The Cisco uMG9850 QAM Module is a switching module for Cisco Catalyst 4500 series switches that allows cable operators to deliver Video-on-Demand (VoD) services to their subscribers. The module receives multiple single-program transport stream (SPTS) MPEG-2 digital video streams over IP. Modulated and upconverted RF signals are then delivered to subscribers' digital set-top boxes.
The Cisco uMG9850 QAM Module provides 12 downstream dual-QAM RF ports, through three groups of four F-connectors. Other ports on the module include a 10/100/1000 Gigabit Ethernet (GE) port, an SFP-GE port, and an ASI monitor port.
