The test suite was designed for point-to-point configurations only, and does not include point-to-multipoint configurations. This ATS for the Network Side conforms only to sections 5.5 to 5.5.5.2 (Call/Connection Control Procedures for ATM Point-to-Point Calls). This test suite does not cover section 5.8 (Address Registration) or (Signalling ATM Adaptation Layer (SAAL)).
Tests for the user side of the UNI Signalling specification and for the Signalling ATM Adaptation Layer (SAAL) are contained in a separate documents.
This conformance test suite is basedon the UNI Signalling Protocol as described in the ATM Forum User-Network Interface (UNI) Specification, Version 3.1 [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).
This abstract test suite uses two Adaptation Layer (SSCF/SSCOP) links, one of which acts as the main tester’s line over which test events are sent and received, the other acts as a remote line. 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 3.1 [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.
