NetScout OneTouch AT Network Assistant

The OneTouch AT network assistant is an automated network troubleshooting tool that empowers IT professional teams to effectively validate, and troubleshoot Ethernet and Wi-Fi access networks


NetScout OneTouch AT Network Assistant


  • All-in-one: a network troubleshooting tool combining infrastructure, network service and end-to-end path performance test in one tool
  • Versatile: The OneTouch AT has a modular design: select the G2 module that has dual 10/100/1G copper/fiber optic Ethernet test ports and 802.11a/b/g/n/ac Wi-Fi radio, or the 10G module that has 100M/1/10G copper and fiber Ethernet test ports
  • Standardize: Network engineers can pre-program AutoTest profiles for field technician that automatically run a suite of tests with the press of a button, enabling identification of the most common problems in about a minute
  • VoIP ready: the G2 Module troubleshoots desktop SIP/SCCP based VoIP problems in real-time with inline call monitoring, logging, and scoring
  • Centralized Management: the cloud portal offer visibility to all of test results and project progress from any NETSCOUT handheld network troubleshooting tools: LinkSprinter, LinkRunner AT, AirCheck G2 and OneTouch AT


The OneTouch AT reduces the time network technicians spend validating and troubleshooting network performance problems. It provides all-in-one testing for Ethernet, Wi-Fi, network service and application performance. Multiple AutoTest profiles can be pre-defined by engineers so that field technicians can quickly validate a complete set of key parameters from the end user’s perspective and follow standardize troubleshooting procedures.
