Figure 2-28 and Figure 2-29 show two typical applications in a metropolitan high-
rise, where an OC-3 point-to-point folded ring topology network runs from the CO
to the customer's building. Figure 2-28 shows an initial application with
preexisting copper wiring in the building risers. From a basement cabinet, the
DDM-2000 OC-3 Multiplexer and DDM-Plus or DDM-2000 FiberReach provide
direct DS1 service over this wiring to cabinets on the floors above.
