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.
A unit used to measure communications traffic. Note 1: A call-second is equivalent to 1 call 1 second long. Note 2: One user making two 75-second calls is equivalent to two users each making one 75-second call. Each case produces 150 call-seconds of traffic. Note 3: The CCS, equivalent to 100 call-seconds, is often used. Note 4: 3600 call-seconds = 36 CCS = 1 call-hour. Note 5: 3600 call-seconds per hour = 36 CCS per hour = 1 call-hour per hour = 1 erlang = 1 traffic unit.
Industry:Telecommunications
The luminous intensity in a specified direction, of a monochromatic source which has a frequency of 540 x 1012 Hz and which has a radiant intensity, in the specified direction, of (1/683) watt per steradian.
Industry:Telecommunications
A phenomenon, associated with FM reception, in which only the stronger of two signals at or near the same frequency will be demodulated. Note 1: The complete suppression of the weaker signal occurs at the receiver limiter, where it is treated as noise and rejected. Note 2: When both signals are nearly equal in strength, or are fading independently, the receiver may switch from one to the other. Synonym FM capture effect.
