1. Looking Beyond 1G to the Ultra-Broadband Future October, 2015

2. 2 The Future = More Sources: Ericsson Mobility Report, Cisco VNI More Broadband Uses Connected devices per consumer 2014 (3) 2020 (7) IP traffic per capita 2014 (8GB) 2019 (22GB)

3. 3 And, Less Service Provider consolidation = fewer but stronger competitors Fewer distinct end to end networks – all IP 100 telecommunications M&A activities in 2014 1 Increasing number of cable acquisitions of telco assets and vice versa 1 IDC Research 2 American Customer Satisfaction Index Consolidation of data, voice and video onto CCAP platforms Convergence of fixed and mobile core networks HSD SDV VOD CCAP Less user tolerance for poor experience Average % satisfied of Americans satisfied with Pay TV service declined from 65% to 63% from 2014 – 2015 2 More choices can = higher defection rates

5. A Decade of Revolution Ahead 5 Burgeoning Global Demand for Broadband Services Service Providers Fighting for Relevance & Profitability 40 years of IT innovation will happen in 10 years in cable & telecom networks 10X mobile broadband traffic 2014 – 2020 1 3 connected devices per man, woman, child by 2019 2 2 ZB global IP traffic in 2019 (66X that of 2005) 2 AT&T’s John Donovan: “by 2020, 75% of network functions will be virtualized” 60% of service providers say SDN / NFV are essential technologies over next 5 years 4 100 telecommunications M&A activities in 2014 3 Competition between telcos and MSOs accelerates Increasing OTT and service provider partnerships Sources: 1 Ericsson Mobility Report, June 2015; 2 Cisco VNI Report, 2015; 3 IDC Research; 4 Heavy Reading

6. 5 Key Trends 6Proprietary / Company Confidential 1 1 Access network densification: geometric growth in number of access end points to meet broadband coverage and capacity demands 2 2 3 3 4 4 5 5 Network convergence: fixed and mobile networks integrating to provide ubiquitous ultra-broadband services Service provider convergence: providers expand portfolios into adjacent domains (cable for MSOs; mobile for MNOs) organically or through M&A Network transformation: service providers re-thinking architectures and moving quickly toward cloud + SDN / NFV for networks and data centers Programmable Networks: resultant transformed networks enable exponential growth in offerings from service providers to end users and third parties
