TALAN 3.0 Telephone and Line Analyzer

Detect Wire Taps and Eavesdropping

The TALAN 3.0 Telephone and Line Analyzer represents advanced capability to detect and locate illicit tampering and security vulnerabilities on digital, analog, and VoIP telephone systems. New hardware provides the ability to test twisted pairs against modern telecommunication threats including shield and ground.

Efficiency: compares the results of multiple tests on multiple phone lines to quickly identify threatening anomalies

Usability: combines several countermeasure testing capabilities into a single piece of equipment (voltage, current, resistance, capacitance, non-linear junction detection, frequency domain reflectometry, and digital demodulation technology)

Portability: weighs only six pounds and data can be exported for further analysis and reporting

Older model TALANs can be converted to TALAN 3.0 but will require hardware changes. Contact REI for a quote.

TALAN Data Viewer logo

The TALAN Data Viewer Software is a separate PC application that provides the ability to organize, analyze saved test sequence data and charts for report writing. Moreover, the TALAN Data Viewer software provides the ability to compare multiple phones/targets on the same chart allowing the user to quickly identify any anomalies compared to other phones tested. TALAN Data Viewer Software is compatible with Windows 2000 or later operating systems (including Windows 7). After installing TALAN Data Viewer Software, .TAL files generated on the TALAN, can be saved to the Compact Flash Card or a USB device, and then transferred to a PC where files can then be accessed by the TALAN Data Viewer Software.

  • Organize data for report writing
  • Compare test results from multiple targets in the same view
  • Export data and chart graphics
  • Preplan test sequence targets and location files
