    Description: The Defense Communication System will be moving rapidly toward providing switched digital service to it's users within the next ten years. The principal driving force in the transition to a digital system is the requirement for high performance secure voice service. Additionally, the anticipated data requirements in this time frame can be handled most effectively by a digital network. The characteristics of a switched digital network which impose timing and synchronization requirements on the system design are presented. Several alternative approaches to implementing a timing subsystem suitable for a switched digital communications system have been considered. These include pulse stuffing, independent stable clocks, and clock correction techniques. The advantages and disadvantages of each approach are discussed relative to both the strategic and tactical communication system requirements.

    Description / Table of Contents: Zusammenfassung Ein quadratisches Optimierungsproblem, in demq(x) =a T x +x T Qx eine indefinite Zielfunktion ist, kann mitSwarups Optimierungsansatz (c T x + α)(d T x + β) nur gelöst werden, wenn der Rang vonQ gleich zwei ist; wennQ definit ist, muß der Rang vonQ gleich eins sein.
    Notes: Summary A quadratic programming problem, whereq(x) =a T x +x T Qx is an indefinite objective function, can be solved withSwarup's approach of optimizing (c T x + α)(d T x + β) only if the rank ofQ is two; ifQ is definite, the rank ofQ must be one.
