Data Sheet

Cisco RF Gateway 1

Product Overview

The Cisco RF Gateway 1 is a standards-based universal edge QAM (U-EQAM) solution for convergence of high-

speed and high-bandwidth data and video distribution at the edge of the cable access network. The Cisco RF

Gateway 1 offers leading edge density, modularity, and flexibility with support for Switched Digital Video (SDV),

VoD, Broadcast Video, and DOCSIS®3.0/Modular CMTS (M-CMTS)™all on a single QAM platform.

The Cisco RF Gateway 1 provides higher density (up to 96 QAMs per RU), improved reliability, superior RF

performance, 1 GHz RF output, and DOCSIS 3.0/M-CMTS capability. It is fully integrated and tested as part of the

Cisco Digital Broadband Delivery System (DBDS) and the Cisco uBR10012 M-CMTS solution, accelerating the

deployment and easing the management of digital video and DOCSIS services. The Cisco RF Gateway 1 enables

the converged next-generation cable access network by offering comprehensive video and DOCSIS functions in a

single U-EQAM platform.

Features and Benefits

Primary Benefits

The compact Cisco RF Gateway 1 provides the following benefits for cable operators:

●Rapid time-to-market of QAM-based services to generate incremental revenue through a modular, flexible

design based on a proven, fourth-generation QAM architecture

●Efficient use of capital expenditures through maximum spectrum efficiency (SDV, QAM Sharing, 1 GHz)

and U-EQAM functionality (video and data) for flexibility and optimization in a variety of video and data

network architectures

●Quality and reliability through a redundant architecture; full testing and integration with the Cisco DBDS

Video Delivery System and the Cisco uBR10012 M-CMTS Architecture

Primary Features

The Cisco RF Gateway 1 provides up to 96 U-EQAM channels (for SDV, Broadcast, VoD, and DOCSIS 3.0/M-

CMTS) in a compact 1 RU chassis. The modular design supports 16 QAM channels per module, with eight QAM

channels per RF output port and frequency agility up to 1 GHz.

Primary features include:

●True U-EQAM video (broadcast, SDV, SD/HD, MPEG-2, AVC) and high speed data

●(M-CMTS/DTI, DOCSIS 3.0) in 1 RU form factor

●Manual or DEPI Control Plane modes supported

●Table-based or session-based video functionality

●Optional on-board Encryption: DVB®SimulCrypt and PowerKEY®SKS

●Utilizes Direct Digital Synthesis (DDS) QAM technology which allows superior RF performance and stability

●96 configurable QAM channels; each of which is fully agile 45–1000 MHz

●RF performance typically meets or exceeds CableLabs® DRFI specification CM-SP-DRFI

●Modular, hot-swappable, and Auto-configurable QAM cards

●Support for up to 2048 streams in 1 RU

●Fully redundant design with redundant Gigabit Ethernet ports and power supplies (AC/AC, AC/DC, or

DC/DC)

●Front-to-back airflow to allow self-cooling and stacking

●Compliance with ITU-T J.83 standard, Annex A (DVB), Annex B (ATSC), or Annex C (Japan)

●Internet Group Management Protocol Version 3 (IGMPv3) support

●Low power consumption per QAM

●Four or eight QAM channels per RF port available - independent of channel bandwidth (6, 7, and 8 MHz)

●Fully SNMP compliant
