NOTE:
In dual homing configurations,
OLIU
circuit packs must be
installed in the correct slots in the host OC-3/OC-12 nodes to
support the direction of traffic required. For example, see
Figures 1 and 2. In Figures 1 and 2, if a
27-Type OLIU
is
installed in Node 5,
FUNCTION UNITS

A
, slot

,
traffic will be routed toward Node 6 when cross-connections
are made. The other end of the associated OC-1 ring must
be connected to a
27-Type OLIU
installed in slot
2(P)
of the
FUNCTION UNITS
GROUP
( )
being used to terminate the
OC-1 line (for example, Node 4 in Figures 1 and 2). Traffic
from Node 4 will then be directed toward Node 3 when
cross-connections are made. In Figures 3 and 4, note that
all traffic from the FiberReach shelf will be directed to Node 7
because of the slot positions that terminate the OC-1 line.
NOTE:
A dual-homed ring configuration requires that the first
FiberReach
MAIN-1 OLIU
connect to
FUNCTION UNITS ( )
1 OLIU
on one host OC-3 shelf. The last FiberReach
MAIN-2 OLIU
connects to the
FUNCTION UNITS ( ) 2(P)
OLIU
on the other host OC-3 shelf. Intermediate
FiberReach shelves on the same OC-1 ring connect from
MAIN-2 OLIU
at one FiberReach shelf to the
MAIN-1 OLIU
at an adjacent FiberReach shelf (node). For example, see
Figures 7 and 8. This procedure will establish the ring
configuration starting from one OC-3/OC-12 host node (near
end) and continuing to an adjacent FiberReach node, then to
the next FiberReach node until the final connection is made
from the last FiberReach node to the remaining OC-3/OC-12
host node.
NOTE:
All unused ports on the
27-Type OLIU
must be set to nmon
with the set-state-oc1 command.
