Advanced Spectrum Management for the Cisco uBR10012 Router
This section provides an excerpt from a typical configuration example for a Cisco uBR10012 router
using the Cisco uBR-LCP2-MC16S cable interface line card. This configuration does the following:
• Configures four spectrum groups with a hop period of 30 seconds.
• Creates a QPSK modulation profile and assigns it to four upstreams on the
Cisco uBR-LCP2-MC16S cable interface line card in slot 6/1/0.
