A traffic volume of one erlang-hour can be caused by two circuits being occupied constantly for half an hour or by a circuit being half occupied (0.5 erlang) for a time of two hours.
TRAFFIC VOLUMES
In
telecommunication networks, traffic volume is an appraise of the total work
done by a resource or capacity, normally over 24 hours, and is measured in
units of erlang-hours.
It is defined as the product of the average traffic power
and the time period of the study.
Traffic
volume = Traffic intensity × time
A traffic volume of one erlang-hour can be caused by two circuits being occupied constantly for half an hour or by a circuit being half occupied (0.5 erlang) for a time of two hours.
Telecommunication operators are crucially interested in traffic volume, as it openly
dictates their revenue.
