NOTE:
If work order or office records do not specify OLIU types,
refer to 363-206-200,
DDM-2000 OC-3 and OC-12
Multiplexers, Applications, Planning, and Ordering Guide
and/or this manual, for a description of OLIU circuit packs
and applications. Optical line power measurements and/or
office records must be used to verify that the span length can
be supported.
At the host OC-12 node, verify/install OLIU circuit packs in
FUNCTION UNITS (A, B, C, or D) slots being used for OC-3
access.
5.
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 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.
6.
NOTE:
The Network Side (NS)/User Side (US) parameters of the
set-fecom: command must be set opposite at each end
of the optical spans. For example, see Figure 2.
Use the rtrv-fecom/set-fecom command to verify/set
"Network Side/User Side" parameters at each end of optical span
being established.
7. What Release of software is installed in the OC-12 host shelf?
If Release 7 or 15 software is installed, continue with Step 8.
