Overview

In the P25 network, the Inter RF Subsystem Interface (ISSI) is an open interface that enables RF Subsystems (RFSSs) from different vendors to communicate with each other.

The Valid8 P25 ISSI Load Tester enables testing of SIP and RTP IMBE on the ISSI G interface. The related conformance test suite is also available

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 IMBE 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
