Figure 1. Cisco uBR-MC20X20V Broadband Processing Engine
The Cisco uBR-MC20X20V is an integral part of Cisco’s DOCSIS 3.0-capable Cable Modem Termination System
(CMTS) product portfolio.
The Cisco uBR-MC20X20V BPE addresses the needs of cable operators who expect to cost-effectively deploy very
high-bandwidth services with DOCSIS 3.0. The line card has been designed to offer an operationally simple upgrade
path from the Cisco 5x20H or Cisco 5x20U in terms of both cabling and online insertion and removal (OIR)
compatibility. The Cisco uBR-MC20X20V works with the Cisco RF switch with no cabling changes required from
existing installations using the Cisco 5x20H. The Cisco uBR-MC20X20V further enhances Cisco’s integrated and
modular CMTS offering because it interoperates with the Cisco 1 Gbps Wideband SPA to provide even more
downstream capacity in the same Cisco uBR10012 chassis (up to 304 Downstream channels).
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.
Features and Benefits
Fully DOCSIS 3.0 Capable
Fully DOCSIS and Euro-DOCSIS 3.0 capable, the Cisco uBR-MC20X20V supports downstream and upstream
channel bonding at DOCSIS line rate that enables cable operators to offer very high-speed data services to
residential and commercial subscribers while continuing to offer IP voice services. The line card supports bonding of
four, eight, and even higher number of channels, and other DOCSIS 3.0 features including IPv6, multicast, and S-
CDMA.
Superior Downstream RF Performance
The Cisco uBR-MC20X20V features an upconverter module that is based on industry-leading Direct Digital
Synthesizer (DDS) technology. DDS technology offers superior RF performance in a much smaller footprint than
older analog designs. The upconverter complies with DOCSIS Downstream RF Interface (DRFI) specifications. The
upconverter also operates all the way to 1 GHz.
