 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 -2Lines 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- CallCenter 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 -4Call 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 -5Erlangs 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 -6Extended 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 -7Erlang 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).
