In telecommunication, a call-second is a unit used to measure communications traffic density, equivalent to one call with a duration of one second. Traffic is measured independent of users. For example, one user making two 75-second calls is equivalent to two users each making one 75-second call, as each case produces 150 call-seconds of traffic. A CCS (centacall-second) is often used to describe 100 call-seconds, so 3600 call-seconds = 36 CCS = 1 call-hour. In a communication network, a trunk (link) can carry numerous concurrent calls by means of multiplexing. Hence a particular number of call-seconds can be carried in infinitely many ways as calls are established and cleared over time. For example, one call-hour could be one call for an hour or two (possibly concurrent) calls for half an hour each. Call-seconds give a measure of the average number of concurrent calls. Offered load is defined as the traffic density per unit time, measured in erlangs. An erlang is defined as one call-hour per hour, or 3,600 call-seconds per hour. Hence, if one CCS is measured over a one-hour period, the offered load is 1/36 erlangs. (Wikipedia).
If I'm running even 1 minute late for my dog's morning walk...
I take my dog for a long walk every morning. Anytime I'm running late, this is how he acts. Also, he'd already been let out once to do his business. This is before his longer walk to tire him out before I leave for work. He's not about to explode... just excited.
