When you start the Traffic Calculators, a window will appear with four tab controls at the top. Select the tab Erlang C.
The Erlang C Calculator
The calculator is divided into two sections. The top section is for the entry of variables describing the quantity of calls received by a group of operators. The bottom section describes the queuing and delay characteristics of a group of operators. Each quantity has a radio button associated with it which is used to show which quantity is unknown and to be calculated.
Common to all three calculators, there are five buttons on the right hand side of the window. Click here for information regarding their use.
When entering figures into the edit boxes, a full stop or period should be used as a decimal mark, NOT a comma as is the convention in some European countries.
