If a remote loopback test is performed, data is transmitted from the local site to a remote site, and then back to the local site. Table 13-4shows the available loopback tests on the terminal and their objectives.

To enable the terminal to communicate with other terminals properly, the loopback test must be stopped.

A remote video loopback test cannot be performed during a dual-stream conference.
