SECURE & EASY ACCESS TO RELAY SERVICESA relay is used to connect or control circuits with different voltages and currents, or with different speeds. The switch has an armature that moves contacts and a yoke that keeps the circuit in continuity between the moving contact on the armature and the circuit track on the printed circuit board (PCB) via a wire.Relays are found in long telegraph lines where the weak signal received at the intermediate station can control a contact. They also are used in radio and television equipment for switching frequencies or power levels.
The TRS program is a free telecommunications service that links conversation between people with text telephones or telebraille devices and those who use standard telephones. It is a state-wide program operated under contract by Sprint and regulated by the Tennessee Public Utility Commission.Unlike TTY calls, TTS calls do not require a special telephone and can be placed from any payphone with no coins required. Local calls are free, and long-distance calls are charged at the same rate as a standard telephone call.

This registration must include the name and address of the user, information about the user's disability, a statement that the CA will provide a speech-to-speech or text-to-speech relay service, and a personal identification number.
