Erlang traffic measurements are made in order to help telecommunications network designers understand traffic patterns
within their voice networks. This is essential if they are to successfully design their network topology and establish the
necessary trunk group sizes.
Erlang traffic measurements or estimates can be used to work out how many lines are required between a telephone system
and a central office (PSTN exchange lines), or between multiple network locations.
