Modification of Group 4 Validation System

Abstract

The purpose of this task was the modification of the Group 4 Validation System Software to conform to the CCITT Blue Book Recommendations governing Group 4 Facsimile equipment. The Group 4 Validation System was developed in accordance with the Open Systems Interconnection (OSI) 7-layer architecture. With the release of the CCITT Blue Book Recommendations, the Application/User interface, the Application Layer and the Presentation Layer were either defined and/or significantly changed. In particular the upper layers of Group 4 Facsimile are now structured in accordance with the Open Document Architecture (ODA) and the Document Transfer and Manipulation (DTAM) procedures as specified in the T.400 Series of Recommendations.
