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.
• Designed to support CableLabs-defined universal edge QAM specification for multiple vendor interoperability
• Concurrent support for Annex A, B, and C operations on the same line card
• Can support mixed annex environments on the same line card with granularity per port (for example, Annex B for DOCSIS, Annex A for video)
• 384 QAM channels per line card, 640 replicated QAMs per line card, up to 128 QAMs per port, up to 10 line cards per Cisco RF Gateway 10 chassis (up to 3840 QAMs per chassis)
• High capacity edge QAM solution reduces the total number of devices to manage and provides
• Non-adjacent frequency support
• Allows flexibility on assigning output frequencies
• Optional integrated Cisco PowerKEY® and Digital Video Broadcasting (DVB) encryption
• Minimizes cost and complexity of deploying encrypted services
• Flexible licensing of QAM capacity and encryption
• Supports pay-as-you-grow
High Availability
• Supports high availability for universal edge QAM applications
• Industry's first carrier-class edge QAM platform provides continuous service availability and reduces the duration of planned service outages
Operations and Management
• Software based on QNX microkernel-based real-time, high-performance operating system
• As in the Cisco Carrier Routing System 1 (CRS-1) range of products, QNX is the basis of the Cisco RFGW-DS384 software architecture, providing a very stable, scalable, and efficient operating system

A minimum configuration of 64 counts of SWLIC-DS384 is required when purchasing Cisco RFGW-DS384 hardware.
Notes on Licenses
• If purchasing multiple line cards, each line card in the order must have the same number of upstream and downstream licenses. Upgrade licenses may be purchased in case customers need line cards with different licenses.
• eDelivery allows for electronic delivery of purchased license product activation key (PAK).
• Partial fulfillment is supported. If customers wish to purchase upgrade licenses for multiple hardware devices (for example, if they wish to upgrade all their Cisco RFGW-DS384), partial fulfillment allows all upgrade licenses to be generated using a single PAK if the customer desires. This can greatly increase operational ease of license upgrades.
• Return materials authorization (RMA): Cisco Services will replace faulty hardware with hardware that has no downstream or upstream licenses. Customers will need to transfer licenses from the failed board to the new board to make it operational.
