                  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
