Excerpt
Excerpt: Why are text telephones required? In drafting the Americans with Disabilities Act, Congress cited the discriminatory effects of communication barriers in particular and directed the Access Board to include requirements for communications for persons with sensory impairments in its ADA Accessibility Guidelines (ADAAG). Scoping and technical criteria were developed for assistive listening devices, emergency communications systems, visual alarms and auxiliary notification devices, volume controls at public telephones, and public text telephones for persons with speech or hearing impairments. What is a text telephone? ?Text telephone? is a generic term for devices that provide access to real-time telephone communications for persons with hearing or speech impairments. Like computers with modems, text telephones provide some form of keyboard input and visual display output to callers and receiving parties connected over standard telephone lines and networks. A call from one text telephone can only be received by another--and compatible--text telephone. The devices, however, can be used by and between both hearing and non-hearing persons.
