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.
