The Testing of BT’s Intelligent Peripheral using abstract test suites from ETSI

Abstract

This paper describes the practical use of ETSI test suites in the testing of an Intelligent Peripheral, which is the Intelligent Network node responsible for in-band speech processing — playing announcements and processing any in-band responses.Standardised test suites, which are increasingly available from ETSI, offer the potential to cut costs. This is achieved by reducing the need for expensive in-house test development whilst maintaining the testing quality through a set of approved tests which are independent of development.This paper uses the experiences of testing the Intelligent Peripheral to examine whether these advantages are realised in practice. It describes the test suites, their test coverage, the modifications needed for test execution and the test results and metrics for the testing cycle.
