TTYänimisestä

TTYänimisestä (Finnish for "about TTY") refers to the use of a teletypewriter (TTY) or a computer terminal that emulates a TTY for communication purposes. TTYs were originally mechanical devices used for sending and receiving messages over telephone lines, but they have since been replaced by digital communication methods. However, TTYs remain in use for individuals with hearing impairments or speech disabilities, as they provide a text-based communication method that can be used with a telephone.

TTYs operate by converting typed characters into electrical signals that are transmitted over a telephone line. The receiving TTY then converts these signals back into typed characters. This allows for real-time, text-based communication between two parties. TTYs can be connected to a telephone line using a modem, or they can be integrated into modern communication devices, such as smartphones and computers.

In addition to their use for communication, TTYs can also be used for other purposes, such as accessing certain online services and databases. For example, some government agencies and public utilities use TTYs to provide information and services to individuals with hearing impairments.

TTYs are an important tool for individuals with hearing impairments or speech disabilities, as they provide a means of communication that is accessible and easy to use. However, they are also a relic of the past, and their use is declining as digital communication methods become more prevalent. Nonetheless, TTYs remain an important part of the communication landscape for many individuals, and their use is likely to continue for some time to come.
