Ringtone Wikipedia. A ringtone or ring tone is the sound made by a telephone to indicate an incoming call or text message. Not literally a tone nor an actual bell like ring any more, the term is most often used today to refer to customizable sounds used on mobile phones. BackgroundeditA telephone rings when the telephone network indicates an incoming call, so that the recipient is alerted of the calling attempt. For landline telephones typically receive an electrical alternating current signal, called power ringing, generated by the telephone exchange to which the telephone is connected. The ringing current originally operated an electric bell. For mobile phones, the network sends a message to the device, indicating the incoming call. The caller is informed about the progress of the call by the audible ringing signal, often called ringback tone. Power ringing and audible ringing are not synchronized. Telephones with electromagnetic ringers are still in widespread use. The ringing signal in North America is normally specified at ca. AC with a frequency of 2. In Europe it is around 6. VAC with a frequency of 2. Hz. Some non Bell Company system party lines in the US used multiple frequencies for selective ringing. Echolink 7100 Hd Software. While the sound produced is still called a ring,1 more recently manufactured telephones electronically produce a warbling, chirping, or other sound. Variation of the ring signal can be used to indicate characteristics of incoming calls. For example, rings with a shorter interval between them might be used to signal a call from a given number. A ringing signal is an electric telephony signal that causes a telephone to alert the user to an incoming call. On a POTS interface, this signal is created by superimposing ringing voltage 9. AC at 2. 0 Hz in the USA atop the 4. VDC already on the line. This is done at the Central Office, or a neighborhood multiplexer called a SLC for Subscriber Line Carrier. Tabla Software with programmable taals, tempo and beats and real Tabla sounds, TaalMala software can be used to play any Tabla Tal as your Tabla accompanyist Lehra. SLC is a trademark of Alcatel Lucent, but is often used generically. This ring voltage came from various sources. Large central offices used motor driven generator sets for both ringing other signals such as dial tone and busy signals. In smaller offices, special sub cycle2 magnetic oscillators were used.

Originally this voltage was used to trigger an electromagnet to ring a bell installed inside the telephone, or in a near by mounted ringer box. Ps Vita Emulator Pc on this page. Fixed phones of the late 2. Mobile phones have been fully digital since the early 1. G devices, hence are signaled to ring as part of the protocol they use to communicate with the cell base stations. In POTS switching systems, ringing is said to be tripped when the impedance of the line reduces to about 6. This signals that the telephone call has been answered, and the telephone exchange immediately removes the ringing signal from the line and connects the call. This is the source of the name of the problem called ring trip or pre trip, which occurs when the ringing signal on the line encounters excessively low resistance between the conductors, which trips the ring before the subscribers actual telephone has a chance to ring for more than a very short time this is common with wet connections and improperly installed lines. The ringing pattern is known as ring cadence. This only applies to POTS fixed phones, where the high voltage ring signal is switched on and off to create the ringing pattern. In North America, the standard ring cadence is 2 4, or two seconds of ringing followed by four seconds of silence. In Australia and the UK, the standard ring cadence is 4. These patterns may vary from region to region, and other patterns are used in different countries around the world. Some central offices offer distinctive ring to identify which of multiple numbers on the same line is being called, a pattern once widely used on party line telephony. In many systems, including North America Bellcore standards, Caller ID signals are sent during the silent interval between the first and second bursts of the ringing signals. HistoryeditAT T offered seven different gong combinations for the C type ringer found in the model 5. These gongs provided distinctive tones for hearing impaired customers and to make it possible to tell which phone was ringing when several phones were placed closely together. A Bell Chime was also offered, which could be set to chime like a doorbell or to ring like an ordinary phone. While rings, ringers or ring signals or what might be viewed as the call signals which are the predecessors of ringtones date back to the beginnings of telephony, modern ringtones began to appear in the 1. Arguably the first ringtone in the modern sense appeared in the movie Our Man Flint in 1. President and rang with a distinctive musical ringtone probably made by the sound effects crew using an early analog synthesizer. Following a 1. FCCruling which permitted third party devices to be connected to phone lines, manufacturers began to produce accessory telephone ringers which rang with electronic tones or melodies rather than mechanically. People also made their own ringers which used the chip from a musical greeting card to play a melody on the arrival of a call. One such ringer, described in a 1.

Damit ausgerstet, langweilt Ihr Desktop Sie garantiert nie wiederEventually, electronic telephone ringers became the norm. Some of these ringers produced a single tone, but others produced a sequence of two or three tones or a musical melody. Some novelty phones have a ringer to match, such as a duck that quacks or a car that honks its horn. The first commercial mobile phone with customizable ring tones was the Japanese. NTT Do. Co. Mo Digital Mova N1. Hyper by NEC, released in May 1. It had a few preset songs in MIDI format. In September 1. 99. IDO, the current au, sold Digital Minimo D3. Denso. It was the first mobile phone where a user could input an original melody, rather than the preset songs. These phones proved to be popular in Japan a book1. The first downloadable mobile ring tone service was created and delivered in Finland in 1. Radiolinja a Finnish mobile operator now known as Elisa started their service called Harmonium, invented by Vesa Matti Pananen. Harmonium contained both tools for individuals to create monophonic ring tones and a mechanism to deliver them over the air OTA via SMS to a mobile handset. On November 1. 99. Digitalphone Groupe Soft. Bank Mobile started a similar service in Japan. Generation softwareeditA ring tone maker is an application that converts a user chosen song or other audio file for use as a ringtone of a mobile phone. The ringtone file is installed in the mobile phone either by direct cable connection, Bluetooth, text messaging, or e mail. Many websites also let users create ring tones from digital music or audio. The earliest ringtone maker was Harmonium, developed by Vesa Matti Paananen, a Finnish computer programmer, and released in 1. Nokia smart messaging. Andy Clarke, while working for UK Phone Provider Orange, helped created the B5 Ringtone License with the UKs Mechanical Copyright Protection Society in 1. In 1. 99. 9, Clarke registered ringtone. Scott Memphis, leader singer of Sunday Morning Sanctuary, wrote a 2. Ringtones Lullabies inspired by with the B5 Ringtone Licensing of 1. Some providers have features for users to create music tones, either with a melody composer or a sampleloop arranger, such as the Music. DJ in many Sony Ericsson phones.
