Description:

This is the MIB Module for Cable Spectrum Management for
DOCSIS-compliant Cable Modem Termination Systems (CMTS).

Spectrum management is a software/hardware feature provided
in the CMTS so that the CMTS may sense both downstream and
upstream plant impairments, report them to a management
entity, and automatically mitigate them where possible.

The CMTS directly senses upstream transmission errors.It
may also indirectly monitor the condition of the plant by
keeping a record of modem state changes. It is desireable
to perform these functions without reducing throughput or
latency and without creating additional packet overhead on
the RF plant.

The purpose of cable Spectrum Management is to prevent long
term service interruptions caused by upstream noise events
in the cable plant. It is also used for fault management
and trouble shooting the cable network. When modems are
detected to go on-line and off-line by flap detectors, the
cable operators can look at the flap list and spectrum
tables to determine the possible causes.
