Medical Center. SPONS AGENCY American Telephone and Telegraph, New York, N.Y. PU_,? DATE 68 NOT 152p. FDPS PRICE EDPS Price MP' -$0n 75 HC-$7070 DESCRIPTORS Audio Equipment, Equipment Evaluation, Equipment Utilization, *Exceptional Child Services, *Physically Handicapped, Sensory Aids, *Telephone Communication Systems AESTPACT A study by American Telephone and Telegraph investigated the use of standard Bell equipment in meeting the needs of the disabled for telephone service. Results revealed that all disabled persons who are able to communicate orally can initiate and terminate a call and carry on a conversation when the correct types of equipment are found, especially when push button dials are universally available or when an operator is available. The monograph presents information on the difficulties encountered in using the phone and on equipment found useful. Each phone, headset, or modification is described through words and by photographs; advantages and disadvantages are noted. Several factors influencing the choice of telephone equipment (answering in time, access, and family use) are considered. Evaluation of the patient and the equipment is discussed in regard to the amount of physical function present and the testing and matching of equipment for various disabilities. Choice of telephone, assistive devices, special services for summoning aid, use of the phone for home business, and coin phones for wheelchair users are also mentioned.
