At the near end OC-3 or OC-12 host node, remove the optical
loop from the 26G2-U, 27G-U or 27G2-U OLIU OC-1 line (1 or 2)
being used for the OC-1 ring configuration (for example, in
Figures 7 and 8, OC-3 shelf Node 5, slot FUNCTION UNITS-A-1,
OC-1 line 1.) At the other end of the optical span being
established, remove the optical loop from the associated OLIU.
(For example, in Figures 7 and 8, FiberReach MAIN-1 OLIU.)
11.
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.
12. Perform optical fiber connections and verification of the integrity of
the optical span being established.
13.
NOTE:
Shelves that are part of a subnetwork being partitioned into
multiple areas require that the NSAPAREA field and level 2
IS-IS routing parameters of the ent-ulsdcc-l3:
command be set. See Section 11, Commands and Reports
in 363-206-285, DDM-2000 OC-3 Multiplexer, TARP Release
13 and Later, User/Service Manual—Volume I and
363-206-305, DDM-2000 FiberReach Multiplexer,
Wideband/Narrowband Shelf, TARP Release 3 and Later,
User/Service 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
subnetwork partitioning.
Use the ent-ulsdcc-l3: command to designate the
NSAPAREA field and level 2 IS-IS routing, as required.
