Next Generation 911 (NG911)
History
The current Washington State Enhanced 911 system (E911) telephone network technology was designed in the 1960's and remains nearly unchanged. The current technology consists of point-to-point analogy technologies, in-band signaling and low-speed data transmissions that are both costly and outdated. Although extremely reliable, the current network cannot keep up with new technology and therefore, is unable to provide comparable service for emerging communication devices such as Voice over Internet Protocols (VoIP) phones and is not capable of processing widely used data such as text messaging, pictures, videos or telematics from vehicles.
The transition to Next Generation 911 (NG911) will not occur overnight and will need to progress in phases. Proceeding in phases will ensure first, that the new network and database are a reliable and more robust than the current system. All counties must transition to Phase 2 before the Public Answering Point (PSAP) moves to the final phase deemed Phase 3 (full digital to digital voice and data from start to finish).
An Installation Guide has been developed to provide the PSAPs transitioning to the NG911 network with a list and description of equipment and the installation requirements to successfully deploy to the network. This document will be distributed to the PSAP as part of the pre-migration process. As changes are made, the document will be redistributed.
Statewide transition to NG911 is scheduled to be completed September 30, 2011.
