Abstract:

High speed, 4-wire circuit switching equipment was developed by the United States Air Force for universal use in tactical and fixed plant envi ronments. Its design is based on the time-divi sion-multiplex technique and, in association with the highway switching principle, comprises the switching and transmission network. The equip ment is fully transistorized and adaptable for application in local, tandem, and long, tandem, and long haul switching modes. The transmission characteristics of this equipment are such that it is directly compatible with any transmission network that consists of HF, VHF, UHF, troposcat ter, microwave, metallic circuits with or without carrier multiplex or a combination thereof for processing voice, digital data, graphics, etc., with a quality better than present commercial standards. High quality transmission character istics make possible its insertion into a commu nication system consisting of six tandem links of approximately 6000 miles, where the of a typical link may be as much as 2500 miles. The equipment has been extensively factory and field tested with highly satisfactory results and presently is operational within an integrated system environment performing local and long haul tandem switching functions.
