|
||
Underground telephone networking done by Bell is fascinating stuff and fairly
|
||
easy to gain access to. If you know what you're doing, you can accomplish
|
||
alot, learn alot, and take home some stuff to play with.

||
Getting Underground
|
||
~~~~~~~~~~~~~~~~~~~
|
||
First, you will need to find one of those Bell manholes. They are VERY heavy
|
||
and say "Bell System" on them. In the country, they are harder to find than
|
||
in cities and suburbs. Look on the paved main roads and you will probably
|
||
find some. They have a little square hole in the middle which is how you
|
||
will getting inside. Stick the hook side of a crowbar in the hole and push
|
||
down. When the lid lifts, grab it and roll it onto the street or sidewalk.
|
||
It is best to do this at night because it is obviously *very* easy to get
|
||
caught doing this. Before you stick your feet in, look for the ladder rungs!
|
||
The drop is 6-10 feet if you fall, and it can get very damp and slippery down
|
||
there! If you're new at this, leave the lid half-open (never completely!)
|
||
and also bring a friend: if one of you gets hurt, they can always run home
|
||
and get help. Also, bring a flash light so you can see what the hell you're
|
||
doing until you find the light. If you can get one of those mining helmets
|
||
with the light on it, use it.
|
||
|
||
What You Should See
|
||
~~~~~~~~~~~~~~~~~~~
|
||
There will be a small room at the bottom which sometimes has tunnels. There
|
||
will be all kinds of telephone equipment down there, and sometimes even a
|
||
computer which is connected to a humungous network. There will also be
|
||
pipes on the walls that have cables running through them. Each one will say
|
||
what's going through it, or be color coded. There is often a chart on the
|
||
wall.
|
||
|
||
Dull Green Boxes: Opening
|
||
~~~~~~~~~~~~~~~~~~~~~~~~~
|
||
These things are called bridging heads and each one has as many as 1200 cable
|
||
pairs inside! There are many different varieties of these with different
|
||
levels of function in the network, but most are made by Western Electric or
|
||
GTE, and these are the ones I will be discussing. The larger Western
|
||
Electric ones with the WE logo on the bottom feed the whole area. The normal
|
||
bridging heads, which are smaller and often made by GTE, are usually bridging
|
||
for homes and individual buildings.
|
||
These things are tons of fun to play with. If it's locked, stick your crow-
|
||
bar in the slot above the top hinge on the right door. If you pull nice and
|
||
hard, the door will rip right off. If it isn't locked, take a 7/16th inch
|
||
hex socket and turn the bolt s-l-o-w-l-y to the left until you hear like a
|
||
little pop. Hold onto the bolt and turn the handle all the way top the right
|
||
and pull it out (toward you).
|
||
|
||
Bridging Heads: Getting Behind the Panel
|
||
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
||
Once you've opened a bridging head, look around for the test set. This is
|
||
like the handset to your phone, except it doesn't have a phone attached to
|
||
it. You will see a whole panel of shit (all of the little cable pairs and
|
||
lots of little metal screws) which you should push back about an inch. Then
|
||
rotate the latch on the top (which is round with a little shaved-off flat
|
||
section) downward. Then let go of the panel and it will fall forward. If
|
||
you didn't see a test set before, there is probably more than one here!
|
||
There will also be lots of extra wire and metal screws (like the ones on the
|
||
panel).
|
||
|
||
What to Take from the Bridging Head
|
||
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
||
Here is what to take from inside the bridging head. Some of it will be
|
||
needed later, and some of it is just good to have around.
|
||
<20> Take at least one test set (pick up some for your friends).
|
||
<20> Take the 400 foot rolls of #22 wire usually way in the back of the box.
|
||
<20> Take lots of insulators, binders, clips, and those little metal screws.
|
||
<20> Take the little black box with buttons on it (the line crossover).
|
||
|
||
Stuff With Your Test Set
|
||
~~~~~~~~~~~~~~~~~~~~~~~~
|
||
On each door, there is a round metal thing that says "Insert Gently" or
|
||
"Clamp Gently" or "Do Not Overtighten" or something like that. On it are
|
||
two terminals which you will use with your test set. Hook the ring (-) on
|
||
your test set to the "R" terminal on the metal thing, and the tip (+) to the
|
||
other terminal. Now lift the terminal board (the thing that fell forward).
|
||
There should be about 20 wire pairs (red and white) on each row (the same
|
||
thing is on the back). Behind the metal disc is a coiled up cord with a
|
||
special connector on the end of it. This is very useful: you don't have to
|
||
keep on connecting and disconnecting your test set; you just clamp on the
|
||
connector. Now hook the clip onto any terminal pair....
|
||
|
||
Once You're Connected to a Terminal Pair
|
||
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
||
Once you've connected your test set to a terminal pair, you can hear
|
||
whatever's going on on that line. If you get a conversation, you can listen
|
||
in on it, but be careful because they can hear you! A fun thing to do is to
|
||
play the operator and tell them that there's an emergency call for someone.
|
||
If you get data, there's probably a way to hook it up to any computer that
|
||
happens to be down there, however there don't seem to be any provisions for
|
||
doing this. If you get a dial tone, you can have lots of fun. Call a friend
|
||
and tell them what you're doing. Call someone long distance that you haven't
|
||
seen in ten years. The best thing to do is make harassing calls to the
|
||
operator, and when they trace the number and call it back, they'll be calling
|
||
the people whose phone you're using! You can listen in on the whole thing.
|
||
|
||
Whose Phone Are You On?!
|
||
~~~~~~~~~~~~~~~~~~~~~~~~
|
||
There is something called a Bridging Log in the box which you can try to
|
||
decipher in order to find out what number you're on. An easier way is to use
|
||
a special test number. For the 213 NPA, dial 1223; for 213 (GTE areas), dial
|
||
114; for 408, dial 760; and for 914, dial 990. Sorry, those are all that I
|
||
have, but you may be able to find a chart in the box.
|
||
|
||
The Little Black Box (Line Crossover)
|
||
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
||
This thing is used for testing lines. Hook your test set up to it and then
|
||
dial any local number. When you have finished dialing, press the button on
|
||
the box labeled "ON LINE" and you will hear their conversation. This is an
|
||
even easier way to tap a line.
|
||
|
||
Tapping from Your Home: Finding the Dude's Line
|
||
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
||
Look up the number of the dude whose phone you want to tap. Have a friend
|
||
call him and give him some long poll (have him say he's from Gallup: most
|
||
people will stay on the line). Find out exactly what your friend's going to
|
||
say. Then go to one of the manholes and clip your test set onto every line
|
||
and listen for a second. When you hear your friend, you have the right line.
|
||
To find your line, take the phone off the hook and leave some music playing
|
||
nice and loud in your room. Then repeat the above process listening for the
|
||
music. Mark the two sets of contacts (the dude's and yours).
|
||
|
||
Tapping from Your Home: Connecting His Line to Yours
|
||
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
||
Take two lengths of thin wire (one red and one white). Loosen the screw
|
||
holding his red wire and the one holding yours. Take the red wire you cut
|
||
and wire it from his red-wire screw to yours. Then repeat the process for
|
||
the white wires. Now nip the two wires (one red and one white) that
|
||
originally led to your line. Congratulations! You are now sharing his line!
|
||
|
||
Tapping from Your Home: Listening In
|
||
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
||
I suggest that you do the above stuff with a seperate line, because it
|
||
completely destroys your line. The best thing is to get a speaker phone with
|
||
those little red and green lights that tell you if someone's on the line or
|
||
not. When the red light goes on, he's on the line. Turn on your speaker
|
||
phone or pick up your phone and you can hear him! Unfortunately, it works
|
||
both ways: he can hear you. The best thing is to get one of those old
|
||
external speaker phones with a mute button that STAYS IN when you push it.
|
||
You will also be able to make calls with his line.
|
||
|
||
Hacking Their Computers
|
||
~~~~~~~~~~~~~~~~~~~~~~~
|
||
EVERYTHING on the computers they leave down there is password protected. If
|
||
you are able to get in, there is all kinds of stuff in there. Artman [SiC]
|
||
said that he would be releasing his codes for the Bell System computers soon,
|
||
however I have never seen this file. Please let me know if you get any
|
||
codes.
|
||
|
||
The Tunnels
|
||
~~~~~~~~~~~
|
||
Phucked Agent says that there are sometimes tunnels down there. I personally
|
||
have never come accross any, but if you see some, go into them! There is
|
||
probably some really cool stuff in there and they are probably passage ways
|
||
to other rooms. Tell me what you find if you go through one!
|
||
|
||
Leaving the Man Hole
|
||
~~~~~~~~~~~~~~~~~~~~
|
||
Always put everything back very neatly before you leave. Also, never take
|
||
too much stuff at a time. If they notice that a great quantity of stuff is
|
||
gone, they may be more careful in the future.
|
||
|
||
Please Let Me Know
|
||
~~~~~~~~~~~~~~~~~~
|
||
Please let me know how successful your hack of Bell has been. I live in 516
|
||
and can be reached on many elite boards there.
