Enhanced 9-1-1

E9-1-1 service delivers 9-1-1 calls to Connecticut's 103 public safety answering points via an SS7/ISDN network and provides automatic location information (ALI) with a display of the name, address and telephone number of the orignating telephone on a screen at the public safety answering point (PSAP). E9-1-1 has been serving Connecticut from 1990 to the present time. The current system's hardware and software is provided and maintained by AT&T has been in use since 2000.

Replacement of the Enhanced 9-1-1 Telecommunications System

DSET is in the process of replacing the E9-1-1 system. The 9-1-1 PBX and the associated 9-1-1 telephone sets are no longer being manufactured, and the 9-1-1 call handling software loaded on each of the E9-1-1 workstations is no longer supported.

It is the continuing goal of DSET to provide the public with the most technologically advanced 9-1-1 system in the country. It is our objective to develop an Internet Protocol (IP) based 9-1-1 system that can be transitioned into a Next Generation 9-1-1 System (NG9-1-1) as the technology becomes available and is cost effective to implement. The new system will operate utilizing the State of Connecticut Public Safety Data Network for call delivery and be capable of receiving and displaying text messages requesting emergency assistance, photos and videos related to a request for emergency services, and will provide a means to receive 9-1-1 calls originating from the internet. The new 9-1-1 system will be implemented at the 103 E9-1-1 public safety answering points (PSAPs) the Mashantucket Pequot Public Safety, Mohegan Public Safety and four State Police secondary answering points.
