Abstract
A method of monitoring a data transmission transmitted over a telephone line includes the first step of determining if a data transmission is incoming or outgoing over a telephone line. In the second method step, a modem is configured to monitor a receive portion of the telephone line if the first step determines that the transmission is outgoing. The modem is configured to monitor a transmit portion of the telephone line if the first step determines that the transmission is incoming. In the third method step, a data signal is detected from the data transmission. The method may include the further step of maintaining statistics corresponding to the data signal. The data transmission may be a facsimile transmission. The data signal may be any one of a DCS signal, an MCF signal, and an RTP signal.
