Local 911 Call Centers - Emergency Telecommunications System Functionality
Terminator Description
The 'Emergency Telecommunications System' represents the telecommunications systems that connect a caller with a Public Safety Answering Point (PSAP). These systems transparently support priority wireline and wireless caller access to the PSAP through 9–1–1 and other access mechanisms like 7 digit local access numbers, and motorist aid call boxes. The calls are routed to the appropriate PSAP, based on caller location when this information is available. When available, the caller's location and call–back number are also provided to the PSAP by this interface. This facility may also be used to notify the public – residents and businesses – of emergency situations using a Reverse 911 capability.
