FX LinkLoss (FXLL)

FX LinkLoss is a link integrity monitoring feature that forwards fiber link faults to the RJ-45 DATA port to indicate that a fiber link fault has occurred. FX LinkLoss can be enabled in iView².

Link Fault Pass-Through (LFPT)

Link Fault Pass-Through (LFPT) is a troubleshooting feature that passes a link fault from the Ethernet port on one module through to the Ethernet port on the other module. LFPT can be enabled via iView² or through the console port.

The link fault is passed through the media conversion and is observed at each end. It acts just as it would if the end devices were directly connected without a fiber link.

E1 Ports Setup

Alarm Level

E1 lines are defined as LOST when no signal is received as defined by ITU G.775 specifications LOS, and are considered in error with a BER of 10^-6. If either of these conditions lasts for more than 2.5 seconds, an ALARM state is declared. This error condition must be absent for 10 seconds for the alarm state to clear.

The starting and ending event of all alarm conditions will generate an SNMP TRAP when the unit is installed in a managed chassis and set to the IS state. During initial installation or normal maintenance, the end-user can place the unit in the OOS (Out- Of-Service) state to inhibit unwanted SNMP TRAP alarms.
