Loopback Tests
During a loopback test, your TE30 transmits audio or video data through a channel to simulate
actual working conditions and tests whether the output is satisfactory. You can perform a local
loopback test to check the network connection at your site or a remote loopback test to check
the network connection at a remote site. While a remote loopback test is being performed, data
is transmitted from your site to a remote site and then back to your site.
