TDD - Telecommunications Devices for the Deaf

What is TDD?

A telecommunications device for the deaf (TDD) is an electronic device that allows typed text communications over a standard phone line.  The device is typically about the size of a big laptop, contains a standard keyboard, and possesses small LCD screen on which text typed remotely appears.  Sometimes a remote operator will translate communications between speech and text as appropriate.
