1Overview
The Cisco RF Gateway 10 (RFGW-10) is a Carrier Class Universal Edge Quadrature Amplitude Modulation (UEQAM) platform that offers concurrent support for Standard and High Definition Digital Broadcast Television, Switched Digital Video (SDV), Video on Demand (VoD), and DOCSIS/Modular CMTS services.
The Cisco RFGW-10 UEQAM is a chassis based product that is based on open standards with superior performance, capacity, power consumption, ease of management and scalability. All components of the Cisco RFGW-10 UEQAM are designed for high availability including dual Supervisor and Ethernet switching line cards, 1:N Universal Edge QAM line cards, dual Timing and Control line cards, dual load balancing and load sharing DC PEM and integrated RF switching modules.
The Cisco RFGW-10 is targeted to the Cable Operators worldwide, and is optimized for operators requiring carrier class high availability solutions and wanting to collapse video and data over cable EQAM systems into common platform. A collapsed Universal EQAM architecture achieves the following business benefits; EQAM resource utilization gains, cost efficiencies, rack space optimization, reduced cost and complexity of management, and high availability for all services. The Cisco RFGW-10 is part of the Cisco’s Cable ecosystem, and is fully integrated and tested as part of the Cisco Digital Broadband Delivery System (DBDS) video solution and Cisco uBR10012 DOCSIS 3.0 and Modular CMTS solution.
The Cisco RFGW-10 is a centralized switching architecture leveraged from the Cisco® Catalyst® 4500 Series switches. The Cisco RFGW-10 is a 13RU Carrier class, modular chassis designed for providing front to back airflow and system level redundancy. All chassis components are hot-swappable and redundant. The chassis supports “wire-once” cabling for RF line cards and an integrated dual-zone RF switch matrix. The supervisor engine provides non-blocking, robust Layer 2-4 switching with the addition of wire-speed 10-Gigabit Ethernet uplinks, 136Gbps capacity and 102mpps packet throughput.
The Cisco RFGW-10 system is a UEQAM that supports both upstream and downstream RF cards over a frequency range of 5MHz – 1.2GHz. The initial line card release is a UEQAM downstream card that supports the DOCSIS (1.0/2.0/3.0), the EURODOCIS, and J-DOCSIS specifications. Additionally, the card supports High Definition Digital Broadcast Television, Switched Digital Video (SDV), Video on Demand (VoD) video delivery.
Based on the Cisco IOS networking software, the Cisco RFGW-10 supports advanced switching and routing features. The platform supports full upgradeability, ensuring investment protection as software enhancements and industry standards continue to evolve.

Cisco RF Gateway 10 Components
The front-side components include the supervisor cards, RF line cards, and the front panel LCD. The rear-side components include the fan assembly, RF Switch cards (coaxial terminations), Timing, Communication, and Control (TCC) (DOCSIS Timing Interface (DTI) Clock) cards, and the DC PEM modules.
All components (excluding the LCD) are hot-swappable and field replaceable. A fully configured system will operate with a single DC PEM installed; the second PEM is required for power supply redundancy and power load sharing.
Note Proper configuration of the DC PEM requires that both the external power connections, Input 1 and Input 2, are connected to the external power source and the GND connections are connected to the Earth GND. Input 1 and Input 2 on the DC are not redundant power inputs. If only one of the inputs is connected to the external power, the Cisco RFGW-10 UEQAM will not power on correctly.
Figure 1 shows the location of the front-side and the rear-side system components for the Cisco RFGW-10 UEQAM.
