Notes :
1. In this example traffic originating at the OC-3 CO node flows in one direction to Main-1 of
FiberReach host node OC-3 RT1, through its function unit slot a-1, b-1 or c-1 to Main-1
of FiberReach RT3. Likewise, traffic originating at the OC-3 CO node flows in the other
direction to Main-2 of FiberReach host node OC-3 RT2, through its function unit slot a-2,
b-2 or c-2 to Main-2 of FiberReach RT4.
2. Failure to place the 27G-U OLIUs in the correct function unit positions (for example if the
27G-Us were placed in function unit slot 2 of OC-3 RT1 and function unit slot 1 of OC-3
RT2) will result in failure of traffic flow between the FiberReach and the correct OC-3
nodes.
