Abstract

The systems and methods disclosed herein relate to digital data communication systems, and more particularly, the systems and methods relate to systems and methods for facilitation digital communication between a first modem equipped facsimile machine and a second modem equipped facsimile machine. In one example, the system has the second modem equipped facsimile machine system or a first modem equipped facsimile machine that utilizes a modem for data communication, and a telemetry device with a processor for communicating with the first modem equipped facsimile machine and a digital cellular radio for communicating with the processor. The processor relays digital data from the first modem equipped facsimile machine to the digital cellular radio and the digital cellular radio transmits the digital data to the second modem equipped facsimile machine system. This system allows a user to transmit the digital data representing a document. This system facilitates bi-directional communication between a first modem equipped facsimile machine connected to a digital cellular or wireless network via the first telemetry device and a second modem equipped facsimile machine connected to a land (POTS) telephone line or wireless network via the second telemetry device. Data transport over PSTN or wireless networks can be via a circuit-switched or packet data connection.
