Red Boxing With Whistles
|

This article is presented as a news item only. It is not to be taken as an
|
|
encouragement to make fraudulent telephone calls.
|
|
|
|
Red boxing consists of simulating the tones produced when coins are
|
|
deposited in a pay phone. Coin tones are beeps of 2200 Hz + 1700 Hz as
|
|
follows:
|
|
|
|
5 cents - 1 beep, 66 milliseconds duration.
|
|
|
|
10 cents - 2 beeps, each 66 milliseconds duration with 66 millisecond
|
|
pause between beeps.
|
|
|
|
25 cents - 5 beeps, each 33 milliseconds duration with a 33 millisecond
|
|
pause between beeps.
|
|
|
|
Two methods have commonly been used by phone phreaks to produce these
|
|
tones and make free calls.
|
|
|
|
1. The traditional Red Box consisting of a pair of Wien-bridge oscillators
|
|
with the timing controlled by 555 timer chips.
|
|
|
|
2. Producing the signals with a computer which are recorded and then
|
|
played back into the mouth piece of a pay phone.
|
|
|
|
A third method has recently appeared which is a real mind blower. A phreak
|
|
in the Midwest has extensively tested a method of red boxing which uses
|
|
nothing more than a pair of brass or aluminum whistles. The whistles are
|
|
1/4 inch in diameter by 4 inches long and are tuned by means of a wooden
|
|
dowel rod which fits snugly inside. The whistles can be brought precisely
|
|
on frequency by tuning them against a known signal source such as a
|
|
computer capable of producing the tones. Once tuned, the whistles are
|
|
glued or taped together so they can be blown together to produce the dual
|
|
tone used in coin signaling. It has been tested and proven that with a
|
|
little practice these whistles can be used to make free calls. Now you can
|
|
blow your money without spending a cent.
