Definitions

  • a command/signal will trigger the Alarm Block circuit.
  • the Fail Detector Block can be implemented using part of the microcontroller used for other functions with or without the Dual Tone Multi- frequency Receiver Block.
  • the purpose of the Alarm Block is to inform the functional failure by an audible or visual way.
  • the Alarm Block circuit is triggered by the Fall Detector Block and the Telephonic Central Office Alarm System is activated.
  • the failing module/card can thus be found.
  • the circuit can be implemented with transistors, relays, drivers, leds, etc., and an example circuit is shown in figure 23.
