Cisco – uBR-MC28U-R – Refurbished Cisco uBR-MC28U card

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.


Cisco Systems® introduces four new cable line cards—the Cisco uBR7200 Series MC28U, MC28X, MC16U, and MC16X Broadband
Processing Engines (BPEs)—that bring new choices and capabilities to the Cisco uBR7246VXR Universal Broadband Router. With their
flexible, all-inclusive product design, the line cards offer:
· An advanced physical layer (PHY) to provide ingress noise cancellation
· Advanced time-division multiple access (A-TDMA) capabilities
· Advanced spectrum management
· An onboard processor for improved performance to support additional subscribers and services
· Integrated upconverters for Cisco uBR7200 Series MC28U and MC16U line cards
· Flexible software Media Access Control (MAC) domain configuration or virtual interfaces
· Reduced cable wiring through frequency stacking
