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.

Testing optical networks

A mounting structure is disclosed in a test-bed installation in which vertically aligned first backboards are pivotally secured to a front side of one of the upright posts of a relay rack for movement between a closed position and open positions. Vertically aligned second backboards are secured to a rear side of both upright posts of the relay rack in opposed relationship with the first backboards. A pair of optical network terminals is mounted on an outer side of each of the backboards, and a pair of battery backup units is mounted on an inner side thereof. Thus when one of the first backboards is moved to an open position, access is provided to the pair of battery backup units mounted on the first backboard so moved and to the pair of battery backup units mounted on the opposing second backboard.
