GAO's PSTN network analyzers have the following functions:  

  •  Call Testing: GAO's PSTN network analyzers can initiate and receive phone calls to test the functionality and quality of the PSTN connections. They can emulate both caller and receiver endpoints, enabling comprehensive testing of call setup, voice quality, and call termination. 
  • Line Testing: Our PSTN network analyzers can perform line testing to assess the condition and quality of telephone lines. They measure parameters such as line voltage, loop resistance, line capacitance, line noise, and line impedance to identify any issues that may affect the quality or reliability of voice communication. 
  • Fault Detection and Diagnostics: Our PSTN network analyzers are equipped with diagnostic capabilities to identify and diagnose faults in telephone networks. They can detect issues such as line breaks, cross-talk, impedance mismatches, signal loss, and echo, allowing technicians to pinpoint the source of the problem for troubleshooting. 
  • Signal Analysis: GAO Tek's PSTN network analyzers can analyze and measure various aspects of voice signals in telephone networks. They can assess signal quality, including metrics like signal-to-noise ratio, total harmonic distortion, signal level, and frequency response. This helps in evaluating the clarity and integrity of voice communication. 
  • Jitter and Delay Measurement: GAO's PSTN network analyzers can measure jitter and delay in telephone networks. Jitter refers to variations in the timing of voice packets, while delay refers to the time it takes for a signal to traverse the network. These measurements help assess the quality and stability of real-time voice transmission. 

GAO Tek's PSTN network analyzers are rugged, versatile, and precision measurement instruments. They comply with applicable industry standards such as ITU-T, TIA/EIA, ETSI, ANSI, and IEEE.  

Our PSTN network analyzers help our customers comply with relevant U.S. government regulations such as:

Our PSTN network analyzers have the following applications:  

  • Line Testing and Fault Diagnosis: GAO's PSTN network analyzers are used to test and diagnose faults in telephone lines. They can detect issues such as line noise, signal loss, distortion, and other impairments that may affect call quality or connectivity. 
  • Quality of Service (QoS) Analysis: Our PSTN network analyzers help assess the quality of service provided by the telephone network. They measure parameters like voice clarity, delay, echo, and jitter to determine if the network is meeting the required standards for voice communication. 
  • Call Monitoring and Analysis: GAO Tek's PSTN network analyzers enable the monitoring and analysis of individual calls. They capture and analyze call signaling and media traffic to evaluate call setup times, call duration, call routing, and other call-related metrics. This information is useful for troubleshooting and optimizing call flows. 
  • Load Testing and Capacity Planning: Our PSTN network analyzers can simulate high call volumes to test the capacity and performance of the telephone network. Load testing helps determine if the network can handle peak call traffic without degrading call quality or experiencing congestion. 
  • Protocol Analysis: GAO's PSTN network analyzers support the analysis of signaling protocols used in PSTN, such as integrated services digital network or signaling system 7. They can capture and decode signaling messages to identify protocol errors, signaling failures, or compatibility issues.
