P25 ISSI CSSI Conformance

Valid8's P25 ISSI CSSI Protocol Conformance Test Suites provide a convenient method to test the dispatch console and the RFSS on the ISSI and CSSI interfaces according to the TIA and CAP standards.


The Valid8 Conformance Test Suites are suitable for testing many protocols and interfaces in the wireless and wireline network including S1AP, X2AP, F1AP, Diameter, HTTP2, PFCP, GTP, SIP, P25, ISUP, H.323 and many others.

What It Can Do For You

The Conformance solution is capable of simulating and testing several devices individually or in parallel.

It can simulate

  • RFSS
  • Console

It can test

  • RFSS
  • Console

Why It’s Different

  • Scalable software-based architecture can run on a range of hardware from COTS and high-end customer provided hardware to Virtual Machines and the Cloud (e.g. Amazon AWS) for maximum versatility and performance
  • Web-based UI is easy to learn
  • HTTP API enable integration with automation test systems and other equipment
  • Stateful modeling provides accurate emulation of network elements


  • Pre-made test scenarios and procedures
  • PASS / FAIL analysis, including plain English diagnostic reason
  • Valid / Invalid testing
  • Customizable scenario code
  • User-configurable proprietary messages, IEs, headers
  • Animated test results action-replay
  • Easy to configure
  • Automatic execution of test batches
  • UDP, TCP, SCTP transport layer IPv4/IPv6 support
  • Suitable for development and QA test lab environments, verifying protocol compliance, negative and robustness testing, Regression testing and reproducing customer issues in the field


  • Verdict Pass/Fail/Inconclusive 
  • Reason information
Configurable Parameters
  • DUT IP Address
  • DUT System ID
  • DUT Group ID
  • DUT Unit ID
  • DUT Subscriber Unit
  • Valid8 Tester IP Address
  • Valid8 Tester WACN ID
  • Valid8 Tester System ID
  • Valid8 Tester RFSS ID
  • Valid8 Tester Group ID
  • Valid8 Tester Unit ID
  • Valid8 Tester Subscriber Unit

Automation API

User commands can be fully automated using REST API. This includes performing all test control functions as well as collecting results and metrics. It can be integrated into virtually any CI system via the HTTP API, including Jenkins, CircleCI, Gitlab and others.


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 1Q 2020) will allow for creating customized call scenarios by dragging and dropping the call flow to meet your test needs.
