  About 911

History of 911 in Smith County

  • Pre-1986 Callers that needed to reach police, fire, EMS dialed a 10-digit number to report emergencies to the appropriate agency. These calls were answered by Dispatchers that were employees of each City, County, or other emergency response agency.

  • 1986: 94% of Smith County Voters approved the creation of the Emergency Communications District to design, implement, and administer a county-wide 911 system. The District is managed by a Board of Managers as required and stipulated by the Texas Health and Safety Code Sec. 772. One of the 24 Emergency Communications Districts (ECD) approved in the State of Texas, SC911 is responsible for:

    • Delivering 911 calls with Automatic Number Identification (ANI) and Automatic Location Information (ALI) to any Public Service Answering Point (PSAP) located in Smith County.
    • Administration of 911 Database where caller’s phone and location information are stored retrieved for each 911 call.
    • Administration of the 911 network and routing which deliver the call over the telephone to the appropriate PSAP.
  • 1986: Smith County 9-1-1 Communications District established its offices in the Cotton Belt Building then later at the Woodgate Office Complex. The District began collecting 911 surcharges from landline telephone companies. It was later expanded to included cell phones and today includes Voice Internet Phone (VoIP).

  • 1986-1992: Changed 35,000+ addresses from route and box system to house number and street style addressing for emergency location purposes. Utilizing remitted 911 surcharge funds, designed and prepared 911 networks for deployment.

  • 09/1988: Enhanced 911 (E-911) systems were activated in Smith County. The first District in East Texas and the third such District in Texas. District continues to purchase and maintains 911 Telephony equipment at each Public Safety Answering Point (Tyler PD, SCSO, Lindale PD, Whitehouse PD, and Overton PD)

  • 1986-Present: Smith County 911 operates as a “traditional district”. Ensuring that the 911 system kept up with technology (cell phones, Voice over Internet, TTY/TTD) and maintaining addressing for new development. In addition the 911 telephony equipment at each PSAP is replaced every 5 years to ensure seamless operation with technology improvements.

  • 2009 and Beyond: The 9-1-1 District focuses completely on upgrading and administering the 9-1-1 system. Next Generation 911 (NG911) will utilize the internet and fiber optics to enable 911 callers to provide more than just voice data to PSAPs. NG911 will allow for text messages, videos, telematics, and pictures to be delivered to dispatchers who in turn can share that information with units in the field. These 911 upgrades will pose funding challenges that require the district to direct its resources completely on the Traditional 911 System.
