Re: Multiple T1 transmissions on Cat5E

This sounds like something one of our beloved DataBoyz would think up,
doesn't it?

If I were planning this adventure I'd go find some appropriate ABAM cable or
one of th eseveral 32 pair T-1 screened cables for this job. If they have
the money, I'd include a DSX panel at each end and I'd cut down the output
of those panels on a quality 110 block. At that 110 block I'd intermix the
Tx and Rx leads so jumpers could be run with two pair cross-connect wire
with the Tx and Rx adjacent to each other (that is, I'd terminate the
transmit leads on pair 1, 3, 5, 7, etc. and the receives on 2, 4, 6, 8,
etc.)
