  1. Cable TV and Data Installation Plain and Simple Doug Marlowe QoS QAM Brought to you by:

  2. Introductions

  3. Let’s Get Started • Why WAS Cable TV Different than Telecom? • Telecom – 1876 – 127 years old • Telecom – Union schools & Apprenticeships • Telecom – Early standards body – Bell Labs • CATV – On-the-Job Training [OJT] • CATV – Vendor control of technology • CATV – Training isn’t always rewarded • CATV – Loss of Monopoly

  4. Challenge your thinking Can my system deliver “Carrier Class” always-on services the way we’re going now? What am I empowered to do to help make my system carrier class? 99.999% availability

  5. Learning Objectives • By the end of this webinar, learners will be able to: • Define the term “best practice” • List new tools and techniques to use in the Data/Cable TV installation process • Explain how the use of best practices and training can measurably benefit an organization

  6. Agenda for Lesson 1 • History of Best Practice Process Engineering • Hawthorne Effect • Deming & IE • ISO 9002 • Baldridge Awards

  7. Agenda for Lesson 2 • Analysis of a Best Practice • Assumptions • Data Acquisition • Analysis • Process Charting • Executing & Monitoring

  8. Agenda for Lesson 3 • Best Practices in: • CATV Installs • Data Installs

  9. Agenda for Lesson 4 • Financial Justification for Training • Definitions • Methods

  10. Definitions • BEST PRACTICES • Step-by-Step procedure that illustrates the best way to do something • MTTR LOW IS GOOD • Mean Time to Repair • MTBF HIGH IS GOOD • Mean Time Between Failure

  11. A Short History of Best Practices • Hawthorne Effect – 1919 • AT&T Western Electric • Turned up the lights – Productivity went up • Turned down the lights – Still went up • Change based on employee input is good

  12. History of Best Practices (cont’d) • Deming & Industrial Engineering • Statistical Quality Control • Time Studies & Work Analysis • Process Development & Improvement • US companies wouldn’t listen to him • Led the Japanese Industrial Rebirth

  13. History of Best Practices (cont’d) • ISO 9002 • Development, Production, Installation, Servicing • Prevention rather than Cure • Baldridge Award • Customer-Driven Quality • Leadership • Continuous Improvement & Learning • Employee Participation & Development • Fast Response, etc…

  14. Analysis of a Best Practice • Assumptions • Is this the best way to do this? • If Yes, why? • If No, what are the alternatives?

  15. Data Acquisition • Field Engineering Studies • What is the task? • What’s the desired result? • What tools are used? • What tests are run? • What’s the paperwork look like?

  16. Analysis • Analysis involves: • Detail common tasks • Detail tools needed • Evaluate motion & movement • Does documentation retell the story?

  17. Process Charting • Process Charting involves: • Create ongoing list of job tasks for each position • Determine skill requirements • Determine training needs • Determine tool and materials lists

  18. Operation • Execution • Now write the “practice” • Now teach the “practice” • On-going Monitoring • Now monitor the use of the practice • Statistical Quality Control • Charts for MTTR and MTBF

  19. Evaluation • Review • The best definition of a best practice is: A. To justify test equipment B. To improve efficiency C. To avoid litigation

  26. Cable TV Installation How about that! According to a CATV training company’s literature, there are over 50 electrical codes and safety standards the average technician needs to know!

  27. CableModem The Steps of Data Installation • Pre-Qualification • Drop Qualification • MAC Address Matching • Inside Wiring • Ingress Testing & Mitigation

  28. CableModem Pre-Qualification • Pre-Qualification • Computer Type • Operating System • Memory • Hard Drive Space Guarantee the installation goes smoothly.

  29. CableModem Drop Qualification B. Drop Qualification • RG59? RG6? • Taps Terminated? • Corrosion? • Adequate Grounding?

  30. CableModem MAC Address Matching C. MAC Address Matching • Server Issues • Did the order synchronize with the hardware delivery?

  31. CableModem Inside Wiring D. Inside Wiring • Exposed Braid? • Defective Splitters? • Impedance Mismatches? • One-Way Distribution Amps? • Kinked, Compressed or Damaged coax?

  32. Definitions • Definitions • BER, Bit Error Rate • MER, Modulation Error Ratio • FEC, Forward Error Correction • Constellation, Size & Shape tells us what type of impairment • Block Error Rate, Upstream Testing [CM1000]

  35. Financial Justification for Training: The Steps • Develop a clear understanding of all job tasks • Identify common mistakes and their costs • Get a clear picture of truck-roll costs • Determine cost of a lost customer due to poor performance • Identify revenue for buy-ups

  36. Financial Justification: The Terms • ROI, Return on Investment • Do the results exceed the cost of training? • NPV, Net Present Value • Value of the investment over a few years • Discounted every year for inflation, etc… • IRR, Internal Rate of Return • ROI, calculated over years of uneven cash flows

  37. Assumptions Training Reduces Truck Rolls by Half • Ask: What did you save? Training Increases Customer Retention by 20% • Ask: What loss did you avoid? Training increases Buy-Ups by 40% • Ask: What Additional Revenue did you gain? Training enables staff to market, sell and service commercial data accounts • Ask: What new revenues did you earn?

  38. Assumptions (cont’d) • Training improves efficiency by 100% • Saves adding head count by 1…SAVINGS? • The right tools improve efficiency • More work done in a day • Increased morale • Employee retention Courtesy of www.arris.com
