The Cisco uBR-MC20X20V, Figure 1, delivers support for DOCSIS and EuroDOCSIS 3.0, including full upstream and downstream channel bonding and Advanced Encryption Standard (AES) encryption. The line card provides the capability to have 160 downstream and 160 upstream interfaces in a single Cisco uBR10012 chassis and, when used with the DOCSIS 3.0-capable Cisco 1 Gbps Wideband Shared Port Adapter (SPA), can scale to 304 downstream channels. [ note: DOCSIS is another company's trademark, and not part of the SPA's product name] This leads the industry in capacity. The Cisco uBR-MC20X20V is operationally exceedingly simple to upgrade from the Cisco 5x20H BPE or Cisco 5x20U BPE. Further, Cisco offers pay-as-you-grow flexibility with software licensing for downstream channels (0DS, 5DS and 20DS SW licenses are offered).
Although the uBR-MC20X20V BPE offers 20 downstream (Annex A or Annex B) and 20 upstream channels, the physical port count remains exactly the same as the Cisco 5x20H, with 5 downstream ports and 20 upstream ports. Each downstream port is capable of carrying four frequency-stacked downstream channels. Each downstream channel is configurable as part of a DOCSIS 3.0 channel bonding group or DOCSIS 2.0/1.x channel (primary capable). The line card also supports an extended DOCSIS upstream frequency range of 5 to 65 MHz and downstream of 55 MHz to 1 GHz for DOCSIS operations. Each upstream channel can be configured into a DOCSIS 3.0 upstream channel bonding group while serving DOCSIS 2.0/1.x cable modems/devices at the same time.
The Cisco uBR-MC20X20V delivers cutting-edge features and a highly scalable architecture to enable cable operators to deliver carrier-class, IP-based, high-bandwidth, high-speed data, voice, and video services to subscribers.
