9.
NOTE:
A ring configuration requires that the MAIN 1 OLIU at one
shelf (node) connect to the MAIN 2(P) OLIU at an adjacent
OC-3 shelf (node). See Figures 1 and 2. It is suggested that
this procedure establish the OC-3 ring configuration starting
from the near end node and continuing to an adjacent node,
then to the next node until the final connection is made from
the last node back to the first node.
At the near end, remove the optical loop from ONE OLIU (for
example, MAIN 2(P)) associated with the optical span being
established. At the other end, remove the optical loop from the
associated OLIU (for example, MAIN 1) in the optical span being
established.
10.
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.
11. Perform optical fiber connections and verification of the integrity of
the optical span being established.
