SURVEILLANCE DATA RECORDING DEVICE AND METHOD
A surveillance data recording device includes a display, a digital tuner, and a control mechanism. The display displays a received surveillance data signal over a first bandwidth. The control mechanism allows a user to select a frequency band of interest. The digital tuner truncates the received signal to produce a narrowband signal comprised only of portions of the received signal that are within the frequency band of interest.A digital storage unit, such as a fixed or removable hard drive or solid state storage device, stores the narrowband signal over a period of time.
SYSTEM AND METHOD FOR MAPPING SS7 BEARER CHANNELS
A system and method for associating Signaling System 7 logical circuits and bearer channels are presented. The system may include an event detector configured to receive an SS7 signaling message on an SS7 signaling link, parse a logical circuit from the SS7 signaling message, receive an SS7 bearer channel, and detect a bearer channel event on the SS7 bearer channel. A statistical learning model block is configured to calculate a correlation confidence value between said bearer channel and said logical circuit. The method may include parsing a logical circuit ID from a signaling message on an SS7 signal link, identifying a bearer channel associated with a bearer event on a bearer circuit, and calculating a current correlation confidence value between the logical circuit ID and the bearer channel.
