NOTE:
This single-homed ring configuration requires that the
FN-( )-1 OLIU on the OC-12 shelf connect to the MAIN 1
OLIU at the first OC-3 shelf from the OC-12 shelf. MAIN 2(P)
OLIU at the OC-3 shelf (node) connects to the MAIN 1 OLIU
at an adjacent OC-3 shelf (node). The MAIN 2(P) OLIU at
the last OC-3 shelf on the OC-3 ring connects to FN-( )-2(P)
OLIU on the host OC-12 shelf. See Figure 1. This procedure
will establish the ring configuration starting from the OC-12
host node (near end) to the first OC-3 node, then continuing
to the next node until the final connection is made from the
last OC-3 node back to the host OC-12 node.
At the near end, remove the optical loop from the OLIU (for
example in Figure 1, Node 5 OC-12 shelf FN-A-1) associated with
the optical span being established. At the other end of the optical
span, remove the optical loop from the associated OLIU (for
example, in Figure 1, Node 7 OC-3 shelf MAIN 1 OLIU).
18.
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. Perform optical fiber connections and verification of the integrity of
the optical span being established.
