Abstract
A method of detecting signals propagated on a carrier medium includes the step of determining a noise threshold level, relative to a noise floor on a carrier medium, such as for example POTS wiring. A peak threshold level is then determined relative to peaks of a data signal. A data threshold level is then calculated utilizing the noise threshold level and the peak threshold level. For example, the noise threshold level and the peak threshold level may be averaged to calculate the data threshold level. A data signal pulse is then detected on traversal of the data threshold level by the data signal.
