In contrast to SONET / SDH where the data communication channel ( DCC ) has a constant data rate, GCC data rate depends on the OTN line rate.
2.
The overheads contain information from the transmission system itself, which is used for a wide range of management functions, such as monitoring transmission quality, detecting failures, managing alarms, data communication channels, service channels, etc.
3.
As mentioned above, the overhead of an STM-4 signal ( SOH ) is divided into two parts : the MSOH and the RSOH . The overheads contain information from the system itself, which is used for a wide range of management functions, such as monitoring transmission quality, detecting failures, managing alarms, data communication channels, service channels, etc . These functions will be described in more detail in the section on network management services.
