Test Your Connection’s Capacity

  3. On the Visualware BCS page, click on the Download link for Windows, Mac, or Linux. You may click on the Installation Help beside the link for assistance on installing the tool.
  4. Set the following options then click on Start Test to begin the capacity test.
    Advanced Options:
    Download bandwidth starting point (Mbps) – Choose how much download bandwidth the test will begin with. Try to choose a number that is close to what you believe you have subscribed to from your ISP.
    Upload bandwidth starting point (Mbps) – Choose how much upload bandwidth the test will begin with. Try to choose a number that is close to what you believe you have subscribed to from your ISP.
  5. The test will take several minutes. Once completed, it will show the total number of phone connections your ISP can support simultaneously.

If this connection will be used for other Internet traffic as well, run the test while there is a normal to high amount of this other traffic present. This will more accurately simulate a real deployment of our phones on this connection. You may select 1-20 simultaneous calls on your test, then click Start Test to begin the quality test.
