DDM-2000 OC-12 host shelf with proper software. Verify that the
DDM-2000 OC-3 shelf is equipped with TARP Release 15 ring
software.
3. Determine the optical loss of each optical span from office records
or by making the required measurements.

NOTE:
The rtrv-eqpt: command retrieves the Equipage and
Version Report. This report lists the circuit pack type
and version information for one or more slots. See the
Commands and Reports section of this manual for a
description of the rtrv-eqpt: command format.
NOTE:
If work order or office records do not specify OLIU types,
refer to 363-206-200, DDM-20000 OC-3 and OC-12
Multiplexers, Applications, Planning, and Ordering Guide
and/or 363-206-285, DDM-2000 OC-3 Multiplexer, TARP
Release 13 and Later, User/Service Manual—Volume I . 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 slots (A, B, C, or D) 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 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.
