THIS PHILE IS DESIGNED TO IDENTIFY
VARIOUS KINDS OF ETF (ELECTRONIC TOLL
FRAUD) DEVICES AND TO DESCRIBE THIER
OPERATION, ACCORDING TO A BOOKLET PUT
OUT BY BELL ENTITLED: THE INVESTIGATION
AND PROSECUTION OF ELECTRONIC TOLL
FRAUD DEVICES. (FOR OFFICIAL USE ONLY).
THERE ARE SEVERAL DIFFERENT TYPES OF
ELECTRONIC EQUIPMENT WHICH MAY BE
GENERALLY CLASSIFIED AS ETF DEVICES.
THE MOST SIGNIFICANT IS THE "BLUE BOX".
THE CHARACTERISTICS OF EACH TYPE OF
DEVICE ARE DISCUSSED BELOW.
-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
*BLUE BOX*
----- ----
THE "BLUE BOX" WAS SO NAMED BECAUSE
OF THE COLOR OF THE FIRST ONE FOUND.
THE DESIGN AND HARDWARE USED IN THE
BLUE BOX IS FAIRLY SOPHISTICATED, AND
ITS SIZE VARIES FROM A LARGE PIECE OF
APPARATUS TO A MINIATURIZED UNIT THAT
IS APPROXIMATELY THE SIZE OF A "KING
SIZE" PACKAGE OF CIGARETTES.
THE BLUE BOX CONTAINS 12 OR 13
BUTTONS OR SWITCHES THAT EMIT MULTI-
FREQUENCY TONES CHARACTERISTIC OF THE
TONES USED IN THE NORMAL OPERATION OF
THE TELEPHONE TOLL (LONG DISTANCE)
SWITCHING NETWORK. THE BLUE BOX ENABLES
ITS USER TO ORIGINATE FRAUDULENT
("FREE") TOLL CALLS BY CIRCUMVENTING
TOLL BILLING EQUIPMENT. THE BLUE BOX
MAY BE DIRECTLY CONNECTED TO A PHONE
LINE, OR IT MAY BE ACOUSTICALLY COUPLED
TO A TELEPHONE HANDSET BY PLACING THE
BLUE BOX'S SPEAKER NEXT TO THE TRANS
MITTER OR THE TELEPHONE HANDSET. THE
OPERATION OF A BLUE BOX WILL BE DIS-
CUSSED IN MORE DETAIL BELOW.
TO UNDERSTAND THE NATURE OF A
FRAUDULENT BLUE BOX CALL, IT IS
NECESSARY TO UNDERSTAND THE BASIC
OPERATION OF THE DIRECT DISTANCE
DIALING (DDD) TELEPHONE NETWORK. WHEN
A DDD CALL IS PROPERLY ORIGINATED, THE
CALLING NUMBER IS IDENTIFIED AS AN
INTEGRAL PART OF ESTABLISHING THE
CONNECTION. THIS MAY BE DONE EITHER
AUTOMATICALLY OR, IN SOME CASES, BY AN
OPERATOR ASKING THE CALLING PARTY FOR
HIS TELEPHONE NUMBER. THIS INFORMATION
IS ENTERED ON A TAPE IN THE AUTOMATIC
MESSAGE ACCOUNTING (AMA) OFFICE. THIS
TAPE ALSO CONTAINS THE NUMBER ASSIGNED
TO THE TRUNK LINE OVER WHICH THE CALL
IS TO BE SENT. THE INFORMATION RELATING
TO THE CALL CONTAINED ON THE TAPE
INCLUDES: CALLED NUMBER INDENTIFICATION
, TIME OF ORIGINATION OF CALL, AND INFO
THAT THE CALLED NUMBER ANSWERED THE
CALL. THE TIME OF DISCONNECT AT THE END
OF THE CALL IS ALSO REFORDED.
ALTHOUGH THE TAPE CONTAINS INFO WITH
RESPECT TO MANY DIFFERENT CALLS, THE
VARIOUS DATA ENTRIES WITH RESPECT TO A
SINGLE CALL ARE EVENTUALLY CORRELATED
TO PROVIDE BILLING INFO FOR USE BY YOUR
BELL'S ACCOUNTING DEPARTMENT.
THE TYPICAL BLUE BOX USER USUALLY
DIALS A NUMBER THAT WILL ROUTE THE CALL
INTO THE TELEPHONE NETWORK WITHOUT
CHARGE. FOR EXAMPLE, THE USER WILL VERY
OFTEN CALL A WELL-KNOWN INWATS (TOLL-
FREE) CUSTOMER'S NUMBER. THE BLUE BOX
USER, AFTER GAINING THIS ACCESS TO THE
NETWORK AND, IN EFFECT, "SEIZING"
CONTROL AND COMPLETE DOMINION OVER THE
LINE, OPERATES A KEY ON THE BLUE BOX
WHICH EMITS A 2600 HERTZ (CYCLES PER
SECOND) TONE. THIS TONE CAUSES THE
SWITCHING EQUIPMENT TO RELEASE THE CONN
ECTION TO THE INWATS CUSTOMER'S LINE.
THE 2600HZ TONE IS A SIGNAL THAT THE
CALLING PARTY HAS HUNG UP. THE BLUE BOX
SIMULATES THIS CONDITION. HOWEVER, IN
FACT THE LOCAL TRUNK ON THE CALLING
PARTY'S END IS STILL CONNECTED TO THE
TOLL NETWORK. THE BLUE BOX USER NOW
OPERATES THE "KP" (KEY PULSE) KEY ON
THE BLUE BOX TO NOTIFY THE TOLL SWITCH-
ING EQUIPMENT THAT SWITCHING SIGNALS
ARE ABOUT TO BE EMITTED. THE USER THEN
PUSHES THE "NUMBER" BUTTONS ON THE BLUE
BOX CORRESPONDING TO THE TELEPHONE #
BEING CALLED. AFTER DOING SO HE/SHE
OPERATES THE "ST" (START) KEY TO
INDICATE TO THE SWITCHING EQUIPMENT
THAT SIGNALLING IS COMPLETE. IF THE
CALL IS COMPLETED, ONLY THE PORTION OF
THE ORIGINAL CALL PRIOR TO THE EMISSION
OF 2600HZ TONE IS RECORDED ON THE AMA
TAPE. THE TONES EMITTED BY THE BLUE BOX
ARE NOT RECORDED ON THE AMA TAPE. THERE
FOREF, BECAUSE THE ORIGINAL CALL TO THE
INWATS # IS TOLL-FREE, NO BILLING IS
RENDERED IN CONNECTION WITH THE CALL.
ALTHOUGH THE ABOVE IS A DESCRIPTION
OF A TYPICAL BLUE BOX OPERATION USING
A COMMON METHOD OF ENTRY INTO THE
NETWORK, THE OPERATION OF A BLUE BOX
MAY VARY IN ANY ONE OR ALL OF THE
FOLLOWING RESPECTS:
(A) THE BLUE BOX MAY INCLUDE A
ROTARY DIAL TO APPLY THE 2600HZ TONE
AND THE SWITCHING SIGNALS. THIS TYPE OF
BLUE BOX IS CALLED A "DIAL PULSER" OR
"ROTARY SF" BLUE BOX.
(B) ENTRANCE INTO THE DDD TOLL
NETWORK MAY BE EFFECTED BY A PRETEXT
CALL TO ANY OTHER TOLL-FREE # SUCH AS
UNIVERSAL DIRECTORY ASSISTANCE
(555-1212) OR ANY # IN THE INWATS
NETWORK, EITHER INTER-STATE OR INTRA-
STATE, WORKING OR NON-WORKING.
(C) ENTRANCE INTO THE DDD TOLL
NETWORK MAY ALSO BE IN THE FORM OF
"SHORT HAUL" CALLING. A "SHORT HAUL"
CALL IS A CALL TO ANY # WHICH WILL
RESULT IN A LESSER AMOUNT OF TOLL
CHARGES THAN THE CHARGES FOR THE CALL
TO BE COMPLETED BY THE BLUE BOX. FOR
EXAMPLE, A CALL TO BIRMINGHAM FROM
ATLANTA MAY COST $.80 FOR THE FIRST 3
MINUTES WHILE A CALL FROM ATLANTA TO
LOS ANGELES IS $1.85 FOR 3 MINUTES.
THUS, A SHORT HAUL, 3-MINUTE CALL TO
BIRMINGHAM FROM ATLANTA, SWITCHED BY
USE OF A BLUE BOX TO LOS ANGELES, WOULD
RESULT IN A NET FRAUD OF $1.05 FOR A
3 MINUTE CALL.
(D) A BLUE BOX MAY BE WIRED INTO
THE TELEPHONE LINE OR ACOUSTICALLY
COUPLED BY PLACING THE SPEAKER OF THE
BLUE BOX NEAR THE TRANSMITTER OF THE
PHONE HANDSET. THE BLUE BOX MAY EVEN
BE BUILT INSIDE A REGULAR TOUCH-TONE
PHONE, USING THE PHONE'S PUSHBUTTONS
FOR THE BLUE BOX'S SIGNALLING TONES.
(E) A MAGNETIC TAPE RECORDING
MAY BE USED TO RECORD THE BLUE BOX
TONES REPRESENTATIVE OF SPECIFIC PHONE
#'S. SUCH A TAPE RECORDING COULD BE
USED IN LIEU OF A BLUE BOX TO FRAUD-
ULENTLY PLACE CALLS TO THE PHONE #'S
RECORDED ON THE MAGNETIC TAPE.
ALL BLUE BOXES, EXCEPT "DIAL PULSE"
OR "ROTARY SF" BLUE BOXES, MUST HAVE
THE FOLLOWING 4 COMMON OPERATING
CAPABILITIES:
(A) IT MUST HAVE SIGNALLING
CAPABILITY IN THE FORM OF A 2600HZ
TONE. THIS TONE IS USED BY THE TOLL
NETWORK TO INDICATE, EITHER BY ITS
PRESENCE OR ITS ABSENCE, AN "ON HOOK"
(IDLE) OR "OFF HOOK" (BUSY) CONDITION
OF THE TRUNK.
(B) THE BLUE BOX MUST HAVE A
"KP" TONES THAT UNLOCKS OR READIES THE
MULTI-FREQUENCY RECIEVER AT THE CALLED
END TO RECEIVE THE TONES CORRESPONDING
TO THE CALLED PHONE #.
(C) THE TYPICAL BLUE BOX MUST BE
ABLE TO EMIT MF TONES WHICH ARE USED TO
TRANSMIT PHONE #'S OVER THE TOLL
NETWORK. EACH DIGIT OF A PHONE # IS
REPRESENTED BY A COMBINATION OF 2 TONES
. FOR EXAMPLE, THE DIGIT 2 IS X-MITTED
BY A COMBINATION OF 700HZ AND 1100HZ.
(D) THE BLUE BOX MUST HAVE AN
"ST" KEY WHICH CONSISTS OF A COMBINA-
TION OF 2 TONES THAT TELL THE EQUIPMENT
AT THE CALLED END THAT ALL DIGITS HAVE
BEEN SENT AND THAT THE EQUIPMENT SHOULD
START SWITCHING THE CALL TO THE CALLED
NUMBER.
THE "DIAL PULSER" OR "ROTARY SF"
BLUE BOX REQUIRES ONLY A DIAL WITH A
SIGNALLING CAPABILITY TO PRODUCE A
2600HZ TONE.

*BLACK BOX*
------ ----
THIS ETF DEVICE IS SO-NAMED BECAUSE
OF THE COLOR OF THE FIRST ONE FOUND. IT
VARIES IN SIZE AND USUALLY HAS ONE OR
TWO SWITCHES OR BUTTONS.
ATTACHED TO THE TELEPHONE LINE OF A
CALLED PARTY, THE BLACK BOX PROVIDES
TOLL-FREE CALLING *TO* THAT PARTY'S
LINE. A BLACK BOX USER INFORMS OTHER
PERSONS BEFOREHAND THAT THEY WILL NOT
BE CHARGED FOR ANY CALL PLACED TO HIM.
THE USER THEN OPERATES THE DEVICE
CAUSING A "NON-CHARGE" CONDITION ("NO
ANSWER" OR "DISCONNECT") TO BE RECORDED
ON THE TELPHONE COMPANY'S BILLING EQUIP
MENT. A BLACK BOX IS RELATIVELY SIMPLE
TO CONSTRUCT AND IS MUCH LESS SOPHISTI-
CATED THAN A BLUE BOX.
-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
*CHEESE BOX*
------- ----
THIS DEVICE IS SO-NAMED FOR THE
CONTAINER IN WHICH THE FIRST ONE WAS
FOUND. ITS DESIGN MAY BE CRUDE OR VERY
SOPHISTICATED. ITS SIZE VARIES; ONE WAS
FOUND THE SIZE OF A HALF-DOLLAR.
A CHEESE BOX IS USED MOST OFTEN BY
BOOKMAKERS OR BETTERS TO PLACE WAGERS
WITHOUT DETECTION FROM A REMOTE
LOCATION. THE DEVICE INTER-CONNECTS 2
PHONE LINES, EACH HAVING DIFFERENT #'S
BUT EACH TERMINATING AT THE SAME
LOCATION. IN EFFECT, THERE ARE 2 PHONES
AT THE SAME LOCATION WHICH ARE LINKED
TOGETHER THROUGH A CHEESE BOX. IT IS
USUALLY FOUNDN IN AN UNOCCUPIED
APARTMENT CONNECTED TO A PHONE JACK OR
CONNECTING BLOCK. THE BOOKMAKER, AT
SOME REMOTE LOCATION, DIALS ONE OF THE
NUMBERS AND STAYS ON THE LINE. VARIOUS
BETTORS DIAL THE OTHER NUMBER BUT ARE
AUTOMATICALLY CONNECTED WITH THE BOOK
MAKER BY MEANS OF THE CHEESE BOX INTER
CONNECTION. IF, IN ADDITION TO A CHEESE
BOX, A BLACK BOX IS INCLUDED IN THE
ARRANGEMENT, THE COMBINED EQUIPMENT
WOULD PERMIT TOLL-FREE CALLING ON
EITHER LINE TO THE OTHER LINE. IF A
POLICE RAID WERE CONDUCTED AT THE
TERMINATING POINT OF THE CONVERSATIONS
-THE LOCATION OF THE CHEESE BOX- THERE
WOULD BE NO EVIDENCE OF GAMBLING
ACTIVITY. THIS DEVICE IS SOMETIMES
DIFFICULT TO IDENTIFY. LAW ENFORCEMENT
OFFICIALS HAVE BEEN ADVISED THAT WHEN
UNUSUAL DEVICES ARE FOUND ASSOCIATED
WITH TELEPHONE CONNECTIONS THE PHONE
COMPANY SECURITY REPRESENTITIVES SHOULD
BE CONTACTED TO ASSIST IN
INDENTIFICATION.
(THIS PROBABLY WOULD BE GOOD FOR A BBS,
ESPECIALLY WITH THE BLACK BOX SET UP.
AND IF YOU EVER DECIDED TO TAKE THE
BOARD DOWN, YOU WOULDN'T HAVE TO CHANGE
YOUR PHONE #. IT ALSO MAKES IT SO YOU
YOURSELF CANNOT BE TRACED. I AM NOT
SURE ABOUT CALLING OUT FROM ONE THOUGH)
-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
*RED BOX*
---- ----
THIS DEVICE IT COUPLED ACOUSTICALLY
TO THE HANDSET TRANSMITTER OF A SINGLE-
SLOT COIN TELEPHONE. THE DEVICE EMITS
SIGNALS IDENTICAL TO THOSE TONES
EMITTED WHEN COINS ARE DEPOSITED. THUS,
LOCAL OR TOLL CALLS MAY BE PLACED
WITHOUT THE ACTUAL DEPOSIT OF COINS.
