From what I have been told (by Cabletron) is that a 10 Base-T compliant
product can go over the same cable with the phone.  Note, however, that
10 Base-T does not use a USOC jack, but rather the "new" AT&T jack (RJ445
I believe).  I haven't seen 10 Base-T used on the same cable as the phone,
but from what I can see from the pin-out and the pair matching, it should
work.  I don't want to waste bandwidth with any technical information, so
if anybody is interested send E-Mail to me.
