A TTY (teletypewriter, also known as a TDD or Text Telephone) is a telecommunications device
that allows people who are deaf, hard of hearing, or who have speech or language disabilities,
to communicate by telephone.

TTY device to ensure that it supports digital wireless transmission. Your phone and TTY device

connector cable.
