Description / Abstract:

INTRODUCTION

The purpose of this standard is to define procedures for testing the interoperability of RFSSs operating in trunked FDMA voice mode or trunked TDMA voice mode. Each RFSS is interconnected using an ISSI to test the interoperability of RFSSs from different manufacturers, different model RFSSs from the same manufacturer, the same model RFSS from the same manufacturer, and different RFSS software versions.1

Existing tests specified in [102CABC] are aimed at assessment of Common Air Interface (CAI) interoperability between a subscriber unit (SU) and its associated FNE. The set of tests described in this document extend these tests to assess ISSI interoperability utilizing multiple SUs in wide area roaming situations where multiple RFSSs and G interfaces are involved. The participating RFSSs in these tests involve an FDMA control channel working in conjunction with either FDMA voice channels or TDMA voice channels or both. The approach taken in this standard is to extend the interoperability test procedures for voice operations in trunked systems described in [102CABC] from an FNE whose topology is undefined to an FNE composed of multiple RFSSs that are connected via G interfaces. From the viewpoint of the Subscriber Units, the FNE is treated as a network cloud. It is recommended that the Subscriber Units (SUs) and the RFSSs are tested for Interoperability using [102CABC] prior to running the end-to-end tests for multiple-RFSSs using the ISSI. Test Suites are provided for each feature. Each Test suite provides a description of the test, applicable RFSS role combinations, expected behavior, call configuration, initial conditions and post conditions. Test Cases for the Test Suites are then developed which track and extend the Test Cases in [102CABC].

This standard tests the interoperability of RFSSs in three basic ways: (1) ISSI interoperability testing of RFSSs from two different manufacturers, (2) ISSI interoperability testing of two different Types of RFSSs from the same manufacturer, and (3) ISSI interoperability testing of the same Types of RFSSs from the same manufacturer. When necessary, two identical RFSSs of each Type (a total of 4 RFSSs) may be used in order to test the configurations. If only one RFSS of each Type is available (for a total of two different RFSSs) then the RFSSs need to assume multiple roles in the tests. The test procedures in this document provide the test configurations and procedures for both cases. It is acceptable, and even recommended, to use test configurations consisting of a single ISSI between two RFSSs. This will result in the simplest test configurations and test result reporting.

1 The Interoperability Reference Model – ISSI (IRM-I) is an Interoperability test model consisting of multiple RFSSs and G interfaces between them for a Unit-to-Unit or Group Call. This is defined in 1.2 of this document and Annex A.
