36 CFR Part 1194 Electronic and Information Technology Accessibility Standards (Section 508 Standards) - Preamble

TTY. TTYs are machinery or equipment that employ interactive text based communications through the transmission of coded signals across the telephone network.

Comment. The Trace Center recommended adding the word "baudot" to the definition of TTY to clarify that the term is not meant to be broader than baudot TTYs. The NAD and other consumer groups, however, supported the Board's definition and encouraged the Board to use the same definition consistently.

Response. The definition for the term TTY is consistent with the definition of TTY in the Board's ADA Accessibility Guidelines and Telecommunications Act Accessibility Guidelines. No changes have been made to the definition in the final rule.
