Data Communications Systems

Data communication systems were originally developed to support a variety of the firm’s strategic reconnaissance systems activity. It was natural to seek to provide links from remote unattended listening stations to central station command and control functions. These data systems were often developed to withstand severe environmental and reliability tests; some systems include multiple airborne and ground-based receivers. One of the early data communications systems developed was a multi-channel ultra high frequency digital data link, whose innovation was its abiltiy to be conveyed over a single standard military voice channel. In 1972 the company developed one of the first commercial grade telephone to computer data modem devices.
