1. Understanding RTT Calling
Real-Time Text (RTT) calling is a communication method that transmits text instantly as it is typed, allowing for immediate interaction between the sender and receiver. This technology is particularly beneficial for people who are deaf, hard of hearing, or have speech impairments, as it provides a text-based alternative to traditional voice calls. RTT is a digital technology and differs from Teletypewriter (TTY), which is an older analog technology. RTT offers several advantages over TTY, including faster transmission speeds, the ability to transmit audio simultaneously with text, and better compatibility with modern communication networks.
1.1. Key Features of RTT Calling
- Real-Time Text Transmission: RTT transmits each character as it is typed, creating a conversational flow similar to a face-to-face conversation.
- Simultaneous Audio and Text: Unlike TTY, RTT can transmit audio alongside text, allowing users to combine voice and text communication as needed.
- Compatibility: RTT is designed to work seamlessly with modern digital communication networks and devices, ensuring broad compatibility.
- Error Correction: RTT includes error correction features to ensure that text is transmitted accurately, even in noisy or unreliable network conditions.
1.2. RTT vs. TTY: What’s the Difference?
While both RTT and TTY serve the purpose of text-based communication for individuals with hearing and speech impairments, there are significant differences between the two technologies:
| Feature | RTT (Real-Time Text) | TTY (Teletypewriter) |
|---|---|---|
| Technology | Digital | Analog |
| Transmission Speed | Faster, transmits text in real-time as it is typed | Slower, transmits text after it is typed and sent |
| Audio Support | Supports simultaneous audio and text transmission | Does not support audio transmission |
| Compatibility | Compatible with modern digital networks and devices | Requires specialized TTY devices and may not be compatible with modern networks |
| Error Correction | Includes error correction features | Limited or no error correction |
| Network Dependence | Designed to work over IP networks | Traditionally relies on phone lines |
| User Experience | Offers a more fluid and interactive communication experience | Can be cumbersome due to slower transmission speeds and lack of audio support |
| Adoption Rate | Increasingly supported by carriers and devices | Being phased out in favor of RTT |
| Emergency Calls | Can transmit special characters or tones to alert emergency operators (availability varies by location) | Also transmits special characters/tones for emergency calls, but operator response may vary |
| Overall | RTT provides a more advanced, efficient, and user-friendly communication solution for individuals with hearing and speech impairments, leveraging modern digital technology to enhance real-time text conversations. | TTY is an older technology that has been essential for communication accessibility but is gradually being replaced by RTT due to its limitations in speed, features, and compatibility with contemporary communication systems. |

8. RTT Calling and Emergency Services
RTT can be a valuable tool for communicating with emergency services when voice communication is not possible or practical.
8.1. Using RTT in Emergency Situations
When making an emergency call using RTT, it’s important to provide clear and concise information about your location, the nature of the emergency, and any other relevant details.
8.2. Limitations and Considerations
- Operator Training: Ensure that emergency operators in your area are trained to handle RTT calls effectively.
- Location Accuracy: Verify that your location information is accurate, as emergency services may rely on this information to locate you.
- Network Reliability: Be aware that network conditions can affect the reliability of RTT transmission, so it’s important to have a backup plan in case RTT is not available.
8.3. Emergency Calls in the U.S.
When making an emergency call in the U.S., iPhone sends special characters or tones to alert the operator. The operator’s ability to receive or respond to these tones can vary depending on your location. Apple doesn’t guarantee that the operator will be able to receive or respond to an RTT or TTY call.
9. Tips for Effective RTT Communication
To ensure effective RTT communication, consider the following tips:
9.1. Be Clear and Concise
Use clear and concise language to convey your message effectively. Avoid jargon, slang, and ambiguous terms that may be difficult for the other party to understand.
