DEVELOPMENT OF TELETYPEWRITER GROUP AN/GGA2(XW-2),
Abstract
Development is reported of a highly efficient, solid-state error-detection and correction system (AN/GGA-2(XW-2)) for use in long-haul digital-data radio teletypewriter links - (i.e., transistorized version of AN/GGA-2(XW-1) developted by Melpar, Inc. This report describes the: (1) ligic mechanical, and electrical design of the equipment, including the modifications resulting from approved Engineering Change 1: (2) checks performed during final-system tests and extended periods of operation, resulting in a 2000-MTBF predictability; and (3) design characteristics that minimize and/or facilitate maintenance. The AN/GGA-2(XW-2) meets or exceeds specification requirements. The possibility of obviating the repeat operation in single errorcorrection is suggested, as are several mechanical-design considerations, which represent refinements that might be incorporated into future models, should the latter be required.
