摘要

Extensive measurements and predictions have been made at data rates up to 10 megabits per second to characterize the digital transmission of binary (+1,-1) signals over balanced pair cables up to 100,000 feet in length. This report presents the results of experimentation concerned with the transmission of digital signals using existing Air Force multi-pair cables and common station equipment. Integrated circuit line drivers and receivers were used for the Balanced Transmission Devices. It has been demonstrated that the transmission capability of existing cable plant can be predicted. Volume I of the report presents the reduced data from the entire test program including laboratory tests, field tests at Patrick Air Force Base, and computer simulation. Volume II is a handbook for the use of Air Force Communication Services to engineer digital cable transmission facilities. The handbook contains tutorial material as well as step-by-step procedures for the design of digital cable systems. (Author)
