Product Review

The CISCO UBR7225VXR is designed with a modular architecture, supporting a wide range of cable network standards including DOCSIS 1.1 through 3.0 and Euro-DOCSIS 2.0 and 3.0, which allows for flexibility and scalability in Tier 2 and Tier 3 cable network deployments. However, with only 4 downstream and 16 upstream ports, its capacity may be limiting for larger network demands, despite its compatibility with advanced modulation techniques for efficient data transmission. Additionally, the requirement for a 19-inch rack space for a unit weighing 45 lbs with dimensions of 3.5 in. x 17.32 in. x 21.8 in. necessitates considerable physical space and planning for proper airflow and temperature management within network infrastructure.


The CISCO UBR7225VXR is a modular cable modem termination system designed specifically for tier 2 and tier 3 cable networks. This device is engineered to support a variety of standards including PacketCable 1.1, DOCSIS 1.1, Euro-DOCSIS 2.0, DOCSIS 3.0, Euro-DOCSIS 3.0, and PacketCable Multimedia, ensuring compatibility with a broad range of network protocols and configurations. The UBR7225VXR features a compact design with dimensions of 3.5 inches in height, 17.32 inches in width, and 21.8 inches in depth, and weighs 45 lbs, making it suitable for environments where space is at a premium. Equipped with 16 upstream and 4 downstream ports, this device facilitates efficient data transmission and high-speed connectivity. The downstream frequency range for DOCSIS is 70MHz to 1GHz with a 6 MHz channel width (Annex B), and for Euro-DOCSIS, it's also 70MHz to 1GHz but with an 8 MHz channel width (Annex A). The upstream frequency range supports 5-42 MHz for DOCSIS (Annex B) and 5-65 MHz for Euro-DOCSIS (Annex A), enabling flexible and reliable upstream data transmission. At its core, the UBR7225VXR utilizes a uBR7200-NPE-G2 Processor equipped with at least 1GB of DRAM, providing the necessary processing power to handle complex network tasks efficiently. The device operates optimally within a temperature range of 0 °C to 40 °C, with a non-operating temperature tolerance between -20 °C to 65 °C. Its side-to-side cooling mechanism ensures stable performance by maintaining an airflow of -125 cfm, while the system's design allows it to operate under humidity levels ranging from 10% to 90% (non-condensing). Safety is a priority with the UBR7225VXR, which meets various safety approvals including UL/CSA/IEC/EN 60950-1 and AS/NZS 60950.1. The system requires a minimum of Cisco IOS Software Release 12.2SB and supports features such as IPv6 ACLs, Virtual Interface Bundle, and DMIC, enhancing its functionality and security measures. Additionally, the device includes a fan tray and features ingress noise cancellation to improve operational efficiency and reliability. Mounting the UBR7225VXR is made flexible with front, mid, and rear mounting options, designed to fit a standard 19-inch rack. Its design style is modular, allowing for easy expansion or modifications as network requirements evolve. Key hardware specifications include: - Modulation Techniques: 64-QAM and 256-QAM for downstream; QPSK and 8-, 16-, 32-, 64-QAM for upstream, ensuring adaptable and efficient data transmission. - Rack Size Compatibility: Designed for a 19-inch rack, accommodating two racks for installation. - Comprehensive Standards Support: Compatibility with multiple standards including PacketCable 1.1, DOCSIS versions up to 3.0, and Euro-DOCSIS versions up to 3.0. The CISCO UBR7225VXR stands out as a versatile and efficient solution for cable network operators, providing the necessary features and specifications to support high-speed internet and multimedia services.
