In telecommunication, a call-second is 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 Call-second = 36 CCS per hour = 1 call-hour per hour = 1 erlang = 1 traffic unit.

Electronics Topics
The field of electronics is the study and use of systems that operate by controlling the flow of electrons or other electrically charged particles in devices such as thermionic valves and semiconductors. The design and construction of electronic circuits to solve practical problems is part of the fields of electronic engineering, and the hardware design side of computer engineering. The study of new semiconductor devices and their technology is sometimes considered as a branch of physics.
