Abstract: Transmission characteristics of digital networks make the direct use of analog fax machines on a digital network unfeasible. A method and apparatus for interfacing between an analog fax machine and a digital network is described. A communication session over the digital network is controlled by an interface connected to the fax machine, the method for controlling the communication session comprising the steps of: receiving a plurality of signals from the fax machine; converting a predetermined subset of the plurality of signals into a plurality of digital signals; and commuicating with a remote station using the plurality of digital signals, wherein the remote station is connected to a destination fax machine. To deter dropped calls, interface lowers transmission rate of fax data from transmitting fax machine below actual data rate capability of network and receiving fax machine. In addition, interface delays transmission of fax data from transmitting fax machine by sending false Failure to Train messages during training.
