  8. 8. THE HISTORY OF DOCSIS • Beginning of Data Over Cable System Interface SpecificaWon (DOCSIS) • Defined support for High-­‐speed Data over HFC • 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) Copyright 2014 – ARRIS Enterprises, Inc. All Rights Reserved. DOCSIS 1.0 March 1997 DOCSIS 1.1 April 1999 DOCSIS 2.0 December 2001 DOCSIS 3.0 August 2006 DOCSIS 3.0 Technology Places Limits on b/s/Hz over ExisWng HFC DOCSIS 3.1: Modernise the PHY Layer & Spectrum Plan 2 October 2014 8
  9. 9. HIGHLIGHTS OF DOCSIS® 3.1 • DOCSIS® 3.1 created with high capacity goals to satisfy subscriber BW demands deep into the 2020 decade — 10+ Gbps DS — 2+ Gbps US • DOCSIS® 3.1 substantially increases the performance of HFC networks via — DS Spectrum expansion — US Spectrum expansion — Modern PHY – OFDM/OFDMA — Modern FEC – LDPC — High modulation orders Copyright 2014 – ARRIS Enterprises, Inc.

  16. 16. 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 Copyright 2014 – ARRIS Enterprises, Inc. All Rights Reserved. 2 October 2014 16
  17. 17. KEY SUMMARY • 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 Copyright 2014 – ARRIS Enterprises, Inc.
