Catapult Communications announces new graphical tools for 3G load testing
Catapult Communications has announced system level enhancements to its DCT2000 Test System. Users are now able to create their load test sequences, perform run-time control of their load applications and generate statistical reports using graphical tools. The new tools are protocol independent and support all of the protocols and variants currently available on the DCT2000. Users can create complex, multi-protocol load test sequences by ''dragging and dropping'' pre-designed blocks to construct their desired call flow. Later, during run-time, the user can easily define and change critical load test parameters in real-time. By using the new tools, users are able to dramatically reduce the time they need for developing comprehensive 3G, VoIP, and SS7 load tests. Catapult delivers test solutions for over 160 protocols and variants in the following network areas: 3G, VoIP, GPRS, SS7, Intelligent Network, ATM, V5, Digital Cellular and isdn. more
