3 We have heard of Google Fiber in the US 3

4 But now FTTH competiton also gains momentum outside US 4

5 Strategic options for cable to compete with FTTH A: Stay on DOCSIS 3.0 Expensive node splits soon especially driven by upstream traffic Assymmetric speeds no Gbit/s product B: Migrate to FTTH Enormous investment Will take ~10 years C: Upgrade to DOCSIS 3.1 Will over an x year time frame cost the same as staying on DOCSIS 3.0 Capex can be as low as only ~20% of the FTTH investment Can be rolled out very fast no new cables Will provide FTTH speeds to consumers 5

6 DOCSIS 3.1 architecture and technology choices DOCSIS 3.1 or CCA or DCA DCA P2P or PON 10GPON CCAP or CMTS D-CCAP So Huawei offers D-CCAP R-PHY or MACPHY MACPHY Virtual or Physical CCAP Physical 6

7 Summary of logic behind Huawei technology choices Why DOCSIS 3.1 Notes Lower TCO than DOCSIS 3.0 Node splits delayed with >4 years due to more spectrum and higher efficiency Competition with FTTH operators Due to capability to offer Gbit/s symmetrical products with much lower investments Backwards DOCSIS compatibility Invest in future proof technology without having to migrate customers Cable modems with long future 2*US and 2*DS from day 1 (unlike DOCSIS 3.0) Synchronization possibility (for MBH) New revenues - wholesale Symmetry for enterprise customers New revenues - BSOD Ongoing development Full duplex will provide symmetrical capacity reusing 3.1 technology principles Why DCA Better SNR Reduced need for central office floorspace Reduced cooling costs in central office Notes Higher modulation means more DOCSIS capacity and even higher DVB-C robustness Equipment moves to existing fiber node street cabinets Equipment moves to existing fiber node street cabinets Why PON Will provide smooth FTTH migration path Saves access fiber Notes OLT also supports xdsl, HA and xpon networks Up to 80% compared to ethernet P2P which requires 2 fibers for each remote unit Why D-CCAP Analogue fiber replaced by digital One platform only for DVB-C, VoD and DOCSIS Local DVB-C BC frequency planning Notes Saves trunk fiber, provides IP redundancy, reduces complexity and O&M costs Saves costs and increases spectrum flexibility Each Service Group can have its own frequency plan Why MAC-PHY No complex timing transfer Lower latency More benefits from future vccap Why physical MAC-PHY Better stability Notes Increases stability Less signal propagation time since MAC is closer to the user Virtualized MAC not realistic in the near future, so OLT virtualization fits best with MACPHY Notes Cloud based DOCSIS solutions still need to mature 7

8 Example: TDC Denmark upgrades to 100% DOCSIS 3.1 D-CCAP Turnkey rebuild project 1,2 GHz downstream / 204 MHz upstream Full Huawei solution responsibility, incl. 3rd party amps and passives Huawei takes over capacity planning and buildout for 6 years Very fast rollout 100% DOCSIS 3.1 coverage EOY 2017 Target is 95% 4k QAM downstream and 1k QAM upstream No analogue fiber left even in coax plants with no DOCSIS Total analogue TV shutoff executed February 2016 Huawei U2000 NMS and adaptation to in-house developed NMS Support for existing DVB-C QAM based VoD service Full spectrum OFDM upgrade possible just with software (5*DS blocks) Solution for FM radio service in high US split network agreed (but not used) Solution for basic video multiplexing in D-CCAP Solution for passive cooling of street cabinets implemented 8

9 Business case drivers DOCSIS 3.1 D-CCAP OpEx CapEx Revenues O&M costs for AM systems No node splits for x years Reduced churn to FTTH Increased signal robustness ~10% capacity gain (DCA) Business services Less CO floorspace Avoid new trunk fiber Mobile backhaul Less CO cooling HFC refresh less faults Better PNM less calls No CMTS HW optimisation Dismantle video mux Long lifetime cable modems Better reputation 9
