# 5 II-7.3000 DJ 192-180-04656 April 20, 1992 The Honorable Carl Levin United States Senate 459 Russell Senate Office Building Washington, D.C. 20510 Dear Senator Levin: I am writing in response to your recent inquiry on behalf of your constituent, Paul Rogers of Charlotte, Michigan. We are aware of the concern expressed by your constituent and the National Emergency Number Association about the provision in our regulation implementing title II of the Americans with Disabilities Act that states "telephone emergency services, including 911 services, shall provide direct access to individuals who use TDD's and computer modems." The apparent concern is that by mandating access to persons using computer modems, the regulation may require that there be access by every format that could be used by a modem, including those that are not compatible with equipment presently used by emergency service systems. That is not the case. The regulation does not require telephone emergency systems to do anything that is technologically infeasible; accordingly, we are interpreting the requirement for access by computer modems to mean only when the modem is using the Baudot format. Until it can be technically proven that communications in another format can operate in a reliable and compatible manner in a given telephone emergency, the public service answering point is not required to provide direct access to computer modems using other formats. This interpretive guidance has been issued by the Department of Justice in its recently published Technical Assistance Manual, which is available from the Office on the Americans with Disabilities Act, Post Office Box 66738, Washington D.C. 20035- 9998, telephone: (202) 514-0301. Sincerely, John R. Dunne Assistant Attorney General Civil Rights Division
