Abstract

It provides various services including G4 facsimile system and image information communication by accessing digital communication network and simultaneously allocates common hardware and software in G4 facsimile system that can communicate with G3 facsimile system by connecting to analog communication network. It is a wasteful, inefficient, system that runs on different operating systems, making it impossible to access ISDN and use G3 communications software. To this end, in the G4 facsimile system, the G3 communication control unit and the G4 communication control unit integrate and configure common hardware and software. Thus, it can be controlled from one operating system and can provide G3 C facsimile functionality.
