Single-Homed Interworking Application

Figure 9-7 shows a single-homed FiberReach configuration. A single DDM-2000
OC-3 shelf provides the point of interconnection between the two rings. On the
OC-3 shelf, traffic from one ring is cross-connected through a 0x1 interface to one
direction on the other ring. The OC-3 shelf requires two OC-1 OLIUs in a function
unit to interface both sides of the FiberReach ring. No line or path protection
switching is performed for the 0x1 interface. Path protection switching is
performed at the exit points as in the simple ring application previously discussed.
