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

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

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)

CCAP Benefits (cont’d)


page 8

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

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 Slide9

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.

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.
