“…For DM systems to work properly with data signals, the adaptiv e feature must be disabled. The increasing use of telephone channels for transmission of data and facsimile has led to the development of voiceband signal classification techniques [62] which can distinguish voice from various other signals which may be present in a telephone network. Such classifiers can then assign the appropriate coding type and bit rate to accommodate the voice or voiceband data signal.…”
