How RTT Mode Works: Protocols And Transmission Methods

In this subheading, we will delve into the inner workings of RTT mode and explore the protocols and transmission methods involved. RTT mode utilizes various communication protocols such as Real-time Transport Protocol (RTP), Session Initiation Protocol (SIP), and Interworking Function (IWF) to facilitate the real-time transmission of text.

RTP is a key protocol used in RTT mode to ensure the delivery of text data packets over networks. It provides mechanisms for packetization, timing, and delivery monitoring. SIP, on the other hand, is responsible for initiating and terminating RTT sessions, as well as managing the necessary signaling between the communicating devices.

Additionally, the Interworking Function plays a crucial role in enabling interoperability between different RTT implementations and legacy TTY (Text Telephone) devices. It ensures seamless conversion and translation of text streams between RTT and TTY formats.

In terms of transmission methods, RTT mode can utilize both wired and wireless networks. It can operate over traditional telephone lines, cellular networks, internet-based VoIP networks, and even through satellite connections, enabling individuals to communicate using real-time text across various platforms and devices.
