Turn Up Network
Note 
The terms "Unidirectional Path Switched Ring" and "UPSR" may appear in Cisco literature. These terms do not refer to using Cisco ONS 15xxx products in a unidirectional path switched ring configuration. Rather, these terms, as well as "Path Protected Mesh Network" and "PPMN," refer generally to Cisco's path protection feature, which may be used in any topological network configuration. Cisco does not recommend using its path protection feature in any particular topological network configuration.
This chapter explains how to turn up and test Cisco ONS 15600s in point-to-point networks, bidirectional line switched rings (BLSRs), path protection configurations, and dual-ring interconnects (DRIs).
