Perhaps my definition isn't what's accepted. I got confused by the
10bT wire.

Ah, yeah, the ISDN router is on net 15 so you're correct.

Yeah, the ISDN router is on net 15. What I was thinking about was
connecting net 15 machines (and multi-homed Macs) on 1 wire. The
net 10 NeXTs will go on another wire (ed2). Not really sure about
my Macs since they live on both networks using 1 wire.
