Correct Answer - Option 1 : Real Time Text Messaging
Explanation:
RTT stands for Real Time Text Messaging.
It is a technology that allows text to be sent immediately as it is created through wireless handsets that use IP-based technology on networks that support RTT. With RTT, there is no need to press a “send” key as there generally is for SMS, chat, or other types of texting.
A recipient can read a message while the sender types it. Instant text transmissions are similar to the instantaneous exchange of information in voice conversations over the phone and can be critical for emergency calls to 911.
Advantages of using RTT are:
- RTT can eliminate the need to purchase specialized devices, such as TTYs, to send text in real time over wireless phones.
- Calls using RTT can be initiated and received using the same ten-digit numbers used for voice calls.
- Both parties to an RTT call can send and receive text in real time at the same time, unlike TTYs, which requires turn-taking.
- RTT is more reliable than TTY technology over IP networks – this means there will be less garbling and fewer drop-offs on calls.
- RTT provides callers with more characters for typing than TTYs do. For example, with RTT, you can use the “@” key, alphabets in multiple languages, and emojis, allowing conversations using the full “international character set.”
- Both RTT and voice can be used, either at the same time or interchangeably, during the same call.
