Odd.... Apple hired Jordan Hubbard (lead developer for FreeBSD) to head up
OSX development, and I was quite sure I saw an article where Jordan stated
the kernel and underlying OS was in fact FreeBSD. I'll check into this...

In the what the hell is it category,
I have been given the following items:
Motorola 3261 Codex Modem
3 rj11's, 2 minidin8's, DB25
Motorola SW56-II UDS
1 rj45, 2 DB25's
and
ADtran 2gen TSU
3 rj45's, a 26 pin connector (to T1?)
Are these of any use to me?
Can I use them to replace my 56K modem?
Could I do standalone PPP networking directly
from a phoneline to a10BT hub?

Probably not. They're leased-line modems. The AdTran unit is probably
some sort of CSU for a T-1 as you speculate. Get another one and you can
hook-up your own local T-1 ;)

OK, I don't know much about higher speed setups. I know ISDN is kinda
outdated and slow now, but what is currently available at what
speeds/costs and how are they setup? Rather OT I suppose.
But more towards the quote above, what really would be needed to
setup a T1? And how fast IS a T1(something I probably used to know
but forgot a while ago since I don't run across them often)? The
older TSU/CSU/DSU/Whatever-SU's(not only is my memory bad, but I
can't seem to think straight right now!) seem to show up a lot at
surplus stores or in junk piles. Any reasons to grab or avoid them?

Hi
A T1 is a old telecom digital datastream consisting of 24 ds0 s
A ds0 is a 8 Kbyte serial data stream, ( one simplex audio stream )
so, a T1 is 24 * 8Kbytes/sec = 196.5Kbytes/sec, about 1.5kbits/sec
ADSL or cable are much cheaper and faster, T1 is externally clocked
and will not be blocked, if you are sending continuous data, and the
application requires a unbroken datastream, T1 is the economy way
to go. For any packet traffic it's a waste since your paying for every
bit.

oops, i ment about 1.5 Megabits/sec

The only use for such devices would be to create a point-to-point T1
connection between two structures where the distance between them is too
for for a standard 10/100baeT cable run. In that case, you would also
need routers on each end that have a T1 interface.
It would be fun to play with if you can gather up all the necessary
equipment.
