DSG: New DOCSIS Option Can Consolidate Administration of the Data Network,
Continued
If your network uses both QPSK modulators and CMTSs to feed a given set-top
population, the DCM for these associated QPSK and CMTS bridges must be set to
the same value. If you want the DOCSIS-capable set-tops in the set-top population to
run in DOCSIS mode, all DCMs for bridges serving the set-top population must be
set to DOCSIS. Any DAVIC-only set-tops in the population will ignore the DOCSIS
DCM; however, DOCSIS-capable set-tops require the DOCSIS DCM in order to run
in DOCSIS mode.
The following diagram provides a simplified example of this concept.
