Very few people want to remain anonymous when calling a residence.
But since we're talking aboud Calling Number ID, anonymity has little
to do with it. It doesn't ID the caller, it IDs the line from which
the call is placed. Can you really say that you never, ever, make a
call when it's none of the callee's business where you're calling
from?
The standard example is a doctor whose answering service screens the
calls but returns patients' calls from home when they call evenings
and weekends.
Or you're a lawyer or consultant visiting client A, and you use the
phone to call client B to let them know you're coming over.

The very last time I had contact with my doctor was a time when I had
suddenly gotten very sick with an infected chest. His office said he
had left for the weekend; I expressed an urgency about reaching him,
and they contacted him. Had he not called me from home, he wouldn't
have had time to make his plane.
Now, as it happens, he doesn't particularly care whether people do get
his phone number through CNID. But in this particular situation, if
he _did_ care, I would have ended up with a $300 emergency room bill
instead of the $8 pharmacy bill under the originally proposed
scenario, since he wouldn't have been able to block CNID delivery
under it.

Sure. There are lots of muxing techniques. Probably you'd run a
single T3 and dedicate 10 Meg to the data, and the other 35meg to
voice, giving you about 350 phone lines. But, the equipment to do
that will cost much more than the cost of the copper cable ...
On the other hand, if you just add two more pairs of fiber, you can
run a T3 or even an OC-3 between your PBX's. If you make one a master
and the other a slave, you can link them together as a single
manageable unit. The cost of adding a couple of fibers, and
eliminating a copper cable with all of the lightning protectors and
tails, blocks, installation, etc, will probably come out low enough to
be able to afford a couple of fiber cards for your PBX with enough
change to afford a couple of real fiber bridges (please write for
recommendations as to brands - I'd need more information as to your
needs).
