COURSE DESCRIPTION:

Students taking the DOCSIS Network Overview training course will learn about DOCSIS basics and the physical network it runs on.

COURSE OVERVIEW:

Students enrolled in the DOCSIS Network Overview training course will learn about DOCSIS basics, modem operations, and the digital modulation schemes employed by DOCSIS. The Hybrid Fiber/Coax (HFC) network, which DOCSIS runs on in a cabled world, is also explored. The course provides a foothold to a deeper dive into DOCSIS.

COURSE OBJECTIVES:

COURSE DESCRIPTION: 
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.

COURSE OVERVIEW:
Remote PHY (R-PHY) is a key component in the cable industry’s adoption of a Distributed Access Architecture (DAA). DAA and R-PHY are foundational technologies for future innovative network architectures such as Virtual CMTS (vCMTS), Cloud Native Broadband Router (cnBR), and Full-duplex DOCSIS. R-PHY enables the migration of physical layer (PHY) functions (such as RF Spectrum generation) from the Headend to the network edge – leading to more robust RF networks. The deployment of DAA/R-PHY, coupled with DOCSIS 3.1, allows cable operators to deliver ultra-broadband services with maximum downstream/upstream speeds approaching 10 Gbps/1 Gbps respectively.
