Housekeeping •  Thank you for attending Cisco Connect Toronto 2015,

here are a few housekeeping notes to ensure we all enjoy the session today.

•  Please ensure your cellphones / laptops are set on silent to ensure no one is disturbed during the session

•  A power bar is available under each desk in case you need to charge your laptop (Labs only)

Service Provider Challenges

Complex and Siloed Competitive Pressure More with Less

Growing Billboard Data Rates •  1 Gb Services today •  Multi-‐Gb coming

Expanding Video Capabilities Aggressive Bundles creating customer churn

Multiple, Complex Networks •  Data, Video, Commercial

Expensive Upgrades •  New Hardware required •  Forklift for “Hub in a Box”

No path for Distributed Architectures

Customer expectations are far outpacing ARPU growth MSO CAPEX and OPEX will stay flat to down

Gigabit to the Home Evolution of Access Networks

Driven by competitive offerings & Video (managed and unmanaged) Multiple Access Technologies support Gigabit to the home DOCSIS 3.0/3.1, PON, Mobility/WiFi

DOCSIS Downstream Scaling Year DOCSIS Rev Capacity Increase CMTS to Plant Connec9vity Details

1998 D1.0 1x 1 ch (6 MHz, 38 Mbps) across 24 FN, 500 HHP/FN

2002 D1.1 6x 1 ch across 4 FN, 500 HHP/FN



2014 D3.0 1500x 32 ch (192 MHz, 1 Gbps) across 1 FN, 500 HHP/FN

2016 D3.1 5400x (2 ch, 384 MHz, 3.5 Gbps) across 500 HHP

2018+ D3.1 14,000x (5 ch, 960 MHz, 10 Gbps), 500 HHP

2020+ D3.1 100,000x (5 ch, 960 MHz, 10 Gbps), 64 HHP Deep Fiber

DOCSIS has incrementally and cost effectively increased its offered bandwidth by >5000x since it started, and has a path to 100,000X

Why DOCSIS 3.1? * Goals *  Achieve 10+ Gbps in the downstream *  Achieve 2+ Gbps in the upstream *  Backwards compatibility with DOCSIS

3.0, 2.0, & 1.1 *  Better spectral efficiency (more bits/

Hz)

* Technology *  OFDM, OFDMA, LDPC *  Expanded downstream and upstream

spectrum *  Improved energy efficiency *  This will allow DOCSIS 3.1 to support services competitive with FTTH. Deployable in today’s HFC networks!

DS Range (MHz) 54* -‐ 1002 108 -‐ 1002 258 -‐ 1218 504 -‐ 1794

# DS Channels 8 SC-‐QAM 24 SC-‐QAM 5 x 192 MHz 6 x 192 MHz

US Capacity 100 Mbps 300 Mbps 400 Mbps 1 Gbps 2.5 Gbps

*Note: In this example the downstream spectrum starts at 54 MHz, but DOCSIS 3.0 signals are carried above 108 MHz.

DOCSIS 3.1 Improved performance *  New physical layer (PHY) technology: OFDM and OFDMA *  Better spectral efficiency than SC-‐QAM

*  Better forward error correction (FEC): low density parity check (LDPC) *  More robust than Reed-‐Solomon FEC used in earlier versions of DOCSIS

*  Higher modulation orders *  Up to 4096-‐QAM in the downstream and upstream, optional to 16384-‐QAM in the downstream

*  Expanded downstream and upstream RF spectrum usage *  Downstream: 258 MHz to 1218 MHz, optional to 1794 MHz (and 108 MHz on lower end) *  Upstream: 5 MHz to 204 MHz

*  Multiple modulation profiles *  Different modulation orders for different modems
