Facsimile communication system
First Claim
1. A facsimile communication system for communicating picture data among facsimile machines comprising:
- at least one second facsimile machine for sending and receiving picture;
at least one second facsimile machine other than a G4 facsimile machine for sending and receiving picture data; and
a facsimile terminal controller connected to said second facsimile machine through a network, other than a store and forward switching network and connected to said G4 facsimile machine through a store and forward switching network for converting picture data of a second facsimile standard received from said second facsimile machine into picture data of a G4 facsimile standard and sending the converted picture data to said G4 facsimile machine and for converting picture data of a G4 facsimile standard received from said G4 facsimile machine into picture data of said second facsimile standard and sending the converted picture data to said second facsimile machine.

Abstract
A facsimile communication system for communicating picture data among facsimile machines including two types of facsimile machines having different coding algorithms for picture data and different resolutions. One type of facsimile machine is directly connected to a store and forward switching network and the other type of facsimile machine is connected to the store and forward switching network through a facsimile terminal controller. When the facsimile terminal controller receives picture data from the other type of facsimile machine, it decodes the received picture data, encodes it by the coding algorithm of the first type of facsimile machine and sends it to the store and forward switching network. When the facsimile terminal controller receives the picture data from the store and forward switching network, it decodes the received picture data, encodes it by the coding algorithm of the other type of facsimile machine and sends it to the other type of facsimile machine. When a resolution of the image data received from the store and forward switching network is different from a resolution of the picture data to be sent to the other type of facsimile machine or vice versa, the facsimile terminal controller converts the image data to the appropriate resolution.
