The Cisco uBR7200 Series MC28U, MC28X, MC16U, and MC16X BPEs deliver advanced CMTS functions, such as:
· PHY RF interface (upstream burst demodulation, downstream modulation, RF allocation)
· MAC processing (modem registration, transmission opportunity scheduling, and hardware-accelerated Layer 2 QoS)
· On-board packet processing
Featuring a highly integrated and robust RF front end and superior processing engine for DOCSIS- or Euro-DOCSIS-based networks, the
Cisco uBR7200 Series MC28U, MC28X, MC16U, and MC16X BPEs enable high-performance, reliable, and secure bidirectional
transmission of IP packets over the cable plant for data, voice, and video services. The cards support:
· 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, Annex B. The card supports downstream channels in the
88 to 860 MHz range, and upstream channels in the 5 to 42 MHz range.
· 8 MHz Phase Alternating Line (PAL) and Systemme Electronique Couleur Avec Memoire (SECAM) channel plans conforming to the
International Telecommunications Union (ITU) J.83 Annex A standard. The card supports a greater upstream spectrum range of 5 to 65
MHz and an increased downstream channel width of 8 MHz.
· 6 MHz J-DOCSIS channel operation (extensions for Japan and select regions): 6 MHz Annex B extension support with a downstream
extended frequency range of 70 to 860 MHz and an upstream frequency range of 5 to 55 MHz.
