The Cisco uBR-MC16X cable interface line card is one of the broadband processing engine (BPE) series of cable interfaces that are available for the Cisco uBR7246VXR universal broadband router. The BPE cards provide increased performance and advanced radio frequency (RF) management, as well as innovative, integrated tools for sophisticated content, traffic, and network management.The Cisco uBR-MC16X card has one downstream port and six upstream ports, organized into a single DOCSIS MAC domain. The downstreams on Cisco uBR-MC16X card do not include integrated upconverters. Instead, the downstream ports generate an IF signal that must be converted through an external upconverter before transmission on the cable network. This allows the Cisco uBR-MC16X card to easily replace existing line card installations that currently use external upconverters.
