OC-3 Ring Transport on OC-12 Point-to-Point
2
Rings that cover a large geographical area or interconnected path switched rings
are a cost effective and popular way for a service provider to offer these high
priority services. Figure 2-8 shows a ring configuration using DDM-2000 OC-3
ring nodes with DDM-2000 OC-12 point-to-point nodes to provide a high-service
availability architecture. This configuration will survive fiber, equipment, and
catastrophic office failure, since it provides an alternative service path through a
secondary CO and uses the path switching ability of the DDM-2000 OC-3 to
select between these two paths. In this example, the OC-12 NEs are connected
as folded rings in a point-to-point configuration; 0x1 cross-connects are used to
connect with the OC-3 rings.
