Hi,
I am looking for the Erlang B formula and the theory behind it. I would be grateful if anyone who has this information to let me know.
Thanks,
Jose Quintero Guest
Steve,
The erlang B formula is well describe in the Book Digital telephony form Jhon Bellami.
Bassicaly is a poisson formula.
if you want the formula I am be able to provide it to you.

Erlang C is a model where blocked calls are queued. This formula is traditionally used in call center environments.
2,5 Erlangs is the amount of traffic carried/offered to traffic sensitive facilities.
In order to get usable numbers you still need GoS and delay factor.

Hi Jose,
I will check out the book you mention. Meanwhile if you have the formula(ae) I would be grateful if you could send it to me at: scain@lucent.com
many thanks,
Steve

Here are a couple of links that will give you some background to Erlang. I thought I had a copy of the formula but I can’t seem to put my hands on it right now. If I do I will post it.

Rommel & Chris Wood: thank you very much.

Or you can use the poisson function of Excel to find blocking:
=(POISSON(,,FALSE))/(POISSON(,,TRUE))
where = # of servers
= BHT load in erlangs

I have seen several addins for Excel that utilize the Erlang B model. I have downloaded and tried two different variations of the addin, and neither one seem to provide me with the answer I was looking for. Does anyone have a source for a reliable and accuarate Erlang B add in?
I need it to help calculate bandwidth when traffic and blcking are known, as well as to estimate Minutes of usage per day…
