Preface
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.
