Talan 3.0 System for telephone line analysis and detection of analog and digital wiretaps in VoIP telephones system

TALAN is a professional tool which enables scanning of telephone systems - both analogue and digital, as well as VoIP systems for detecting and locating surveillance devices.

TALAN 3.0 is a modernised version of the well-known model TALAN DPA-7000. To be able to quickly identify unauthorised activity in the VoIP system, TALAN 3.0 intercepts and makes analysis of all network streams. It is able to detect quite quickly whether there are any packet data sent when the VoIP system is not in use.

The interface os TALAN 3.0, which is easy in use, enables the user to watch consistent patterns and repetitive activities. Common VoIP services often show a unique feature set which can lated be used for visual identification of similar activities. Wide advanced filters enable locating and identification of information.

What new in TALAN 3.0?

• traffic analysis in VoIP networks
• FFT algorithm visually displays VoIP traffic
• advanced input panel for testing and accepting Internet connections
• Earth/Ground testing by modified external wire connections

Key features of the wiretap detector TALAN 3.0

• 

  ANALYSING VoIP TELEPHONES

  The TALAN 3.0 is not only able to intercept but also to analyse unauthorised VoIP connections. All contact details, MAC/IP addresses, inquiries, statistics and old protocols which are normally skipped by other devices.

• 

  Packet of FFT automated tests

  FFT algorithm patented by the manufacturer converts the times of network traffic to frequency graphs. TALAN creates patters that are normally recognisable by most of devices and, additionally, it enables detection of real-time traffic in VoIP system. Test results can be stored for later analysis.

• 

  Digital multi-meter

  Interception detector TALAN 3.0 scans the key parameters of the telephone line such as the voltage, current and resistance and the switching matrix makes it possible to analyse all combinations of cables and represent it in an easy-to read overview.

• 

  DIGITAL DEMODULATION

  TALAN makes it possible to decode 80% of digital telephone systems. It also analyses the purpose of use of each line e.g. whether it is used for audio signal transmission.

• 

  Frequency Domain Reflectometry (FDR)

  The FDR method allows you to make a comparative analysis for many pairs of cables and to check the results against the earlier collected data. The probability of surveillance is determined on the basis of anomalies in the line impedance.

• 

  Non-linear junction detection (NLJD)

  This functions enables detection of all electronic appliances that are connected to the examined line. This method allows for a quick check whether there are any unidentified device connected to the specific line and whether it may pose a threat.

• 

  Audio amplifier with a built-in oscilloscope

  The TALAN 3.0 has been equipped with an amplifier which is to reinforce the signal in the acoustic band of 20 Hz - 20 kHz (total gain to 80dB). Power generator makes it possible to provide power to the phone line scanner.

• 

  RF SIGNALS ANALYSIS AND DETECTION

  Precise analysis of spectrum (bands up to 85 MHz) and time domain display to show the modulation for AM and FM signals. Wideband RF probe within the band up to 8 GHz makes it possible to analyse the energy and provides graphic presentation of the signal changing in time. This allows for tracking the suspected radio transmitter.

• 

  Harmonic Locator Probe (HLP)

  TALAN has been equipped with a harmonic locator probe (HLP) which is used for tracing wires in order to detect a source/ location of any type of electronics that might be used for eavesdropping.

• 

  Storing of analysis data

  The removable memory in the device makes it possible to archive all tests and measurements made for further deeper insight.

• 

  Software for TALAN 3.0

  PC software provides wide organisational possibilities. It significantly facilitates file management, making analysis reports as well as export of data. The software generates comparative graphs of many telephone lines simultaneously.
