To Iovekesh mehta:

The online Erlang calculation of a GSM switch (can be any other like Siemens EWSD 13 or 15)is performed
by a simple algorithm:

A counter/timer is assigned for every trunk group processor (or equivalent at any switch). This counter/timer adds every seizure time (conversation+signalling) and report the utilization ration within a period of 60 seconds, resetting after this.

At the core processor, and reporting to the management system, an utility program add every reported time and divides it by the full available time across all line-trunk groups enabled at the switch. It’s an useful reference for ‘real time’ load at the switching matrix.
