Cisco uBR MC28C Cable Modem (UBR-MC28C)

The Cisco uBR-MC28C cable modem card resides in a Cisco uBR7200 series universal broadband router and supports downstream and upstream traffic to and from Data-Over-Cable Service Interface Specification (DOCSIS)-based cable modems (CMs). The card supports 6-MHz National Television Systems Committee (NTSC) channel operation, using standard (STD), Harmonic Related Carrier (HRC), or Incremental Related Carrier (IRC) frequency plans conforming to EIA-S542. The card supports downstream channels in the 54-to-860 MHz range, therefore, with upstream ranges of 5 to 42 MHz.??The Cisco uBR-MC28C cable modem card: Expands the capacity of a Cisco uBR7200 series universal broadband router, providing the highest port density in Cisco cable modem cards available today, the card offers another downstream channel and additional upstream channels; Gives cable operators additional flexibility in partitioning the cable plant to address growing subscriber bandwidth demands; enables cost-effective scalab...
