How ARMS Monitor 9-1-1 works
ARMS Monitor 911 feature enables the agency to connect its primary PSAP server (CAD output connection) to the ARMS server to receive NENA standard ANI-ALI call details. The NENA standard (http://www.nena.org/) is enforced upon telephone carriers by the government, bringing about some conformity regarding exchanging ANI-ALI data across platforms such as from the telephone system to the CAD server.
The 911 Call window enables the Dispatcher to start a new CAD entry, or appends an existing CAD entry (i.e., existing Open Call), or cancel.
