Description
Specifies an upstream channel width for a headend cable router.
Enables the upstream FEC.
Disables optimum frequency hopping on the Cisco uBR-MC16S and
Cisco uBR-MC5X20S/U cable interface line cards.
Overrides modulation types specified in the modulation profile for the
specified upstream channel.
Specifies the upstream port number. Valid values start with 0 for the
first upstream port on the cable interface line card.
Overrides the FEC strength specified in the modulation profile for
this upstream channel. Valid values are from 0 to 10, where:
0 disables FEC.
•
1 is the lowest FEC strength.
•
10 is the highest FEC strength.
