8. Testing

Remote Send Line Loopback

The local unit initiates this test by sending a line loopback Up or Down command to the remote unit for 10 seconds. When the remote unit detects the loopback Up command, it puts itself in line loopback and lights the front panel Test LED. The remote unit remains in loopback until it receives a loopback Down command or the remote unit’s test timeout value is exceeded. The Send Line Loopback tests both units. External equipment can be used to verify the link.
