P25 ISSI and CSSI interface test solution

Overview

The ISSI & CSSI interface test solution from Valid8 enables conformance or load testing of these interfaces in the P25 public safety network.

What It Can Do For You

Simulates RFSSs, consoles and mobile radios to test equipment on the ISSI & CSSI interfaces.

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 andother equipment
  • Stateful modeling provides accurate emulation of networkelements

Features

  • Tests RFSSs
  • Measure Key Performance Indicators (KPIs) such as number of simultaneous sessions and Busy Hour Call Attempts (BHCA)
  • Check power-on, registration, and PTT voice calls
  • Registration load
  • SG and SU call load
  • RTP PTT IMBE/AMBE media file playback
  • Report on media received, call connect time, call duration, jitter, packet loss
  • Generate valid and invalid/negative messages and call-scenarios
  • Supports sending invalid responses including malformed, dropped and misordered packets
  • Alerts and notifications
  • Check parameters in messages from SUT and flag errors

Subsystems

  • RFSS
  • Dispatch Console
  • ISSI Gateway
KPIs
  • Call Attempts
  • Call Successes
  • Call Failures
  • Registration Attempts
  • Registration Successes
  • Registration Failures
  • 3xx Failures
  • 4xx Failures
  • 5xx Failures
  • Call setup time

Automation API

User commands can be fully automated using HTTP API. This includes performing all test control functions as well as collecting results and metrics.

Scripting

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 allows for creating customized call scenarios by dragging and dropping the call flow to meet your test needs.

Use Cases

RFSS Under Test

For testing the RFSS, the Valid8 Tester can generate SIP PTT calls on ISSI or CSSI to test performance and stability.

Supported Scenarios:
  • REGISTER
  • INVITE SU calls
  • INVITE SU calls
