"DEVICE AND METHOD FOR THE DETECTION OF DIGITAL DAMAGE AFFECTING A MODULATION CHANNEL PULSE CODE (PCM) THE AMOUNT IN A DIGITAL DECOMMUNICATION NETWORK". A device and a method for detecting digital damage affecting an upstream pulse code modulation (PCM) channel on a digital communication network (36) involves: receiving, via a digital PCM modem (38) interconnected to the network digital communication (36), a random sequence of digital values selected from a constellation of digital values transmitted by the PCM channel upstream of the digital communication network (36); the establishment of distributions of the digital values received, each distribution corresponding to one of a plurality of time intervals; and the derivation of the distributions of the types of stolen bit loss and digital loss that affect the PCM channel upstream of the digital communication network (36), for each time interval.
