NOTE:
If a program installation is being performed to a SYSCTL at the far end, it
is normal for the FAULT LED on the near-end OHCTL to flash and the MJ
and NE ACTY LEDs to light on the User Panel. If there is a MJ alarm at
the end receiving the program, trouble is indicated. You should check if a
program installation is being done.
Is new software generic being downloaded (program upgrade) to the SYSCTL
at the far end terminal?
If YES, then STOP. YOU HAVE COMPLETED THIS PROCEDURE.
If NO, then continue with Step 13.
13. In alarm report, is there any indication of OLIU or fiber trouble at near end or
far end such as inc. OC3 FERF or inc. OC12 FERF alarm message?
If YES, then continue with Step 14.
If NO, then proceed to Step 16.

NOTE:
If there is a DCC failure, a remote login to the shelf connected through
the Source Address cannot be done. The rtrv-alm:,
rtrv-map-network:, and rtrv-map-neighbor: commands can be
used to check for DCC failure for MAIN (and FUNCTION UNITS A, B, or
C). Also, use rtrv-fecom: command to see if fecom has been
disabled.
Note Source Address of DCC channel failure. Check optical fibers
connected through the Source Address per local procedures. If no trouble
found, replace near-end OLIU first then far-end OLIU.
