It was a means of in-band signaling to simulate the action of the push-to-talk and release-to-listen (often referred to as PTT) button commonly found on two-way radio systems and walkie-talkies.

Push-to-talk Push-to-talk (PTT), also known as press-to-transmit, is a method of having conversations or talking on half-duplex communication lines, including two-way radio, using a momentary button to switch from voice reception mode to transmit mode. For example, an air traffic controller usually talks on one radio frequency to all aircraft under his/her supervision. Those under the same frequency can hear others' transmissions while using procedure words such as "break" , "break break" to separate order during the conversation (ICAO doc 9432). In doing so, they are aware of each other's

Multiple walkie-talkies use a single radio channel, and only one radio on the channel can transmit at a time, although any number can listen. The transceiver is normally in receive mode; when the user wants to talk they must press a "push-to-talk" (PTT) button that turns off the receiver and turns on the transmitter.

For example; the sequence "12334" is actually transmitted as "123E4". If a transmission would have multiple repeats, like "12333", it would be transmitted as "123E3" in order to not have the same problem again. Automatic Number Identification or ANI, is a scheme that uses selcall for identification purposes. Typically a mobile radio will be configured to transmit a preconfigured selcall sequence when the user presses the ‘push-to-talk’ (PTT) button, which will automatically identify them to other devices listening on

A significant advantage of PTT is the ability for a single person to reach an active talk group with a single button press; users need not make several telephone calls to coordinate with a group. Push-to-talk cellular calls similarly provide half-duplex communications — while one person transmits, the other(s) receive. This combines the operational advantages of PTT with the interference resistance and other virtues of mobile phones. Mobile push-to-talk services, offered by some mobile carriers directly as

Repeaters are by nature full duplex, most mobiles and almost all handhelds are half duplex. Some systems use a mix of the two where radios use duplex as a default but can communicate simplex on the base station channel if out-of-range. In the US, the capability to talk simplex on a duplex channel with a repeater is sometimes called talk-around, direct, or car-to-car. In two-way radios with headsets, a push-to-talk button may be included on a cord or wireless electronics box clipped to the user's clothing. In

The earphone reproduces the speech of the remote party as the microphone transmits the speech of the local party, because there is a two-way communication channel between them, or more strictly speaking, because there are two communication channels between them. In a half-duplex system, both parties can communicate with each other, but not simultaneously; the communication is one direction at a time. An example of a half-duplex device is a walkie-talkie two-way radio that has a "push-to-talk" button; when the local user

In a typical installation, each radio in a system is assigned a unique seven-tone code. Each time the radio's push-to-talk button is pressed, the radio transmits the seven tone sequence at the beginning of the transmission. To prevent the user from talking while the tone sequence is broadcast, the seven-tone sequence is played over the two-way radio receiver's speaker. Modat tone sequences are described as either a six-digit or seven-character string. For example, a single Modat code could be described as either 698R124

Since the new format organized radio stations via genre, listeners had very limited range in what music they hear unless they regularly switch from station to station. The change also eliminated the feature that suggested songs and artists based on the user's ratings. Listeners had the option to listen to those stations in high quality (broadband) audio as well as using the 6 skips-per-hour (not applicable on local stations). One way around the inability to skip songs was to simply hit the browser's refresh button. While it took time for the page to reload, it was faster

This could potentially lead to an elevator stopping to pick up more passengers than the elevator actually has capacity for, creating delays for other users. This situation is handled by two solutions, a load vane sensor on the elevator or a group function button on keypad. The load vane tells the elevator controller that there is a high load in car and doesn't stop at other floors until the load is low enough to pick up more passengers.

This is what gives way to the trademark overdriven tone. The shape of the compression curve changes dramatically in All-Button. Where 4:1 is a gentle slope, All-Button is more like severe plateau!

Methods for mitigating the self interference caused by simultaneous transmission and reception on different but close-spaced frequencies include using two antennas, or dynamic solid-state filters. Time-division technologies (such as TDD) are used for mitigating self interference by simultaneous transmission and reception on the same frequency. Installation of receivers and transmitters at the same fixed location allowed exchange of messages wirelessly.

The function of carrying simultaneous conversations over a single channel is called multiplexing. Instead of channels, radios are related by groups which may be
