DDM-2000 OC-3 MULTIPLEXER
DO ITEMS BELOW IN ORDER LISTED . . . . .FOR DETAILS, GO TO
DLP-5312. Verify that the host DDM-2000 OC-12 shelf is equipped with TARP
Release 7 or later ring software. If not equipped with TARP
Release 7 or later software, upgrade the DDM-2000 OC-12 host
shelf with proper software. Verify that the DDM-2000 OC-3 shelf is
equipped with TARP Release 13 or later 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,

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 (FN A, FN B, FN C,orFN 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.
