Motorola BSR 2000 manual Cable modulation-profile

Release 1.0 CMTS Commands

cable modulation-profile

The cable modulation-profilecommand navigates to Modulation Profile Configuration Mode. Modulation Profile Configuration Mode provides a series of modulation profile commands that allow an MSO to create or modify a modulation profile.

Warning: Motorola does not recommend modification of modulation profile parameters without a thorough understanding of modulation changes and DOCSIS interface specifications. Modulation profile parameters will affect the physical layer and may cause disruption or degradation of services.

Note: Modulation profiles 1-4, 101-116, 201-205, and 301-310 are pre-configured modulation profiles. To view the configuration of these profiles, use the show cable modulation-profilecommand.

Motorola recommends that user-created modulation profiles use the numbering range of 401-600 to ensure better future portability.

For a complete list and configuration of all 23 pre-defined modulation profiles, refer to Appendix A, Pre-Defined Modulation Profiles in the BSR 64000 Configuration and Management Guide.

For guidelines on modifying modulation profile parameters, refer to Appendix B, Understanding and Modifying Modulation Profiles in the BSR 64000 Configuration and Management Guide.
