- Red Boxing With Whistles
- by THE RESEARCHER
-
- 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.

- Please note these whistles are
- available (for test purposes only) from
