NOTE:
If fecom is enabled, an
inconsistent DCC values
alarm
will occur when the OLIUs are looped back. Normally, the
alarm occurs when the user/network parameters on the
OHCTLs at both ends of the DCC are set the same. To clear
the alarm during a fiber loopback, use the
set-fecom:address:com=disable
command to disable
the DCC.
At OC-12 shelf, connect optical loops for FUNCTION UNITS
OLIUs just installed.
