Chapter 1 Cisco uBR10012 Universal Broadband Router Overview
Cable Interface Line Cards
Upstream data from the subscriber, comes through the upstream ports (US0- US19) on the
Cisco
uBR10-MC5X20S/U 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.
Downstream data to the subscriber, comes from the Internet through the WAN/backhaul card, and across
the backplane to the Cisco uBR10-MC5X20S/U cable interface line card.
The Cisco uBR10-MC5X20S/U 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. Each downstream port includes an inboard integrated upconverter.
The Cisco uBR10-MC5X20S/U cable interface line card supports all DOCSIS 1.1-specified Annex B
radio frequency (RF) data rates, channel widths, and modulation schemes and has DOCSIS MAC
management and spectrum management capabilities.
Figure 1-23 shows the faceplate of the Cisco uBR10-MC5X20S/U cable interface line card with the
dense connector configuration.
