Chapter 1 System Overview
System and Network Management
For the most comprehensive set of monitoring and management capabilities, use the in-band message
channel, SONET DCC, and OSC on your network. The in-band message channel and SONET DCC
provide fault isolation and monitoring at the wavelength level, and OSC provides that functionality for
the fiber.
