TIA TSB-102.CBBH-A:2015

This Bulletin identifies the tests appropriate for consideration
by the P25 Compliance Assessment Program Governance Board for
Compliance Assessment testing in the area of Performance of a
Trunked Mode Fixed Station and related Infrastructure. These tests
were deemed appropriate by the industry and user members
participating in the work of the Compliance Assessment Process and
Procedures Task Group (CAPPTG). The CAPPTG includes TIA members and
representatives of Federal, State and Local Public Safety agencies
and organizations. This group, being familiar with the relevant
published standards, available P25 equipment and test equipment and
the general intentions of the P25 Compliance Assessment Program,
reviewed all tests and performance recommendations described in
references [1] and [2].

The P25 Compliance Assessment Program confirms that the
equipment of different manufacturers will interoperate with respect
to the P25 defined features, services and interfaces. P25
Compliance Assessment testing of the Common Air Interface is
expected to eventually include;

• Performance Tests ensuring the Common Air Interface endpoints
  are legitimate P25 devices for Trunking mode operation,
  Conventional mode operation, or both.
• Conformance Tests ensuring the Common Air Interface endpoints
  exchange the proper messages under the proper circumstances for
  Trunking mode operation, Conventional mode operation, or both.
• Interoperability Tests ensuring that Common Air Interface
  endpoints from different manufacturers do functionally interoperate
  for Trunking mode operation, Conventional mode operation, or
  both.

In determining the tests appropriate for P25 Compliance
Assessment Program testing in this area, the group considered
whether tests in references [1] and [2] were important for
achieving interoperability between equipment of different
manufacturers versus tests important for product design and/or
certification. In general, tests that were determined to be more
oriented towards product design and/or certification were deemed
unnecessary for inclusion in this list. The resulting list
therefore represents tests that are most important for or most
likely to impact interoperability between manufacturers building to
the same set of published standard documents.
