1. A method comprising: receiving at least one alert indicative of a system fault, a system failure, or both; selecting one or more fiber optic lines for examination based, at least in part, on the received at least one alert, the one or more fiber optic lines supplying a transmit signal and a receive signal to/from a remote transmission station; selecting at least one property of the transmit signal and/or a receive signal to be monitored; monitoring, using a data acquisition unit, the transmit signal and/or receive signal in the one or more fiber optic lines; retrieving, by an element management subsystem (EMS), information corresponding to the at least one property for a predetermined period of time; generating a visual representation of the retrieved information; performing an analysis of the retrieved information and/or the visual representation; supplying information for at least one status of one or more components associated with the transmit signal based, at least in part, on the analysis; and automatically squelching the transmit signal if the at least one status is associated with excess output power of the transmit signal.
