Spectra Release 5.2 software adds the ability to emulate, test, generate, and evaluate networks and network elements that support the SS7 SCCP User Adaptation Layer (SUA) running over Steam Control Transmission Protocol (SCTP). Running on the Spectra network diagnostic tool, the SUA tester application generates SS7 SCCP and TCAP signaling traffic to stress test application server processes (ASPs) and signaling gateways (SGs). It also performs functional and conformance testing for ASPs, SGs, and application servers, as well as evaluates SUA protocol performance across SGs, ASPs, and application servers.
