Trunk Analyzer report.

[iSDX]

Can anyone tell me how the trunk analyser report is calculating the values for,
“Needed Trunks” and “Recommendation” in relation to the values given in the report.
Is there any documentation on how ASA runs and calculates the values in the report?

This probably doesn't pertain to this cuz I have no idea how ASA figures this out, but below is how to do it by hand. I suspect ASA does something similar

The Trunk Group Summary Report is mainly used to determine if a trunk group is sized properly. The number in the TOTAL USAGE column on the busiest day for the trunk group can be compared to the retrial table to determine how many trunks are needed. If a trunk group has no usage, the existence of the trunk group should be questioned. Also, you want to look at the OUT SRV (Out of Service) column to see if any trunks were out of service during the study. Advise the account team of any out of service trunks. The GRP OVER FLOW (Group Over Flow) column should also be reviewed. If there is data in this column, the trunk group is over flowing to another trunk group to help handle the usage. The route patterns should be reviewed before you add any additional trunks.

Thanks for the reply Jaymzter, good web site.
Does anyone else have any idea how the calculation is done, I have run trunk analyser from ASA and need to be able to explain the figures, which I presented in a quaterly report.

I think ASA uses the ERLANG algorithm to calculate the traffic report. Here is a cool website that explains more about ERLANG:
