58 -- VOICE DIGITIZING EQUIPMENT FOR EVALUATION OF APPLICABILITY TO AIR TRAFFIC CONTROL APPLICATIONS POC Anthony (Buzz) Cerino, POC, (609) 485-5640. It is the intent of the FAA Technical Center to evaluate current technology in the area of voice coding equipment to determine applicability for use in international air/ground communications. Suppliers willing to assist in this effort are encouraged to contact the above for the purpose of submitting equipment for evaluation. Subject equipment should consist of two parts: 1) a voice encoder and 2) a voice decoder. The voice encoder shall be capable of translating an input analog (voice) signal into a digital bit stream. The decoder shall perform the reverse operation. The following minimum requirements shall apply: a) maximum bit rate of 4800 bps (including all FEC); b) intelligibility should be maintained down to a BER of 2x10-2; c) operate in a half duplex push to talk (PTT) mode; and d) maximum throughput delay of 80msec. All equipment should include complete documentation on system operation, interfacing characteristics, and company policy regarding algorithm licensing for an international market. Any equipment meeting the above criteria and submitted for evaluation will be considered for FAA application. Any equipment/documentation submitted shall be considered proprietary and not be provided to any competitor. The FAA will not be responsible for any costs incurred by any contributor as a result of their participation, and there is no guarantee of any solicitation as a result of this study. Equipment should be available for submission no later than May 31, 1995, after which no updates in software or hardware will be considered. All equipment/documentation will be returned following the evaluation. (0102)
