Cable Crosstalk Impulse Response Measurements

This page describes a collection of measurements which can be used to determine crosstalk impulse responses between twisted pairs of multipair telephone cables.
Gathering this collection of measurements was partially funded by TRIO and use of these measurements is subject to TRIO's conditions which are described in their letter to me; in essence all that TRIO asks is that you share your results with L. S. Lee or Professor David D. Falconer, . TRIO means Telecommunictions Research Institute of Ontario and it is a non-profit research sponsoring organization.

These measurements were described in the following publication.

I am not the author of the measurements. However, we used these measurements in research which was published in the following journal paper.
