2. Verify the host DDM-2000 OC-3 shelves (for example, Figures 1,
2, 3, and 4, nodes 4 and 5) are equipped with TARP Release 13
or later ring software. If not equipped with TARP Release 13 or
later software, upgrade the DDM-2000 OC-3 host shelves with
proper 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-2000 OC-3 and OC-12
Multiplexer, 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.
DLP-504 At the host OC-3 or OC-12 nodes, verify/install 26G2-U, 27G-U or
27G2-U OLIU circuit packs in FUNCTION UNITS slots (A, B, or
C) being used for FiberReach 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.
DLP-505 Connect optical loops for FUNCTION UNITS OLIUs just installed.
