- 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
- Blue
- Black/White Stripe
-
- Ground = Black
- Yellow
-
- ----------------------
- 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
