What is Telecommunications Relay Service (TRS)?
Telecommunications Relay Services (TRS) is a communication system that provides telephone communication access to deaf, hard-of-hearing and speech-impaired persons. TRS must be functionally equivalent to telephone communication used by those who do have a communication disability. TRS enables two-way communication by wire or radio between an individual who uses a text telephone or other non-voice terminal device and an individual who does not use such a device.
