A possibility of using wideband noise for qualification and troubleshooting of digital subscriber lines

This paper analysis the actual usefulness and importance of wideband noise as one of electrical parameters of symmetrical copper pairs. By the results of measuring wideband noise on the real system in practice on copper pairs with different conditions on them, 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.
