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 13-4 shows 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.
