P25 Load Tester

Simulates mobile radios & RFSS to test P25 equipment on ISSI & CSSI interfaces.

Overview

The Valid8 P25 tester enables testing of SIP, RTP with Floor Control. It includes test scenarios including Unit-to-Unit, Group, Emergency calls.

What It Can Do For You

Scalable P25 SIP, RTP load and feature testing.

Test P25 equipment and public safety networks with realistic traffic.

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

Features

  • Tests P25 RFSS and CSS
  • 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
  • RTP 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
  • Security testing
  • Alerts and notifications

Subsystems

The Valid8 P25 tester is comprised of multiple subsystems that are available individually or in parallel, and are scalable to fit your needs. The individual emulators are controllable through their call controllers, and the traffic can be captured through use of a remote capture tool such as Wireshark.

KPIs
  • Call Setup Time
  • Post Dial Delay
  • Post Pickup Delay
  • Call Teardown Time
  • Media Delay
  • PTT Access Time
  • End-to-end Access Time
  • Mouth-to-Ear latency
Configurable Parameters
  • ‍Call session length
  • Concurrent calls/endpoints
  • BHCA/CPS

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. Includes Autom8 Python framework.

Scripting

The application’s subsystems can be edited directly in the browser using TDL. The Message Workshop allows for the creation of test scenarios directly from the hex stream of a remote capture, while the Composer graphical editor (being deployed for all products in 2021) will allow for creating customized call scenarios by dragging and dropping the call flow to meet your test needs.
