OK, all you folks with big happy 10Base-T networks, maybe you can help
us out.  We're looking at doing (finally) our first big 10Base-T
installation, and are wondering how to fit it in with our existing
telephone wiring plant.  I'm aware that 10Base-T standardizes the
pinouts when used with an RJ-45 connector, but our plant uses 6-wire
RJ-11 exclusively.

So, is there a standard for use of RJ-11 pins for 10Base-T?  If not,
how have others in this situation established their internal
standards?  Presumably the way you use the pairs for voice or other
data connections will have some influence on this.

In particular, we'd like to buy off-the-shelf twisted-pair jumper
cables to connect between the RJ-45 connector on the computer's
10Base-T adaptor and the RJ-11 on the wall.  Are these available from
some place?  Do they have a standard for how they make them up, or do
people just custom-order?

Thanks,
