  • Page 4 Note: Cisco recommends that a dedicated (new) CATV cable drop be run from the grounding block directly to the Cisco uBR924 cable access router. If such a drop is not available, careful qualification of existing cable is often necessary. Cable ground should be connected to the grounding system of the building or residence as close to the point of cable entry as practical.

    Cisco uBR924 is configured to operate in a DOCSIS-compliant bridging mode. Power cycling the Cisco uBR924 ensures the laptop computer does not remain in the list of CPE devices at the subscriber site for the Cisco uBR924 to support. Only reinitialization of the cable interface clears out the bridge table and resets the counter that specifies the number of CPE devices being bridged.
