Abstract
An interface device for faxing documents over a wireless network includes circuitry for emulating the public switched telephone network (PSTN) for communicating with an analog fax machine. The circuitry receives and stores a document image from the fax machine. It then prompts a wireless transceiver to establish a call connection. Once a call connection is created to a destination fax through the wireless network the interface device transmits the stored document image. The inventive method includes the steps of communicating with a fax over by means of one protocol to receive a document image, storing the document image, and transmitting the document image by means of a second protocol.
