We just completed a VERY difficult installation of a pair of MUXs over
a leased line from Dallas to Austin, Texas.

It may be relevant to anyone soon to do a similar project.

The only real difficulty was that Southwestern Bell is pushing to set a 
new standard for the rest of the world.  They now require their field
service people to install eight wire (RJ48S I think - more about that later)
connectors on their leased lines.  They are unwavering in their desire to
make life as bad as possible for us low lifes who have to deal with this
stuff.  
The tech who installed our lines didn't even know what kind of connector
it was that he was installing, but simply wrote 'eight wire' on the thing.
I cussed and threatened, but he wouldn't change it.  He suggested that
radio shack might have an adapter, or that I should contact 'my provider'.
Chew on that for a minute.  Wasn't HE my provider?  Anyway, I let him
get away without fully understanding the true nature of my problems.

I will list them for you, and the only good solution.

1. NOONE makes a RJ48S to RJ11 adapter.  In fact, few people even know
	what that is.  In fact, they aren't even sure what to call the
	thing.  I heard 'RJ75', 'RJ45', and someone at MCI said it has
	to be a RJ48S if it uses 4 wires.
2. Southwestern Bell cannot help you.  Their own people do not know the
	correct wiring for an adapter (after 10 days, I gave up).
3. Even the modem/MUX manufacturer that I dealt with was no help.  They
	claimed that they had done this once before, and maybe sales
	could FED EX me a cable.  (It was that 'maybe' that bothered me)

Solution:
	Have someone run an RJ11 directly off the the connector posts.
	There is a set of outputs there.  SWB now has a special modem on
	each end, and the connector post is located on the bottom.  Look
	for the line in, there is a set of outputs right on the same set
	of connector posts.  Forget trying to 'make' a cable.
