Compliance Testing Finishes Accreditation to Perform ISSI/CSSI Testing
Tuesday, December 01, 2020 | Comments

Compliance Testing of Mesa, Arizona, completed the American National Standards Institute (ANSI) National Accreditation Board (ANAB) and DHS Department of Homeland Security (DHS) Science and Technology Directorate’s (S&T) assessment process to add Project 25 (P25) Compliance Assessment Program (CAP) Inter-RF Sub-System Interface (ISSI) and Console Sub-System Interface (ISSI) equipment testing to its ISO/IEC 17025:2017 scope of accreditation.

“Equipment bench tests are valuable, but nothing beats actual interoperability testing in the eyes of the end user community,” said Compliance Testing President Michael Schafer. “They want to ensure radio systems they own, or may purchase, will actually interoperate properly with others during an emergency event.”

Compliance Testing offers “scalable” coordination of ISSI/CSSI interoperability testing test events to meet individual client needs.

“We can just show up and conduct the testing or provide complete outsourcing of test events, or anywhere in between,” said Chris Lougee, LMR industry business development manager for compliance testing.

Without the “Field Test” accreditation lab scope, ISSI testing would require two radio frequency subsystems (RFSS), connected via ISSI, in a single physical lab location. This could be difficult and expensive for manufacturers. Compliance Testing is accredited to send a test engineer to one location, connect to the supporting RFSS via virtual private network (VPN), and observe the SU responses via video hookup. This should make it much easier for manufacturers of both RFSS and consoles to test without travel and shipping.

“On-site testing is available with our accreditation,” said Compliance Testing Engineer Dale Reitsma. “We take our accreditation on the road, the host and supporting locations do not need to be accredited. ANAB has approved our use of video connections to observe and confirm the equipment responses at the supporting location.”

Some industry experts estimate that 20-25% of ISSIs purchased have never been deployed. These are sometimes referred to as “dangling ISSIs.” Compliance Testing can assist agencies in testing their systems and setting them up to work properly.

“One sherriff told me ‘I know it is working, but I don’t know if it is working correctly’,” Lougee added. “We can test installed systems in the field against the P25 CAP standard.”

Compliance Testing offers different test events for ISSI/CSSI interoperability testing including RFSS to RFSS, RFSS to console and console to RFSS.

“DHS S&T will post ISSI/CSSI equipment that has completed P25 CAP Interoperability testing on our web site,” said Sridhar Kowdley, P25 program manager, DHS S&T. “This is a useful tool, for agencies seeking to deploy P25CAP compliant systems.”
