A few quick questions for the 802.3 gurus out there... 1) Is it legal (I think I've seen discussion about this before) to barrel a thickwire segment to a thinwire segment using an N-to-BNC adapter? I think the answer is "wellll, yeah, but..." and I know there's some length loss involved, but I need some specifics on loss, reflections, or whatever. 2) Is it within spec to essentially cascade DEMPR's - i.e. feeding a DEMPR from a thinwire segment connected to another DEMPR? I believe the answer in this case is "no" but again, I need specifics. 3) I know there's an FTP location for RFC's (nic.ddn.mil) but I need a list of RFC numbers and their titles, if such a thing exists, so I know which ones to grab. Thanks in advance...please reply directly to me to save bandwidth and I'll post a summary if there's interest.

1) Is it legal (I think I've seen discussion about this before) to barrel a
thickwire segment to a thinwire segment using an N-to-BNC adapter?
Obviously the worst case is to design the whole thing to 10 BASE 2 (Thinwire)
standards, that is 185 Meters/30 Stations. In that case, the yellow wire
is just a bit over the spec.
2) Is it within spec to essentially cascade DEMPR's - i.e. feeding a DEMPR from
a thinwire segment connected to another DEMPR? I believe the answer in this
case is "no" but again, I need specifics.
The answer is yes, sort of. DEMPR's are repeaters. The rules say no two
stations may have more than two repeaters between them.
3) I know there's an FTP location for RFC's (nic.ddn.mil) but I need a list of
RFC numbers and their titles, if such a thing exists, so I know which ones
to grab.
There is an RFC index "<RFC>RFC-INDEX.TXT" the same place the RFC's are.
