  • Patent number: 7443789
    Abstract: A system and method for protection switching in a transmission network is described. A protection switching mechanism comprises a multiplexer, a transmission path for each output of the multiplexer and a remote circuit. The multiplexer has an input coupled to receive an input signal and a plurality of outputs to output a plurality of output signals. Each transmission path is coupled to receive an associated output signal from the multiplexer. The transmission paths further include one or more redundant transmission paths, wherein signals directed to a faulty transmission path are redirected to an associated redundant transmission path. The remote circuit is used to selectively switch a redundant transmission path for a faulty transmission path at a subscriber.

  • Publication number: 20030236876
    Abstract: A user identification is input to a system. The system uses the user identification to select a set of default alarm severity levels. An indication of the selected set of default alarm severity levels is stored in memory. When a predetermined condition occurs in one of the system's function cards, the alarm that is generated is based on the selected default alarm severity level.
