ATIS is the leading technical planning and standards development organization committed to the rapid development of global, market-driven standards for the information, entertainment and communications industry.
The time over which cryptographically protected data or other security processes have value.
Industry:Telecommunications
The switch or network to which a subscriber's directory number has been ported.
Industry:Telecommunications
The specification and arrangement in physical locations of actual communication and information system components which implement the topology.
Industry:Telecommunications
The temperature of a hypothetical resistor at the input of an ideal noise-free receiver that would generate the same output noise power per unit bandwidth as that at the antenna output at a specified frequency. Note 1: The antenna noise temperature depends on antenna coupling to all noise sources in its environment as well as on noise generated within the antenna. Note 2: The antenna noise temperature is a measure of noise whose value is equal to the actual temperature of a passive device.
Industry:Telecommunications
The technical assessment of a system or system component to determine how effectively operating objectives have been achieved.
Industry:Telecommunications
The time between (a) the instant at which a user data unit, such as a character, word, block, or message, is made available to a network for transfer by a transmitting data terminal equipment (DTE) and (b) the receipt of that complete data unit by a receiving DTE.
Industry:Telecommunications
Timing in which one station or node supplies the timing reference for all other interconnected stations or nodes.
Industry:Telecommunications
To shift the contents of a register or a field so that the significant character at the specified end of the data is at a particular position. 2. To align text horizontally or vertically so that the first and last characters of every line, or the first and last line of the text, are aligned with their corresponding margins. Note 1: In English, text may be justified left, right, or both. Left justification is the most common. Note 2: The last line of a paragraph is usually only left justified. 3. To align data on a designated character position.
Industry:Telecommunications
The time interval from removal of rf energy at the local receiver input until the local transmitter is automatically keyed on and the transmitted rf signal amplitude has increased to 90% of its steady-state value. An Exception: High-frequency (HF) transceiver equipment is normally not designed with an interlock between receiver squelch and transmitter on-off key. The transmitter can be keyed on at any time, independent of whether or not a signal is being received at the receiver input.
Industry:Telecommunications
The structure of a video signal wherein the R', G', and B' signals are kept separate from one another or wherein luminance and two bandlimited color-difference signals are kept separate from one another. Note: The separation may be achieved by separate channels, or by time-division multiplexing, or by a combination of both.
