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 average value of the duration of a successful block transfer attempt. Note: A block transfer attempt is successful if (a) the transmitted block is delivered to the intended destination user within the maximum allowable performance period and (b) the contents of the delivered block are correct.
Industry:Telecommunications
The average value of elapsed time between the start of a disengagement attempt for a particular source or destination user and the successful disengagement of that user. 2. Elapsed time between the start of a disengagement attempt and successful disengagement.
Industry:Telecommunications
The average ratio of user information bits to total bits in successfully transferred blocks.
Industry:Telecommunications
The average power supplied to the antenna transmission line by a transmitter during one radio frequency cycle taken under the condition of no modulation. Note: The concept does not apply to pulse modulation or frequency-shift keying. 2. The average unmodulated power supplied to a transmission line.
Industry:Telecommunications
The average power supplied to the antenna transmission line by a transmitter during one radio frequency cycle at the crest of the modulation envelope taken under normal operating conditions.
Industry:Telecommunications
The average power supplied to the antenna transmission line by a transmitter during an interval of time sufficiently long compared with the lowest frequency encountered in the modulation taken under normal operating conditions. Note: Normally, a time of 0. 1 second, during which the mean power is greatest, will be selected.
Industry:Telecommunications
The average number of units of data, such as bits, characters, blocks, or frames, transferred per unit time from a source and accepted as valid by a sink. Note: The effective data transfer rate is usually expressed in bits, characters, blocks, or frames per second. The effective data transfer rate may be averaged over a period of seconds, minutes, or hours.
Industry:Telecommunications
The average number of bits, characters, or blocks per unit time passing between corresponding equipment in a data transmission system.

The attribute of an optical fiber, the cross section of the core or cladding of which deviates from a perfect circle. 2. In an optical fiber, the degree of deviation, from perfect circularity, of the cross section of the core or cladding. Note 1: The cross sections of the core and cladding are assumed to first approximation to be elliptical. Quantitatively, the ovality of either the core or cladding is expressed as 2 (a-b) / (a+b,) where a is the length of the major axis and b is the length of the minor axis. The dimensionless quantity so obtained may be multiplied by 100 to express ovality as a percentage. Note 2: Alternatively, ovality of the core or cladding may be expressed or specified by a tolerance field consisting of two concentric circles, within which the cross section boundaries must lie. Synonym noncircularity.
