Another integrated narrowband business carrier access application option for the
DDM-2000 FiberReach narrowband shelf is to collocate it with the DDM-2000
OC-3/OC-12 shelf. Since the narrowband shelf's high-speed interface is a DS1, a
DDM-2000 OC-3/OC-12 multiplexer can serve as the ring vehicle for carrying the
DS0 traffic. This application is shown in Figure 2-45.
