Figure 2-3 shows how DDM-2000 OC-3 and OC-12 Multiplexers can be used
together to provide a path switched ring operating simultaneously at the VT1.5,
STS-1, and STS-3c levels. This ring is especially useful for loop feeder
applications with large bandwidth needs. It can also be developed as a result of
an upgrade from an OC-3 ring in an environment where growth has exhausted the
bandwidth of the OC-3 ring.
