The Americans with Disabilities Act (ADA) of 1990 requires all interstate and intrastate telephone companies to provide Telecommunications Relay Services (TRS). Communication through TRS must be functionally equivalent to telecommunications services used by those who do have disabilities.
Telecommunication relay services enable persons with limited speech and/or hearing who use TTD's and TTY's, or TT's, to communicate by telephone with non-TTY users. (Source: National Institute on Disability and Rehabilitation Research)
