What is tmnxSonetTxDus?

This object controls whether the SONET S1 overhead byte transmits a special marker (0xF or 'dus/dnu') that indicates degraded or non-operational status on a SONET interface. Setting this to true forces that marker into outgoing SONET frames for testing or to signal a controlled shutdown. An operator would use this during maintenance windows or to force SONET endpoints to treat the link as unavailable.
