Development of a Validation System for Group 4 Facsimile Equipment.

Abstract

The report is divided into three principal areas: a system overview, system design and system operation are presented. The system overview reviews the overall validation system requirements and the system structure used to meet these requirements. It also outlines the software and hardware design taken to satisfy the CCITT Recommendations governing the Teletex Protocol structure for Group 4 Facsimile equipment. The system design, Section 3, discusses in detail the system design. It also reviews the hardware and software design approaches for implementing the Teletex protocol structure. This structure is consistent with the seven-layer Open Systems Interconnection (OSI) reference model, which provides a basic framework for protocol development. The system operation, Section 3, details the operation of the validation system and explains the parameterization required to define the protocol variants for the testing of a Group 4 terminal.
