The ISSI & CSSI interface test solution from Valid8 enables conformance or load testing of these interfaces in the P25 public safety network.
Simulates RFSSs, consoles and mobile radios to test equipment on the ISSI & CSSI interfaces.
User commands can be fully automated using HTTP API. This includes performing all test control functions as well as collecting results and metrics.
The application’s subsystems can be edited directly in the browser using TDL or by using the graphical tools. The Message Workshop allows for creating of test scenarios directly from the hex stream of a remote capture, while the Graphical Editor (on the feature roadmap for 2019) will allow for creating customized call scenarios by dragging and dropping the call flow to meet your test needs.
