Cisco cBR-8 Converged Cable Access Platform (CCAP), DOCSIS 1.x-3.0

Cable/DOCSIS/CMTS/CCAP, Technology

This Cisco cBR-8 CCAP (Converged Cable Access Platform), 4-day Instructor Led Bootcamp provides an architectural understanding and hands-on configuration expertise. An understanding of DOCSIS 1.x through to 3.0 concepts and operation is assumed pre-requisite knowledge. The course focuses on load balancing, HA redundancy, security, and IPv6 features that are available on the cBR-8 CMTS platform. The course includes lab activities and demonstrations to reinforce the key learning objectives.


cBR-8 is the next generation in Cisco’s series of CMTS (Cable Modem Termination System) platforms. Cisco’s uBR 10K (Universal Broadband Router) previously offered industry-leading CMTS functionality – the cBR-8 is now Cisco’s flagship CMTS offering.

The Cisco cBR-8 CCAP (Converged Cable Access Platform) CMTS provides many technology advancements and performance enhancements, while reducing the overall cost per subscriber. These advanced capabilities include: four times the capacity (number of cable modems/subscribers per CMTS) at double the speed of currently available DOCSIS 3.0 solutions on the uBR 10K CMTS. The cBR-8 provides maximum flexibility for the future adoption of innovative network architectures including Remote PHY (RPHY), SDN, and Virtual CMTS (vCMTS). The cBR-8 allows cable operators to deliver ultra-broadband services with maximum downstream speeds approaching 10 Gbps per subscriber and 1 Gbps upstream.

Note: Cisco 10K supports all versions up to DOCSIS 3.0. cBR-8 supports up to 3.1.
