prices on e-bay ... ;-)

HTH,

Mark
