Remote Network Send Line Loopback - Paradyne 7974 User Manual

Remote Network 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 into 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.
