Figure 2-23 also shows an optical drop/insert DS1 extension from the SONET
rings implemented with RFL 9001 Intelligent Multiplexers. This extension is useful
for serving low bandwidth sites remote from the SONET backbone. The figure
shows a single host DDM-2000 interconnecting the rings, but the application
could be a DRI to provide node survivability.
