“8 Suppliers Participate in P25 Trunked Interoperability Event

Eight manufacturers participated in a Project 25 (P25) trunked interoperability event held by Motorola Solutions the week of Aug. 24.

The P25 Compliance Assessment Program (CAP) test plan prescribed in the Trunked Interoperability requirements section of the current Compliance Assessment Bulletin (P25-CAB-CAI_TEST_REQ_CAB-March 2010) was used. The CAB traces directly to the TIA published Interoperability Testing for Voice Operation in Trunked Systems (TIA-102.CABC-A), and the Recommended Compliance Assessment Tests for Trunking Interoperability (TSB-102.CBBJ) documents.

Eight manufacturers participated in the event, testing one model class in one frequency band. For example, each manufacturer completed one set of the CAB trunked interoperability tests. Participants’ subscriber radios were programmed with information provided by Motorola Solutions in advance. Each participating company was required to bring at least one technical staff person with knowledge of its radio, the CAB and its related Telecommunications Industry Association (TIA) test documents.

Harris, Icom America, JVCKENWOOD, Midland, Relm Wireless, Simoco, Tait Communications and Technisonic also participated in the event.

Michael Schafer, president of independent testing laboratory Compliance Testing, led the testing. The team recorded each test result in the “test application,” an Excel file with two tabs: a vendor Information cover sheet identifying the test radios and vendor test pass criteria describing the expected hardware responses and display for each test. Each participant had to submit fully completed test application and test pass criteria by July 17 or they were disqualified from participation.

The Motorola team of system operation and administration experts, led by John Lambrou, Motorola Solutions P25 compliance, system standards, coordinated the system settings for each set of tests. The Motorola Solutions team, Compliance Testing team and the equipment manufacturer team all worked together to conduct each test and record the results.

“I found the Motorola Solutions team to be extremely professional with a strict attention to detail and adherence to the testing protocols,” said Chris Lougee, TIA Private Radio Section (PRS) chair and with Icom America. “I was impressed with the strict independence of Compliance Testing as the third-party accredited test organization. They took their role very seriously with strict discipline and adherence to the test plan.”

Compliance Testing will provide participants with a detailed test report of the results of the testing of their product to enable them to create their own suppliers’ declaration of compliance (SDoCs) and summary test reports. Any potential end users should expect P25 interoperability with Motorola Solutions ASTRO system Release 7.15 with GTR8000 base station.

“The testing process I observed this week was a testament to the collaborative efforts by industry, end users and government agencies,” Lougee said. Industry is clearly a stakeholder in the CAP. A continued sustained joint effort between CAP and the industry/end user representatives in TIA/P25 will be instrumental in the continued success of CAP.” This event was made possible by Motorola Solutions and Compliance Testing lab recognitions as defined and administered by CAP. CAP specified the guidance provided by the CAB from tests created and maintained by TIA and approved by the P25 Steering Committee. In 2013, DHS Science and Technology (S&T) announced that three accreditation boards (ABs) — American Association for Laboratory Accreditation (A2LA), ANSI-ASQ National Accreditation Board and International Accreditation New Zealand — were selected to re-accredit the eight laboratories that test P25 equipment to verify required standards are met. However, the re-accreditation has not yet begun. The prior accreditations are grandfathered by DHS until the new accreditation program begins.

Earlier this year, Compliance Testing requested funding from the Department of Homeland Security (DHS) to add two more trunked systems to its lab, providing a one-stop shop for interoperability testing.”
