  • Telecommunications is one of the fastest growing business sectors of modern information technologies. A couple of decades ago, to have a basic understanding of telecommunications, it was enough to know how the telephone network operated. Today, the field of telecommunications encompasses a vast variety of modern technologies and services. Some services, such as the fixed telephone service in developed countries, have become mature, and some have been exploding (e.g., cellular mobile communications and the Internet).

  • Many services running on modern digital telecommunications networks require accurate synchronization for correct operation. For example, if switches do not operate with the same clock rates, then slips will occur and degrade performance. Telecommunication networks rely on the use of highly accurate primary reference clocks which are distributed network wide using synchronization links and synchronization supply units.

  • Progress in information technology (IT) has been remarkable, but the best truly is yet to come: the power of IT as a human enabler is just beginning to be realized. Whether the nation builds on this momentum or plateaus prematurely depends on today’s decisions about fundamental research in computer science (CS) and the related fields behind IT. The Computer Science and Telecommunications Board (CSTB) has often been asked to examine how innovation occurs in IT,
