Art-WHIU ISSV-nT-W-.mSl ' VOLUME ONE, NUMBER ELEVEN Exploring Caves in Travelnet One fine summer day several years ago, a phone phreaJt discovered yet anot her i ntencsti tig telephone number, what was it? A modem? A • dialtonc? A very special operator? No lo all of the above- -(Ais was something truly amazing and unique. This was TRAVELNET. Of ™uTw t he didn’t know at the time what he had dialed into. But this is what he heard. Two rings,a tone that lasted For about half a Hftnnd (it hud about the same pitch of a Sprint tone), and then a voice! Noi just a recording, not just a human asking whal it was you wanted but a recording asking you what it was you wanted ! Sort of like hearing an answering machine for the first time, but this was no answering machine. "Authorization number, please,* tt sensual, husky female voice asked. And since he was a rather clever guy. be hit his t.ouch tone* keypad. Every timehe entered a tone, he heard a short “hooop," like an acknowledgement of some sort. After four of these “booops* the automated hdycame back and said "fetgJifceightsevetKero." But, alas, those were not 1 tic keys he hit. Jn semi-desperation, he hit another key. The female voice came back and said, “Please repeat, yes or no 1 ?" But whal was the question? He quickly realized that she must have lwti somehow Hying to confirm the entry of his numbers. But how do you convey the word “no” on a touch tone* keypad? He went through the whole process again and wound up getting dumped into a recording that said fin an authoritative female voice}, "The Trftvtlnei number you dialed is incorrect- please check the number and dial again." He called hack. Again he tried entering numbers and tried to figure out why they wouldn’t correspond. All of a sudden, his baby sister (who had been growing increasingly bored with a raltlc in the neKt room), decided to let out ibe son of scream ibai baby sisters arc known for. What’s important about this is that after the scream was over, our friend heard quite disci nelly over the telephone lines; "booop “Wow," he said. "Booop," it repeated. It recognized speech! He called it back and started entering numbers with his voice. It worked! . After four numbers were entered, Ll would repeat them back to him and he had the option of saying either “^es” or "no” If he said L, ycs"or remained silent, he had the opportunity to enter four more numbers. If he sjj id “no” the machine would make every effort to find out what the number was by asking him twice just what it was he meant to say. There were a few simple rules— he had to enunciate clearly and say the word “zero” instead of “oh". . But what would this lady let him do if he guessed the right eight numbers? And how could he possibly get such a long number anyway. Would he have to call up the lady and slowly and patiently pronounce Lillie words over and over? Since he knew that there were over 100,000,000 possible combinations and that no more than a thousand probably worked, fie understood that it would take some thinking to satisfy the mechanical voice. He needed lo find some good Old- fashioned human incompetence . If the machine had trouble hearing him. or if he remained silent, it would eventually say. "Sorrv, we’re having difficulties. H Then it would connect him lo a human, rie stuck on the line and when the operator answered, he asked her what number he haddialed. "This is Genera I Motors Travelnet, sir,’* she replied. **l Yn terribly sorry, ^he said. “I was trying lo gel the speaking clock. "'Thal^ okay, " the operator said. "Goodbye.” So il was General Motors f This would be easy. He waited a day and called back. He got connected to another operator, who a^ked him whal he wanted. "This i* J.C. Slcppleworth from Fort Wayne GMAC, H he snarled. "And I've been having trouble using, ibis confounded phone system, "“Well, why don't you call the instruction number, sir? She gave him the number. He called this number and heard a full demonstration on how to use the system. It was used to make phone calls, which he sort of suspected. After you enter your eight-digit code, you enter a ten-digit phone number or. if dialing internally within General Motors, a seven-digit number. The recording even spoke a demo authorization code to get the point across. After hearing this, our friend wondered if he should try l hie demo code. “No.” he deckled, “They couldn't possibly be that stupid.** He tried it anyway and! guess what? The moment he confirmed the last number, the lovely voice asked a new question! "Destination code, please?* (In other words, the phone number you're trying to call.) It was an extender — a long and short distance phone service. He proceeded to test il, out. and he found that he could call virtually anywhere in the country for free. But who carts about free calls? He wanted to explore. And explore he did. He tried many things and learned many things. He found ihathe could avoid the ItidyY voice if he keypadded in the numbers before she could speak. This way the call would go through normal Lywithoui any arguments, on pronunciation. This allowed him to test many, many codes without much hassle. He found that by mixing up his working code a little, he was able in find many new ones. The simplicity was astounding. In a short lime, he had found Literally hundreds of codes. After this, he sat down one day and stared at his list of codes. Alt of a sudden, he realized something. Each group of fouradded up toeilher?, 19. nr 39- a sort of base-nine code. He wrote a short program and printed out all possible four-digit combinations that added up to these magic numbers. He was set tV \ life. He used the system to explore internal offices. If no area code was entered , every "exchange put you in a different.ps rt of the country . One cjicfiangt.W, simply dumped him Into a feed from a Detroit radio station. One day, his Demons! ialcr, which is basically a touch tond* generator with a memory, came across a re-order fa fast busy signal) that turned into a diaitone in twenty seconds. The connection wasn^ great, but he found that he could make a direct call dfirwfaw. He could dial overseas directly. He figured that he was at the switchboard of someoffioc branch faraway from where he originally cal led- He found. : out whal the number was by calling a friend person-to-person colled, who then asked the operator for the number so that tht"perst}n**cau]d call back when he. returned. When he called up the number he was dialing from, they answered, “CM AC." So it was some distant office that be was making his calls out of. using a Travelnet code and an . ■ internal number to gel there. It was so roundabout that he knew nobody would figure it out. In fact, several people that he called received calls from that office asking if they knew anybody wbo worked there that would call them at three in the morning. .It was incredible! Even if a friend had wanted to frame him. it was doubtful that they would connect him with this distant city from which the call supposedly emanated. And the funny thing was that the company was probably placing a 24-hour armed guard on the building, thinking that someone was breaking inand making calls. Someone was, but in a way they could never figure out. There’s much more to the world of Travelnet, particularly on their internal network. And the same number works to this very day, which, by the way. is toll-free. But we Ve heard of cases where people have been trapped into paying for whal they did and it^s quite likely the system is heavily monitored. A simitar system called WIN was used by Wcstinghouse before they gave up i n d isgust after their lines were constantly tied uphy phreaktrs and hackers. Honeywell makes the actual system and there are others in use around the country one. wt hear, for the state offices of I Hi nois, a not her for ; Ralstcin-Purina . the folks who blow up sewers i ' Louisville, KV.

The first obstacle for a slug is the magnetic crap. This will slop any light-weight . magnetic slupnnd coins, If ii ptaxt this, the slug is then classified ota nickel, dime, orquarter. Each slug, is then checked far appropriate iin And weight. If these teats are passed. it wilt then travel through a nickel, dime, or quarter magnet as a ppropriate. These magnets set up an eddy current effect which causes coins of the appropriate characteristics to stow down so they will follow die correct trajectory. If all goes well, the coin will follow the correct pnth(u*ch as bouncing off of the nickel anvil) where it wilt hopefully fall into the narrow accepted coin channel. The rather elaborate teds that arc performed as the coin travel down the coin chute will scop most slug* and other undesirable coins, such ns pennies, which must then be retrieved using the coin release kver. If the slug miraculously survives the gamut, it will then strike the appropriate totalizer arm causing a rale hr I wheel In rotate mux- for every 5 cent irucftnKnl (e.g-. a quarter will cause it to rotate 3 times). The totalizer then causes the coin signal oscillator to readout a dual-frequency signal indicating the value deposited to acts (a computer) or the TSPS operator. These are the same tons? used by phreaka in the iubmout red boxes. For a quarter, 5 beep tomarc outpulscd at [2-1? pulses -per second | PPS). A dime causes 2 beep lonnat 5-H.S l*PS while a ntckd causes one beep tme at 5-8.5 PRS, A beep con si sis of 3 tones: 2300 +1700 Hz. A relay in the fortress called the "B relay 1 " ( yes, l he re is also an ‘'A relay") placet a capacitor serosa the speech circuit during totqlinr readout to prevent the “customer" from hearing the ted box tones. Ln older 3 slot, phones, one bell ( 10 KM 100 Hz.) for a nickel, two bells for a dime, and one gong (H00 Hz.) for a quarter arc used instead of ihe modem JH^jrfrequcncy tones. ' TSPSiidArre u'hile fonrCHHCS are connected to the CD of the am. all transactions are handled via the Traffic Service Position System f]"SPS). In arms that do not have AdS, all calls that require operator assistance, such as culling card and collect., are automatically routed to a TSPS operator position. In an effort to automate fortress service, a computer system known Us Automated CoinToLI Service (ACTS) has been implemented in many areas, ACTS listens to the red ho* rignari fmm Ihefoncuand lakes appropriate action. It is ACTS which say*. "Two dollars please.f pause) Please deposit two dollar* for the next len seconds... " and other variations. Also, if you la Ik for more tha n three minutes, and then hangup. ACTS will tail back and demand your money. ACTS is responsible far Automated Calling Card Service, too. In addition. ACTS provides trouble diagnosis for craftspeople (repairmen specializing in fori res ses). For example, there is a coin test which is great for tuning up red boxes. In many areas thin test can be activated by dialingQ959 1 2.10 at a fortress (thanks to Karl Marx for this information), Once activated it will request that you deposit variouscoins. It w ill (hen identify the coin and output the appropriate red box signal. The cuirts a re usually returned when you hang up in make sure that there is actually money in the Tone, the CO initiates a "ground test" at various limesfodetemnine if & coin k& actually in the font. This is why you mu*i deposit at least a. nickel in order to wv a red box! Green Boxes Faying the initial rate m older to ure a red box (on certain fortresses) left a sour taste in rrsinv ted hniter^ mouths. Thu* (he jim bo* wps invented. The green box generates useful tow such, as COIN COLLECT, COIN RETURN, and HIN(jBACK. These are the tunes that ACT'S or IhcTSPS operator would nend (a. the CO when appropriate. IJ nfortunately . the green box cannot be used at a fonrens ^talkm but it must be used by (he tulini party. Here are the lores: COIN COLLECT 7M * 1 1 » Hi, COIN R FTVW* IIWtinOHt, RINGS ACK TH«1THHe. Before the calked party sends any of (best tones, an operator released signal _>^uld he sent to alert (he MFdelCCtnrsat I he CO. This can be accomplished by IKX) H?, ora single 2M0 Hz. wink (90 ms) followed hyaWlmipap .j then the uppmpriatc signal for at least 9W ms. A Isn, do not forjiet that the iml ial rate iseolleeted shortly before I be 3 minute periraJ is up. Incidentally, once the stove MF tones for colloctingaiid rttu mingcoitlfi reach the CO. (hey are converted into an appropriate DC pu Ise { - 1 30 volts for return and *1 JO volt! for crilrri), This pulse is then sent down the tip 10 the fortress. Thix cause* the coin relay to either return or collect the Midi. The ilkpd "T-Network" take* advantage of this information- When a pulse for COIN COLLECT [+IJ0 VDC) is sen! down the line, it must be grounded somewhere. This is, usually either (he yellow or black wine. Thus, if the wire" are exposed, these wires dn be cm lo prevent the pulse from beinggrounded. When the three minute inilia.1 period hahttOsl up. make sure thti the black and yellow wires a re severed, then hangup, wail about 1 .5 seconds in case ofa second pulse, reconnect the wires, pick up Ihe tone, hang upagain, and if all goes well it should be jackpot time. Physical Attack A iy pica I fortress weighs roughly 50 pound! with an empty coin box. Most of this is accounted for in the armor plating. Why all the security? Well, Bell attributes it to the follwing: “Social changes during the lWfl^i made the multisloi coin station a prime target for vandalism, strong arm robbery, fraud, and theft of service. This brought about the introduction of Ihe more rugged single slot coin station and a new environment foF coin service . 1h [we related, story, pap: 1-63], As for picking the lock- 1 will quote Mr. Phelps: "We often fantasjje about "picking the lock’ or 'getting a master key". Well, you can forget about it. E don't like to discourage people, but it will save you from waiLing a lot or your time time which can be put to better use (heh, hrh).!’ As for physical attack, the coin plate is secured on all four sides by hardened steel bolts which passthrough two slatseach. The**- bolts a re in LU-m interlocked by the main lock. One phreak l know did manage to take one of the ’ ‘mothers'* home (it *hh attached in a piece of plywood at a consinxiioii site! otherwise. the permanent ones arc a bitch to detach from the wall!). It took him almost ten hours to open the coinbox using a power drill. Pledge hammers, and crow bars.
