        HOW TO BE A REAL PHREAK

IN THE PHONE PHREAK SOCIETY THERE ARE CERTAIN VALUES THAT EXIST IN ORDER TO
BE A TRUE PHREAK, THESE ARE BEST SUMMED UP BY THE MAGICIAN: "MANY PEOPLE
THINK OF PHONE PHREAKS AS SLIME, OUT TO RIP OFF BELL FOR ALL SHE IS WORTH.
NOTHING COULD BE FURTHER FROM THE TRUTH! GRANTED, THERE ARE SOME WHO GET
THEIR KICKS BY MAKING FREE CALLS; HOWEVER, THEY ARE NOT TRUE PHONE PHREAKS.
REAL PHONE PHREAKS ARE 'TELECOMMUNICATIONS HOBBYISTS' WHO  EXPERIMENT, PLAY
WITH AND LEARN FROM  THE PHONE SYSTEM. OCCASIONALY THIS EXPERIMENTING, AND A
NEED TO  COMMUNICATE WITH OTHER PHREAKS ( WITH- OUT GOING BROKE), LEADS TO
FREE CALLS.  THE FREE CALLS ARE BUT A SMALL SUBSET OF A >TRUE< PHONE PHREAKS
ACTIVITIES.

         THE TEN COMMANDMENTS

REPRINTED FROM TAP ISSUE #86.  (TAP, ROOM 603, 147 W 42 STREET, NEW YORK, NY
10036.  SEND A SASE FOR THEIR INFO SHEET "WHAT THE HELL IS TAP?" AND TELL
THEM THAT BIOC AGENT 003 TOLD YOU ABOUT IT.)

  THE PHONE PHREAK'S TEN COMMANDMENTS

   I.  BOX THOU NOT OVER THINE HOME TELEPHONE WIRES, FOR THOSE WHO DOEST MUST
SURELY BRING THE WRATH OF THE CHIEF SPECIAL AGENT DOWN UPON THY HEADS.

  II.  SPEAKEST THOU NOT OF IMPORTANT MATTERS OVER THINE HOME TELEPHONE
WIRES, FOR TO DO SO IS TO RISK THINE RIGHT OF FREEDOM.

 III.  USE NOT THINE OWN NAME WHEN SPEAKING TO OTHER PHREAKS, FOR THAT EVERY
THIRD PHREAK IS AN FBI AGENT IS WELL KNOWN.

  IV.  LET NOT OVERLY MANY PEOPLE KNOW THAT THY BE A PHREAK, AS TO DO SO IS
TO USE THINE OWN SELF AS A SACRIFICIAL LAMB.

   V.  IF THOU BE IN SCHOOL, STRIVE TO GET THIN SELF GOOD GRADES, FOR THE
AUTHORITIES WELL KNOW THAT SCHOLARS NEVER BREAK THE LAW.

  VI.  IF THOU WORKEST, TRY TO BE A EMPLOYEE, AND IMPRESSEST THINE BOSS WITH
THINE ENTHUSIASM, FOR IMPORTANT EMPLOYEES ARE OFTEN SAVED BY THEIR OWN
BOSSES.

 VII.  STOREST THOU NOT THINE STOLEN GOODES IN THINE OWN HOME, FOR THOSE WHO
DO ARE SURELY NON-BELIEVERS IN THE BELL SYSTEM SECURITY FORCES, AND ARE NOT
LONG FOR THIS WORLD.

VIII.  ATTRACTEST THOU NOT THE ATTENTION OF THE AUTHORITIES, AS THE LESS
NOTICABLE THOU ART, THE BETTER.

  IX.  MAKEST SURE THINE FRIENDS ARE INSTANT AMNESIACS AND WILL NOT REMEMBER
THAT THOU HAVE CALLED ILLEGALLY, FOR THEIR COOPERATION WITH THE AUTHORITIES
WILL SURELY LESSEN THINE TIME FOR FREEDOM ON THIS EARTH.

   X.  SUPPORTEST THOU TAP, AS IT IS THINE NEWSLETTER, AND WITHOUT IT, THY
WORK WILL BE FAR MORE LIMITED.

             CN/A NUMBERS

CUSTOMER NAME & ADDRESS BUREAUS EXIST SO THAT AUTHORIZED BELL EMPLOYEES MAY
OBTAIN THE NAME & ADDRESS OF ANY CUSTOMER IN THE BELL SYSTEM BY GIVING THE
CN/A OPERATOR THE CUSTOMER'S TEL. # ALL CUSTOMERS ARE MAINTAINED ON FILE
INCLUDING UNLISTED #'S.  THESE BUREAUS HAVE MANY USES FOR PHREAKS.

HERE IS HOW AN EMPLOYEE MIGHT GO ABOUT CALLING CN/A: "HI, THIS IS JOHN DOE
FROM THE MIAMI RESIDENTAL SERVICE CENTER, CAN I HAVE THE CUSTOMERS NAME AT
(123) 555-1212." THE EMPLOYEES USUALLY USE THESE FOR CHECKING WHO BELONGS TO
A # THAT SOMEONE CLAIMED THEY DIDN'T CALL.

IF YOU SOUND CHEERY AND NATURAL THE OPERATOR WILL NEVER ASK ANY QUESTIONS. IF
YOU DON'T SOUND LIKE A MATURE ADULT, DON'T USE IT!  ALWAYS PRACTICE FIRST &
SO YOU DON'T SCREW UP AND MAKE THE OPERATOR SUSPICIOUS.  USE NAME THAT SOUNDS 
REAL, NOT YOUR PIRATE NAME EITHER!  ALSO SAY THAT YOU ARE FROM A CITY THAT IS
FAR AWAY FROM THE ONE THAT YOU ARE CALLING.

THE CN/A NUMBER FOR THE NY AREA & VICINITY (212, 315, 516, 518, 607, 716, & 
914) IS>>>>>>>>>(518) 471-8111<<<<<< AND IS OPEN DURING BUSINESS HOURS. DON'T 
ABUSE IT! 

            AT&T NEWSLINES 

AT&T NEWSLINES ARE NUMBERS AT AREA PHONE OFFICES THAT TELCO EMPLOYEES CALL TO 
FIND OUT THE LATEST INFO ON NEW TECHNOLOGY, STOCKS, ETC.  THE RECORDED
REPORTS RANGE FROM VERY BORING TO VERY INTERESTING. 

HERE ARE A FEW OF THE NUMBERS:
 *(201) 483-3800 NJ  (518) 471-2272 NY 
  (203) 771-4920 CN  (717) 255-5555 PA 
  (212) 393-2151 NY  (717) 787-103q PA 
  (516) 234-9941 NY *(914) 948-8100 NY 

SOME OF THESE NUMBERS ARE TOLL-FREE, BUT YOU CAN'T ALWAYS COUNT ON IT. 

* THESE NUMBERS ARE NOT ALWAYS UP! 

NUMBERS FROM OTHER AREAS ARE AVAILABLE BY REQUEST FROM F)BIOC  L)AGENT 003. 
             ANI NUMBERS

ANI NUMBERS IDENTIFY THE PHONE NUMBER THAT YOU ARE CALLING FROM.  IT IS 
USEFUL WHEN PLAYING IN CANS (THOSE BIG SILVER BOXES ON TELEPHONE POLES) TO 
FIND OUT THE # OF THE LINE.  IT IS ALSO GOOD TO FIND OUT THE # OF A PHONE 
THAT DOESN'T HAVE IT PRINTED ON IT.  IN THE 914 AREA CODE THE ANI # IS 990.  
IF YOU JUST HAVE TO DIAL THE LAST 4 DIGITS FOR A LOCAL #, IE CONGERS (268), 
DIAL 1-990-1111, WHERE 1111 ARE DUMMY DIGITS THERE IS ALSO A LESS USEFUL TYPE 
ANI # WHICH WILL IDENTIFY THE AREA CODE & EXCHANGE.  IT IS NXX-9901, WHERE 
NXX IS THE EXCHANGE.  IN THE 212 & 516 AREA CODES THE ANI # IS 958. 

          PHREAK NEWSLETTER 

TAP IS THE "OFFICIAL" PHONE PHREAK NEWSLETTER, AND HAS EXISTED SINCE 1971.
EACH 4 PAGE ISSUE IS CRAMMED FULL OF INFORMATION ON PHONE PHREAKING, COMPUTER 
PHREAKING, FREE GAS, FREE ELECTRICITY, FREE POSTAGE, BREAKING & ENTERING 
INFO, ETC.  IT IS LARGELY PHONE PHREAK ORIENTED, HOWEVER. 

A 10 ISSUE SUBSCRIPTION COSTS $8.00, IF YOU GET A BULK RATE SEALED ENVELOPE 
SUBSCRIPTION.  I WOULD RECOMMEND THE FIRST CLASS SUBSCRIPTION, WHICH IS $10. 

AS OF THIS WRITING (7-16-83), THE CURRENT ISSUE IS #86, AND ISSUE #50 IS 8 
PAGES INSTEAD OF THE USUAL 4.  BACK ISSUES ARE $0.75 EACH, AND ISSUE #50 IS
$1.50.  A BRIEF INDEX TO THE FIRST 80 ISSUES IS AVAILABLE FOR A SASE, OR FREE 
WITH A SUBSCRIPTION ORDER.  TAP IS NON-PROFIT, AND IN DESPERATE NEED OF
MATERIAL (ARTICLES), MONEY, AND VOLUNTEERS.

BELIEVE ME:  IT WILL BE THE BEST $10 
             YOU WILL EVER SPEND... 

              BLACK BOX 

  THE BLACK BOX IS A DEVICE THAT ATTACHED TO A CALLED PARTIES PHONE THAT
ALLOWS HIM/HER TO RECEIVE FREE LONG DISTANCE CALLS FROM FRIENDS WHO CALL. 

YOU ONLY NEED 2 PARTS:  A SPST TOGGLE SWITCH AND A 10,000 OHM (10  K), 1/2 
WATT,  10%  RESISTOR.  ANY ELECTRONICS PLACE SHOULD HAVE THESE. 

NOW,  CUT TWO PIECES OF WIRE, ABOUT 6 INCHES, AND ATTACH THESE TO THE TWO 
SCREWS ON THE SWITCH.  TURN YOUR NORMAL DDSIDE DOWN AND UNSCREW THE 2 SCREWS. 
LOCATE THE "F" AND "RR" SCREWS ON THE NETWORK BOX.  WRAP THE RESISTOR BETWEEN 
THESE 2 SCREWS AND MAKE SURE THAT THE WIRES TOUCH ONLY THE PROPER TERMINALS!
NOW CONNECT ONE WIRE FROM THE SWITCH TO THE RR TERMINAL.  FINALLY, ATTACH THE 
REMAINING WIRE TO THE GREEN WIRE (DISCONNECT IT FROM ITS TERMINAL).  NOW
 BRING THE SWITCH OUT THE REAR OF THE PHONE AND CLOSE IT UP.  PUT THE SWITCH
IN A POSITION WHERE YOU GET A DIAL TONE, MARK THIS NORMAL.  MARK THE OTHER 
SIDE FREE. 

  WHEN YOUR FRIENDS CALL (AT A PREAR- RANGED TIME), QUICKLY LIFT & DROP THE 
RECEIVER AS FAST AS POSSIBLE.  THIS WILL STOP THE RINGING, IF NOT TRY AGAIN.  
IT IS VERY IMPORTANT THAT YOU DO IT FAST! NOW PUT THE SWITCH IN THE FREE 
POSITION AND PICK UP THE pHONE. KEEP ALL CALLS SHORT & UNDER 15 MINUTES. 

WHEN SOMEONE CALLS YOU LONG-DISTANCE, THEY ARE BILLED FROM THE MOMENT YOU
ANSWER. THE TELCO KNOWS WHEN YOU ANSWER DUE TO A CERTAIN AMOUNT OF VOLTAGE 
THAT FLOWS WHEN YOU PICK UP THE PHONE. HOWEVER, THE RESISTOR CUTS DOWN ON THE
VOLTAGE SO IT IS BELOW THE BILLING RANGE BUT SUFFICIENT ENOUGH TO OPERATE THE
MOUTHPIECE.  ANSWERING THE PHONE FOR A FRACTION OF A SECOND STOPS THE RING 
BUT IT IS NOT ENOUGH FOR BILLING TO START.  IF THE PHONE IS ANSWERED FOR EVEN 
ONE FULL SECOND, BILLING WILL START AND YOU WILL BE CUT OFF  WHEN YOU HANG UP 
AND SWITCH TO FREE. 

WARNING:  BELL CAN RANDOMLY LOOK FOR 
          BLACK BOXES SO BE CAREFUL!

              DIAL LOCKS 

HAVE YOU EVER BEEN IN AN OFFICE OR SOMEWHERE AND WANTED TO MAKE A FREE FONE 
CALL BUT SOME ASSHOLE PUT A LOCK ON THE FONE TO PREVENT OUT-GOING CALLS? 

FRET NO MORE PHELLOW PHREAKS, FOR EVERY SYRTEM CAN BE BEATEN WITH A LITTLE 
KNOWLEDGE!

THERE ARE TWO WAYS TO BEAT THIS OBSTACLE, FIRST PICK THE LOCK, I DON'T HAVE 
THE TIME TO TEACH LOCKSMITHING SO WE GO TO THE SECOND METHOD WHICH TAKES 
ADVANTAGE OF TELEPHONE ELECTRONICS. 

TO BE AS SIMPLE AS POSSIBLE, WHEN YOU PICK UP THE FONE YOU COMPLETE A CIRCUIT 
KNOW AS A LOCAL LOOP.  WHEN YOU HANG-UP YOU BREAK THE CIRCUIT.  WHEN YOU DIAL 
(PULSE) IT ALSO BREAKS THE CIRCUT BUT NOT LONG ENOUGH TO HANG UP!  SO YOU CAN 
"PUSH-DIAL."  TO DO THIS YOU >RAPIDLY< DEPRESS THE SWITCHHOOK.  FOR EXAMPLE, 
TO DIAL AN OPERATOR (AND THEN GIVE HER THE NUMBER YOU WANT CALLED) >RAPIDLY<
& >EVENLY< DEPRESS THE SWITCHHOOK 10 TIMES.  TO DIAL 634-1268, DEPRESS 6 X'S 
PAUSE, THEN 3 X'S, PAUSE, THEN 4 X'S, ETC.  IT TAKES A LITTLE PRACTICE BUT
YOU'LL GET THE HANG OF IT.  TRY PRACTICING WITH YOUR OWN # SO YOU'LL GET A
BUSY TONE WHEN RIGHT.  IT'LL ALSO WORK ON TOUCH-TONE(TM) SINCE A DTMF LINE 
WILL ALSO ACCEPT PULSE.  ALSO, NEVER DEPRESS THE SWITCHHOOK FOR MORE THAN A 
SECOND OR IT'LL HANG-UP! 

FINALLY, REMEMBER THAT YOU HAVE JUST AS MUCH RIGHT TO THAT FONE AS THE 
ASSHOLE WHO PUT THE LOCK ON IT! 

           EXCHANGE SCANNING 

ALMOST EVERY EXCHANGE IN THE BELL SYSTEM HAS TEST #'S AND OTHER "GOODIES" 
SUCH AS LOOPS WITH DIAL-UPS.

THESE "GOODIES" ARE USUALLY FOUND BETWEEN 9900 AND 9999 IN YOUR LOCAL 
EXCHANGE.  IF YOU HAVE THE TIME AND INITIATIVE, SCAN YOUR EXCHANGE AND YOU 
MAY BECOME LUCKY! 

HERE ARE MY FINDINGS IN THE 914-268 EXCHANGE: 


9900 - ANI (SEE SEPARATE BULLETIN) 9901 - ANI (SEE SEPARATE BULLETIN) 9927 - 
OSC. TONE (POSSIBLE TONE SIDE OF
       A LOOP) 9936 - VOICE #`TO THE TELCO CENTRAL 
       OFFICE 9937 - VOICE # TO THE TELCO CENTRAL
       OFFICE 9941 - COMPUTER (DIGITAL VOICE
       TRANSMISSION?) 9960 - OSC. TONE (TONE SIDE LOOP) -- 
       MAY ALSO BE A COMPUTER IN SOME 
       EXCHANGES 9961 - NO RESPONSE (OTHER END OF LOOP?) 9962 - NO RESPONSE 
(OTHER END OF LOOP?) 9963 - NO RESPONSE (OTHER END OF LOOP?) 9966 - COMPUTER 
(SEE 9941) 9968 - TONE THAT DISAPPEARS--RESPONDS 
       TO CERTAIN TOUCH-TONE KEYS 

MOST OF THE NUMBERS BETWEEN 9900 & 9999 WILL RING OR GO TO A "WHAT #, 
PLEASE?" OPERATOR.

HAVE PHUN AND REMEMBER IT'S ONLY A LOCAL CALL!

      TOUCH-TONE & FREE CALLS 

THERE ARE SEVERAL WAYS TO MAKE FREE CALLS (SPRINT, MCI, ETC.) USING A ROTARY 
PHONE.  THEY ARE: 

 1. USE A NUMBER THAT ACCEPTS VOICE AS WELL AS DTMF.  SUCH A # IS (800) 
521-8400.  AS OF WRITING THIS, A WORKING CODE WAS 00717865. 
       A) IF USING VOICE, WAIT FOR THE COMPUTER TO SAY, "AUTHORIZATION #, 
PLEASE."  THEN SAY EACH DIGIT SLOWLY, IT WILL BEEP AFTER EACH DIGIT IS SAID.
AFTER EVERY GROUP OF DIGITSl IT WILL REPEAT WHAT YOU HAVE SAID, THEN SAY YES 
IF IT IS CORRECT, OTHERWISE SAY NO.  IF THE ACCESS CODE IS CORRECT, IT WILL
THANK YOU AND ASK FOR THE DESTINATION #, THEN SAY THE AREA CODE + NUMBER AS
ABOVE.  ANOTHER SUCH # IS (800) 245- 8173, WHICH HAS A 6 DIGIT ACCESS CODE. 
(NOTE:  IF USING TOUCH-TONE ON THIS #, ENTER THE CODE IMMEDIATELY AFTER THE 
TONE STOPS.) 

 2.  HOOK UP A TOUCH-TONE FONE INTO YOUR ROTARY FONE.  ATTACH THE RED WIRE 
FROM THE TOUCH-TONE FONE TO THE "R" TERMINAL INSIDE THE FONE ON THE NETWORK 
BOX.  THEN HOOK THE GREEN WIRE TO THE "B" TERMINAL. TO USE THIS DIAL THE # 
USING ROTARY & THEN USE THE TOUCH-TONE FOR THE CODES. (DON'T HANG UP THE 
ROTARY FONE WHILE DOING THIS THOUGH!) IF THIS DOESN'T WORK THEN REVERSE THE 2
WIRES.  (NOTE:IF YOUR LINE CAN ACCEPT TOUCH-TONE BUT YOU HAVE A ROTARY FONE 
THEN YOU CAN HOOK UP A TONE FONE DIRECTLY FOR ALL CALLS BUT THIS USUALLY
ISN'T THE CASE.)SUCH AS RADIO SHACK'S 43-138.

OTHER ALTERNATIVES 

 4.  USE A CHARGE-A-CALL FONE.  (THESE ALSO MAKE GREAT EXTENTIONS IF YOU 
REMOVE IT USING A HEX WRENCH WITH A HOLE IN THE MIDDLE ON THE CENTER 
SCREW!)--(THESE FONES FOR THE BENEFIT OF THOSE WHO DON'T KNOW ARE BLUE WITH 
NO COIN SLOTS) 

 5.  USE A PAY FONE THAT WANTS YOUR MONEY BEFORE THE DIAL TONE.  PUT IN YOUR
DIME, DIAL THE #; IF IT'S AN 800 # THEN YOUR DIME WILL COME BACK IMMEDIATELY 
PUT A DIME BACK IN (IT'LL COME BACK WHEN YOU HANG UP!)  IF IT IS A TONE FIRST
FONE  AND IT DISCONNECTS THE KEYPAD (SOME DON'T) THEN FIND ANOTHER FONE.

             TELCO TRACING 

THE GOOD 'OL DAYS: ------------------ 

WAY BACK BEFORE I WAS A PHREAK, MA BELL WOULD HAVE TO MANUALLY TRACE A CALL 
IF THEY THOUGH SOMETHING WAS FUCKED UP. FIRST THEY WOULD SEND A 2000 HZ 
TRACING TONE, THE WOULD BE FOLLOWED B ALOT OF NOISE AND CLICKS.  IT TOOK 
ABOUT 2-3 MINUTES TO TRACE A CALL AND ALOT OF PEOPLE WERE INVOLVED IN THE
PROCESS. SO AT 1 IN THE MORNING THEY WOULD HAVE TO WAKE UP PEOPLE FOT THE 
TRACEES (PHREAK JARGON FOR A PAY FONE).  BUT NEVER USE THE SAME ONE MORE THAN
ONCE OR TWICE BECAUSE THE GESTAPO(ER..EXCUSE ME  MEAN BELL SECURITY) HAS BEEN
KNOW FOR STAKING OUT TROUBLED FORTRESSES. IT'S ALSO POSSIBLE FOR TRAVELNET OR 
SP TO ASK FOR A TROUBLE # BUT THE TELCO IS SLOW IN PROCESSING 
STUFF--ESPECIALLY FOR THE COMPETITION--SO DON'T FRET PHELLOW PHREAKS. 

MODERN TECHNOLOGY: ------------------ THIS CAN BE ATTRIBUTED TO ESS + CCIS 
WHICH CAN BE TRACED IN 1 SECOND. 

         MISCELLANEOUS STUFF 

HERE ARE A PHEW (PUSHING IT ON THAT WORD) BITS OF INFO ON TELEPHONE ELEC- 
TRONICS.  IF YOU DON'T APPRECIATE IT THEN I SAY PHUCK U.

VOLTAGES: 

WHEN YOUR FONE IS ON-HOOK (IE-HUNG UP) THERE IS A 4 8 VOLT DC CURRENT FLOWING 
THROUGH THE LINE ( I HAVE A GREAT IDEA ABOUT HOOKING A BATTERY CHARGER UP TO 
MY FONE ).  WHEN THE FONE IS OFF-HOOK THE VOLTAGE DROPS DOWN TO AROUND 15VDC. 
THE BLACK BOX (SEE SEPARATE ARTICLES) EXPLOITS THIS FOR FREE CALLS SINCE BELL 
USES THIS VOLTAGE DROP WHEN THE CALLED PARTY PICKS UP TO START BILLING. BELL 
MAY ALSO REVERSE THE POLARITY OF THE LINE TO START BILLING--IF YOU HAVE A 
TONE FONE THE`KEYPAD WON'T WORK IF THE POLARITY IS REVERSED.  USUALLY, THE
RED WIRE IS CALLED THE TIP SINCE IT IS THE MORE (+) OF THE 2 WIRES + THE 
GREEN WIRE IS CALLED THE RING (-).

RING TRIP: 

WHEN SOMEONE CALLS YOU BELL HAS TO SEND 90 VOLTS AC DOWN YOUR LINE AT ABOUT 
60 HZ TO ACTIVATE YOUR BELL (THIS IS WHY DEAF PEOPLE CAN HAVE LIGHT BULBS 
FANS GO OFF INSTEAD OF A BELL). THE DEVICE THAT DOES THE RINGING IS CALLED A 
RINGING GENERATOR AND THE PROCESS OF RINGING IS CALLED A RING TRIP.  THIS 
COSTS BELL MONEY AND THEY DON'T LIKE USING ALL THAT ELECTRICITY FROM THE 
LOCAL RIP-OFF POWER COMPANY- SO LET IT RING.  THIS IS ALSO, HOW BELL CAN 
CHECK FOR EXTRA FONES FROM THEIR CENTRAL OFFICE BY SEEING HOW MUCH VOLTAGE
THE LINE TAKES WHILE RINGING AND THEY CAN TELL HOW MANY FONES YOUR NOT 
SUPPOSE TO HAVE.  SOLUTION: DISCONNECT THE BELL.

MODERN TECHNOLOGY: ------------------ 

THE 2 WORST ENEMIES TO THE PHREAK BESIDES THE FBI + BELL SECURITY,ARE: ESS + 
CCIS.  ESS STANDS FOR ELECTRONIC SWITHCING SYSTEM AND IT CAN TRACE A CALL IN 
SECONDS, IT ALSO RECORDS ALL CALLS AND CAN EVEN TAP INTO LINES (ER.. I MEAN 
CHECK FOR LINE QUALITY) AND RECORD CALLS.  CCIS STANDS FOR COMMON CHANNEL 
INTER-OFFICE SIGNALING AND IT ALLOWS FOR CONTROL SIGNALS TO BE SENT VIA 
SEPARATE DATA LINKS INSTEAD OF TONES OVER THE VOICE CHANNEL--START KISSING 
YOUR BLUE BOX GOODBYE.
