NOTE:
The TID of the far-end system is the TID listed in the Description
column of the near-end Active Alarm and Status Report
obtained using the rtrv-alm: command.
NOTE:
In a path protection switched ring network, FAILED Communication
Status most likely indicates a total node failure (power failure, failure of
both OLIUs or both fiber pairs). In a linear or hub configuration, it most
likely indicates a failure of both service and protection paths between the
last shelf without communication failure and the first shelf with a
communication failure.
NOTE:
If any systems have a Communications Status of FAILED,youmayhave
to log in to the system nearest to the system with a FAILED
communications status or issue a trouble report on the system you
cannot log into.
NOTE:
The far-end alarms refer to alarms in the same alarm group as the local
network element. For systems you cannot log into (FT-2000), issue a
trouble report on the system indicated in the Active Alarms and
Status Report.
If possible, enter the rlgn:TID command to log in to any far-end system
indicatedinthetopentryintheActive Alarms and Status Report (for
example,
MINOR farend MM-DD HH:MM:SS - SiteXNE1)
