The test suite was designed for point-to-point configurations only, and does not include point-to-multipoint configurations.
This conformance test suite is basedon the UNI Signalling Protocol as described in the ATM Forum User-Network Interface (UNI) Specification, Version 4.0 [1]. The Implementation Under Test (IUT) is the network side implementation of this protocol. The abstract test cases contained in this document are a comprehensive reflection of the indicated Technical Reference.
The test methodology is a “remote test method” as described in Reference [4]. It is possible that the entire test suite is not applicable for all IUTs. A test selection procedure must be performed to determine the applicability of a test to a particular IUT. Such selection shall be based on the Protocol Implementation Conformance Statement (PICS) and the Protocol Implementation eXtra Information for Testing (PIXIT).
The purpose of this test suite is to test that the IUT does not violate any of the protocol procedures ofUNI Signalling Protocol as described in the ATM Forum User-Network Interface (UNI) Specification, Version 4.0 [1]. The preferred use of this test suite is under conditions where the only messages that are sent across the interface are those in response to events in the test cases themselves. In order to allow for conditions where the IUT might send additional messages (e.g., STATUS), the test suite has been designed in such a way that the verdicts will not be affected by receipt of these messages.
