connected to the fiber optic port that the connection on the twisted pair
port has been lost. If the failure had started with the fiber optic cabling, the
line card would drop the link to the twisted pair port.
Some devices can be configured to take a specific action in the event of
the loss of connection on a port, such as sending out a trap to a network
management station to alert the network administrator of the problem.
Note
MissingLink™ is supported on all Converteon™ line cards except
the AT-CM70S.
Smart
MissingLink
The Smart MissingLink feature performs exactly the same function as
MissingLink™ with one additional feature. When a link is lost on a port, the
LK LED of the port that still has a valid connection to its end node starts to
blink. This allows you to quickly determine which port still has a valid
connection (LK LED blinking) and which port has lost its connection (LK
LED Off).
For example, if the network twisted pair cable to the 10/100Base-TX port
on the line card fails, the LK LED on the 100Base-FX fiber optic port
blinks, indicating a failed connection on the twisted pair port. If the failure
starts with the fiber optic cabling, the LK LED on the twisted pair port
blinks.
Smart MissingLink allows you to quickly see which port has failed and to
troubleshoot your network accordingly.
Note
Smart MissingLink is supported on all Converteon™ line cards
except the AT-CM70S.
OAM OAM refers to the tools and utilities to install, monitor, test, and
troubleshoot a network, helping carriers run their networks more
efficiently. Without management features to monitor and troubleshoot the
network remotely, it is expensive and time-consuming to have the
problems diagnosed and resolved by sending a technician to the location.
For detailed information about OAM, refer to Chapter 8, “Operations,
Administration, and Maintenance (OAM)” on page 111.
Note
OAM is supported only on the AT-CM2xx Series, AT-CM2K0S, and
the AT-CM70S Converteon™ line cards.
