Abstract:
A facsimile transmission relay apparatus for improving call success rates in long delay environments, comprising:a first bi-directional telecommunication interface for receiving a first facsimile signal from a transmitting facsimile device and retransmitting a second facsimile signal from a receiving facsimile device via a first network; a buffer for storing said first and second facsimile signals; a second bi-directional telecommunication interface for receiving said second facsimile signal and retransmitting said first facsimile signal via a second network to said receiving facsimile device; and an information processor coupled to said first and second interfaces for monitoring messages from the transmitting and receiving facsimile devices and for generating messages to the receiving facsimile device to maintain communications with the transmitting facsimile device via the first and second networks, wherein said information processor buffers signals received via said first and second bi-directional telecommunications interfaces in said buffer to avoid collisions with signals transmitted via said second network from the receiving facsimile device.
