Cisco uBR MC88V - Cable modem - refurbished
- High port density
- Superior RF performance
- Rich Cisco technology-specific features
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.

Rich Cisco technology-specific features
The line card supports Cisco technology-specific features such as Dynamic Bandwidth Sharing (DBS), advanced spectrum management, and Subscriber Traffic Management (STM). DBS is the dynamic allocation of bandwidth for wideband and integrated cable interfaces sharing the same downstream channel, which allows each channel to claim the bandwidth unused by others. The DBS feature interacts with DOCSIS 2.0 load balancing to fully utilize bandwidth resources.
