Implementing Cisco’s Converged Cable Access Platform (cBR-8)

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 (10K). 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’s native support of DOCSIS 3.1 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.
