Frequently Asked Questions
What is Basic 9-1-1?
Basic 9-1-1 means that when the three-digit number is dialed, a call
taker/dispatcher in the local public safety answering point (PSAP),
or 9-1-1 call center, answers the call. The emergency and its
location are communicated by voice (or TTY)
What is E9-1-1?

to the proper PSAP for the caller’s location, and the PSAP has
equipment and database information that display the caller's phone
number and address to the call taker.
What is wireless Phase I?
When Phase I has been implemented, the call taker automatically
receives the wireless phone number. Phase I also delivers the

a PSAP based on cell site/sector information.

Phase II allows call takers to receive both the caller's wireless
phone number and their location information. The call is routed to a
PSAP either based on cell site/sector information or on caller
location information.
