TTY Phones for the Deaf and Speech Impaired

A TTY is a device that enables people who are deaf, hard of hearing, or speech-disabled to use the telephone by typing messages back and forth to one another instead of talking back and forth. In order to communicate, a TTY is required at both ends of the conversation, unless the call is placed through Relay. TTY [teletypewriter], TDD [telecommunication device for the deaf], and text telephone all refer to the same device. 

TTYs are traditionally used in one of two ways: either by placing a telephone handset in to the TTY's acoustic couplers or by directly connecting the TTY to an analog telephone line. Both methods have advantages. In noisy environments, Direct Connect eliminates distracting outside noises and allows the TTY to notify you of incoming calls (with a ring flasher or indication on the text display). It also allows for auto-answer and keyboard dialing capabilities. Acoustic use is convenient when an extra telephone jack is not handy or in environments that do not support an analog phone connection. - Source: Ultratec: Telecommunications for Everyone!
