ITEM DESCRIPTION
The Cisco uBR10-MC5X20S, U and H cable interface line cards are 20 by 16 inch cards designed specifically for the Cisco uBR10012 router. These cards transmit and receive RF signals between the subscriber and the headend over hybrid fiber-coaxial (HFC) system.
Upstream data, from the subscriber, comes through the upstream ports (US0-US19) on the Cisco uBR10-MC5X20S/U/H cable interface line card. The line card processes and configures the data and sends it across the backplane to the WAN/backhaul card and out to the Internet.ITEM DESCRIPTIONThe Cisco uBR10-MC5X20S, U and H cable interface line cards are 20 by 16 inch cards designed specifically for the Cisco uBR10012 router.

Downstream data, to the subscriber, comes from the Internet through the WAN/backhaul card, and across the backplane to the Cisco uBR10-MC5X20S/U/H cable interface line card. The Cisco uBR10-MC5X20S/U/H card processes and configures the data and sends it out through the appropriate downstream port (DS0-DS4) to be combined with the rest of the downstream signals in the headend.
