This tab control has two tabs, each representing a calculator included with the programme: Lines and IP Bandwidth Calculator and Erlangs and IP Bandwidth Calculator. Select the required tab representing the calculator with which you wish to work.

The B/W units radio buttons are used for both calculators to select whether entries and results are made and displayed using kbps or Mbps.
