Emergency Telephone System Board (ETSB)

DuPage ETSB manages the technical systems that provide enhanced 9-1-1; the records of specific incidents are proprietary to its members. Enhanced 9-1-1 systems are a critical and valued state-of-the-art tool for the expeditious response of public safety to citizen requests for emergency service. DuPage ETSB has a head count of 8 full time employees. It should be noted that DuPage ESTB is wholly funded by 9-1-1 surcharge money collected from wireless and wireline telephones.
