Abstract: A facsimile network includes a plurality of nodes (10)-(14) which are disposed at different locations in the world. An originating fax machine (16) is associated with one of the nodes (10) for transmitting a fax over a local public telephone network (PSTN) (18).

The node (14) then decompresses and de-encrypts the image and converts it to a facsimile image for transmission to a destination fax (20) in a normal mode over a local PSTN (22). A node (12) operates as a central node which can also receive the transmission for routing directly to the fax or for directing via another network link to the node (14).

Abstract: A method for allowing a consumer to access an advertiser's location over a global communication network. A normal broadcast program is broadcast to a class of consumers having a unique signal embedded therein, which unique signal embedded therein is associated with a particular advertiser and a predetermined location on the network. Additionally, the unique signal has encoded therein a unique code that correlates with the location of this predetermined location on the network. When the unique signal is received at a consumer's location, the unique signal is decoded to extract therefrom the unique code. In response to this decoding, routing information to the predetermined location on the network from a consumer's computer on the network at the consumer's location is determined. This determined routing information is then archived in the consumer's computer.
