Assistive communication devices
TTY (Text Telephony) and TDD (Telecommunications Device for the Deaf) allow individuals who are deaf, hard of hearing, or have speech or language disabilities to communicate by telephone.
When a user types his or her conversation on a TTY keyboard, it is transmitted as tones through the telephone. Tones are received by the other person’s TTY, translated into text and displayed on the screen. In order to use the TTY network, you must have a TTY-compatible phone and be in the TTY mode to place or receive calls. Note that most digital wireless devices are TTY-compatible.
