Radio Shack sells a box which plugs into a phone jack and supplies a
HOLD capability. When you want to put a call on HOLD, you double-click
the phone, listen for the squeak which means that the box is active,
then hang up. You can pick up the call from any instrument on the
line, or if you do nothing for six minutes the line will be
disconnected. The box includes a wall-bug which you have to plug into
a 115VAC outlet, and the bug buzzes, but since you never have to touch
the box you can install it in, for example, the garage.

My understanding is that anything that crosses a public road or railroad
is ipso facto within the jurisdiction of the tarrifed telco.
Conversely, if your wires /don't\ cross a public road or railroad, then
anything you do is your own business, (subject to laws of tresspass,
etc). The terms "public road" and "railroad" have precise legal
definitions, and all this is as per Federal Communications Act.
Correct me if I'm mistaken, anybody.
If you cross the road with a wire, the city (and the State) certainly
has the right to make rules about what can use public rights of way.
(That's how cities get away with regulating cable companies but not
Satellite Master Antenna Systems for apartments). In many States the
telephone company has an exlusive franchise to use the roads to run
wires for the purpose of offering COMMON CARRIER telecommunications
services. The key phrase here is common carrier. If Citibank runs a
fiber from their midtown to downtown offices (which they have done) the
telephone company can't complain because the fiber is being used for
intracompany communications. Only if Citibank started selling excess
capacity on the fiber to anyone who wanted communications service (i.e.
acted like a common carrier) would their be a possibility of regulation.
The New York Teleport will use fibers to connect users to a satellite
dish farm being built on Staten Island. The Teleport will not be
regulated as a common carrier however, because each user will own his
own fiber from Staten Island to his premises in Manhattan.

I'm having trouble making the following message wend it's way to
Richard Outerbridge, so I hope you will indulge my taking the graffito approach:
Dear Richard Outerbridge:
Thanks very much- your message containing
sources for voice scrambler info was exactly what I was hoping for.
Unfortunately both books are for the moment unavailable from the
UC Berkeley library (one possibly filched, the other in use).
After my tantalizing and disappointing afternoon at the library,
I'd be very grateful for any brief summary you could provide.
By the way, what does a "verifier" at a phototypsetting firm do?
(the only stuff the library *did* have was most of Cryptologia.)
In happy anticipation,
Doug Maisel

That's odd. Before we had an ESS exchange dialing yourself gave you
a busy signal. After ESS, you got a tape recording telling you "your
number could not be completed as dialed," although it might as well
have said "you can't call yourself, stupid." In both cases, trying
to user 1+ on any local call caused a "your call can't be completed
as dialed." Although, recently I've heard "You do not need to dial
one first."

Of course the problme with the radio station on the modem could be
some poor design inside the modem, causing the modem to become a
poor AM receiver. I used to have the same problem with my stereo
when I lived two blocks from an AM radio station.
