 Print this Topic Previous pageReturn to chapter overviewNext page

To estimate what blocking will be experienced with a given busy hour traffic figure and number of lines, use:                

 

=ErlBBlocking(x,y)

 

This function takes two parameters:

 

•x is the busy hour traffic in Erlangs
•y is the number of lines

 

For example, to estimate how the blocking experienced when 1500 Erlangs of traffic is offered to 1000 lines, enter:

 

=ErlBBlocking(1500,1000)

The answer should be 0.335

 

As with other Excel functions, you can either enter absolute values as the parameters, or you can add references to other cell on the same workbook or other open workbooks.
