GAO’s  E1 testers have the following functions: 

• E1 Line Testing: Our E1 testers allow us to conduct thorough testing of E1 communication lines. We can verify the connectivity, integrity, and quality of the E1 circuits, ensuring they meet the required standards. 
• Signal Generation: Our E1 testers enable us to generate E1 signals for testing purposes. We can easily generate different signal patterns, including unframed, framed, and multi-frame signals, to assess the performance and behavior of the E1 communication system. 
• Signal Measurement and Analysis: GAO's E1 testers provide precise measurement and analysis of various parameters of E1 signals. We can accurately measure signal level, frequency, error rate, signal-to-noise ratio, and other relevant metrics to evaluate the quality and performance of the E1 lines. 
• Error Detection and Analysis: OurE1 testers can detect and analyze errors in E1 communication links. It empowers us to identify errors such as CRC errors, frame errors, bit errors, and other types of anomalies that may affect the integrity of the E1 signals. 
• Clock Synchronization Testing: GAO Tek's E1 testers allow us to assess the clock synchronization between different E1 devices or systems. We can measure the clock accuracy, jitter, and synchronization status to ensure proper synchronization and timing alignment. 

GAO Tek’s E1 testers help our customers comply with relevant U.S. government regulations such as:   

• Federal Communications Commission (FCC) Regulations 
• National Institute of Standards and Technology (NIST) Guidelines 
• Telecommunications Industry Association (TIA) Standards 
• National Telecommunications and Information Administration (NTIA) Guidelines 
• Department of Defense (DoD) Regulations 

GAO Tek’s E1 testers help our clients in complying with relevant Canadian government regulations such as: 

• Innovation, Science, and Economic Development Canada (ISED) Regulations 
• Canadian Radio-television and Telecommunications Commission (CRTC) Guidelines 
• Industry Canada (IC) Standards 
• Canadian Centre for Cyber Security (CCCS) Guidelines 
• Public Safety Canada (PSC) Regulations 

GAO's E1 testers have the following applications: 

• E1 Line Testing: Our E1 testers enable us to perform thorough testing and verification of E1 communication lines, ensuring their connectivity, integrity, and quality. 
• Troubleshooting: GAO'Tek E1 testers identify and diagnose issues in E1 links, such as signal loss, noise, distortion, or synchronization problems. 
•  Maintenance and Quality Assurance: Our E1 testers are used in maintaining and assuring the performance and integrity of E1 networks through regular testing and quality assurance procedures. 
• Protocol Analysis: Our E1 testers offer advanced protocol analysis capabilities, allowing us to monitor and analyze protocol signals on E1 lines, detecting anomalies or errors.  

Our E1 testers can be shipped overnight within the continental U.S. and Canada and can be shipped globally.
