This tool was developed for call centers to optimize service performance, based on the Erlang traffic model. We used this model to calculate the number of Low-Speed Links (LSLs) required to support a specified number of CAMEL transactions, as depended on transaction size (in bytes). Our calculator also provides the number in SIGTRAN bandwidth.
No. of subscribers in the network:
Average number of calls per subscriber per hour (BHCA):
No. of CAMEL transactions per second in your network:
Enter the number of subscribers in the network (or the number of subscribers you would like to support), and the number of calls per subscriber per hour taking place (Busy Hour Call Attempts – BHCA) and hit the “Calculate” button.
The Erlang C formula provides a way to calculate the probability that a caller waits for an agent, given a particular traffic intensity and the number of available agents.
