Abstract
A system for transmitting data in real-time over a standard digital data network, or an analog network, whereby the facsimile data is sent in data packets on the digital data network. A number in an area being dialed by a facsimile device is monitored to determine whether the number is either a local number, inter-lata number, intra-lata number or a long distance number and whether the area is being serviced by the digital data network. Based on the determination, a first POP (point-of-presence) receives the facsimile transmission, converts the facsimile transmission to a rasterized form, and then converts the rasterized data into "packets" of data, which are sent over the digital data network, one packet at a time, to a second POP. The second POP receives the packets over the digital data network, converts the packets to the rasterized form, and then reconverts the rasterized data using the G3 protocol, to be sent over the analog telephone network to the destination facsimile.
