DOCSIS 3.1 GETTING THE MOST OUT OF YOUR HFC

2 October 2014 7


•  Beginning of Data Over Cable System Interface SpecificaWon (DOCSIS) •  Defined support for High-‐speed Data over HFC

THE HISTORY OF DOCSIS

•  Adds state of the art QoS techniques for priority services (e.g. VoIP)

•  Increased upstream modulaWon format for more b/s/Hz •  Added a new PHY for the upstream SCDMA •  Defined a state of the art advanced MAC •  Enabled two (2) dimensional upstream bandwidth allocaWon and/or

simultaneous transmission within the same channel for QoS and QoE.

•  Added IPv6 & MulWcast QoS •  Expanded 2D upstream scheduling now across mulWple channels •  Increases data capacity with channel bonding similar to other

technologies •  Kept PHY Layer ModulaWon Formats & Old FEC (D3.0 Speed Limit)

BELIEVED DRIVERS FOR DISTRIBUTED ARCHITECTURE

Maximize Coaxial Segment Capacity

Maximize OpWcal Segment (AM OpWcs vs. Digital OpWcs)

Minimize the Facility Space / Power / Cooling

Maximize Long Links to Enable Facility ConsolidaWon

Minimize Costs (OPEX and CAPEX)

AM OpWcs adds Noise decreases CNR which can reduces DOCSIS 3.1 modulaWon

Digital OpWcs can support more wavelengths while not impacWng modulaWon order

Removing the CMTS/CCAP MAC and PHY to the Node will reduce headend space

Digital OpWcs and MAC & PHY in the Node enables Long fiber links

Use of Digital OpWcs (10 Gbps) May reduce Cost when compared with AM opWcs

DAA: TOOL IN A TOOLBOX

•  Benefits of CAA (keeping the MAC/PHY together) — Keeping the MAC and PHY Together avoids protocol and timing

complexities — CAA using I-CMTS Centralises Hardware and Software Processing — CAA using I-CMTS keeps the OSP simple and transparent — CAA using I-CMTS supports large facilities today

•  DAA may be used as a tool in extreme cases: — Significant Space Constraints in Headend or Hub — Massive Service Group (SG) expansion drive use of DAA

o  Expansion from one node per 500 HHP to >10 nodes per 500 HHP o  If locations are fiber starved and/or headend space constraints exist

— Extremely long distance between facility and fiber node o  Broadband Compressed Forward or Remote PHY extends reach to 160 km o  Remote CCAP (MAC/PHY in the Node) extends reach beyond 160 km to enable massive

headend consolidation virtually without limits

DAA is just an addi8onal tool in the the HFC tool bag to be used if/when needed

2 October 2014 16


•  HFC/DOCSIS is a Mass-Deployed Standards Based Technology

•  DOCSIS 3.1 Maximizes Spectrum Capacity of HFC close to FTTP targets

•  Remote PHY/CCAP is a new tool for HFC

•  HFC Network will be well served by Integrated CMTS and AM optics — Density increases will outpace service group growth (while maintaining the

same power/space utilization) —  I-CCAP and HFC will carry well into the 2020 timeframe and beyond —  If/when I-CCAP no longer satisfies the need, the network can transition to

DAA
