Abstract : The paper outlines the technical and planning requirements for providing 1.5 and 2.0 Mbit/s digital transmission on metallic-pair cables. It then describes how a need for test equipment to determine planning rules to maximise 2 Mbit/s working on existing (audio used) cables has led to the development of testers with a wider application. A digital Crosstalk Analyser, for detailed cable performance analysis and collection of planning rule data, and simple barrage testers for pre-commissioning tests are described. Both types of tester are suitable for testing metallic-pair cables at 1.5 or 2.0 Mbit/s. (Author)
