Phreaking Box
A phreaking box is a device used by phone phreaks to perform various functions normally reserved for operators and other telephone company employees. Most phreaking boxes are named after colors, due to folklore surrounding the earliest boxes which suggested that the first ones of each kind were housed in a box or casing of that color. However, very few physical specimens of phreaking boxes are actually the color for which they are named. Most phreaking boxes are electronic devices which interface directly with a telephone line and manipulate the line or the greater system in some way through either by generating audible tones that invoke switching functions (for example, a blue box), or by manipulating the electrical characteristics of the line to disrupt normal line function (for example, a black box). However a few boxes can use mechanical or acoustic methods - for example, it is possible to use a pair of properly tuned whistles as a red box. List of phreaking box types Thi ...

Phreaking
Phreaking is a slang term coined to describe the activity of a culture of people who study, experiment with, or explore telecommunication systems, such as equipment and systems connected to public telephone networks. The term ''phreak'' is a sensational spelling of the word ''freak'' with the ''ph-'' from '' phone'', and may also refer to the use of various audio frequencies to manipulate a phone system. ''Phreak'', ''phreaker'', or ''phone phreak'' are names used for and by individuals who participate in phreaking. The term first referred to groups who had reverse engineered the system of tones used to route long-distance calls. By re-creating these tones, phreaks could switch calls from the phone handset, allowing free calls to be made around the world. To ease the creation of these tones, electronic tone generators known as blue boxes became a staple of the phreaker community. This community included future Apple Inc. cofounders Steve Jobs and Steve Wozniak. The blue box ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amiga 500
The Amiga 500, also known as the A500, is the first low-end version of the Amiga home computer. It contains the same Motorola 68000 as the Amiga 1000, as well as the same graphics and sound coprocessors, but is in a smaller case similar to that of the Commodore 128. Commodore announced the Amiga 500 at the January 1987 winter Consumer Electronics Showat the same time as the high-end Amiga 2000. It was initially available in the Netherlands in April 1987, then the rest of Europe in May. In North America and the UK it was released in October 1987 with a list price. It competed directly against models in the Atari ST line. The Amiga 500 was sold in the same retail outlets as the Commodore 64, as opposed to the computer store-only Amiga 1000. It proved to be Commodore's best-selling model, particularly in Europe. Although popular with hobbyists, arguably its most widespread use was as a gaming machine, where its graphics and sound were of significant benefit. It was followed by a ...

Beige Box
In consumer computer products, a beige box is a standard personal computer (PC). It has come to be used as a term of derision implying conservative or dated aesthetics and unremarkable specifications. The term is ultimately derived from the style of many early personal computers and dedicated word processors, which were usually beige or similar colors like off white or ecru. These colors were presumably chosen to allow the machines to blend inconspicuously into a variety of settings, especially among similarly colored cubicles and office equipment. IBM's early desktop computers (e.g. IBM Personal Computer, IBM PC/AT) were not only beige, but were distinctly box-shaped, and most manufacturers of clones followed suit. As IBM and its imitators came to dominate the industry, these features became unquestioned standards of desktop computer design. Some industrial design critics derided them as indistinguishable “beige boxes.” The Commodore 64 ( RAL 1019) or early Macintosh mode ...

Magenta Box
Ringing is a telecommunication signal that causes a bell or other device to alert a telephone subscriber to an incoming telephone call. Historically, this entailed sending a high-voltage alternating current over the telephone line to a customer station which contained an electromagnetic bell. It is therefore also commonly referred to as ''power ringing'', to distinguish it from another signal, audible ringing, or ringing tone, which is sent to the originating caller to indicate that the destination telephone is in fact ringing. Specifications In landline telephones, bells or ringtones are rung by impressing a 60 to 105-volt RMS 20-Hertz sine wave across the tip and ring conductors of the subscriber line, in series with the (typically) −48 VDC loop supply. This signal is produced by a ringing generator at the central office. When the switching system directs a call to a particular subscriber line, a relay on the line card connects the ringing generator to the subscriber lin ...

Vermilion Box
The vermilion box is a hypothetical portable improvised line emulator. Its function is to spoof not only caller ID but every other aspect of an incoming telephone call, including ringing and DC line voltage. Typically, the user physically disconnects the target line from the telephone network, connects the vermilion box, and then proceeds to create a completely bogus telephone call. The vermilion box incorporates three more basic phreaking boxes: the magenta box, which generates the AC ringing signal required to make the target telephone ring; the orange box, which generates caller ID (although it is not a proper call-waiting caller ID orange box that is used but a modified orange box that generates on-hook (idle state) caller ID); and the beige box that is used to conduct the actual conversation. In addition, a DC power source is required to power the telephones on the target's line. This is a very risky and stealth-intensive technique that requires the user to physically conn ...

Frequency-shift Keying
Frequency-shift keying (FSK) is a frequency modulation scheme in which digital information is transmitted through discrete frequency changes of a carrier signal. The technology is used for communication systems such as telemetry, weather balloon radiosondes, caller ID, garage door openers, and low frequency radio transmission in the VLF and ELF bands. The simplest FSK is binary FSK (BFSK). BFSK uses a pair of discrete frequencies to transmit binary (0s and 1s) information. With this scheme, the 1 is called the mark frequency and the 0 is called the space frequency. Modulating and demodulating Reference implementations of FSK modems exist and are documented in detail. The demodulation of a binary FSK signal can be done using the Goertzel algorithm very efficiently, even on low-power microcontrollers. Variations Multiple frequency-shift keying Continuous-phase frequency-shift keying In principle FSK can be implemented by using completely independent free-running oscillat ...

Caller ID
Caller identification (Caller ID) is a telephone service, available in analog and digital telephone systems, including voice over IP (VoIP), that transmits a caller's telephone number to the called party's telephone equipment when the call is being set up. The caller ID service may include the transmission of a name associated with the calling telephone number, in a service called Calling Name Presentation (CNAM). The service was first defined in 1993 in International Telecommunication Union—Telecommunication Standardization Sector (ITU-T) Recommendation Q.731.3. The information received from the service is displayed on a telephone display screen, on a separately attached device, or on other displays, such as cable television sets when telephone and television service is provided by the same vendor. Value to society includes use by suicide-prevention hot lines and enabling businesses "like pizza restaurants and florists" to quickly have confidence in telephoned orders. The ...

Silver Box
''Silver Box'' is a 5-CD box set by Scottish rock band Simple Minds, released in October 2004. It includes ''Our Secrets Are the Same'' (as disc 5), the band's long-delayed (1999/2000) twelfth studio album of original material. Overview ''Silver Box'' is mostly made up of previously unreleased demos, BBC sessions and various live recordings from 1979 to 1995. It also includes, as a final bonus disc, their genuine twelfth studio album (of original material), ''Our Secrets Are the Same''. Originally recorded between April and June 1999 and originally planned to be released on its own in early 2000, ''Our Secrets Are the Same'' was delayed many times and even cancelled until its final inclusion in the box set. Critical reception The few professional reviews the compilation received commented on the previously elusive album ''Our Secrets Are The Same'' positively. Adam Sweeting, writing for ''The Guardian'' newspaper, opined, "The album, dating from 1999, was scuppered by le ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
