UBR-E-28U compatible with the uBR7225VXR only and are not compatible with the Cisco uBR7246VXR. This compatibility function is enabled through both mechanical keying methodology and software locks to prevent insertion of these cards into any other chassis.

The Cisco uBR7225VXR E-28U Broadband Processing Engines (BPEs), part numbers UBR-E-28U bring new choices and capabilities to the Cisco uBR7225VXR Universal Broadband Router. Advanced features and a scalable architecture make these line cards the right choice for cable operators delivering carrier-class IP-based data, voice, and video services to a growing number of subscribers. These BPEs offer greater flexibility and robustness to the Cisco uBR7225VXR communications-grade CMTS.

Primary Features:

• An advanced physical layer (PHY) to provide ingress noise cancellation
• Advanced time-division multiple access (A-TDMA) capabilities
• Advanced spectrum management
• An onboard processor for improved performance to support additional subscribers and services
• Integrated upconverters for Cisco uBR7200 Series uBR-E-28U and uBR-E-16U (part numbers UBR-E-28U and UBR-E-16U) line cards
• Flexible software Media Access Control (MAC) domain configuration or virtual interfaces
• Reduced cable wiring through frequency stacking
• DOCSIS®, European DOCSIS (Euro-DOCSIS), and J-DOCSIS compliance on one line card
• Integrated upconverters: depending on the specific model, one or two downstream modulators and eight or six upstream burst receivers on a single line card
• Patented Cisco technology determines carrier-to-noise ratio (CNR) values for selected upstream channels
• Meet or exceed DOCSIS specifications of 35 dB for downstream CNR and 25 dB for upstream operation

Primary Benefits:

The Cisco uBR7225VXR E-28U and E-16U BPEs (part numbers UBR-E-28U and UBR-E-16U) address the expanding service and operational needs of cable operators. They provide the following benefits:
• Low-priced entry-level cable line card makes efficient use of capital expenditures, while maintaining modularity for capacity growth
• Provides up to 16 upstream and 4 downstream ports in a 2-rack-unit form factor
• Support of DOCSIS, Euro-DOCSIS 2.0, and PacketCable 1.1 technology helps return on investment for converged services and speeds deployment of advanced IP services
• Provides DOCSIS, Euro-DOCSIS, and J-DOCSIS support on one line card for operational savings and lower capital expenditure
