NOTE:
Multiple FiberReach OC-3 shelves are allowed in this
dual-homed configuration.
NOTE:
In dual homing configurations, OLIU circuit packs must be
installed in the correct FUNCTION UNITS slots in the host
OC-12 nodes to support the direction of traffic required. For
example, see Figures 1, 2, 5, and 6. In Figures 1 and 5, if an
OLIU is installed in Node 5, FUNCTION UNITS group A, slot
1, traffic will be routed toward Node 6 when cross
connections are made. The other end of the associated
OC-3 ring must be connected to an OLIU installed in slot
2(P) of the FUNCTION UNITS group ( ) being used to
terminate the OC-3 line (for example, Node 4 in Figures 1
and 5). Traffic from Node 4 will then be directed toward
Node 3 when cross-connections are made. In Figures 2 and
6, note that all traffic from the OC-3 shelf will be directed to
Node 8 because of the slot positions that terminate the OC-3
line.
NOTE:
A dual-homed ring configuration requires that the first
FiberReach OC-3 MAIN-1 OLIU connect to FUNCTION
UNITS ( ) 1 OLIU on one host OC-12 shelf. The last
FiberReach OC-3 MAIN-2 OLIU connects to the FUNCTION
UNITS ( ) 2(P) OLIU on the other host OC-12 shelf.
Intermediate FiberReach OC-3 shelves on the same
FiberReach OC-3 ring connect from MAIN-2 OLIU at one
FiberReach OC-3 shelf to the MAIN-1 OLIU at an adjacent
FiberReach OC-3 shelf (node). For example, see Figures 3
and 5. This procedure will establish the ring configuration
starting from one OC-12 host node (near end) and
continuing to an adjacent FiberReach OC-3 node, then to
the next FiberReach OC-3 node until the final connection is
made from the last FiberReach OC-3 node to the remaining
OC-12 host node.
