Wednesday, November 01, 2017 | Comments

The Project 25 Technology Interest Group (PTIG) released a Project 25 (P25) standards update from the TIA TR-8 October meetings in San Diego.

Several additions to the trunking control channel messages standard were approved for publication. One addendum introduced a “vehicle sensed emergency” flag to the emergency alarm message, and another addendum introduced an “accessory sensed emergency” flag to the emergency alarm message.

In addition, an addendum to the Inter RF Subsystem Interface (ISSI) Messages and Procedures for Supplementary Data was approved for ballot. This addendum introduces the messages and procedures for individual regrouping control across an ISSI/Console Subsystem Interface (CSSI).

A revision of the Location Services Overview bulletin was approved for publication. This revision aligns the content of the overview document with the content of the Tier 1 and Tier 2 location service specifications.

A revision to the conventional interoperability test standard is in progress. The revision corrects editorial errors and makes clarifications on various test procedures but does not add, remove or technically alter tests.

PTIG is a group of individuals and organizations that share the mutual interest of advancing P25 standards. The full report is here.
