  1. Telephone Power Dependency Do your phones work when the lights go out?

  2. In the old days… • Your dial tone came from the Telephone company Central Office (CO). • The old telephone ran on voltage that came from huge batteries in the CO. • The batteries were kept charged by either the power company or huge generators with weeks of fuel. Ray J. Vaughan, MS

  3. Now • Today’s technology comes with a price… electricity. • Now we need to provide power to our phones, our phone systems • And to the equipment that makes fiber optic networks possible. Ray J. Vaughan, MS

  4. Low Tech Solution • First the easy solution to the big problem • Educate the Public to get a simple or old phone in the house. • Does your phone have a display? Answering machine? Cordless? It has a second cord that goes to an electrical outlet. • When the lights go out, these phones die. Ray J. Vaughan, MS

  5. Excuses • “I have a generator” • Will you be able to call for help if it doesn’t start? • How will you call for the Fire Department if it catches fire? • How many days of fuel will you have available? • Will you run it 24/7? Ray J. Vaughan, MS

  6. Excuses • “I have a cell phone” • How will you be charging it? • Will the towers survive? Ray J. Vaughan, MS

  7. Message: • Have at least one simple phone in the house. • Add this to your agency’s home disaster inventory list. • ( and take the analog TV OFF the list… HDTV and EMhttp://rayvaughan.com/HDTV&EM.htm ) Ray J. Vaughan, MS

  8. Harder Problems to fix The next problem doesn’t have such an easy fix. Ray J. Vaughan, MS

  9. See the Light • Fiber Optic technology allows for huge amounts of voice and data over many miles on a hair-thin piece of glass. • BUT, Glass conducts light, not power. • Something has to convert the digital light signals back into analog electrical signals. • This conversion requires sophisticated electronic equipment that needs power. Ray J. Vaughan, MS

  10. Remote Terminals • Covert Fiber Optic signals to regular phone lines • Powered by the local power utility • 4 to 8 hours of battery power • Usually no backup power source on site • Sometimes called SLC, Subscriber Loop Carrier Ray J. Vaughan, MS

  11. Is this really a problem? • If there is a long (>4 hours) power outage who will be effected? • Everyone. Calling 911 will be impossible. • You. Your Public Safety Facility may be out of service. • Cellular Sites are interconnected with circuits fed by the same RTs Ray J. Vaughan, MS

  12. Wilma Ray J. Vaughan, MS

  13. War Stories • Hurricane Wilma October 2005 • South Florida • Weak Category 2 hurricane • $20.6 Billion in damage • 36 deaths in Florida • Wide area but minimal flooding • Complete power failure in South Florida • 3,241,000 customers, 6,000,000 people without power • Weeks to restore power to many areas Ray J. Vaughan, MS

  14. Communication Failure • As I had predicted, we had major communication failures. • The area effected by Wilma was so wide, resources available in the area were overwhelmed. Ray J. Vaughan, MS

  15. Fire Stations • Our generators came on • VoIP phones, delivered by T1, ran until the RT died • Backup Hotline/Fax Line also on RT • Last resort: UHF Public Safety Radio System • Conventional, Simplex available • No common points of failure Ray J. Vaughan, MS

  16. K&B Radio Site • Hub site for South end of the County • T1s to dispatch, other sites failed • Site in In-Cabinet Mode, 1 RX, 1 TX • Long RT failure • Portable generator set up • Fuel shortage • Misconnection Ray J. Vaughan, MS

  17. Ray J. Vaughan, MS

  18. Ray J. Vaughan, MS

  19. Outage Time Line • Event • Power outage • 4 hour countdown starts • End of wind event, earthquake, disaster • Batteries start to die • No communication • Generators arrive • Fuel shortages Ray J. Vaughan, MS

  20. Katrina Facts • Estimates of the damage: • Initially over 1.75 million people without phone service • 131 Central office effected and 19 of them either destroyed or heavily damaged, serving a total of 187,000 lines. • Cost to restore/replace: $400-500 million • Data and Photo Source: The Central Office Ray J. Vaughan, MS

  29. Action Items • Establish a working relationship with your telco technical expert • Identify your critical locations • Sorry, they’re not ALL critical • How will a Telcom outage effect your process? • What’s convenient and what’s mandatory? • Define backup systems • Public Safety Radio • Telecommunications Service Priority (TSP) Ray J. Vaughan, MS

  30. Action Items 2 • Start with your most critical. Ask: • Where do these lines/circuits need power to operate? • Your end. You better trust your own power • The CO. Batteries, large generators. • Your concern: the ‘everywhere else’ • Is there an automatic generator at each? • Home-Run to CO? Or in a loop? Ray J. Vaughan, MS

  31. Take a look • Learn what to look for • Identify the RTs in your area • Look for generators • Ask questions • Your regular Telco Tech is a great resource for how things really are Ray J. Vaughan, MS

  32. Types of RTs • Above Ground • Underground • Flooding? • In-Building • In someone else’s building • Worst case. You depend on their planning and survival. Ray J. Vaughan, MS

  33. Clues that it’s a RT • Power Meter • Hum or fan noise • Thick cables radiating out • Frequent Telco Trucks parking • Address or RT ID stickers Ray J. Vaughan, MS

  37. On-Site RT • The best solution is to have your RT in your facility • You provide the primary power • You provide the security • Verify fiber route • Route redundancy • Make sure you trust everyone in your loop Ray J. Vaughan, MS

  38. Case Study • K&B Radio Site • Now has an on-site RT • Independent of area RT • On our generator • Redundant fiber routes to CO Ray J. Vaughan, MS

  39. Ray J. Vaughan, MS

  40. Single Points of Failure Better to have multiple: • Remote Terminals • Generators • Fibers and Fiber routes • Copper circuits (if close enough to CO) • Communication Companies Ray J. Vaughan, MS

  41. Generators • Subject to barometric pressure failure during storms • Over/Underspeed due to wind • Water in air intake • Projectile damage • Check the oil change frequency • Oil & Filters on site • Downtime for changes Ray J. Vaughan, MS

  42. Ray J. Vaughan, MS

  43. Flooding • Many RTs and other Telecom facilities in Katrina were flooded. • Fiber can be underwater • Equipment can’t be. • Identify any critical systems in your system that need to be moved higher • Even a CO can be at risk of flooding Ray J. Vaughan, MS

  44. Terrorist Targets? • RTs could be an easy target for anyone wanting to effect communication in an area. • Most are easy to spot when you know what you’re looking for. • Exposed fiber, cables, power • Even simple vandalism at an RT can put you out of service. Ray J. Vaughan, MS

  45. Monitoring • Your Telco should monitor every RT • Investigate every alarm, even open doors • Roll generator when AC power fails • Not when batteries fail Ray J. Vaughan, MS

  46. Regulators: • Require permanent, automatic generators for all new RTs • Encourage RT clustering • Require response levels • Ratios of portable Generators to RTs • Phase out RTs without automatic power backup • Mandate in-building RTs for all Public Safety buildings Ray J. Vaughan, MS
