Explanation Of A Fone System Written By Darkness What to expect in this article!! I will describe the termination, wiring, and terminal hardware used the most in Bell's system. I am not responsible for anything you do with this information! So if you want to be a dumb shit, go ahead but leave me out. LOCAL NETWORK The local telephone network between the central office/exchange and the telephone subscribers goes like this!! From the central office of a certin prefix, underground area trunks go to each area that has a prefix. Once every few blocks or streets the underground lines come up!! Then they run up a telephone pole, or back underground depending on the city, than they go to your house, or business. If they go somewhere with multilines then they have to go through a distribution box or panel. UNDERGROUND CABLES Sometimes called inter-office trunks, but usally in a residential area they are trunk lines that goto bridging heads or distribution cases. The cables are 2-3 inches think and are usally in a metal or pvc-pipe casings. Usally the cables are never alone in the ground. Instead they are usally in an underground cement tunnel (this is why I like that crowbar sooo much). The manholes can be opened with your crowbar, there is a little ladder inside to help you climb in and start your adventure. When you get in you will see cable pipes on the wall the blue and white one is the inter-office trunk. The others are local lines, and are usally marked or color coded. There is usally a color code chart on the wall, and also Telco manuals to describe cables and termainls, so help yourself to some of this cool shit!! I sure as hell did. BRIDGING HEADS These are the gray or green boxes. These can be either trunk bridges or bridging for homes. The major trunk bridging heads are usally larger, and they have the "Western Electric" logo at the bottom, the normal bridging heads have the local fone company, like where I live it's U.S WEST. Ok now how to open a bridging head. If its locked and u wanna be like me pull out your crowbar, and put it in the slot above the top hinge of the right door, that bastard should rip off, if it doesn't just beat the shit out of it with a sledge hammer. Now if it isn't locked take a 7/8 inch hex socket and turn the bolt 1/8 of a turn to the right, u should now hear a little pop, thats the spring realsing, now turn the handel all the way to the left, and then pull it out!! Now that your in check for a test set, usally their not there, but sometimes they are. If their not, then just grab your own, remember I tought u how to make one in my first text, now u can have free calls to everyone!! hehehe! Now there should be a panel of terminals and wires. Push the panel back an inch and turn the latch on the top, now the whole panel should fall forward, there usally is a shitload of extra wire back there, sometimes there are extra test-sets back there, you can help yourself to some!! Lots of times there are manuals back there also, take some, there good reading while your on the shitter. On the doors there are 2 round metal things, and on the front of them there are two terminals, this is for your beige box or test-set. I showed you how to make a beige box in my first text titled "The Novice Phreaker". Now hook your tip wire to the + terminal, and your ring wire to the -. Or just remember ring=red, green=tip. Behind the metal disc is a rolled up cord, with usally two alligator clips on it, this is nice because you don't have to keep disconnecting and connecting the beige box. On the terminal board there should be 10 screw terminals per side. Follow the wires, and you can see which cable pairs are active.Hook the clips to the terminal pair, and your ready to make some free calls, or you could just listen in on someones fone calls and say some very funny shit to them. On major prefix-area bridging heads, you can see 'local loops' which are two cable pairs that are directly connected to each other on the terminal board. The loops don't work nearly as well as the ones in the switching hardware at the exchange office. Ok now you should try scanning your prefixes 00xx to 99xx #'s. The tone sides will announce themselves with the 1008 hz loop tone, and the hang side will give no response. The first person should dial the 'hang' side and the other person dial the tone side. To find the number of the loop that you are on use ANI. ANI AUTOMATIC NUMBER ID This is the Telco test number that reports to you the number from which you are dialing from. For the 213 NPA - Dial 1223 408 NPA - Dial 760 914 NPA - Dial 990 These are extremely useful when messing with any kind of line terminals, house boxes, etc. We now have the bridging heads wired, no we can move on, close up all the shit you have opened, unless you want Telco to catch on. CANS TELEPHONE DISTRIBUTION BOXES There are usally only two types of these boxes. The first one is a large rectangular, sliverish or greenish box on the each street. The second one is black and round or rectangular box at every telephone pole. The first one is the case that takes the underground cable from the bridge and runs it to the telephone pole. The box is always on the pole nearest to the bridging head where the line comes up. These usally have two rows of terminal sets. The second one is the splitter box for the group of houses around the pole. Use it like before, the terminals will be in two rows of sets, the extra wire in there is for extra lines to peoples house's. If you really want to start some trouble re-wire all of these lines to random houses!! Now that would be funny as fuck. MULTILINE DISTRIBUTION BOXES These are for apartments or businesses with many lines running through it. The boxes are found outside the buildings, on the right side or in the basement. This box will have all the terminals for all of the lines in the building. Use this box the same as we did the others, it can have up to 20 terminals in it, forget the middle terminals these are the grounds. The ring is usally the top terminal, and the tip is in the clap/screw below it. This can be reversed, but the cable pair is always on top of each other, not next to it. As an added help,here is the basic 'standard' color-code for 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. You can also tap into this box with your beige and make free calls out of here. Or if your pissed at the owners of this box you can just cut out all of the wiring in here, and they won't have a fone for a while. Well I hope you people have learned something from this!! You can now make all the free calls u want, or just fuck with your negibors heads!! I'm in no way responsible for what u do with this info., if u get caught it your own ass. Lemme give shoutouts to some of my phreaking phreinds, N0de, Phantasm, InfinityMatrix, EF, and Plex!! Keep up all the good work guys!!
