Product Overview
The Cisco
®
RF Gateway Downstream 384 (RFGW-DS384) line card is an 8-port, 384-channel universal edge
quadrature amplitude modulation (U-EQAM) modulator designed for operation in the Cisco RF Gateway 10
platform. The Cisco RF Gateway Downstream 384 Universal Edge QAM Line Card provides dramatically increased
density and functionality as compared to the Cisco RF Gateway DS48-1G Universal Edge QAM Line Card.
The Cisco RFGW-DS384 offers concurrent support for standard and high-definition digital broadcast television,
switched digital video (SDV), video-on-demand (VoD), and DOCSIS
®
modular cable modem termination system
(M-CMTS) services. Cable operators can choose to configure the line card as DOCSIS only, video only, or
DOCSIS and video shared universal edge QAM.
In the 10-slot Cisco RF Gateway 10 platform, the Cisco RFGW-DS384 line cards (Figure 1) can be configured with
1:N redundancy (up to 1:9), or 2:N redundancy (up to 2:8), resulting in a fully protected, high-capacity, and highly
dense edge QAM solution. For video services, the line cards can accept multiple formats of video content and
perform a wide array of video processing features. Leading-edge RF technology is used to perform QAM
modulation and RF up-conversion at significant space and power savings compared to previous up-conversion
architectures.
