A Nationwide Communication System for the Hearing Impaired: Strategies Toward Commercial Implementation. Final Report.
Allan, Daniel S.; And Others
The purpose of this report is to assess the viability of developing commercial computer communications networks to provide communications services to the deaf community on a nationwide basis. Access to this network is considered for existing Baudot/Weitbrecht Telecommunications Devices for the Deaf (TDDs) and ASCII terminals with Bell modems. The basic communications needs of the deaf and the potential market for a Deaf Network and Associated Services are defined. Examination of key concepts used to determine the commercial feasibility of DNAS, including supply and demand considerations and subsidy mechanisms, is followed by a review of current telecommunications provisions for the deaf, particularly Deafnet, a computer-based communication demonstration system. After discussing factors involved in a national commercial vendor-based framework for DNAS with special consideration of tariff design, the commericial performance of DNAS as it might be offered to a specific target population is evaluated. Preliminary commercial feasibility estimates are given for three alternative tariff structures and two supplier cost models. The study indicates that DNAS is likely to be commercially viable in the long term, although initial subsidies will be required. An appendix discussing the shift to cost-based pricing in the telephone industry, a glossary, and 26 references are also provided. (ESR)
