3 © 2011 JDSU. All rights reserved.JDSU CONFIDENTIAL & PROPRIETARY INFORMATION2  Home Certification Overview –What is Home Certification? –Why do we need it? –What is the technology?  Certifying the Home –Home Certification Challenges in the field –What affects Services –What can and should be done  Questions and Answers Today's Agenda

4 © 2011 JDSU. All rights reserved.JDSU CONFIDENTIAL & PROPRIETARY INFORMATION3 Why Home Network Certification?  Estimated that 70-75% of all trouble calls are due to problems inside the home.  Estimated that between 90-95% of troubleshooting root cause of service issues inside a home is coax path related –Replacing connectors, splitters, faulty coax, etc… –Craftsmanship –This is consistent with both QAM and MoCA services  QAM signals are more susceptible to issues –QAM signals are maxed out –Now more susceptible to other issues  Greater customer satisfaction through a more reliable network  Home certification has been proven to reduce costly repeat truck rolls.

5 © 2011 JDSU. All rights reserved.JDSU CONFIDENTIAL & PROPRIETARY INFORMATION4  The best answer is: – to provide short and long term customer satisfaction by: Reducing repeat visits Reducing overall truck rolls over time Reducing unnecessary Refer to Maintenance calls »Providing test data to tech responding to escalation Being prepared for future technologies  Another step closer to One and Done Why should we do this “certification”?

6 © 2011 JDSU. All rights reserved.JDSU CONFIDENTIAL & PROPRIETARY INFORMATION5 Find and Fix Dilemma Missing marginal installations often leads to 3-1 find and fix scenario Field Tech $125 install tech truck roll $125 network tech truck roll Network Tech Field Tech $125 service tech truck roll 3 truck rolls that should have only required 1, 3-1 At $125/roll, cost for repair was $375 or $250 extra cost! At $100/month average customer revenue, and a 50% margin, that means that about 5 months of profit are gone from this customer Saving only 1.5 - 2 events per month, pays for a field instrument that can help prevent this scenario in less than 12 months.

7 © 2011 JDSU. All rights reserved.JDSU CONFIDENTIAL & PROPRIETARY INFORMATION6 What goes wrong?  Excessive attenuation caused by too many splitters or long cable runs  A drop amplifier that does not pass the entire required spectrum  Un-terminated splitters or outlets  Poor crimping or other connector issues  Cable faults or other conductor flaws  Many of these flaws are caused by poor craftmanship!

8 © 2011 JDSU. All rights reserved.JDSU CONFIDENTIAL & PROPRIETARY INFORMATION7 Why do we need to certify the home?  Upcoming technologies will require an even more robust home network.  MoCA supports a full-mesh network between all nodes, procedures must be modified to rate all segments, not just from the initial splitter to outlets but also STB-to-STB segments that may not include the initial splitter.  Any number of components could be the cause, including bad connectors and splitters, amplifiers, band pass filters, un-terminated cables or excessive noise, distortion or interference that affects the part of the spectrum.

9 © 2011 JDSU. All rights reserved.JDSU CONFIDENTIAL & PROPRIETARY INFORMATION8 Benefits of Certification Customer doesn’t call Boss Boss doesn’t get mad at tech Tech doesn’t take it out on dog Happy Customers Happy Boss Happy Tech Happy Dog

10 © 2011 JDSU. All rights reserved.JDSU CONFIDENTIAL & PROPRIETARY INFORMATION9 Find Root Cause of Service Issues  Troubleshooting Philosophy: –Quickly find and fix the root cause of 80-90% of in-home related issues – the Coax –Allow operators to determine all Triple-Play & other newer services will work before connecting any CPE devices! Certify the home’s coax plant over all frequencies is correct It doesn’t matter what service is running on the coax Future proof for eventual additional revenue

11 © 2011 JDSU. All rights reserved.JDSU CONFIDENTIAL & PROPRIETARY INFORMATION10  Remember the Goal –  Help assure that work (service, install, etc.) is done correctly the first time, and verified with quantitative test data, hence reducing repeat service calls.  You can ensure that the proper tests are taken for every required job and the test data is recorded.  Testing is consistent across all techs and jobs – Test data is reconciled against the work order system Quality standards are enforced for each job Why do we need to do this

12 © 2011 JDSU. All rights reserved.JDSU CONFIDENTIAL & PROPRIETARY INFORMATION11  Testing –Tap to TV, Modem, or Set Top Box The span of the network the Service /Install Tech controls. Using the test equipment provided  Standardization All customers get the same tests All Techs run the same tests Apple to Apples  Verification –Ensure that the testing was done correctly  Assurance –Ensure that corrective action is taken if required  Reporting –Provide compliance information to managers and technicians  Data Collection What is Home Cert?

13 © 2011 JDSU. All rights reserved.JDSU CONFIDENTIAL & PROPRIETARY INFORMATION12  Because you are the one with the tool belt  Because you can move the test equipment around while you troubleshoot. –Outlet to Ground Block to Tap  Know at once when you have fixed, or found the location of the problem  Provide measurement history at that location for future reference. Why this, instead of other back office tools?

14 © 2011 JDSU. All rights reserved.JDSU CONFIDENTIAL & PROPRIETARY INFORMATION13  Run the tests at jobs that require a test to be run –Results are compared to user defined Pass/Fail limits –Pass/Fail limits should be such that a fail means “must fix”  Fix problems uncovered –Or validate they need escalation ( via test at Tap)  Re-run test to verify correction of problems  Results are reported in terms of number of tests: –that actually were performed versus number that SHOULD have been performed –Number of tests passed  Reporting is available grouped by System, Manager, Supervisor, or Technician.  Goal is to achieve and maintain high compliance and passing numbers Summary so far

15 © 2011 JDSU. All rights reserved.JDSU CONFIDENTIAL & PROPRIETARY INFORMATION14 Reduce repeat rate – lowering repeats caused by marginal signal conditions Create a system wide standard for acquiring & interpreting test results  Results in standard and consistent procedures that ensure quality based on quantitative test data Improve productivity by reducing repeat service calls Improve customer satisfaction levels, as customers do not have to keep experiencing the same problem Provide a central repository for test data provides management reports, trends for data analysis, efficiency of technician and productivity By successfully implementing Home Certification

39 © 2011 JDSU. All rights reserved.JDSU CONFIDENTIAL & PROPRIETARY INFORMATION38 Certification: The tech needs to know how to….. Know which job types to test Know which outlet to test Know which channel plan is the right one to use Know how to name and save the test Know how to understand what failed, if there is a fail Know how to fix or report what failed, know how to escalate and verify why that escalation is needed. Know how and when to synchronize the meter with the server.

40 © 2011 JDSU. All rights reserved.JDSU CONFIDENTIAL & PROPRIETARY INFORMATION39 New and upcoming?  MoCA  WiFi  DNLA

41 © 2011 JDSU. All rights reserved.JDSU CONFIDENTIAL & PROPRIETARY INFORMATION40 MoCA Parameters  MoCA uses the existing coaxial cable plant in a subscriber’s home as the connecting media for devices on a home network.  MoCA 1.1 provides a 16-node solution  175 Mbps will always be available to more than 95 percent of the nodes  BER target of 1 x 10-9.  Communication between devices on a MoCA network is controlled by a node designated as the network coordinator (NC)  Nodes need to be able to transmit RF carriers at 55 dBmV to overcome splitter port to port isolation. Sometimes 2 splitters.

42 © 2011 JDSU. All rights reserved.JDSU CONFIDENTIAL & PROPRIETARY INFORMATION41 An In-Home Network, Physical Layer NC

43 © 2011 JDSU. All rights reserved.JDSU CONFIDENTIAL & PROPRIETARY INFORMATION42 MoCA Node Discovery  A node joins a MoCA network by listening for a beacon signal from the NC  After receiving the beacon signal, a new node sends an admission request to join the network.  If no beacon is heard, the new node assumes it is the first and begins transmission of its own beacon.  MoCA 1.1 completes the probe and beacon tasks faster than its predecessor MoCA 1.0. This allows an increase in the maximum number of nodes from eight to 16 and provides a throughput increase from 100 to 175 Mbps network throughput for 95 percent of the nodes.

44 © 2011 JDSU. All rights reserved.JDSU CONFIDENTIAL & PROPRIETARY INFORMATION43 MoCA Optimization  In addition to cable, the subscriber’s plant also contains splitters and sometimes amplifiers. MoCA equipped devices also need to be able to communicate through high-isolation output ports, in the forward as well as reverse directions.  This is accomplished using a form of orthogonal frequency division multiplexing (OFDM) that is dynamically tailored to the individual paths in the subscriber’s coax network.  “Probe” signals are periodically sent to the MoCA nodes on the plant to determine frequency response at each of the OFDM subcarrier frequencies.  The optimal combination of constellation and frequency for each node is determined to achieve a BER of 1 x 10-9, resulting in constellations that can range from no symbols to 256-QAM  Because the electrical characteristics of the plant can change when the subscriber adds or removes devices, probes are sent on a periodic basis, and the OFDM scheme is changed as required.

45 © 2011 JDSU. All rights reserved.JDSU CONFIDENTIAL & PROPRIETARY INFORMATION44  Operates between 850 and 1525 MHz  Each channel is 50 MHz wide in 1.1 or 100 MHz wide in 2.0  In some cases, more than 1 channel is used at the same time to allow transport of 2 different logical networks.

49 © 2011 JDSU. All rights reserved.JDSU CONFIDENTIAL & PROPRIETARY INFORMATION48 MoCA 2.0 Details  MoCA 2.0 (June 15, 2010) - Similar to MoCA 1.1 but with the following differences: –Three new modes of operation: Basline Mode: –400+ Mbps MAC throughput –700 Mbps PHY Rate –Single 100 MHz Channel Enhanced Mode –800+ Mbps MAC throughput –1.4 Gbps PHY Rate –Two bonded 100 MHz Channels (“Channel Bonding”) “Turbo” mode for a point-to-point configuration that allows: –500+ Mbps MAC throughput between two connected devices when operating in Baseline mode –1+ Gbps MAC throughput when operating in Enhanced mode –All three modes now have an extended frequency range 500 MHz through 1650 MHz (center frequencies) –Backward compatibility with MoCA 1.0 and 1.1 devices MoCA 2.0 devices can operate at MoCA 2.0 speeds while MoCA 1.x devices are communicated to at their maximum respectable speeds on the same network NOTE: MoCA 2.0 is different hardware than previous MoCA 1.1 HW versions

50 © 2011 JDSU. All rights reserved.JDSU CONFIDENTIAL & PROPRIETARY INFORMATION49  WiFi has already surpassed wired in home networks –Apple sold 3 million IPads within the 1 st 3 months of it’s release –There are now approximately 108 million IPhones worldwide  While WiFi is widely used for data, up until now it has been deemed not reliable enough for video due to interference from such things as microwave ovens and cell phones.  802.11n now provides for data rates up to 600Mbs on a 40MHz wide carrier  802.11n also provides for the concept of multiple input multiple output (MIMO), providing for a maximum of four transmit antennas and four receive antennas.  802.11n also provides for Dynamic digital beamforming,it monitors and adjusts the Wi-Fi signals based on real-time events that could affect performance. In combination with the 4 x 4 antenna scheme, beamforming can provide a 12dB-to-25dB improvement in reliability  With these 2 innovations, video can now be delivered reliably over wireless What does the future hold for home networks? 49

51 © 2011 JDSU. All rights reserved.JDSU CONFIDENTIAL & PROPRIETARY INFORMATION50  Digital Living Network Alliance (DLNA) promotes wired and wireless interoperability of PCs, CEs, and mobile devices.  A DLNA device works like any other network device by discovering other DLNA-enabled hosts.  It learns their capabilities and exposes these features on the device's control display.  Through DLNA, a media server can be located and then summoned to play or display a stored family photo, movie, music file, etc.  DLNA-certified devices include TVs, PCs, set-tops, routers, game consoles, tablets, Blu-ray and DVD players, smartphones and audio receivers.  The organization says it has certified more than 9,000 different devices.  More than 440 million DLNA-certified devices were installed in users’ homes by the end of 2010 More not too distant future stuff, DLNA 50

53 © 2011 JDSU. All rights reserved.JDSU CONFIDENTIAL & PROPRIETARY INFORMATION52  We are NOT certifying the whole house (just yet)  We ARE certifying an outlet –Which is way better than not certifying anything  The big reasons we don’t certify ALL outlets now is……. –We don’t know how many there are –We don’t want to spend the time doing all outlets 2-3 minutes per outlet, plus ingress scan, plus time to save, etc. Now – what are we NOT doing?

54 © 2011 JDSU. All rights reserved.JDSU CONFIDENTIAL & PROPRIETARY INFORMATION53 To completely verify the home network we would need to …. Verify signal quality at the Ground Block or Point of Entry Verify wiring from POE to each outlet  Loss  Noise/Ingress of each leg  Frequency response of each leg If we meet specs at the POE and verify wiring performance from POE to outlet….then We don’t need to run RF/MODEM tests at each outlet, do we?

55 © 2011 JDSU. All rights reserved.JDSU CONFIDENTIAL & PROPRIETARY INFORMATION54 Point of Entry (POE) Filter and Splitter Isolation  A MoCA filter (aka: POE filter) performs two jobs. –First it prevents the MoCA signal from entering a neighbors house by placing a filter at the input to the home network –Second it gives MoCA a point of reflection for the signal because it requires the signals to bounce from output port to output port.  There is approximately 30 dB of port to port isolation on a 2 way splitter POE MoCA/POE Filter 30 db down from one port to the other 55 dBmV in 25 dBmV out

56 © 2011 JDSU. All rights reserved.JDSU CONFIDENTIAL & PROPRIETARY INFORMATION55 What if……we could test multiple outlets…at once? TAP We could do all our up and downstream tests at the Ground block… Attic Crawl Space Splitter …And then verify that we had good performance from the ground block to each outlet? X With 1 button push?

57 © 2011 JDSU. All rights reserved.JDSU CONFIDENTIAL & PROPRIETARY INFORMATION56 Mini-Probes… Each probe : has an F-Connector and a mini-USB port its own unique identifier letter ( A, B, C, D, etc) Sweeps 5-1500 Mhz – forward and reverse Has FDR function to determine distance to faults Has noise detection to listen for and detect ingress Meter connects to one probe via USB, and controls test and displays results on screen.

58 © 2011 JDSU. All rights reserved.JDSU CONFIDENTIAL & PROPRIETARY INFORMATION57  Put a probe at each location inside the home where a Set-top- box or Cable Modem will be located (or is desired to be tested)  Connect that probe to the POE looking into the home toward CPE (ie: drop cable, ground block, or main split)  Connect the probe to the meters USB port Probe Setup 57 USB to Mini-USB Point of Entry or Main Split POE = Point of Entry CPE = Customer Premise Equipment

59 © 2011 JDSU. All rights reserved.JDSU CONFIDENTIAL & PROPRIETARY INFORMATION58  Verify Frequency Response to and from each outlet So lets sweep forward and reverse from 5 Mhz to 1500Mhz  Calculate loss from Ground Block to each outlet  Listen for ingress on each leg With some built in intelligence we can map the wiring system too! We want to ….

60 © 2011 JDSU. All rights reserved.JDSU CONFIDENTIAL & PROPRIETARY INFORMATION59  Shows POE to outlet frequency response for Forward and Reverse Sweeps  Why not do 5-1500 in one sweep?  We want good resolution at the reverse band edges Sweep Trace – Freq Response 59 Upstream Freq ResponseDownstream Freq Response – with MoCA filter in place

61 © 2011 JDSU. All rights reserved.JDSU CONFIDENTIAL & PROPRIETARY INFORMATION60 See each path’s frequency response  Sweep graphs can identify many issues in the coax network –Relative levels are shown at multiple frequencies to give users more information than numbers alone can express By looking at the sweep response users can identify why the test failed the limits of the service plan: –Too much overall loss, adjacent points’ difference too great, overall highest loss to lowest loss (peak to valley) too great –Users can see and interpret from the sweep response signal degradation caused by: Frequency cut offs due to poor splitters or inline filters Amplifiers eliminating the return or MoCA bands Excessive attenuation Reoccurring standing waves Frequency suck outs 60

62 © 2011 JDSU. All rights reserved.JDSU CONFIDENTIAL & PROPRIETARY INFORMATION61 Seeing how everything is connected  Shows what is connected –The probes should determine how what it sees is connected and where those elements have common connections –Each element can be shown on the topology map including: splitters, filters, amplifiers, and found mismatches –Users can easily identify if unexpected elements are discovered and trace where those elements are located before beginning to troubleshoot the coax network Note: Not every topology can be mapped with 100% accuracy though most common configurations can. Filters and amplifiers in the path can lead to inaccurate common points being shown on the topology map and are highlighted yellow when present. 61

64 © 2011 JDSU. All rights reserved.JDSU CONFIDENTIAL & PROPRIETARY INFORMATION63  For whole house certification – Keep It Simple  Summary results has all that is needed at a glance: –Pyramid screen –Overall pass/fail –Pass/fail for each upstream and downstream path from POE to each outlet –Ingress noise limit check –Pass/fail for MoCA (if desired) between all devices in the customer premise Whole home results screen…

65 © 2011 JDSU. All rights reserved.JDSU CONFIDENTIAL & PROPRIETARY INFORMATION64  We can test RF downstream and upstream and DOCSIS at the ground block or point of entry, and then…  We can test multiple outlets and know how many were tested –One-Button test for all tested outlets saves time –Identify what the inside wiring problem is –Identify where the problem is –Identify hidden amps, splitters and filters True “Whole House” Certification. Now – we have whole house Home Certification !

Add 3db to above figures to allow headroom.
