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).

Testimonials

Instructor made sure material being covered was relevant to our job requirements. Allowed the class to dictated topics covered.

Instructor allowed conversation of topics to drift into real-world applications.

The instructor and the material fully met my expectations and the needs of the team

His knowledge of the industry as well as training methods made the class very effective.

Having spent years studying learning theories, I was impressed with the instructor's ability to make class a success.

As someone who processes the direct telecom bills for Facilities I was able to gain a better understanding of what SS7 is, how it relates to the work our engineers do (especially calculating trunks needed), and will trunks needed), and will be able hopefully to recognize its coding on our invoices.

The instructor was obviously very knowledgable on the subject matter and yet was able to explain it in terms that even I, not being an engineer, could easily understand.

I thought the instructor was an excellent instructor. I learned a lot. Thank you.
