  5. CCAP Goals • Operational improvements • Environmental efficiencies (e.g. reduced space, power consumption, and heat dissipation) • Increased DS and US density • Flexible use of QAM channels for various services through a single configuration point • DOCSIS-based services (e.g. High Speed Internet, voice, IPTV) • MPEG transport stream-based services (e.g. for VOD, SDV) • Linear Broadcast service • Individually configurable assignment of QAM channels to various service groups • DOCSIS SGs, VOD SGs, and SDV SGs overlap in different ways without requiring that these SGs be identical • Efficient implementation of separate sets of QAM channels for narrowcast and broadcast applications • QAM channels for narrowcast services can be individually implemented for each RF port • QAM channels for broadcast services can be shared among the RF ports in each downstream card • Simplification of the RF combiner network • Providing QAM channels for all digital services from a single RF port • Transport-agnostic network architecture allowing implementation of EPON • CCAP will be expected to support EPON in the future with pluggable components SCTE Rocky Mountain Chapter August 2016

  6. CCAP – Platform Implementation • CCAP can be implemented as a single Integrated CCAP chassis or implemented in a modular fashion • Modular CCAP • Consists of more than one device • A single Packet Shelf – contains the packet processing functions, such as subscriber management, service flow management, layer-3 routing and higher level protocol manipulation • One or more Access Shelves - contains the upstream and downstream PHY functions normally associated with the CMTS and the edge QAM, and nearly all of the DOCSIS MAC • Integrated CCAP • Support all the CCAP requirements in one device • Easier to manage • No interoperability issues with multiple devices SCTE Rocky Mountain Chapter August 2016

  7. CCAP Benefits • Bandwidth Capacity and Density Gains • CCAP is designed to greatly increase the capacity of the device, delivering all narrowcast and broadcast services via the downstream RF ports deployed • Casa DS 8x96 module supports 256 narrowcast channels and 64 broadcast channels • Customers can benefit for the high density DS modules even if they don’t have edge QAM applications • Rack Space and Power Reduction • CCAP has strict requirements on power consumption and rack space • High density results in fewer equipment • CCAP provides support of DOCSIS and Edge QAM applications. As a result, fewer equipment will be required in the Headend • Service Multiplexing Flexibilities • QAM channels for narrowcast services are individually implemented for each RF port • QAM channels for broadcast services are shared among all the RF ports in each downstream card • The number of narrowcast and broadcast QAMs supported on each RF port is flexible • Same narrowcast video QAM can be mapped to multiple downstream ports, allowing for overlap of SDV and VOD service groups • Allow configuration of any QAM in a given CCAP RF port for DOCSIS or Edge QAM applications -> Provide the ability to transition from legacy Edge QAM applications to next generation video services (e.g. IPTV via DOCSIS) SCTE Rocky Mountain Chapter August 2016

  8. CCAP Benefits (cont’d) • Configuration and Management Simplifications • The CCAP will allow configuration of both CMTS and Edge QAM functions from the same configuration interface • CCAP will move away from SNMP-based configuration and focus on the processing of XML configuration files • Local storage and versioning of configuration files aids rapid recovery of services when a primary component has failed • RF Combining Simplifications • Provide all QAM channels for all digital services from a single RF port (only leaving certain legacy functions for RF combining) • Rather than having to rewire the physical plant to make service group changes, the QAM content of a downstream RF port can be changed via the CCAP configuration interface • IP Router Integration • CCAP specification requires to support a wide range of IP applications • Easy migration path from legacy MPEG-TS to IPTV over DOCSIS SCTE Rocky Mountain Chapter August 2016

  9. CASE Study Business/Technical Goals • Channel bound – 8ch DS maximum capacity • Goal was to offer 300MB service 16ch DS • Space limited – need much denser solution to meet current and future requirements • Power – reduce power consumption by 20-30% • Speed – need to replace 400+ legacy CMTS with CCAP within eight months SCTE Rocky Mountain Chapter August 2016

  10. CCAP Environmental efficiencies Actual Deployments vs CCAP 160 HSI service groups, and 120 VOD and matching SDV service groups. Considering typical CMTS and Edge QAM equipment available today, this service group configuration would require about 10 CMTS chassis and about 4 racks for VOD and SDV, each containing 6 Edge QAM chassis configured for 64 QAM channels, each at a density of 4 QAM channels per RF port. The digital broadcast lineup is composed of 60 individual QAM channels, plus the corresponding out-of-band equipment. SCTE Rocky Mountain Chapter August 2016

  17. Session Based Overview • Each new VOD or SDV session generates a CREATE from the SRM. • When session ends SRM sends a DELETE to remove session. • VOD is unicast and SDV is multicast • Protocol has 2-way handshake for all messages. • Supports Video on a per session basis. • All topology information and changes must be manually exported to the SRM. This was done to simplify protocol exchange with the SRM. SCTE Rocky Mountain Chapter August 2016

  25. Background - NYC • In 2014, TWC began a multi-year plan to consolidate its CMTS and Edge QAM architecture to provide higher speeds to the customer • Converged Cable Access Platform HSD High Speed Data CCAP CMTS VOD Video on Demand SDV Switched Digital Video • * In 2013, the Manhattan system was converted from Big Band to NSG for space saving reasons. For this study, we will measure from the NSG on. • Note: Linear broadcast is not currently planned to migrate to CCAP SCTE Rocky Mountain Chapter August 2016

  26. Power and Productivity Scenarios & Financial Benefits Legacy CMTS will consume an additional 597KW for all 25 sites • CCAP will consume an average 30% less power while enabling almost double (93%) the productivity (higher bandwidth) across all 25 sites CCAP will save 313KW for all 25 sites SCTE Rocky Mountain Chapter August 2016
