Note: The Cisco uBR7225VXR E-28U and E-16U BPEs (part numbers UBR-E-28U and UBR-E-
16U) are compatible with the uBR7225VXR chassis only and are not compatible with the
uBR7246VXR. This compatibility function is enabled through both mechanical keying methodology
and software locks to prevent insertion of these cards into any other chassis.
Standards Compliance
The product is compatible with DOCSIS
®
1.1 and 1.0, Euro-DOCSIS 2.0, 1.1, and 1.0, and
PacketCable™ 1.1 standards. It addition, it supports PacketCable Multimedia (PCMM), enabling
cable operators to deploy unique, next-generation multimedia services.
The uBR7225VXR further supports the CableLabs OpenCable DOCSIS Set-Top Gateway (DSG)
specification. DSG enables cable operators to transport upstream and downstream video traffic
directly through the CMTS instead of through a proprietary, standalone video infrastructure.
Incorporating out-of-band messaging in DOCSIS digitally modulated carriers, cable operators can
consolidate cable modem and set-top box data traffic on a shared DOCSIS channel.
As operators evolve their traditional infrastructures to an IP Next-Generation Network supporting IP
data, voice, and video traffic, the CMTS must support advanced routing protocols and offer
advanced automated intelligence. The Cisco uBR7225VXR evolves the CMTS into an intelligent
broadband edge platform that delivers highly competitive service bundles. The product enables
cable operators to capture the full potential of their cable spectrum and DOCSIS hybrid fiber-
coaxial (HFC) networks. The product supports up to 5000 subscribers.
Features and Benefits

●
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.
Primary Benefits
The Cisco uBR7225VXR addresses the expanding service and operational needs of cable
operators, providing the following benefits:
●
Low-cost entry-level CMTS makes efficient use of capital expenditures while maintaining
modularity for capacity growth
●
Provides up to 16 upstream and 4 downstream ports in a 2-RU 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
