Cisco UBR10-MC5X20H-D-RF

The Cisco uBR10-MC5X20H line cards use burst receivers that report equalized MER. Equalized MER will almost always be at least a few decibels (dB) higher than an unequalized MER measurement of the same signal under identical conditions. This is normal. Many of customers see a 2 to 4 dB difference between the equalized MER reported by the MC5X20H, and the unequalized MER reported by the MC5X20S/U on the same upstream. But, if significant channel response impairments are present, the difference between equalized and unequalized MER can be substantially greater.The Cisco uBR10-MC5X20H cable interface line card supports both DOCSIS and EuroDOCSIS cable modem networks. The card supports downstream channels in the 70 to 860 MHz range, and upstream channels in the 5 to 65 MHz range. Each downstream port includes an onboard integrated upconverter. The Cisco uBR10-MC5X20H cable interface line card supports Annex B and Annex A radio frequency (RF) data rates, channel widths, and modulation schemes and has DOCSIS MAC management and spectrum management capabilities. DOCSIS 2.0, A-TDMA rates are also supported.
