The Cisco uBR7225VXR Universal Broadband Router is a 2-rack-unit (RU) modular, inexpensive, mid-level entry CMTS suitable for cable operators that require a higher capacity platform than the Cisco uBR7100 Series, but not the larger form factor or capacity of the Cisco uBR7246VXR or Cisco uBR10012. The Cisco uBR7225VXR is based on open standards and brings the power and reliability of the Cisco uBR7246VXR within reach of all cable operators. See Figure 1.
The Cisco uBR7225VXR delivers a feature-rich CMTS for emerging markets and Tier 2 and Tier 3 cable networks evolving to an IP Next-Generation Network infrastructure that supports the deployment of revenue-generating services. This product offers cable operators, multiunit businesses, and ISPs a superior and cost-effective platform for the delivery of high-speed data, voice, and video services. This new CMTS platform requires exceptionally low capital investment and minimal setup time, and it supports up to 5000 subscribers.
The uBR7225VXR Universal Broadband Router is a service-enabling, communications-grade CMTS that offers carrier-class reliability, modular scalability, and significant investment protection. Because of its support for a broad range of features, cable operators can cost-effectively deploy solutions that address a wide range of density, performance, and service requirements with confidence that the router also will support future networking needs. In addition, unlike a fixed configuration CMTS such as the Cisco uBR7100 Series, the modularity of the processor and line card slots in this platform allows for future upgrades in capacity as technology evolves.
The Cisco uBR7225VXR offers feature-rich software. Cisco IOS® Software provides end-to-end Internet connectivity and includes options to help ensure highly secure communications over the cable and IP network.
Cable Line Cards
Two new cable line cards-the Cisco uBR7225VXR E-28U and E-16U Broadband Processing Engines (BPEs), part numbers UBR-E-28U and UBR-E-16U-bring new choices and capabilities to the Cisco uBR7225VXR. Advanced features and a scalable architecture make the Cisco uBR7225VXR and these BPEs the right choice for cable operators delivering carrier-class IP-based data, voice, and video services to a growing number of subscribers. Should you choose to, you may reuse Cisco uBR7200 Series MC16U and MC28U BPEs in the Cisco uBR7225VXR chassis.
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.

Multicast enhancements
DOCSIS 3.0 Multicast QoS addresses various limitations in the current Multicast QoS implementation (for instance, QoS can now be applied to sub-interfaces and VPNs), allowing a single QoS template to be applied to multiple multicast streams
Intelligent Multicast Admission Control (AC):
• Integrates Multicast QoS with Unicast QoS under unified control model, simplifying operation
• Multicast service flows are deleted once all multicast streams stop and all members go away, helping operators reclaim bandwidth
Option to disable IP Multicast echo per cable bundle allows operators to hide subscriber-generated multicast traffic from other subscribers on the same cable subnet
Multicast in MPLS VPN / L3 VPN (mVPN) service (with BPI+)
IP multicast support for MPLS/L3 VPN VRF
Ability to track and isolate streams and membership within a VPN by encrypting the multicast stream with unique BPI SAIDs and keys across VPNs
CMTS Service Independent Intercept (SII)
• Transparency for data intercept (unlike cable-intercept)
• Common architecture for voice and data
• Controlled by Mediation Device, not call control equipment
• Separates lawful intercept control from call control
• Open interface for Mediation Device and Call Control partners
• Documented in IETF Informational RFCs
