Cisco uMG9850 QAM Module
The Cisco® uMG9850 QAM Module provides the most versatile solution for Gigabit Ethernet-based digital video networks integrating switching, optics, and quadrature-amplitude-modulation (QAM) functions on one platform—the Cisco Catalyst® 4500 Series Switch—to simplify network architectures delivering video-on-demand (VoD) services. Performing as the IP-to-MPEG-2 gateway between the Gigabit Ethernet transport network and the hybrid fiber-coaxial (HFC) cable network, the Cisco uMG9850 QAM Module provides high-performance operation for QAM modulation and upconversion of digital video. The Cisco uMG9850 QAM Module consists of 12 RF ports generating two QAM channels per port for a total of 24 QAMs per module.
Optimized for Gigabit Ethernet Networking
The Cisco uMG9850 QAM Module is optimized for Gigabit Ethernet technology, accepting full line-rate Gigabit Ethernet video transport feeds to provide optimum efficiency. There is no longer a need to daisy-chain QAM devices, eliminating the single point of failure present in the first QAM device in the chain. Configuring multiple Cisco uMG9850 QAM modules into a single chassis provides the ability to switch any video stream from an outgoing Gigabit Ethernet video server port to any QAM channel, fully utilizing the capabilities of Gigabit Ethernet networking. The Cisco uMG9850 QAM Module also lowers distribution hub capital expenditures (CapEx) and reduces the number of devices to be managed.

Flexible Modular Design
The modularity of the Cisco Catalyst 4506 and 4507R Switches accommodates up to five Cisco uMG9850 QAM modules, offering a maximum of 120 QAM channels. This modular solution enhances the scalability by making it easy to add more QAM channels as VoD service grows through the building-block design of the platform. Customers can now purchase spare QAM modules only, rather than an entire fixed-configuration system, lowering the total cost of ownership for in-service video QAM equipment. The Cisco uMG9850 QAM Module also can be mixed with other Cisco Catalyst 4500 Series line cards, further adding to the flexibility of the solution.
The platform supports hot-swappable QAM modules on active systems in operation by taking advantage of the high-availability features built for the system. This accommodates future growth and maintenance, while minimizing costly service outages and maximizing uptime. The platform also offers redundant power supplies, cooling fans, and central processing engines.
Integrating switching, optics, and QAM intelligence into a modular chassis simplifies network design and reduces operational costs. Customers can achieve greater investment protection through the flexibility of the product to evolve as service and capacity requirements increase. The Cisco uMG9850 QAM Module reduces the number of devices needed and provides better manageability than multiple standalone QAMs.
As Cisco Systems® continues to develop intelligent video edge solutions for current and future video services, the Cisco uMG9850 and the Cisco Catalyst 4500 Series provides the foundation for the next-generation digital video network.
