The Cisco DOCSIS 3.0 Channel Bonded Cable Modem is designed to meet the CableLabs Data Over Cable Service Interface Specifications (DOCSIS) 3.0 specifications, which feature support of four bonded downstream channels and four bonded upstream channels. It is designed to be backward-compatible for use as a single-channel cable modem with DOCSIS and Euro-DOCSIS 1.1/1.0 and 2.0 networks. This comprehensive approach to interoperability makes the Cisco DOCSIS 3.0 Channel Bonded Cable Modem an excellent choice to support high-speed service, providing the potential for a migration path to even more advanced services for consumers.
The Cisco downstream channel-bonding solution features the Cisco uBR10012 cable modem termination systems (CMTS), Cisco xDQA-24 edge quadrature amplitude modulators (QAMs), and Cisco DOCSIS 3.0-compliant cable modems. Cisco was recently awarded bronze qualification by CableLabs reg; for its CMTS headend gear. The announcement comes at the conclusion of the recent test wave in which the first products based on the DOCSIS 3.0 specifications were formally evaluated.
The Cisco uBR-MC5X20S/U/H and Cisco uBR10-MC5X20U-D cable interface line cards can be used for a standard DOCSIS 1.x and DOCSIS 2.0, or for a Cisco DOCSIS 3.0 Downstream Solution or for a combination of the two. These cable interface line cards support upstream and downstream traffic over DOCSIS-based cable modem networks.
The Cisco uBR10-MC5X20S cable interface line card supports downstream and upstream traffic over DOCSIS-based cable modem networks. The line card supports downstream channels in the 70 MHz to 860 MHz range, and upstream channels in the 5 MHz to 42 MHz range. Each downstream port includes an onboard integrated upconverter. The Cisco uBR10-MC5X20S cable interface line card supports Annex B RF data rates, channel widths, and modulation schemes and has DOCSIS MAC management and spectrum management capabilities. DOCSIS 2.0 and Asynchronous Time Division Multiple Access (A-TDMA) rates are also supported.
