DATA SHEET
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

• Data Over Cable Service Interface Specifications (DOCSIS®), European DOCSIS (Euro-DOCSIS), and J-DOCSIS support on one line card.

The Cisco uBR7200 Series MC28U, MC28X, MC16U, and MC16X line cards address the expanding service and operational needs of multiple system operators (MSOs). An unmatched set of advanced features and a scalable architecture make these line cards an ideal choice for cable operators facing the challenge of delivering carrier-class IP-based data, voice, and video services to a growing number of subscribers. The line cards provide unparalleled flexibility and improved robustness to the Cisco uBR7246VXR, further enhancing this communications-grade cable modem termination system (CMTS). The DOCSIS and Euro-DOCSIS 2.0-qualified and PacketCable 1.1-qualified technology help cable operators accelerate deployment of advanced IP services. By upgrading existing Cisco uBR7246VXR CMTSs with new Cisco BPEs, cable operators can improve overall bandwidth availability and increase their signal quality and reliability. This evolutionary upgrade to existing Cisco CMTSs adds processing power and hardware-accelerated quality of service (QoS) capabilities without requiring a chassis upgrade, and therefore delivers exceptional investment protection. Figure 1 depicts the Cisco uBR7200 Series MC28U BPE.

PRODUCT OVERVIEW

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.

Advanced RF Front End

The Cisco uBR7200 Series MC28U, MC28X, MC16U, and MC16X line cards combine the highest level of integration with enhanced RF robustness and performance for the Cisco uBR7246VXR. The innovative design uses leading PHY chips from multiple vendors. Advanced RF features include direct sampling of the upstream channels and automatic ingress noise cancellation.
The Cisco uBR7200 Series MC28U, MC28X, MC16U, and MC16X use technology patented by Cisco to determine carrier-to-noise ratio (CNR) values for selected upstream channels. This technique, not offered by any other CMTS vendor, is a Cisco differentiator. Cable operators routinely measure CNR as one means of characterizing the health of their cable networks. Understanding CNR, how it degrades through a cascade of devices, and how it affects all the signals carried on the network are critical to ensuring reliable network operation.. Cisco's revolutionary technique offers a higher degree of accuracy and flexibility when calculating this value. Conventional techniques for estimating CNR of selected upstream channels are based upon Error Vector Magnitude (EVM) calculations. Cisco's patented technique achieves precise CNR measurements by scheduling timeslots on selected channels specifically for collecting signal and noise information. The technique supports measurements on a node-by-node basis to analyze CNR on one or more specific modems of an upstream channel-not supported using EVM-based calculations. Cisco uBR7200 Series MC28U, MC28X, MC16U, and MC16X meet or exceed DOCSIS specifications for downstream CNR of 35 dB and 25 dB for upstream operation.
In addition, the Cisco uBR7200 Series MC28U and MC16U feature integrated upconverters. Depending on the specific model, either one or two downstream (DS) modulators and eight or six upstream (US) burst receivers are offered on a single line card.

Superior MAC

The Cisco uBR7200 Series MC28U, MC28X, MC16U, and MC16X line cards feature dedicated MAC layer hardware for maximum performance in large-scale deployments. The MAC layer hardware enables scalability to thousands of cable modems, simultaneously providing hardware acceleration for sophisticated security features, such as DOCSIS 1.1 extensions to baseline privacy interface (BPI+), or processor-intensive functions, such as concatenation, fragmentation, and payload header suppression (PHS) necessary to deploy advanced data and voice services.

Flexible Software MAC Domain Configuration or Virtual Interfaces

Cisco BPEs support flexible upstream allocation and usage-known as software MAC domain configuration or virtual interfaces. Cable operators can associate differing combinations of upstreams to downstreams. Upstreams are no longer fixed by their physical location, but can be assigned to virtual upstream channels. For instance using a Cisco MC28U or MC28X, a cable operator can associate any combination of upstreams (up to eight) to each of the two downstreams. Operators can configure one downstream, six upstreams, plus one downstream and two upstreams, or can configure two independent 1x4 CMTS MAC domains. MAC domains can be configured according to a particular class of service that groups downstreams and upstreams by application; e.g., commercial service requiring a higher QoS or flat-rate residential service. Cable operators can configure MAC domains in a more flexible and dynamic manner to meet differing customer demands and usage. If more capacity is required in one MAC domain, operators can reconfigure the BPE, as opposed to creating a new MAC domain by installing a new cable line card.

Compatible Cisco Network Processing Engines (NPEs)

To operate Cisco uBR7200 Series MC28U, MC28X, MC16U, and MC16X BPEs, the Cisco uBR7246VXR must contain a Cisco NPE-400 or uBR7200-NPE-G1 processor. The NPE-400 must have at least 128 MB of DRAM memory (see recommendation that follows). The uBR7200-NPE-G1 must have at least 256 MB of DRAM memory (see recommendation that follows). If the Cisco uBR7246VXR contains more than one BPE, Cisco recommends installing 256 MB of DRAM memory on the NPE-400, and installing either 512 MB or 1 GB of DRAM memory on the uBR7200-NPE-G1, to ensure best performance.
