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 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%
% 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%
% calls from cell phones – 83.4%

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 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 calls
2018 : 50 percent of all wireless calls
2020 : 70 percent of all wireless calls
2021 : 80 percent of all wireless calls
All are standards for horizontal accuracy

13. NEW FCC ACCURACY STANDARD - VERTICAL
All dates from April 2015
Wireless provider shall provide to PSAP’s uncompensated barometric data from any handset that has the capability to deliver barometric sensor date (z axis)
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 NET and passed to telco for correction
Not all are “simple” address corrections
Rely on voluntary compliance of customer & their dial tone provider
