Abstract
An ingress monitoring device (400) for monitoring and detecting reverse signals that may include ingress signals. The ingress monitoring device (400) includes a processor (430) for resolving the reverse signals into predetermined sub-bands at a first resolution. A power computation circuit (435) computes a power level for each of the sub-bands. A threshold comparison circuit (445) 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 (400), an alarm signal is sent that indicates the specific communications equipment in which the ingress signals have been detected.
