Telecommunication Devices for the Deaf; a Selective Update

Article excerpt

TELECOMMUNICATION DEVICES FOR the deaf (TDDs), portable devices that allow deaf and hearing-impaired persons to communicate over the telephone, are essential for providing direct telephone library service to these patrons. Since the last TDD update in the November 1985 American Libraries, many features that were then considered luxuries have now become standard features in all but economy models. These include a direct connection between the telephone and TDD, keyboard dialing, built-in memory, memory dialing, and programmable autoanswer. The newest feature offered, electronic voice, is also destined to become standard. Electronic voice alerts hearing call recipients that the incoming call is a TDD call.

This update focuses on TDDs from the two manufacturers that have emerged as the leaders in the industry. Please note that the information presented was gathered from their promotional literature and does not list all features. The manufacturers should be contacted for full details.

Information on other TDD manufacturers and products can be obtained by contacting local agencies and organizations specializing in services to the deaf. Manufacturer: Krown Research Inc. 10371 W Jefferson Blvd. Culver City, CA 90232 213-839-0181
