|
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) between the caller and the call taker. |
|
Enhanced 9-1-1: |
In areas serviced by enhanced 9-1-1, the call is selectively routed to the proper local 9-1-1 center for the callers location, and the 9-1-1 center has equipment and database information that display the caller’s phone number and address to the call taker. The term enhanced 9-1-1 is not synonymous with wireless 9-1-1. |
|
Wireless Phase I: |
When Phase I has been implemented, the call taker automatically receives the wireless call-back number. This is important in the event the wireless phone call is dropped, and may even allow PSAP employees to work with the wireless company to identify the wireless subscriber. Phase I also delivers the location of the cell tower handling the call. |
|
Wireless Phase II: |
Phase II allows call takers to receive both the caller’s wireless phone number and their location information. |
