A particular method includes receiving first data indicating a measured strength of an ambient electromagnetic signal in a particular frequency range during a particular time period and at a particular location. The method also includes receiving second data indicating a bit loading within a portion of a wireline network in the particular frequency range during the particular time period. The portion of the wireline network provides service within a service area proximate to the particular location. The method also includes determining a correlation of changes in the second data during the particular time period to changes in the first data during the particular time period. The method further includes identifying at least one issue associated with the wireline network based on the correlation.
