A called subscriber identification (abbreviated CSID) is a string that identifies a specific fax machine as the recipient of a fax. [1]
This string (typically less than 40 characters) is usually a combination of the fax machine's telephone number and identification of the fax machine's user.
The CSID (and related TSID) are part of the modern landline fax specification. The CSID is often the same as the same machine's transmitting subscriber identification (TSID). A CSID and TSID are usually programmed into a fax machine when the machine is set up.
When a fax machine receives a fax, it sends its CSID to the transmitting machine. The CSID is displayed on the sending fax machine and is usually recorded in the transmitting machine's log of sent faxes and printed on a report or confirmation of the fax transmission. This helps to confirm that the fax is being sent to the correct recipient.
Computer software sometimes emulates the functions of a fax machine.
A CSID and TSID are programmed into the software when it is configured. The software uses them when it sends or receives faxes.
Fax, sometimes called telecopying or telefax, is the telephonic transmission of scanned printed material, normally to a telephone number connected to a printer or other output device. The original document is scanned with a fax machine, which processes the contents as a single fixed graphic image, converting it into a bitmap, and then transmitting it through the telephone system in the form of audio-frequency tones. The receiving fax machine interprets the tones and reconstructs the image, printing a paper copy. Early systems used direct conversions of image darkness to audio tone in a continuous or analog manner. Since the 1980s, most machines transmit an audio-encoded digital representation of the page, using data compression to more quickly transmit areas that are all-white or all-black.
Short Message/Messaging Service, commonly abbreviated as SMS, is a text messaging service component of most telephone, Internet and mobile device systems. It uses standardized communication protocols that let mobile devices exchange short text messages. An intermediary service can facilitate a text-to-voice conversion to be sent to landlines.
Junk faxes are a form of telemarketing where unsolicited advertisements are sent via fax transmission. Junk faxes are the faxed equivalent of spam or junk mail. Proponents of this advertising medium often use the terms broadcast fax or fax advertising to avoid the negative connotation of the term junk fax. Junk faxes are generally considered to be a nuisance since they waste toner, ink and paper in fax machines.
Traitor tracing schemes help trace the source of leaks when secret or proprietary data is sold to many customers. In a traitor tracing scheme, each customer is given a different personal decryption key. (Traitor tracing schemes are often combined with conditional access systems so that, once the traitor tracing algorithm identifies a personal decryption key associated with the leak, the content distributor can revoke that personal decryption key, allowing honest customers to continue to watch pay television while the traitor and all the unauthorized users using the traitor's personal decryption key are cut off.)
Whitemail, coined as an opposite to blackmail, has several meanings.
Direct inward dialing (DID), also called direct dial-in (DDI) in Europe and Oceania, is a telecommunication service offered by telephone companies to subscribers who operate a private branch exchange (PBX) system. The feature provides service for multiple telephone numbers over one or more analog or digital physical circuits to the PBX, and transmits the dialed telephone number to the PBX so that a PBX extension is directly accessible for an outside caller, possibly by-passing an auto-attendant.
The Junk Fax Prevention Act (JFPA) of 2005, Pub. L.Tooltip Public Law (United States) 109–21 (text)(PDF), 119 Stat. 359 (2005), was passed by the United States Congress and signed into law by President George W. Bush on July 9, 2005. The law amends the Communications Act of 1934, significantly altering some aspects of prior amendments made by the Telephone Consumer Protection Act of 1991 and the CAN-SPAM Act of 2003 as they relate to the issue of junk fax.
A fax server is a system installed in a local area network (LAN) server that allows computer users whose computers are attached to the LAN to send and receive fax messages.
J2 Global, Inc. was an American technology holding company based in Los Angeles, California. The company provided Internet services through two divisions: Business Cloud Services and Digital Media.
Internet fax, e-fax, or online fax is the use of the internet and internet protocols to send a fax (facsimile), rather than using a standard telephone connection and a fax machine. A distinguishing feature of Internet fax, compared to other Internet communications such as email, is the ability to exchange fax messages with traditional telephone-based fax machines.
3D Fax is a computer program, developed for Microsoft Windows by InfoImaging Technologies in the mid-1990s, for file transfer via fax. The program encodes a file into an image, which the user would then print and send via a fax machine or transmit directly from the computer using a fax modem. The recipient would then scan the transmitted image or receive it via a fax modem, and use 3D Fax to decode it back to its original binary form.
Windows Messaging, initially called Microsoft Exchange Client, is an email client that was included with Windows 95, Windows 98, and Windows NT 4.0.
T.38 is an ITU recommendation for allowing transmission of fax over IP networks (FoIP) in real time.
A fax demodulator is a device used to intercept fax messages by listening in on a telephone line or radio signal.
A transmitting subscriber identification is a string that identifies a specific fax machine as the sender of a fax transmission. The transmitting machine sends its TSID to the receiving machine. The receiving machine typically prints the TSID at the top or bottom of the received fax to help the recipient determine the fax's origin. See Called subscriber identification for further information.
TSID may mean:
A fax modem enables a computer to transmit and receive documents as faxes on a telephone line. A fax modem is like a data modem but is designed to transmit and receive documents to and from a fax machine or another fax modem. Some, but not all, fax modems do double duty as data modems. As with other modems, fax modems can be internal or external. Internal fax modems are often called fax boards.
A modulator-demodulator or modem is a computer hardware device that converts data from a digital format into a format suitable for an analog transmission medium such as telephone or radio. A modem transmits data by modulating one or more carrier wave signals to encode digital information, while the receiver demodulates the signal to recreate the original digital information. The goal is to produce a signal that can be transmitted easily and decoded reliably. Modems can be used with almost any means of transmitting analog signals, from light-emitting diodes to radio.
Telex is a telecommunication service that provides text-based message exchange over the circuits of the public switched telephone network or by private lines. The technology operates on switched station-to-station basis with teleprinter devices at the receiving and sending locations. Telex was a major method of sending written messages electronically between businesses in the post–World War II period. Its usage went into decline as the fax machine grew in popularity in the 1980s.
FAX.PLUS is a cloud-based online fax service based in Geneva, Switzerland that offers individuals and corporates a solution to send and receive fax online. FAX.PLUS is a sub-organization of Alohi which is founded in 2016 and supported by the state of Geneva through FONGIT.
