Abstract:

A system in accordance With the principles of the present invention employs a loop field test to predict the data rate capability of at least one loop other than the one tested. A local telephone loop is selected for field testing that includes wideband noise testing and signal frequency testing. This reference loop is characterized in response to the results of the field tests and the characterization is used to predict the data handling capability of other similar loops. In an illustrative embodiment one loop Within each binder group terminated at a telephone office is selected as a reference loop and the data rate capability of the other loops Within the binder group are predicted, based on the characterization of the reference loop.
