Abstract
For diagnostic and trouble-shooting purposes, an audio/voice signal capture mechanism is adapted to be interfaced with a time division multiplexed (TDM) transport path-cascaded echo canceler and compression arrangement for an integrated access device (IAD). The audio/voice signal capture mechanism captures a ‘snapshot’ of the audio/voice signals by storing a prescribed number of seconds of audio/voice path signals transmitted in both directions through the IAD, and time stamping the captured audio/voice signals and associated signaling events of interest. In this way, the invention operates as a ‘virtual’ oscilloscope, as it is able to capture pertinent data for any voice call problem along with an associated time stamp event log.
