The Cisco uBR-MC88V is capable of eight downstream (Annex A or Annex B) and eight upstream channels. The port count remains exactly the same as the Cisco uBR-MC28U, with two downstream ports and eight upstream ports. This enables the Cisco uBR-MC88V to offer a simple upgrade path from the older line card used on the Cisco uBR7200VXR platform without any change to the cable wiring.The Cisco uBR-MC88V supports eight DOCSIS 3.0 downstream channels through two quad-stacked physical connectors and eight upstream channels each on a unique physical connector. It significantly expands the capacity of the Cisco uBR7200 series universal broadband router to address growing subscriber bandwidth demands and enable cost-effective scalability of services.The line card is compliant with DOCSIS Downstream RF Interface (DRFI) specifications and is designed with an extended frequency range up to 1 GHz by using a highly integrated and low-power-consumption upconverter. With the advanced spectrum management, ingress cancellation, and S-CDMA, the Cisco uBR-MC88V will mitigate ingress noises in the hybrid fiber/coaxial (HFC) plant to achieve better RF performance.
