A method for monitoring at least one telephony communication n-bit channel, wherein one of the bits is a parity bit, includes sampling the parity bit of the n-bit channel. A probable bit error rate is derived from the sampling of the parity bit. The probable bit error rate can be compared to a pre- determined bit error rate value to determine if the at least one telephony communication n-bit channel is corrupted. If the at least one telephony communication n-bit channel is corrupted, the at least one telephony communication n-bit channel is re-allocated to an uncorrupted and unallocated telephony communication n-bit channel. Further, at least one unallocated telephony communication channel can be periodically monitored and error data accumulated to indicate the quality thereof.

Procédé de contrôle d'au moins un canal de télécommunications de n bits, où un des bits est un bit de parité, consistant à effectuer l'échantillonnage du bit de parité du canal de n bits. Un taux probable d'erreurs sur les bits est calculé à partir de l'échantillonnage du bit de parité. Le taux probable d'erreurs sur les bits peut être comparé à une valeur prédéterminée de taux d'erreurs afin de déterminer si ledit canal au moins de télécommunications de n bits est altéré. Si c'est le cas, ce canal est réaffecté à un canal de télécommunications de n bits inaltéré et non affecté. De plus, au moins un canal de télécommunications non affecté peut être contrôlé périodiquement et les données d'erreurs peuvent être accumulées afin d'indiquer leur qualité.
