TALAN [ Telephone and Line Analyzer ]


Voice-over Internet Protocol (VoIP) phone systems present a new form of security risk to communications. With new enhancements built into the TALAN software interface, users can now test internet protocol (IP) packet traffic on VoIP phones and systems. VoIP data collected by the TALAN software includes Source and Destination Mac Addresses; header type; statistics - total packets; packet rate; peak rate and run time. Users can also define advanced filtering options. Data can be stored and exported to USB or Flash as data files for further analysis, sharing and reporting.

The TALAN Telephone and Line Analyzer provides a complete integrated suite of tools to analyze, inspect, and test digital telephone lines (and other wiring) for taps and other eavesdropping devices.

The TALAN incorporates several types of telephone line tests including common tests such as voltage, current, resistance, and capacitance tests, as well as NLJD, FDR Frequency Domain Reflectometry, and Digital Demodulation technology into a single piece of equipment. Additionally, the TALAN utilizes an automatic internal pair switching matrix to automatically perform tests on all pair combinations. The ability to perform several different tests allows the user to compare the results of multiple tests on multiple phone lines, quickly identifying any potentially threatening anomalies. 

The TALAN represents a breakthrough in telephone line testing. There currently is no other product available with the same capabilities

TALAN Data Viewer Software

TALAN Data Viewer

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


This latest TALAN update enhances previous revisions.
