7.
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
, you may have
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
indicated in the top entry in the
Active Alarms and Status Report
(for
example,
MINOR farend MM-DD HH:MM:SS - SiteXNE1
)
