Loopback Test Activates a loopback test on the specified port.
• Local Loopback (LLB): Can be used to check the source of a certain problem.
Activates the local loopback on the local data port. Checks that the user's equipment
receives its own signal while the loopback is connected. If it does, the problem is
external.

example, if there is certain alarm on a port, and if after activating the RLB the alarm
disappears, then the problem is external.
• None: No Test.
