SIGTRAN Protocol Test Suite comprises of SIGTRAN Protocol Analyzer, SIGTRAN Protocol Emulation over IP, SIGTRAN ISDN over IP Emulation, and BICC Protocol over IP Emulation. As VoIP testing tool, SIGTRAN protocol decoder software permits real-time analysis, call trace, capture, and filtering of SS7 and ISDN signaling messages over IP. MAPS™ SIGTRAN protocol simulator/tester covers SS7 simulation over IP Networks and can simulate ISUP signaling specification defined by ITU-T standards.
