GL Communications announced an Air Traffic Management (ATM) test suite to rigorously test Analog, TDM, Ethernet, and IP communications networks.

GL’s Timing Measurements its Air Traffic Management (TM-ATM) test suite to accurately emulate endpoints in ATM networks and provide critical timing measurements for various types of delay occurrences in signaling and voice transmission through the network. It includes all necessary hardware and software to identify, capture, timestamp, and correlate events at Analog, TDM, and IP interfaces.

Key Features include: Centralized control and test reporting; Ability to interface with Analog, TDM, and IP based systems; Measure delay and voice quality across Analog to/from IP, Analog to/from Analog, and IP to/from IP; Automated tests to run multiple iterations for accuracy and consistency; Timing accuracy using different clock sources – Local clock, GPS, Master, and Slave; GPS mode is suitable for field testing; Local/Master/Slave modes are suitable for Lab testing; Supports audio/tone transmission and recording; Outputs routable packets for field testing; Up to 32 hardware-based filters for wire-speed filtering; Each filter is 120 bytes User-defined Raw hex filter; Each filter works in trigger mode for filtering a single packet; Flexible filters for complex filtering; Supports Voice detection in IP packets and Voice Delay calculation; End to end voice quality using ITU-T standard algorithms (POLQA); Measured delays for every iteration are logged to a CSV file.
