Abstract
A method for providing spectral containment over telecommunications service lines is provided. The method includes selecting a filter having spectral characteristics corresponding to a predetermined passband. The method also includes connecting the filter in series to at least one loop used to provide at least one telecommunications service to a customer. The method further includes activating service over the at least one loop. The filter attenuates signals transmitted on frequencies outside of the predetermined passband over the at least one loop.
