A possibility of using longitudinal balance for qualification and troubleshooting of DSL lines

This paper examines the actual usefulness and importance of longitudinal balance as one of many electrical parameters of symmetrical copper pairs. Through the results of several experiments on copper pairs with different types of significant faults, but also by measuring longitudinal balance on the real system in practice, this paper attempts to show the actual usefulness and importance of this parameter. In this manner, this paper intends to make the process of measuring the electrical parameters of symmetrical copper pairs more reliable and usable for reliable detection of various types of faults.
