Create Circuits and VT Tunnels
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 create Cisco ONS 15327 electrical circuits, VT tunnels, optical circuits,
and Ethernet circuits. For additional information about ONS 15327 circuits, refer to the Circuits and
Tunnels chapter in the Cisco ONS 15327 Reference Manual.
