Product Overview
The Cisco
®
RF Gateway Downstream 48-1G Universal Edge QAM Line Card is a 12-port, 48-channel universal
edge quadrature amplitude modulation (UEQAM) modulator designed for operation in the Cisco RF Gateway 10
platform. This line card is very similar in function to the standalone Cisco RF Gateway 1 Universal Edge QAM
product, but the Cisco RF Gateway 10 can accommodate up 10x the density of the Cisco RF Gateway 1.
The Cisco RF Gateway Downstream 48-1G UEQAM line card 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 a
DOCSIS only, video only, or DOCSIS and video shared universal edge QAM.
In the 10-slot Cisco RF Gateway 10 platform, RF Gateway Downstream 48-1G UEQAM line cards (Figure 1) can
be configured with 1:N redundancy (up to 1:9), 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 provide a wide
range of video processing features. Leading-edge RF technology is used to perform QAM modulation and
RF upconversion, at significant space and power savings compared to existing upconverter architectures.
