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.
|
|||

|

|
|||
|
