    This paper presents the results of an investigation of the relationship between the occurence intensity of different failures in the fault-tolerant control system of three SPC (stored-program control) telephone exchanges and various activity dependent factors in the real time environment of the exchanges. The analysis is based on 475, 439, and 243 failure registrations during 85, 71, and 64 months... View full abstract»

    This paper presents a model to calculate the reliability of communication networks with multimode components. Previous research on network reliability has focused on models in which each component may be in one of two modes, namely, operative or failed. In reality, a component may undergo degradations in performance before a complete outage, and will therefore operate in more than two modes. Tradi... View full abstract»

    As a research project for NASA's Langley Research Center, we developed a variation on MIL-STD-1553B (the military standard for avionics buses) whose goal was increased fault tolerance. The resulting protocol, called implicit token passing (ITP), replaces an explicit token with brief "soundoff" messages from all nodes participating on the LAN. Since every node participates on every "token cycle," b... View full abstract»

    A framework for establishing test-effectiveness criteria can be developed by analyzing the test experience of a satellite program. Such criteria can then be used to design an optimal test plan for future application. This paper reviews a typical acceptance test profile and uses a hypothetical example to illustrate a failure distribution scenario during acceptance testing. A method for improving te...

  • Fault Coverage of Intelligent Switching Networks

    Publication Year: 1986, Page(s):1138 - 1142

    Coverage is a systems parameter describing the effectiveness of self-test procedures chosen for built-in tests (BIT) and other design provisions, such as recoverability, for protection of a system against faults. Classical reliability equations can be substantially modified by the inclusion of the coverage parameter because failures due to insufficient coverage often turn out to be the major cause...

    Despite their diversity, the many factors that enter into the way the quality of telecommunications software is perceived can plainly be linked to the process by which the software is developed. This is fortunate, since the quality of the process is the more easily quantified. In focusing quality programs for telecommunications software on its development, we see that the quality of the final prod... View full abstract»

    In optimizing some property of a system, reliability say, a designer usually has to accept certain constraints regarding cost, completion time, volume, weight, etc. The solution of optimization problems with boundary constraints can be helped substantially by the use of Lagrange multipliers techniques (LMT). With representative examples of increasing complexity, the wide applicability of LMT is il... View full abstract»

    This paper is based on a study conducted by Bell Communications Research of outage data for various stored program control (SPC) switching systems (exchanges) in various Bell Operating Companies. The outage causes were first classified into four basic categories. These basic causes were then subcategorized to further define the causes of failures. View full abstract»
