Abstract:
1. A method for determining a change in network-generated crosstalk levels caused by a multi-line phone comprising: determining, using a signal analyzer, a first crosstalk level between a first line pair and a second line pair of a multi-line phone caused by the multi-line phone, wherein determining the first crosstalk level further comprises: determining, using the signal analyzer, a second crosstalk level between each of the first line pair and the second line pair of the multi-line phone, the second crosstalk level being determined when the first line pair and the second line pair are coupled to a first predetermined length of network line pair cable; and determining, using the signal analyzer, a change of network generated crosstalk levels caused by the multi-line phone by comparing the first crosstalk level to the second crosstalk level.
