Valid8 Approved by DHS P25 CAP for ISSI/CSSI Testing

WAKEFIELD, Mass. – April 5, 2023:, Inc., a leading provider of test and analytics solutions for next-generation devices and networks, today announced its test tool has been approved by the DHS Project 25 Compliance Assessment Program (P25 CAP) for verifying Inter-RF Subsystem Interface (ISSI) and Console Subsystem Interface (CSSI) conformance testing.

ISSI and CSSI are key interfaces that ensure first responders can communicate reliably across the myriad of now available devices.  This ensures seamless interaction between dispatchers, first responders, and support staff, each of whom may be using portable radios, laptops, dispatch consoles or some other technology.

“We are excited that our tests have been approved by the P25 CAP,” said Ian Carpenter, President of Valid8. “We see our platform as an important component in the journey to develop and evolve standards for device manufacturers in the public safety space."

Valid8's broad testing capabilities can be used across the breadth of the product lifecycle, from education to development, to pre-certification and final certification.  Equipment companies benefit from Valid8’s tool as a mechanism to develop new P25 ISSI/.CSSI interfaces & features in their products, and for pre-conformance testing before going to an accredited lab for certification.  Compliance labs also benefit from the Valid8 technology to perform certification testing as an approved tool.

ISSI/CSSI conformance is an important part of a broader testing program. A comprehensive testing platform that includes a battery of tests for conformance to standards, functional testing, and more can help a manufacturer not only prove compliance but leverage a comprehensive testing philosophy as a competitive advantage.

Ian Carpenter, along with other industry experts, discussed the topic in a panel session during this week’s International Wireless Communications Expo (IWCE) highlighting New Technologies for P25 Testing and Compliance.
