• DOCSIS 3.1 Modernizes the RF Data Technology • AM Optical Performance Improvements and Density Increases • Broadband Digital Return (BDR) 200 MHz (even digital forward is being
explored)
INDUSTRY TRENDS Evolu&on of the Delivery Network Con&nues:
Technology
• Space/Power Efficiency Improvements and Density Increases • CAA (I-CCAP Dominance in the market over MHA) • DAA moves from Telco to Cable (Remote PHY versus Remote MAC & PHY)
Access Architecture
• Service Group Reduction (Fiber closer to subscribers and fewer amplifier cascades)
• Expand Spectrum (Mid-split / High-split upstream and 1.2 GHz downstream) • Facility Consolidation or Only Access Network Equipment in Facilities
(CCAP/OLT)

DOCSIS 3.1 GETTING THE MOST OUT OF YOUR HFC
2 October 2014 7
Copyright 2014 – ARRIS Enterprises, Inc. All Rights Reserved.
• 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

• 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
