A test to determine whether a value conforms to specified criteria.
Note: A reasonableness check can be used to eliminate questionable data points from subsequent processing. Synonym wild-point detection.

An action that re-establishes the communication with a participant of the conference. [T1.647-1995]

See receive objective loudness rating.

The ratio in dB of the voltage entering a loop and telephone to the sound pressure produced by the telephone's receiver. [After T1.255-1997]

Pertaining to a device or a mode of operation capable of receiving messages, but not of transmitting messages.

The time interval between (a) the instant of keying off the local transmitter to stop transmitting and (b) the instant the local receiver output has increased to 90% of its steady-state value in response to an rf signal from a distant transmitter.
Note 1: The rf signal from the distant transmitter must exist at the local receiver input prior to,… (Read More →)

1. The calculated or measured noise power, within the bandwidth being used, at the receive end of a circuit, channel, link, or system.
2. The absolute power of the noise measured or calculated at a receive point.
Note: The related bandwidth and the noise weighting must also be specified.
3. The value of noise power, from all sources, measured at… (Read More →)

The signal level at a receiver input terminal.
Note 1: The signal bandwidth and the established reference level must be specified.
Note 2: The RSL is usually expressed in dB with respect to 1 mW, i.e., 0 dBm.

The sink or terminator of any signal on a transmission medium. [T1.408-1990]

The time interval from (a) the instant a step rf signal, at a level equal to the receiver threshold of sensitivity, is applied to the receiver input to (b) the instant the receiver output amplitude reaches 90% of its steady-state value.
Note: If a squelch circuit is operating, the receiver attack-time delay includes the time for the receiver to break… (Read More →)
