  1. QUALITY ASSURANCE UPDATE

  2. OUTLINE • Joint Testing – DENCO 9-1-1 • State of Wireless • New FCC Accuracy Standards • New Wireless Class(s) Of Service • Review 9-1-1 B – Problem Call Report

  3. JOINT TESTING • Tested with DENCO June 16 • Tested “border” PSAP’s – Irving PD, DFW Airport, Grapevine & TCSO • Tested transfer keys – did key deliver call to ADMIN number or 9-1-1? • Did PSAP receiving call get full ANI & ALI? • Found and fixed numerous transfer keys programmed to deliver call to ADMIN numbers.

  4. JOINT TESTING • Found and fixed numerous problems with the steering tables that caused call to be delivered without with full ANI - ALI. • We will re-test everything on July 7 in another day of joint testing with DENCO.

  5. STATE OF WIRELESS • 2000 • Residences with landline phones – almost 100% • 9-1-1 calls with class of service = RESD – 34.4% • % 9-1-1 calls from cell phones – 28.1% • 2015 • Residences with landline phones – less than 50% • 9-1-1 calls with class of service = RESD – 4.9% • % 9-1-1 calls from cell phones – 83.4%

  6. STATE OF WIRELESS • May 2016 • Wireless 84.20% • Wireline 13.15% • VoIP 2.65% • Do you have new call takers that have not had WALDO training?

  7. CHANGES COMING TO FCC WIRELESS ACCURACY

  8. FCC REPORT & ORDER – FEB 2015 • For the first time FCC addresses indoor accuracy • Recognized the need for PSAP to have a “dispatchable location” on wireless calls • Based on MAC address of WiFi routers • Also based on a new database called NEAD • Introduced the z-axis to mapping of wireless calls • Phased in over next 8 years • First of new requirements – “within 2 years” from April 2015

  9. DISPATCHABLE LOCATION

  10. CLASS OF SERVICE - WIRELESS • Today • MOBL • WRLS • WPH2 • Will definitely get a new one for “dispatachable locations” – WDISP (?)

  11. FUTURE 9-1-1 CALL FLOW • Wireless 9-1-1 call from residence • Assumes residence has Wi-Fi router & phone registers when in range • Handset that calls 9-1-1“picks up” the MAC of WiFi router and sends it with voice to MSC • MSC sends voice to 9-1-1 tandem and then to PSAP • MSC sends the MAC address to the MPC • MPC dips the NEAD to retrieve the physical address associated with that MAC address • When PSAP sends ALI dip to MPC the physical address of the MAC is returned as the “dispatachable location”

  12. NEW FCC ACCURACY STANDARD • All dates from April 2015 • Wireless provider shall provide (1) dispatchable location, or (2) x/y location within 50 meters: • 2017 : 40 percent of all wireless 9-1-1 calls • 2018 : 50 percent of all wireless 9-1-1 calls • 2020 : 70 percent of all wireless 9-1-1 calls • 2021 : 80 percent of all wireless 9-1-1 calls • All are standards for horizontal accuracy

  13. NEW FCC ACCURACY STANDARD - VERTICAL • All dates from April 2015 • 2018 - Wireless provider shall provide to PSAP’s uncompensated barometric data from any handset that has the capability to deliver barometric sensor date (z axis) • 2018 - All carriers must develop a proposed z-axis accuracy metric to FCC for approval • 2021 – Wireless providers must deploy either dispatachable location or z axis technology

  14. 9-1-1 B • Filled out by call taker during call • Faxed to Tarrant County 9-1-1 • Input in 9-1-1 NET and passed to telco for correction • Not all are “simple” address corrections • Rely on voluntary compliance of customer & their dial tone provider
