Erlangs to IP bandwidth calculator

Print this Topic Previous pageReturn to chapter overviewNext page

 

This calculator takes the VoIP bandwidth calculation in the Lines to IP bandwidth calculator a step further.  Rather than taking the number of lines as its input, it takes the Busy Hour Traffic (in Erlangs) as its input.  Full control over the VoIP parameters is offered, as described for the previous calculator.  In addition, the Erlang B Calculator block lets you choose the desired blocking figure; that is, the percentage of calls which may be blocked because insufficient facilities have been provided.
