So, ... What is an Erlang?
"An Erlang is a unit of traffic and queuing measurement, and an Erlang represents the continuous use of one voice path. Erlang traffic and queuing measurement are made in order to help telecommunications network designers understand traffic and queuing patterns within their voice networks. Erlang traffic measurements or estimates are used to determine how many Voice lines are required between at telephone system and a central office (PSTN/ISDN exchange lines and voice trunks) or between multiple network locations."
This is essential if they are to successfully design their network topology and establish the necessary trunk group sizes based on various factors to support your business.
The iErlang Calculator for iPad, provides a user friendly interface to the complex mathematical formulas at the heart of the erlang theory. This supports the Telecommunications professional to meet the needs of the business and correctly size for optimal business performance, the requirements of PSTN and Voice services for Telephony and PSTN services.
The iErlang Calculator functionality supports the full range of Erlang calculations including the generally used calculations :
- Erlang B, (Blocked Call Lost)
- Erlang C, (Blocked Calls Delayed)
To the Erlang Calculations required for more complex and sophisticated Voice/Telephony designs including:
- Poisson,
- Engset,
- Binomial and
- Delay.
All Erlang calculated outputs are displayed on easy to read screens in numerical or graphical formats and output results can be exported from the iPad. (Refer to Example Screen below).
System Requirements: iErlang Calculator application runs on the Apple iPad and requires Apple iPad OS4.2 and above.
