NOTE:
Unused optical connectors on
OLIU
s should remain looped
until optical line connections are made.
At the near end OC-12 host node, remove the optical loop from
the
FUNCTION UNITS OLIU
being used for the OC-3 ring
configuration (for example, in Figures 3 and 5, OC-12 shelf Node
5, slot
FUNCTION UNITS A 1
) At the other end of the optical span
being established, remove the optical loop from the associated
28-Type OLIU
(for example, in Figures 3 and 5, FiberReach OC-3
shelf Node 7
MAIN-1 OLIU
.

NOTE:
The section data communication channel (DCC), used for far
end communications, must be enabled at each network
element (shelf) optical interface being tested in order for the
end-to-end line tests to work. Default condition for the DCC
channel is "enabled". If it has been disabled, use the
set-fecom: command
at each shelf
to enable far end
communications.
At each shelf, use the set-fecom: address :com=enabled
command to ensure far end communications (fecom) is enabled.
19.
NOTE:
Shelves that are part of a subnetwork being partitioned into
multiple sreas require that the NSAP
AREA
field and level 2
IS-IS routing parameters of the ent-ulsdcc-l3 command
be set. See Section 11 “Commands and Reports” in
363-206-295, DDM-2000 OC-12 Multiplexer, TARP Release
7, User/Service Manual - Volume I and this manual, for an
explanation of the command parameters and 824-102-144,
Lucent Technologies 2000 Product Family, Operations
Interworking Guide for TARP Releases , for an explanation of
the engineering rules for subnetworking partitioning.
Use the ent-ulsdcc-l3 command to designate the NSAP
AREA
field and level 2 IS-IS routing, as required.
