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 t

elephone.

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-c

ompatible phone and be in the TTY mode to

place o

r receive calls. Note that most digital wireless

devices are TTY-compatible.
