Abstract
An ingress monitoring device ( ) for monitoring and detecting reverse signals that may include ingress signals. The ingress monitoring device ( ) includes a processor ( ) for resolving the reverse signals into predetermined sub-bands at a first resolution. A power computation circuit ( ) computes a power level for each of the sub-bands. A threshold comparison circuit ( ) then compares the power level that is indicative to the power level of the ingress signals for each of the sub-bands with a predetermined threshold value. When ingress signals are detected by the ingress monitoring device ( ), an alarm signal is sent that indicates the specific communications equipment in which the ingress signals have been detected.
