NOTE:
A dual-homed ring configuration requires that the first OC-3
MAIN-1 OLIU connect to FUNCTION UNITS ( ) 1 OLIU on
one host OC-12 shelf. The last OC-3 MAIN-2(P) OLIU
connects to the FN( ) 2(P) OLIU on the other host OC-12
shelf. Intermediate OC-3 shelves on the same OC-3 ring
connect from MAIN-2(P) OLIU at one OC-3 shelf to the
MAIN-1 OLIU at an adjacent OC-3 shelf (node). For
example, see Figure 3. This procedure will establish the ring
configuration starting from one OC-12 host node (near end)
and continuing to an adjacent OC-3 node, then to the next
OC-3 node until the final connection is made from the last
OC-3 node to the remaining OC-12 host node.
NOTE:
Unused optical connectors on OLIUs 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 OC-3 OLIU being used for the OC-3 ring
configuration (for example, in Figure 3, 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 OLIU
(for example, in Figure 3, OC-3 shelf Node 7 MAIN-1 OLIU.
