Does this mean that you will be able to dial the same 800 number on
MCI, Sprint, Etc., and preface it with a five-digit access code once
the seven-digit lookup for 800 numbers takes effect?

[Moderator's Note: No. You will never be able to decide which carrier
will handle the call you place on anyone else's 800 number. By virtue
of them paying for the call, they make the decision which carrier will
be used. What will happen is that owners of 800 numbers will be able
to switch carriers while keeping the same 800 number, something they
cannot do now. People calling an 800 number will continue to dial it
as always: the LD carrier or local telco on the originating line will
have nothing to do with it; the local telco will see the number dialed
and hand it off to the appropriate carrier for processing.  PAT]

This is a little off of the videotelephone question, but: Video
Jukebox Network uses 900 numbers in conjunction with cable tv
broadcast to allow subscribers to order music videos using a 900
number.  Conceivably, other video services could be offered as well.

What I want to know is how they make sure that only the person who

Unless the things have changed since I installed OSP fiber a few years
ago you wouldn't see anything.  Virtually all fiber operates at one of
a few wavelengths such as 850 or 1300 nm.  If I remember these
wavelengths are all below that of visable light.  Otherwise you could
see the light if you were near the transmitter, despite the low power
levels, as the output is very coherent. I tried to look up these
wavelengths in my CRC and a physics text but they didn't list the
range of visable light.  I am almost posative these are IR though.
 
Cutting the fiber is a chore in itself as most OSP cable uses steel
tension members embedded in the jacket while the fibers are in a
buffer tube.  You generaly need cutters designed for ACSR power cable
to cut it.  When doing some blasting, I droped a 60lb rock on top of
some fiber after it fell about 40'.  The fiber was supposed to be
protected by split pipe, but someone with the telco had failed to do
their job. The fiber was undamaged though.
 
OB MCI story: A few years ago I was installing fiber for MCI along
side of a Union Pacific Railroad ROW.  We had a rather sharp civil
engineer from MCI supervising the installation as well as a splicing
tech just in case.  The tech and I were trying to explain loss budgets
to the CE, as he couldn't understand why the repeaters had to be so
close together.  He finally thought he understood and came up with a
solution: If we could increase the power from 30 dbm (an example
figure we gave him) to 90 dbm we could double the spacing of the
repeaters by increasing the power 300%.  90 dbm is of course not three
watts, but one megawatt!!  I thought this would prove a real deterent
to cutting the cable.  Got a cable cut?  No need for a OTDR, just look
for the smoldering backhoe :-)
 
Seriously, fiber technology is changing fast.  In the future look to
see photonic switches, erbium amplifiers, and a few other twists.  The
ISDN guys, after using 2B1Q to get bidirectional data transmission on
a twisted pair loop, are now looking at running bidirectional BISDN
links over a single fiber using two frequency bands, much as is done
with CATV.  (Don't know if they would like that analogy.)

The August 14 edition of Yerushalaim (a Jerusalem local newspaper)
contains a copy of a letter that Bezeq, the Israeli telco, mailed to a
phone booth which it owns.

The form letter is addressed to "Bezeq, Inc." at the address at which
the phone booth is located (155 Costa Rica Street), and informs the
subscriber that while in the past, its bill was computed by reading a
meter, which made it impossible to obtain a listing of calls made,
this will now be possible (at a fee, of course, something that Bezeq
did not mention to the phone booth).

The letter-carrier delivered the letter by placing it inside the phone
booth.

Bezeq responded that the program that sends out mailings will be
corrected.  The phone booth was unavailable for comment.

I recently acquired two synchronous astrocom modems from a junk sale.
They are blue boxes, 9"wide x 11"long x ~2"high. From the switches
on the front panel, I can switch from 2.4 up to 19.2 Kbps. There is
analog / digital mode switch too.  There are four screws at the back
marked Receive tip/ring and Transmit tip/ring.

The label at the back reads: 
	Astrocom Corp.
	ST PAUL  MINNESOTA
	DESC. MOS/2

1.  I presume speed of xmission using these modems is inversely
related to distance. Therefore going thru a SWBell phone connection
may not be a good idea since the path to the CO and back may be miles.
Is this a correct assumption?

[The answer to the next question may be in an FAQ list, but I cannot
find the FAQ list. ;(]

2. Does anyone know how I can hook these up to talk between two remote
PCs? Since these are synchronous modems. I know it will be a pain not
having the ability to dial, etc. But just as a thought, how difficult
would it be to get one of these to talk to another asynch modem? In
order to save bandwidth please send me direct response and if it's
okay with Pat and I get enough responses I'll summarize later.

I moved into a new apartment this weekend, and found a mysterious box
plugged into an electric outlet, with wires running into a telephone
junction box.  Various writing on the box reads:

    Western Electric
    2012C  Trnsf.

    PRI: 105-125V  60Hz
    4.7 VA MAX
    
    SEC: 6-8V   1.75 VA

        CAUTION
     INDOOR USE ONLY

    UL Listed Class 2
    786D Trnsf.

OK, it's some kind of electric transformer.  But what is it for, and
why is it there?

I unplugged it from the wall and unscrewed the wires in the junction
box, my phone service seems unaffected.  All of the phones still have
dial tone, all of them still ring.

I called New England Telephone, but neither the Business Office nor
the Repair Service knew anything about it.  One person suggested that
it was a step-up transformer that was needed to power a Princess phone
with lighted dial.  But I have an AT&T Trimline phone, and its dial
still lights up just fine without the transformer plugged in.

Anyone know more?


Ron Newman	rnewman@bbn.com


[Moderator's Note: It is indeed a transformer to light the dial on a
Princess phone ... a style long since replaced by the Trimline models.
The reason you do not need it on the Trimline is because instead of an
actual little light bulb under the case of a Princess phone, the newer
Trimline model uses LED's under each push button and they light up
from line voltage, eliminating the need for an external source of
power to light the dial. On the old Princess models, the light, being
independently powered from the transformer you have via the second
pair of wires in the cord to the phone did not go out when you punched
the buttons as it does with the newer Trimlines when you momentarily
steal the voltage to send tone signals. Did you ever see a *two line*
Princess phone with a turn-button to select the line? It had four
pairs of wires coming in: one pair for each line, one pair to
illuminate the flashlight size light bulb, and a fourth pair to handle
the momentary press down/release turn button to signal another station
when one line was used as an intercom. Talk about a mess of wires
inside the little tiny plastic housing!   PAT]

In Washington and Oregon, you had to specifically *request*
touch-tone.  A few years ago US West filed to drop the charge and make
touch tone service universal on their lines in Oregon. I believe they
did something similar in Washington.

The best thing you could do was to unplug it. Those little
transformers were responsible for starting many fires. People would
plug non-lighted-dial phone into the outlets and sometimes the
transformer secondary would be shorted. These transformers have no
thermal or over-current protection, so the frequent result was a nice
cozy fire.

All four-wire WE bells with the colors Black, Slate/Red, Red, Slate
(where slate means grey) are/can be connected as follows:

Put a 0.5 microfarad non-polarized capacitor rated at at least 200
Volts between the Slate and Slate/Red (available from Radio Shack or
an old phone.)  Connect the other two wires to the phone line.

Inside a phone, the Slate and Slate/Red are connected to "A" and "K"
on the block/circuit board, which are just the ends of a capacitor and
don't connect to anything else.  The Red and Black connect to Tip
(Green - L1) and Ring (Red - L2) of the phone line.

I may have some of my polarities backwards, but it will all work
either way.  None of this applies to party lines.  The bell is NOT
normally disconnected from the line by the hookswitch -- it's always
connected to the line.

There are essentially two windings in the bell which you are
connecting in series with the capacitor in between the two.  I
understand that the purpose is to allow rewireability for party line
ringing.

Hope this is the type of bell you have -- I believe the big black old
outdoor ones only have two wires to the bell windings, so you just put
the capacitor in series with it.  I still don't know what the blue
wire is for on the Trimline bells, but they can also be wired as above
with the blue wire left unconnected and insulated.

You can also "tune" the individual phones by removing a different gong
from each, or putting both "A" gongs in one phone and both "B" gongs
in another, or wrapping the gong-hammer in tape or taping the gongs in
one phone so they don't resonate well.  When everyone in an office has
the same model phone you have to get creative.  Keep your fingers off
the bare wires if you're tuning while it's ringing!

After reading over the discussion over the need of a LOUD telephone
ringer, I'll tell you of our experience.

A few years ago (aprx. 1984), the business I worked for (a family
owned business) moved from a garage to a regular building. Since we
have heavy machinery making loud noises while in use, we needed a loud
ringer.

The first thing we tried was a Radio Shack outdoor ringer. No good.
Then, we tried what was originally supposed to be a flasher for the
hearing impaired, and hooked up a old burglar alarm horm. Bingo, it
worked, although from that point on, whenever we had a new person
visit the shop, we had to watch them jump as they heard that horn for
the first time.

What do you consider as interfering with normal use?  If what you want
is a telephone that doesn't ring, why not either purchase a telephone
that has a ringer off switch, or just simply cut the wire that goes to
the bell in the set you are presently using??

Okay, I'd be glad to, but I need a little more specificity before I
launch into a long-winded exposition.  Are you referring to CDMA in
general (any form of Code Division Multiple Access) such as that used
by the military, or are you specifically referring to the CDMA that
the CTIA/TIA are working on for mobile phones?  And if you mean the
latter, do you mean the CDMA-specific part of it, i.e. just the
modulation and demodulation, or are you looking for a broader system

The Antitrust suit was filed in 1974 under the Republican Ford

assigned to the case until several years after it had been filed.

As for AT&T stonewalling the antitrust case, had they done so, the
House would likely have passed the legislation that had already
cleared the Senate.  In AT&T's judgement, the legislation would have
been worse then the consent decree.  If a gun was held to the head of
AT&T, it was not by Judge Greene.
