What is 'priority dispatch' in a CAD or call-processing system?
Answer: A structured protocol that assigns response priority levels to incidents based on severity
Priority dispatch uses standardized protocols to categorize incidents by urgency so the appropriate level of response is sent without over- or under-committing resources.
A dispatcher is asked to perform an 'MDT check.' What is an MDT?
Answer: A Mobile Data Terminal installed in field units
An MDT (Mobile Data Terminal) is an in-vehicle computer that allows field units to receive CAD data, query databases, and update their status without voice radio.
What is the purpose of 'talkgroups' in a trunked radio system?
Answer: To organize users into logical groups that share a communication channel
Talkgroups allow agencies to group radio users (e.g., all patrol officers, all fire units) so they communicate on a shared logical channel within a trunked system.
What is 'E911' (Enhanced 911) compared to basic 911?
Answer: An upgrade that automatically delivers the caller's phone number and address to the PSAP
Enhanced 911 adds ANI (caller's phone number) and ALI (caller's address) to the basic 911 service, giving dispatchers location and callback information automatically.
During a multi-casualty incident, a dispatcher uses a 'patch' function on the radio console. What does this do?
Answer: Connects two or more talkgroups or channels so users on each can hear one another
A patch bridges two or more radio channels or talkgroups so that units operating on different frequencies can communicate directly through the dispatch console.
What does a 'CAD alert' or 'premise flag' warn a dispatcher about?
Answer: A known hazard or special circumstance at a specific address
A CAD premise flag alerts dispatchers and responders to special information about a location, such as violent history, hazardous materials, or special needs residents.
What is the significance of 'call recording retention policies' in a PSAP?
Answer: They define how long recorded calls and radio traffic must be stored before deletion
Retention policies specify the minimum duration that recorded calls and radio logs must be kept, ensuring evidence is available for legal and administrative review.
