Cisco Universal Broadband Router Line Cards

Cisco uBR Line Cards - DOCSIS 1.1 Qualified Interfaces


Cisco Universal Broadband Router Line Cards—A Full Set of DOCSIS 1.1—Qualified Interfaces


Cisco Systems® offers a full set of Universal Broadband Router line cards to partition a Data Over Cable Service Interface Specifications (DOCSIS) cable network and improve system effectiveness (Figure 1). The line cards offer cost-effective market entry and network scaling alternatives to configure upstream-to-downstream channel ratios. They support an unprecedented array of capabilities that enable delivery of differentiated services-with guaranteed service levels-to large numbers of subscribers. The line cards meet all DOCSIS Annex B RF data rates, channel widths, and modulation schemes.

Applications

  • Intelligent routing of IP data and voice between the cable headend and cable modems or cable telephony devices
  • Flexible partitioning of the network

Product Description

Table 1 on the next page lists the DOCSIS Universal Broadband Router line cards that support bidirectional and telephone-return operations. The line cards are supported on both the Cisco® uBR7200 Series and uBR10012 Universal Broadband Router. When housed in a Cisco uBR10012, a line card adapter must be used with the Cisco Universal Broadband Router line card.

Cisco also offers the MC16E Universal Broadband Router line card to support European DOCSIS (EuroDOCSIS) operations. Cisco offers other line cards that support DOCSIS operations. These include the Cisco 5x20U and 5x20 Broadband Processing Engine supported on the Cisco uBR10012, and the Cisco uBR7200 Series MC28U, MC16U, MC28X, and MC16X Broadband Processing Engine supported on the Cisco uBR7246VXR. For these products, see their respective data sheets.
