What does the acronym TTY stand for in emergency dispatch communications?
Text Telephone
Telecommunications Typewriter
Teletypewriter
Telephone Text Y
TTY stands for Teletypewriter, a device that enables text-based communication over phone lines. This is the standard term used in emergency dispatch for text communication services.
What does the acronym TDD stand for?
Text Device for the Deaf
Telephony Device for the Deaf
Telecommunications Device for the Deaf
Telephone Device for the Deaf
TDD stands for Telecommunications Device for the Deaf, referring to equipment used by individuals with hearing or speech disabilities. This term is paired with TTY in emergency communication systems.
What is the primary purpose of TTY/TDD in emergency dispatch?
To allow video calling for deaf users
To enable text communication for individuals with hearing or speech disabilities
To record all calls automatically
To translate voice into multiple languages
TTY/TDD systems enable individuals with hearing or speech disabilities to communicate via text over telephone lines. This ensures equal access to emergency dispatch services.
What is the standard baud rate used for legacy TTY transmissions?
300 baud
9600 baud
45.45 baud
1200 baud
Legacy TTY devices commonly operate at 45.45 baud using the Baudot code. This fixed low speed ensures compatibility across TTY networks.
In TTY communication, what does the control code "GA" signify?
General Acknowledgment
Go Ahead (your turn to type)
Good Afternoon
Got Answer
"GA" stands for "Go Ahead" and indicates that the sending station has finished and it is the other party's turn to type. It is used to manage the flow of text in TTY calls.
Which character encoding is used by traditional TTY devices?
Morse code
Baudot code
ASCII
Unicode
Traditional TTY devices use the Baudot code, a 5-bit character set designed for teletypewriters. ASCII and Unicode are used in computer systems, not legacy TTY.
Which of the following is the recommended opening phrase a dispatcher should type when initiating a TTY call?
"Hello, go ahead"
"Hello, this is 911, go ahead"
"Please stand by"
"911 Emergency, GA"
The dispatcher should identify themselves and the emergency line by typing "Hello, this is 911, go ahead." This clearly informs the TTY caller of their connection to emergency services.
What does the TTY control code "SK" indicate?
Start Keying
Save Keying
Stop Keying (end of conversation)
Secondary Keying
The control code "SK" stands for Stop Keying and signals the end of the TTY conversation. It informs the other party that no further text will be sent.
When translating TTY messages into voice, what is an essential practice?
Paraphrase heavily to shorten the content
Translate messages verbatim for accuracy
Summarize only the subject matter
Ignore filler words to save time
Translating TTY messages verbatim ensures that all critical information is conveyed accurately. Paraphrasing or summarizing can lead to loss of vital details in emergency situations.
A TTY caller types "CUL8R". How should the dispatcher interpret and voice this?
See you later
Cool 8 R
Call you later
C U 8 R
"CUL8R" is a common abbreviation meaning "see you later." Recognizing and correctly translating such shorthand maintains clear communication between text and voice.
If a dispatcher encounters static or garbled tones on a TTY call, what is the first troubleshooting step?
Switch to voice mode
Adjust the audio gain or volume settings
Ask the caller to hang up and redial
Replace the TTY device
Adjusting the audio gain or volume on the TTY interface can often clear up static or weak signals. This step should be taken before more invasive measures.
When a TTY message is partially unreadable, what should the dispatcher do?
Guess the missing content
Ask the caller to repeat the unclear portion
Skip to the next message
Terminate the call
Requesting the caller to repeat unclear portions ensures message accuracy and prevents misunderstandings. Guessing or skipping can lead to critical errors.
What does the TTY control code "RR" signify?
Repeat Request
Receiver Ready (ready to receive text)
Read Received
Reset Request
"RR" stands for Receiver Ready, indicating that the receiving station is prepared for more incoming text. It is used to manage data flow in TTY sessions.
Which TTY mode allows a caller to speak vocally and receive dispatcher replies via text?
HCO (Hearing Carry Over)
ASCII mode
Baudot mode
VCO (Voice Carry Over)
In VCO mode the caller uses their voice to communicate and reads the dispatcher's responses on the TTY device. HCO is the opposite, where the caller types and listens.
Which practice improves clarity when handling TTY abbreviations?
Expand abbreviations by asking for the full wording
Ignore abbreviations to keep messages concise
Translate abbreviations into other abbreviations
Assume common meanings without asking
Asking callers to expand or clarify abbreviations ensures the dispatcher accurately understands the message. Assuming or ignoring can lead to misinterpretation.
After a TTY software update, incoming calls are not recognized. What should be the initial troubleshooting step?
Reboot the TTY software server
Replace the TTY hardware device
Check system logs for port or driver errors
Switch to voice-only mode immediately
Reviewing system logs can reveal port or driver errors caused by the update. This diagnostic step is essential before attempting hardware or mode changes.
A TTY caller uses many abbreviations that are unclear. What is the best practice for the dispatcher?
Interpret abbreviations based on context
Ask the caller to expand or clarify abbreviations
Omit unclear abbreviations from the report
Replace them with standard codes without checking
Requesting clarification from the caller preserves accuracy and ensures critical information is not lost. Contextual guessing can lead to dangerous misunderstandings.
Which TTY mode should be used when a caller can hear the dispatcher's voice but cannot speak verbally?
VCO (Voice Carry Over)
HCO (Hearing Carry Over)
ASCII mode
Baudot mode
HCO mode allows the caller to hear responses and type their replies. It is appropriate when a caller cannot speak but can listen.
During a VCO call, the dispatcher hears the caller's voice but observes no TTY tones. What is the correct troubleshooting action?
Ask the caller to switch to HCO mode
Increase speaker volume
Check TTY interface settings and ensure receive mode is enabled
Terminate the call and ask the caller to redial
Verifying the TTY interface settings ensures the system is configured to detect incoming tones. Volume adjustments alone may not resolve a misconfiguration issue.
What is the best practice for ensuring message accuracy when translating a TTY message into a voice dispatch report?
Summarize only the essential points
Paraphrase to make it shorter
Read back critical details to the caller for confirmation
Transmit verbatim without confirmation
Reading back critical details allows the caller to confirm or correct any inaccuracies. This closed-loop verification is crucial in emergency communications.
