1 Scope
This fourth part of EN 300 058 specifies the Abstract Test Suite (ATS) and partial Protocol Implementation eXtra
Information for Testing (PIXIT) proforma for the User side of the T reference point or coincident S and T reference
point (as defined in ITU-T Recommendation I.411 [10]) of implementations conforming to the stage three standard for
the Call Waiting (CW) supplementary service for the pan-European Integrated Services Digital Network (ISDN) by
means of the Digital Subscriber Signalling System No. one (DSS1) protocol, EN 300 058-1 [2].
EN 300 058-3 [4] specifies the Test Suite Structure and Test Purposes (TSS&TP) related to this ATS and partial PIXIT
proforma specification. Other parts specify the TSS&TP and the ATS and partial PIXIT proforma for the Network side
of the T reference point or coincident S and T reference point of implementations conforming to EN 300 058-1 [2].

4 Abstract Test Method (ATM)
The remote test method is applied for the CW user ATS. The Point of Control and Observation (PCO) resides at the
service access point between layers 2 and 3. This PCO is named "L" (for Lower). The L PCO is used to control and
observe the behaviour of the Implementation Under Test (IUT) and test case verdicts are assigned depending on the
behaviour observed at this PCO.

Figure 1: Remote test method
ISO/IEC 9646-2 [6] allows the informal expression of Test Co-ordination Procedures (TCP) between the System Under
Test (SUT) upper layer(s) and the Lower Tester (LT). In the ATS contained in annex C, TCP is achieved by use of a
second "informal" PCO, called "O" (for Operator). This PCO is used to specify control but not observation above the
IUT and consequently, events at this PCO are never used to generate test case verdicts. The use of this O PCO is
regarded as a preferred alternative to the use of the implicit send event, in that it allows the ATS to specify in a clear and
meaningful way what actions are required to be performed on the IUT.
5 Untestable test purposes
There are no untestable test purposes associated with this ATS.
6 ATS conventions
This clause is structured similarly to the structure of a TTCN ATS. However, the names of the subclauses are arranged
in a way more suitable to the present document.
6.1 Declarations part
6.1.1 Type definitions
6.1.1.1 Simple type definitions
Where appropriate, simple types have a length, a value list or a range restriction attached.
Simple types defined as being of some string type (e.g. BIT STRING, OCTET STRING), have a length restriction or a
value list attached.
Simple types, defined as being of INTEGER type, have a value list or a range restriction attached.

6.1.1.2 Structured type definitions
6.1.1.2.1 TTCN structured type definitions
All structured type definitions are provided with a full name.
All elements in every structured type definition, defined as being of some string type (e.g. BIT STRING,
OCTET STRING), have a length restriction attached.
If an element in a structured type definition is defined as being of a referenced type, the (possible) restriction is defined
in that referenced type.
For information elements the identifier, which is unique for each element, has its type defined as a simple type where the
value list is restricted to the single value which is the identifier itself. This has the advantage that it allows a test system
derived from this ATS to easily identify information elements embedded in messages. An ATS where information
element identifiers are represented as unrestricted types can present difficulties for a derived test system in the case
where it needs to find one information element embedded in a number of others and the constraints for the other
elements have the any-or-omit value. In such a case the test system cannot easily find the beginning of each information
element.
6.1.1.2.2 ASN.1 structured type definitions
There are no ASN.1 structured type definitions in the ATS.
6.1.1.3 ASP type definitions
6.1.1.3.1 TTCN ASP type definitions
TTCN ASP type definitions only contain one PDU or no PDU at all. The relationship between an ASP type and a PDU
type is one-to-one. That is, there exists one ASP type definition for each PDU type definition (if that ASP type contains
a PDU).
All TTCN ASP type definitions are provided with a full identifier.
Some ASPs are not parameterized as shown in the example in table 1. Such ASPs are only used for requesting or
receiving service from the lower layer.

There are no ASN.1 ASP type definitions in the ATS.

6.1.1.4.1 TTCN PDU type definitions
The TTCN PDU type reflects the actual data being transferred or received. All PDUs are embedded in ASPs.
If a specific PDU type definition contains elements defined in terms of a pre-defined type, that element has a restriction
attached to it.

There are no ASN.1 PDU type definitions in the ATS.
6.1.2 Test suite constants
No test suite constants are used or defined in this ATS.
6.1.3 Test suite parameters
Each test suite parameter is defined in terms of a predefined type or a referenced type. A referenced type is used when it
is necessary to attach restrictions to these type definitions (it is not allowed to include restrictions directly in the test
suite parameter table). The referenced type can have a length or value restriction attached to it in its declaration table.
