The Cisco® 5x20H Broadband Processing Engine (BPE) for the Cisco uBR10012 Universal Broadband Router combines industry-leading port density, an advanced RF feature set, next-generation advanced time division multiple access (A-TDMA) capabilities, and DOCSIS® and European DOCSIS (Euro-DOCSIS) support-on a single line card (Figure 1). The Cisco 5x20H BPE is a performance-enhanced update of the Cisco 5x20U Broadband Processing Engine with incremental memory and processor capacity. The line card also supports an extended DOCSIS upstream frequency range of 5 to 55 MHz and downstream support of 70 to 860 MHz for DOCSIS operations in Japan.

The Cisco 5x20H BPE (Figure 1) addresses the expanding service and operational needs of cable operators. A set of advanced features and a scalable architecture make the Cisco 5x20H BPE 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 Cisco 5x20H BPE works with the Cisco 1-Gbps Wideband Shared Port Adapter (SPA) for the Cisco uBR10012 and Cisco SPA Interface Processor for the 1-Gbps Wideband Shared Port Adapter.

Product Overview

The Cisco 5x20H BPE is a cable interface line card for the Cisco uBR10012 that performs cable modem termination system (CMTS) functions, such as:

• Physical layer (PHY) RF interface (upstream burst demodulation, downstream modulation, RF upconversion)

• MAC processing (modem registration, transmission opportunity scheduling, Layer 2 quality of service [QoS])

• Onboard packet processing

Featuring a highly integrated and robust RF front end and an advanced processing engine for DOCSIS-based and Euro-DOCSIS-based networks, the Cisco 5x20H BPE enables high-performance, reliable, and secure bidirectional transmission of IP packets over the cable plant for data, voice, and video services. The card supports:

• DOCSIS: 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 and ITU J.83 Annex B. The card supports downstream channels in the 88 to 860 MHz range, and upstream channels in the 5 to 42 MHz range.

• Euro-DOCSIS: 8 MHz Phase Alternating Line (PAL) and Systemme Electronique Couleur Avec Memoire (SECAM) channel plans conforming to the 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.

• DOCSIS with extensions for Japan: 6 MHz Annex B extension support with a downstream extended frequency range of 70 to 860 MHz and an upstream extended frequency range of 5 to 55 MHz.

Advanced RF Front End

The Cisco 5x20H BPE presents an advanced RF front-end design, combining a very high level of integration with enhanced RF robustness and performance. The innovative design, which uses leading PHY chips from multiple vendors, features five downstream modulators, five upconverters, and 20 upstream burst receivers on a single line card. It embeds advanced RF capabilities, such as direct sampling of the upstream channels and ingress noise cancelation and advanced equalization.

Superior MAC

The Cisco 5x20H BPE features dedicated MAC layer hardware for superior performance in large-scale deployments. The Cisco 5x20H BPE 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). It also provides hardware acceleration for functions such as concatenation, fragmentation, and payload header suppression (PHS) necessary to deploy advanced data and voice services.
