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
Multiplexers, Applications, Planning, and Ordering Guide
and/or Volume 1 of this User/Service 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 OC-12 node, verify/install OLIU circuit packs in FUNCTION
UNITS slots (FN A, FN B, FN C, or FN D) being used for the new
OC-3 extension. (OC-12 Reference: 363-206-295, DDM-2000

NOTE:
21G/21G-U OLIU circuit packs are used in the OC-12 shelf,
the HIGH/LOW POWER switch must be set to LOW before
connecting the optical loops. The 21G2-U/21G3-U OLIU
does not require an LBO for shelf loopback.
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.
Connect optical loops for FUNCTION UNITS OLIUs just installed.
