Data
The Trunk Required Forecast generates a table that tells you how many
4
calls per intrahour interval can be handled by variable numbers of trunks.
The trunk blocking probability and holding time per call that you specify
also affect the number of calls that the trunks can handle.
The Trunks Required Forecast is a quick calculator that lets you see how
adjusting the number of trunks can affect your center's call handling
efficiency.
The Trunks Required Forecast, in addition to calculating the number
of calls handled for each number of trunks, tells you what the usage
rate of your trunks will be.

The forecast presents the usage rate in Erlangs. An Erlang is 100%
occupancy of one trunk in a given time frame — for this forecast, the
length of your intrahour interval. If the forecast shows a usage rate
of 7 Erlangs and your intrahour interval is 30 minutes, this means
the trunk occupancy of all trunks added together would equal 210
minutes (7 times 30 minutes). If your intrahour interval were 15
minutes, 7 Erlangs would equal a total trunk occupancy of 95
minutes.
Therefore, you could think of 7 Erlangs as equivalent to 7 trunks
occupied for the whole intrahour interval. Or, from a different
perspective, you could think of 7 Erlangs as meaning that an
average of 7 trunks will be in use at any given time in the interval.
You can run a forecast for a specific number of trunks or a range of
trunks.
If you specify a range of trunks (for example, 100-200), you will get
a table with 101 rows, one row for each increment of one trunk.
However, you can choose to have only gradations of trunks listed.
For example, instead of having 101 rows (100 to 200) in your report,
selecting gradations will cause the forecast to list increments of
trunks according to a fixed algorithm (perhaps, at 100, 110, 120, and
so on).
