TALAN Telephone and Line Analyzer DPA7000

The DPA-7000 to is an instrument for analysis, detection of anomalies and location of possible sources of threat to telephone systems.

The TALAN^TM DPA-7000 is a professional system designed for inspecting telephone lines in order to detect and locate possible surveillance device, as well as to assess the security level. It is compatible with analogue, digital and VoIP phones alike.

Automated tests suite
Multiple automatic tests conducted by DPA-7000 TALAN^TM system allow to inspect phone lines for unauthorized surveillance. Due to the automatic switching matrix, all possible combinations are tested – e.g. an 8-wire cable means 28 pairs, every one of which is tested. The results are stored for possible further analysis.

Digital demodulation
Telephone and line analyzer allows to determine whether an inspected line is used to transfer audio signals. DPA-7000 TALAN^TM is capable of decoding approximately 80% of digital phone systems used worldwide.

Frequency domain reflectometer (FDR)
Possible presence of a security threat is determined by detecting phone line's impedance anomalies. It allows to conduct comparative analysis for multiple pairs of wires and to compare results with previously collected information.

Non-linear junction detection (NLJD)
DPA-7000 TALAN^TM detects all electronic devices connected to a specific inspected line. It allows for easy determination whether any unidentified – and potentially dangerous – devices are attached to the line.

Digital multimeter
Measures the basic electrical parameters of telephone lines, such as voltage, current, or resistance. The switching matrix allows to analyse all possible wire combinations, while clear display of results makes it possible to identify anomalies.

Audio amplifier with built-in oscilloscope
Voice band audio signal amplifier (20Hz – 20kHz, 80dB total gain). A DC bias generator allows to power attached electronics.

RF signal analysis and detection
Detailed spectrum analysis (frequency up to 85MHz) and time domain display (shows AM and FM modulation). Due to a broadband RF probe, it is possible to analyse RF energy up to 8GHz and depict its level over time, allowing to locate radio transmitters.

VoIP (voice-over internet protocol) phone analysis
Ability to test VoIP phones – so-called Internet utilising IP protocol. Telephone and line analyzer collects address data, MAC/IP addresses, header types and statistical data, providind the possibility to filter them according to user-defined settings. It is possible to connect the device to non-POE (Power Over Ethernet) 10/1000Mbps lines using an adapter. Collected information is stored on USB memory or a Compact Flash card.

Specialist software of the telephone and line analyzer
Included software allows for transparent display of collected data, as well as to analyse and export it, and to generate reports. DPA-7000 TALAN^TM also provides the possibility to compare multiple lines simultaneously and identify potential threats.
