CMTS Commands

 

 

cable upstream frequency

The cable upstream frequency command sets the fixed frequency for the upstream cable port in Hz. The no cable upstream frequency command returns the default upstream frequency value. The cable interface does not operate until a fixed upstream frequency is set. The RF upstream frequency must comply with the expected CM output frequency.

Note: The Japan DOCSIS Standard must be specified with the cable cmts type command before an upstream frequency can be selected for any Japan DOCSIS Standard CMTS module.

Note: Make sure that the upstream frequency selected does not interfere with the frequencies used for any other upstream applications running in the cable plant.
