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 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 terminal. Now take a 10k hm 1/2 watt 10% resistor and put it between the terminal ad the terminal, which should have a blue and a white wire going to it (different for touch tone). It should look like this: -----Blue wire---------- ! ----White wire-----! ! 10k Resistor ! ! --Green wire-- !---- ! ! 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 Continued In: Ma Bell Part II
