The 1980's has been described as the "age of communications." With it has come increasing recognition that modern electronic data transmission provides the critical infra-structure for all aspects of today's information-based society. While telecommunications and its component technology, data communications, has existed for over 150 years, it is in recent years that it has enjoyed explosive growth. This has been due to the confluence of powerful technical, economic and political forces, the most prominent among these being the orders of magnitude advances in information processing capacity and the continuing movement toward the deregulation of the electronic communications industry. The final court-ordered divestiture of AT&T in 1984 caused further acceleration of fundamental industry changes already well underway. A measure of the degree of this change is the explosive growth experienced by the telecommunications industry as a whole, which is estimated to have doubled its total annual revenues in the period 1980 to 1885 from $60 billion to $120 billion.[2]
