How Ma Bell Works - Part II

"CANS" - Telephone Distribution Boxes
|
|
-------------------------------------
|
|
|
|
Basically, two types:
|
|
|
|
1> Large, rectangular silver box at the end of each street.
|
|
|
|
2> Black, round, or rectangular thing at every telephone pole.
|
|
|
|
Type 1 - This is the case that takes the underground cable from
|
|
the bridge and runs it to the telephone pole cable (The lowest,
|
|
largest one on the telephone pole.) The box is always on the
|
|
pole nearest the briging head, where the line comes up. Look for
|
|
the 'Call before you Dig - Underground cable' stickers..
|
|
|
|
The case box is hinged, so if you want to climb the pole,
|
|
you can open it with no problems. These usually have 2 rows of
|
|
terminal sets.
|
|
|
|
You could try to impersonate a Telco technician and report
|
|
the number as 'new active' (giving a fake name and fake report,
|
|
etc.) I dont recommend this, and it probably won't (almost
|
|
positively won't) work, but this is basically what Telco linemen
|
|
do).
|
|
|
|
Type 2 - This is the splitter box for the group of houses around
|
|
the pole (Usually 4 or 5 houses). Use it like I mentioned
|
|
before. The terminals (8 or so) will be in 2 horizontal rows of
|
|
sets. The extra wires that are just 'hanging there' are
|
|
provisions for extra lines to residences (1 extra line per house,
|
|
thats why the insane charge for line #3!) If its the box for
|
|
your house also, have fun and swap lines with your neighbor!
|
|
'Piggyback' them and wreak havoc on the neighborhood (It's
|
|
eavesdropping time...) Again, I don't recommend this, and its
|
|
difficult to do it correctly. Moving right along...

APARTMENT / BUSINESS MULTILINE

DISTRIBUTION BOXES
|
|
------------------------------
|
|
|
|
Found outside the buliding (most often on the right side,
|
|
but not always... Just follow the wire from the telephone pole)
|
|
or in the basement. It has a terminal for all the lines in the
|
|
building. Use it just like any other termination box as before.
|
|
Usually says 'Bell system' or similar. Has up to 20 terminals on
|
|
it (usually.) the middle ones are grounds (forget these). The
|
|
wires come from the cable to one row (usually the left one), with
|
|
the other row of terminals for the other row of terminals for the
|
|
building fone wire pairs. The ring (-) wire is usually the top
|
|
terminal if the set in the row (1 of 10 or more), and the tip is
|
|
in the clamp/screw below it. This can be reversed, but the cable
|
|
pair is always terminated one-on-top-of-each- other, not on the
|
|
one next to it. (I'm not sure why the other one is there,
|
|
probably as aprovision for extra lines) Don't use it though, it
|
|
is usually to close to the other terminals, and in my experiences
|
|
you get a noisy connection.
|
|
|
|
Final note: Almost every apartment, business, hotel, or anywhere
|
|
there is more than 2 lines this termination lines this
|
|
termination method is used. If you can master this type, you can
|
|
be in control of many things... Look around in your area for a
|
|
building that uses this type, and practice hooking up to the
|
|
line, etc.
|
|
|
|
As an added help,here is the basic 'standard' color-code fo
|
|
multiline terminals/wiring/etc...
|
|
|
|
Single line: Red = Ring
|
|
Green = Tip
|
|
Yellow = Ground *
|
|
|
|
* (Connected to the ringer coil in individual and bridged
|
|
ringer phones (Bell only) Usually connected to the green
|
|
(Tip)
|
|
|
|
Ring (-) = Red
|
|
White/Red Stripe
|
|
Brown
|
|
White/Orange Stripe
|
|
Black/Yellow Stripe
|
|
|
|
Tip (+) = Green (Sometimes
|
|
yellow, see above.)
|
|
White/Green Stripe
|
|
White/Blue Stripe
|

Black/White Stripe

RESIDENCE TERMINAL BOX
|
|
----------------------
|
|
|
|
Small, gray (can be either a rubber (Pacific Telephone) or hard
|
|
plastic (AT & T) housing deal that connects the cable pair from
|
|
the splitter box (See type 2, above) on the pole to your house
|
|
wiring. Only 2 (or 4, the 2 top terminals are hooked in parallel
|
|
with the same line) terminals, and is very easy to use. This can
|
|
be used to add more lines to your house or add an external line
|
|
outside the house.

TEST SETS

|
|
|
Well, now you can consider yourself a minor expert on the
|
|
terminals and wiring of the local telephone network. Now you can
|
|
apply it to whatever you want to do.. Here's another helpful
|
|
item:
|
|
|
|
How to make a Basic Test-Set and how to use it to dial out,
|
|
eavsdrop, or seriously tap and record line activity.
|
|
|
|
These are the (usually) orange hand set fones used by Telco
|
|
technicians to test lines. To make a very simple one, take any
|
|
Bell (or other, but I recommend a good Bell fone like a princess
|
|
or a trimline. gte flip fones work excllently, though..) fone and
|
|
follow the instructions below.
|
|
|
|
Note: A 'black box' type fone mod will let you tap into their
|
|
line, and with the box o, it's as if you werent there. they can
|
|
recieve calls and dial out, and you can be listening the whole
|
|
time! very useful. With the box off, you have a normal fone test
|
|
set.
|
|
|
|
Instructions:
|
|
|
|
A basic black box works well with good results. Take the cover
|
|
off the fone to expose the network box (Bell type fones only).
|
|
The <RR> terminal should have a green wire going to it (orange or
|
|
different if touch tone - doesnt matter, its the same thing).
|
|
Disconnect the wire and connect it to one pole of an SPST switch.
|
|
Connect a piece of wire to the other pole of the switch and
|
|
connect it to the <RR> terminal. Now take a 10k hm 1/2 watt 10%
|
|
resistor and put it between the <RR> terminal ad the <F>
|
|
terminal, which should have a blue and a white wire going to it
|
|
(different for touch tone). It should look like this:
|
|
|
|
|
|
-----Blue wire----------<F>
|
|
!
|
|
----White wire-----!
|
|
!
|
|
10k Resistor
|
|
!
|
|
!
|
|
--Green wire-- !----<RR>
|
|
! !
|
|
SPST
|
|
|
|
|
|
What this does in effect is keep the hookswitch / dial pulse
|
|
switch (F to RR loop) open while holding the line high with the
|
|
resistor. This gives the same voltage effect as if the fone was
|
|
'on-hook', while the 10k ohms holds the voltage right above the
|
|
'off hook' threshold (around 22 volts or so, as compared to 15-17
|
|
or normal off hook 48 volts for normal 'on-hook'), giving
