cable upstream ingress-noise-cancellation
where interval is the time period in milliseconds specified by the cable upstream ingress-noise-
cancellation command, and channel-symbol-rate is the symbol rate in kilohertz. For example, if the
upstream is using a 2.56 MHz channel rate and a noise cancellation interval of 10 milliseconds, the
bandwidth cost is 1% of the total raw bandwidth:
This command is available only on the Cisco uBR-MC5X20U, Cisco uBR-MC16U/X and
Note
Cisco uBR-MC28U/X cable interface line card. It cannot be used on other cable interface line cards.
Examples The following example shows how to configure the first upstream on a Cisco uBR-MC16U/X or
Cisco uBR-MC28U/X card to perform ingress noise cancellation every 300 milliseconds:
Router# configure terminal
Router(config)# interface cable 5/0
Router(config-if)# cable upstream 0 ingress-noise-cancellation 300
Router(config-if)#
