    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»

    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...

    Publication Year: 1986, Page(s):1047 - 1051
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (472 KB)

    Permanent and temporary faults can be subdivided into classes with respect to their properties in the electrical domain and the time domain, e.g., sudden solid, marginal, gradual, intermittent. Strategies in the design of the central control of the AXE digital switching system are described. The automatic locating of permanent and temporary faults is based on a modular hardware architecture and st... View full abstract»

  • A Timeout-Based Congestion Control Scheme for Window Flow-Controlled Networks

    During overload, most networks drop packets due to buffer unavailability. The resulting timeouts at the source provide an implicit mechanism to convey congestion signals from the network to the source. On a timeout, a source should not only retransmit the lost packet, but it should also reduce its load on the network. Basedon this realization, we have developed a simple congestion control scheme u... 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»

  • Approximate Markov Modeling of High-Reliability Telecommunications Systems

    The reliability model of a system with redundancy but only a single repairman is Markov only if the component failure rates and the repair rate are constants. This paper introduces a method with which a reliability analyst can formulate an approximate (time-homogeneous) Markov model for a system with 1-out-of-2 redundancy when repair is nonexponential (repair rate is time-dependent). This approxim... 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»

    Railway interlocking systems are the technical equipment of the operative train traffic control, regulating the routes and the speed of train units. Their basic task is to ensure the safety of the train traffic and shuntings, and to avoid dangerous situations. The safety provided by the interlocking system at normal operation and at breakdowns, namely the safety against dangers, must be proved by ... View full abstract»
