Breaking and Entering - The Telco Way By Keltic Phr0st ===================================== ================ I think I wrote a file on this topic before, but to tell the truth, it was just too lame for words. So here I go...Rehash and Improve, with accurate info this time. Some of you may be aware of the obsession I seem to have with UXD5b GEC Plessey 600 Line switch. This is primarily because there is an abundance of them in my local area, the telco is stupid enough to leave all their trash outside the building, and they are not even visited by BT unless something radically service-threatening rears its ugly head. If you've read my file "Various BT Documents" You'll see a draft of a document I snarfed one night after a B+E spree that sets out the category and seriousness of any particular failure. This basically deals with Mega/Kilo Stream failures, H-H Xmission failure, Dialtone loss, etc.. BIG things that can go wrong, basically. Needless to say, unless its acting as a subs concentrator, there aint going to be any abundance of heavily used high capacity Trunks leaving the building. There is really only one or two things that can fuck up in a major way, and that is why I like this type so much. Theyr'e simple, theyr'e digital, they have all the advantages of System X, and none of the disadvantages such as Caller ID. (UXD's do not come equipped with the CLID unit as standard... If you recieve a call from one of these exchanges, and you have CLID, then the display just says "UNAVAILABLE"). Ok...Now down to the B+E. What you basically need is the following: 1: Black Rucksack and Impossible Mission Clothes for Trashing 2: Steel Draftsmans Ruler with Rubber Tape on one end 3: Torch 4: Gloves (VERY IMPORTANT...DUH) If you live in a rural area, and you know every building in your general locale, then you should by now be aware of which one the exchange is. It usually has Frosted reinforced windows, a blank door, concrete hatches round about, etc...More often than not, they are quite far away from residential areas and potential hazards. Ie : Look for something vaguely resembling a gas chamber in the middle of fucking nowhere. Just a word on External Security : None. Its that simple. Just walk straight up to the door. No alarms, no guard dogs, no engineers constantly in the building, no vans, no nothing. Just a flawed lock mechanism and a Fill-wood door standing between you and all the telco info you can carry. Remove your ruler, and grab the rubber end. This...is...the...grip. Have you worked out what to do with the other end yet? Look at the door. Does it resemble the following diagram? +---------------------+ | | <---- Frosted/Clear Glass +---------------------+ | | | | | | | | | # | <---- Ingersoll Lock | ! | <---- Door Handle | | | | | | | | | | |_____________________| | | <---- Sloped Panel +---------------------+ Now force the ruler into the side of the lock. Push it down and in until you can hear an audible click. You may spend some time trying to find the lock bar, but it will pop open quite amicably when forced. If you cant force the lock just by popping it...Then there is probably a wooden panel put there to stop filthy little herberts like you embarking on this sort of task. Dont give up though... In the Olden days, when exchanges were manned by a full time human operator, there used to be mail slot for the Post-bloke to pop the mail thru the door. The mail in those days was pretty dull...Just info on subscribers such as number changes, New procedures to follow, reminders of an imminent Engineer visit, reminders to check the cells... Because of the tight wad gits that run BT now, a lot of these exchanges still have the post slot on them...and its large enough to allow an arm through quite comfortably... However...A bit of metal work or dexterity is needed to get your paws in there. Take a gudgey at the following : | <---------- Door | | |------+ Mail Flap ------> \ |<---- Metal Shelf \ | | | | | The basic operation of the shelf is to foil the casual burglar. Simply take a lever orientated object ( Like...A Crowbar!! Yeah!!) and pop it in thru the mail flap. It will stop against the shelf. Simply raise it at your side until it goes under the shelf at the same angle as the flap, and pull down on the fucker until you hear the screws holding the shelf in place pop out, or the shelf bends right up. The advantage being that this leaves no external evidence of your work, and you are now -Guaranteed- entry. Simply remove the lever, pop your arm through the hole, and reach over towards the door handle. You should find a horizontal lever approx. 2 inches in length resting in your sweaty grip. Push it away from you.Ta-da!! The door is now open!! Quickly get inside and close the door. Bag the Shelf as a souvenir if its fallen off. It might take BT some time to realise that somebody has forced entry, and then get a new shelf, assuring your unhassled entry to the building until that day. If its still on, but bent beyond belief, simply push it back into shape. Its not very strong metal...Its just designed to stop a hand or nosey bastards looking in. You should now be standing in a lobby with another door in front of you, and one to your left. The door on the left is the toilet. Have a shit at BT's expense...But be warned, their Bog roll is like Tracing paper. Above the Toilet door is what looks like a burglar alarm. Correction : Its an early warning system in the event of a fire. The exchange is designed to inform the authorities if it catches fire!! It should have green leds calmly staying on all over it, and the by now familiar BT logo in grey on the case. Ignore. Proceed to open the door in front of you... ALLADINS CAVE!! Hello!! Look at all that yummy telco stuff, waiting to be snarfed!! Wanna Map? Ok.... +-------------------------#########################----------------------+ | +------------+ +------------+ +-------------------+ | | | | | A | | | | | | | +------------+ | | | | | B | | K | | | | | | | | | | | +-----+ | | | | | | | | | +------------+ +-------------+ | | | | | | | | | | | | +-----------+ | | | C | | J | | | | | | | | | | | +-----------+ | | +------------+ | | | | | | | | | I | | | | | | | | | | | | | | | +-----------+ | | | | +--+ | | | |===============| | | |===============| | H ---> | |===============| | | |===============| | | |===============| | +--+ | | +------+ | | | | | | | G | | | | | | | +------+ | +------------------------------@@@@@@@@@@-----+ | | | | | | | D | | | | #---------+ @ | | # @ | | # @ F | | | +-------+ @ | | | | E | | | | | | | | | | +--------------------------+---@@@@@@@@@@@----+----#############---------+ | | | | | | Where @@@@ = Doors A = Component Workbench #### = Windows B = Switching Cab 1 C = Switching Cab 2 D = The Sink E = The Shitter F = The Lobby G = Line Pressurisation Unit/Gauging H = Main Distribution Frame I = General Work Area J = Filing Cabinet K = Emergency Diesel Generator First thing you should always check is the General Work area. Rifle thru the drawers on the desk and then check to see if the filing cabinet is open. There should also be a waste paper basket close by...Empty that into your rucksack. If the desk drawers are open, you can find MDF Records for your entire exchange, Work permit forms, BT Pens(!) Carrier allocation cards, Work pending sheets and all sorts of other assorted BT Excretia which they would -rather- you didnt have access to. The MDF Records are the best, cause they list all the numbers in your exchange, what they are, If they share any pairs with any other numbers...They also list ALL test numbers, Loops, Operator Sub-System Dial-ins, OG/IC Trunk pairs, Basically, every pair currently allocated within the exchange. This is without a doubt, one of the most accurate "scans" you're gonna get, so pocket these immediately. Now make your way over to the MDF (Main distribution Frame). Now is your chance to see if the bastards are REALLY tapping your line. Refer to your MDF record, and look up your DN (Directory Number). It should also have an EN (Equipment Number) and the pair it has been allocated, usually just entitled 'number'. Look at the frame. See all the wires? Thats where all the subscribers lines leave and enter the building. Look up your pair... Its quite easy, becuase all the wires are labelled on the frame bars... Found it? Can you see any 'supplementary' Jumpers or wires connected to it? You can? Good lord. How simply unspeakable. Invading peoples privacy like that!! If you came tooled up PROPERLY, you'd have your test set out now, and be clipping onto every available pair to listen in and dial out. Stop now, and pay attention to your pair. Clip onto it. Got a dial tone? Good. Now clip onto the supplementary pair if its there. Silence? Snip the bastard. Make it a good job, so it looks like an engineer messed up (Try clipping it really deep into the frame, right next to the connection point) and forgot to reconnect it. Now, just to make sure you havent disconnected yourself, pick up the phone on the general work area. Dial your number. Ringing? Excellent. Hang up. DONT let it connect, or the call will be registered and cross registered with engineer visits. If they find out someone has dialled out of the exchange when an engineer wasnt present, questions will indeed be asked, and there will be tears before bedtime. Now, dirty work and back covering done, take a sniff around. Ignore The diesel Generator and the Pressure unit...Take my word for it...They're DULL articles just put there to annoy the ardent burglar. They are also EXTREMELY DANGEROUS and LIFE THREATENING To mess around with. Observe the WARNING!!! Logos splashed all over them. Next...Switching Cabs! Cabinet one should look like this : -----+------------------------------------------+ | | | | +------------------------------------------+ | | | ######## ######## ######## | | ######## ######## ######## | |------------------------------------------| | | | +--------------+ | | | @@@@@@@@@@@@ | | | | @@@@@@@@@@@@ | | | | @@@@@@@@@@@@ | | | +--------------+ | | | | | | +--------------+ | | / ::::::::::::: \ | +------------------------------------------+ | | | +----------------+| | | || | | || | | || | +----------------+| | | -----+------------------------------------------+ The articles composed of ####'s in the top of the rack are BT Standard issue 2422 Modems, 2400bps. Used for Decibel loss testing, External Module Interfacing and External Dial-in access. Usually there is just one in the rack, and they arent worth nicking. They're crap. Besides which, if the vaguely terminal like ASCII below it is present, then they will need to be there if you want to actually gain access to the switch. The Terminal is the CSS Terminal, and is used to allow On the spot and remote diagnostics via the keyboard/modem/whatever, and to allow interpretation of the messages thrown back by the switch. Im not about to go into the CSS Terminal in depth here...Its a file in its own right, and Im still researching it. If its there, you can get in externally. End of Story. The vague square in the bottom right is a printer. This provides hard copy of all the switch's activities, and any repair/Diagnostics that may be in operation at the time. Tear off the Reams of paper spilling out of it, and bag them. You'll need them if you want to learn more about how the UXD unit handles basic procedures and diagnostics. The paper is that shitty fax paper, so remember to keep it out of the sunlight. Cabinet Two should just be a big blank cabinet. Its in here that all the switching and call handling takes place. Open the cabinet, and take ALL the documents sitting in the dockets inside the doors. Take the key that should be hanging there as well. This is the key for the building, and wont be missed. Stay a while and watch the switch. Look at the flashing lights. Marvel at the wonders of digital telephony. Nick an unused rack module as a souvenir. You should by now be ready to get the fuck out of the building and home to rifle thru your booty. Before you go...Take a visit to the Component Assembly Workbench. See that Glass display cabinet full of components above the desk? Take some for good measure. I was lucky enough to get a DSP one time. Now walk towards the door...Halt! Look at all the Documents and information on the noticeboard and door back! Steal it ALL! Into the bag, you know the drill. NOW leave. Make sure no-one sees you leaving. Now go home and rifle thru all your swag. Im sure you dont need a T-File to tell you what to do with the info you've blagged, but if you do, mail me on P80, 1066 or UABBS for help or details. So long, and happy hunting.
