A system is provided for intercepting signals transmitted between a target served by a fiber optic network and a subscriber. A network is described having a phone switch at a central office configured to receive signals for transmission to and from a target, such as the target of a criminal investigation. A signal received at the central office is assigned to an analog circuit, and a monitoring device configured to intercept and monitor the signal is installed along the analog circuit at a location that allows the monitoring of communications without notifying the target that he is under surveillance. After the signal has been monitored, it is converted to a digital signal for transmission. A method is also provided for intercepting a signal transmitted between the target served by a fiber optic network and a subscriber, such that a monitoring device may be installed without alerting the target.

System for intercepting signals to be transmitted over a fiber optic network and associated method

A device may include a communication interface to communicate with an optical line terminal and a processor. The processor may set an optical path from the optical line terminal to an optical network terminal, the optical path including one or more optical network elements. In addition, the processor may obtain, from the optical line terminal, a status reading of the optical network terminal when the optical path is set. Further, the processor may obtain, from the optical line terminal, a power reading at the optical network terminal when the optical path is set. The processor may record the status reading and the power reading.
