Abstract :
The evolution of a successful telecommunications monitoring device is described from its inception to its installation across Canada. This product, called the service discrimination unit (SDU), is a powerful and flexible platform for digital processing of signals on a T1 span. Signal processing is provided by Motorola DSP56001 digital signal processors and control functions are provided by Motorola 68HC11 processors. The SDU´s first commercial application is to apply the DSP processing power to determine if the traffic being carried on a telephone line is voice, modem data, or facsimile data
