Chapter 12 Convert Network Configurations; Before You Begin - Cisco ONS 15327 Procedure Manual

Convert Network Configurations
The terms "Unidirectional Path Switched Ring" and "UPSR" may appear in Cisco literature. These terms
Note
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 convert from one SONET topology to another. For initial network turn up,
see Chapter 4, "Turn Up Network."
