Definitions

  • the present invention relates to apparatus and methods for routing information over communications networks, and more particularly, to apparatus and methods for routing facsimile information over communication networks.
  • the transmission of graphical information such as facsimile (fax) information is a complex interchange where two fax machines exchange information over conventional telephone circuits.
  • facsimiles When facsimiles are sent to local destinations, they are local calls and are relatively inexpensive.
  • fax facsimile
  • about 41% of U.S. business telephone expenditures are fax related and 74% of those fax calls use long distance connections.
  • long distance charges can be a significant component of the total operating cost of a fax machine.
  • the cost of transmitting data over computer networks is relatively independent of the local-long distance characterization.
  • LANs local area networks
  • WANs wide area networks
  • conventional fax machines cannot connect to and communicate directly with computer networks.
  • conventional fax machines cannot convert the fax information into electronic mail, or attachments to electronic mail.
  • keypads of conventional fax machines do not provide for entering electronic mail addresses.
  • a routing apparatus which selectively links a graphics transmission equipment such as a fax machine to a first network using a telephone line, and/or to a second network such as a computer network.
  • the apparatus has a plurality of ports to permit communication over telephone and computer networks.
  • the apparatus also has a display which provides a visual feedback to users.
  • a keypad is provided to accept destination e-mail addresses corresponding to conventional fax numbers, and which may be suitably encoded strings representative of electronic mail (e-mail) addresses.
  • the apparatus detects whether the user wishes to send a fax over the first network or the second network by decoding a number entered as a destination. If the user wishes to transmit the fax using the telephone network in a conventional fashion, the apparatus simply forwards the fax transmission over the telephone network. Alternatively, if the fax number conforms to a predetermined protocol which indicates that the transmission is to be routed over a computer network, an electronic mail address is generated based on the entered destination. The fax transmission is captured, converted into a suitable format, and forwarded to the destination as electronic mail, or as an attachment to electronic mail.
  • the apparatus can be deployed singly or in pairs to link fax machines over the network. If operating alone, the apparatus can route transmissions from an attached fax machine to a computer connected to the computer network. The electronic mail and/or electronic mail attachments can be read by the computer at the destination. Also, if operating alone, the apparatus can receive e-mail and convert it to a fax format, and print the document on the associated fax machine.
  • a second routing apparatus connected to the computer network is deployed for driving a second fax machine.
  • the electronic mail is routed over the computer network.
  • the electronic mail (e-mail) is received and processed by the second routing apparatus.
  • the second apparatus converts the e-mail and/or e-mail attachments back into a fax compatible format and directs a fax transmission to the attached second fax machine.
  • the pair of fax machines can thus communicate using the computer network to reduce long distance charges.
  • the apparatus establishes a link between an international network of fax machines and an international network of computers exchanging electronic mail. Fax transmissions are flexibly routed over a plurality of communication networks to minimize long-distance charges. Further, the apparatus allows users to send and receive electronic mail using conventional fax machines. Destination addresses are conveniently and quickly generated by converting suitably encoded keypad entries into e-mail addresses.
  • information sent over a conventional fax machine is converted and stored in a digital format suitable for transmission to other fax machines or computers with a resulting reduction in communication costs.

Abstract

L'invention concerne un appareil (100) qui relie un télécopieur (120) à un réseau téléphonique (126) et à un réseau informatique (139). Cet appareil (100) permet à l'utilisateur d'acheminer sélectivement la transmission de télécopies sur un réseau informatique (134, 139 et 146) de façon à réduire les coûts de transmission à grande distance. L'invention concerne également un bloc de touches (112) et un écran (114) permettant d'entrer des adresses de destination et de fournir à l'utilisateur des informations visuelles en retour. Lorsque la transmission sur la ligne téléphonique (125) est nécessaire, l'appareil (100) relie directement les télécopieurs (120 et 134) au système téléphonique (126 et 132). Toutefois, si la transmission de télécopie doit se faire sur un réseau longue distance (139), y compris l'Internet, l'appareil (100) intercepte la transmission de télécopie, convertit l'information en format électronique approprié de manière à pouvoir l'adjoindre à un courrier électronique, et achemine la transmission vers sa destination (152) sur le réseau longue distance (139) ou l'Internet afin de réduire les frais de transmission de télécopie à grande distance facturés par la compagnie téléphonique. L'appareil (100) peut également accepter du courrier électronique et le convertir dans un format acceptable de façon qu'il puisse être reçu par les télécopieurs classiques.
