The purpose of this document is to define procedures for testing the interoperability of
subscribers/repeaters between different manufacturers, different models of the same
manufacturer, and different firmware upgrades of the same model. This is the first of a
series of documents, all of which discuss procedures for interoperability testing of
TIAI 02 digital radio equipment. The contents of this document are confined to
conventional voice systems. As currently envisioned, other documents in the series will
address capabilities of over-the-air rekeying (OTAR), trunking, data transmissions, and
networking. A prerequisite for interoperability testing is the requirement that the unit
under test (UUT) meet the conditions of conformance and performance as designated
in the TIAI 02 standards.
