If a loss of connection occurs between the TX and RX ports on the local
AT-LX3800U system and the TX and RX ports on the remote AT-LX3800U
system, the links are dropped between all SFPs on the local system and
all SFPs on the remote system. This type of MissingLink implementation is
shown in Figure 45.

Figure 45. MissingLink Example #2

The value of this type of network monitoring and fault notification is that
you can configure some switches to take a specific action when a
connection is lost. In some cases, you can configure the unit to seek a
redundant path to the disconnected node and send out a trap to a network
management station, alerting the network administrator of the problem.

The color and state of the Trib and Line groups of LEDs for each line card
in an AT-LX3800U system are affected by the status of the MissingLink
settings. For information about the LEDs, refer to “LEDs” in Chapter 1,
“Overview” in the AT-LX3800U Multi-Service Transport System Installation
and Maintenance Guide
