Loopback Test

Loopback Test

Your endpointRP can transmit audio or video data on a channel to simulate an actual application and test whether the output is satisfactory. You can perform a local loopback test to check the local network connection or a remote loopback test to check the remote network connection. When you perform a remote loopback test, data is transmitted from your site to a remote site, and then back to your site. Table 22-2 lists the types of loopback tests available on your endpointRP.

  • To enable your endpointRP to communicate with other endpointRPs, stop the loopback test.
  • You cannot perform a loopback test on remote video if you are in a dual-stream conference.
