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 nextgeneration

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

● 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
