 WORKSHOP (8 Hands-on Traffic Engineering Labs)
Lab -1-
Erlang B Calculator
The Erlang B Calculator can be used to work out how many lines
you need for a trunk group if you know the Busy Hour Traffic which
the trunk group is offered.
Lab -2-
Lines to IP Bandwidth Calculator
The Lines and IP Bandwidth Calculator can be used to estimate the
bandwidth required through an IP based network for a fixed
number of voice paths.
Lab -3-
Call Center Calculator
Our Call Centre Calculator, which can be used to estimate how
many call centre agents you require for each hour of an eight hour
day, and how many trunks you need.
Lab -4-
Call Minutes Calculator
The Call Minutes Calculator uses the number of minutes of traffic a
trunk group is offered in one day to work out the number of
required lines.
Lab -5-
Erlangs to VoIP Bandwidth Calculator
The Erlangs and Bandwidth Calculator can be used to estimate the
bandwidth which must be provided through an IP based to
satisfactorily transport a given busy hour traffic level.
Lab -6-
Extended Erlang B Calculator
The Extended Erlang B Calculator is similar to the Erlang B
Calculator but takes retries into account. It can be applied to trunk
groups from which no overflow facilities exist.
Lab -7-
Erlang C Calculator
The Erlang C Calculator can be used to estimate how many agents
are required in a call centre, if the quantity and length of incoming
calls are known.
Lab -8-
Engset Calculator
The Engset Calculator can be used to work out how many lines you
need for a trunk group if you know the Busy Hour Traffic which the
trunk group is offered. It should be used instead of the Erlang B
Calculator when the number of traffic sources is finite (less than ten
times the number of lines).
