Digital interface system

DETAILED DESCRIPTION The present invention is directed to providing a system for interfacing unclassified information and classified information to and from a pair of discrete radio links.
A means for generating and receiving classified technical data and a means for generating and receiving classified voice coded data are interconnected to an encrypting and decrypting means.
Also electrically coupled to the encrypting and decrypting means, a first transmitting and receiving means and a second transmitting and receiving means transmit and receive information in the uhf spectrum from over satellite links, or, conventionally, in the hf spectrum, respectively.
Appropriate connecting means and coupling means assure that the red side and black side of the encrypting and decrypting means are maintained separate and distinct from one another.
A providing means and submarine-satellite communication connecting means enable a submarine-satellite information exchange over the uhf link.
The prime object of the invention is to provide an improved, more highly reliable communication system.
Yet another object of the invention is to provide a communication system employing a uhf satellite communication link and a conventional hf communication link.
A further object is to provide a communication system fabricated to assure a red/black separation of information.
Yet another object of the invention is to provide a communication system having the capability for handling voice coded data and tactical data and the transmission and reception thereof through uhf satellite links and hf conventional links.
Another object is to provide a highly reliable system for handling encrypted and unencrypted information.
These and other objects, advantages and novel features of the invention will become apparent from the following detailed description of the invention when considered in conjunction with the accompanying drawings.
