1 Scope
This fourth part of EN 300 130 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 [11]) of implementations conforming to the stage three standard for the
Malicious Call Identification (MCID) supplementary service for the pan-European Integrated Services Digital Network
(ISDN) by means of the Digital Subscriber Signalling System No. one (DSS1) protocol, EN 300 130-1 [2].
EN 300 130-3 [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 300 130-1 [2].

4 Abstract Test Method (ATM)
The remote test method is applied for the MCID 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 [7] 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
ASN.1 has been used for three major reasons. First, types defined in ASN.1 can model problems that "pure" TTCN
cannot. For instance, data structures modelling ordered or unordered sequences of data are preferably defined in ASN.1.
Second, ASN.1 provides a better restriction mechanism for type definitions by using sub-type definitions. Third, it is
necessary to use ASN.1 to reproduce the type definitions for remote operation components as specified in the base
standards.
The fact that ASN.1 provides a better restriction mechanism for type definitions is used for the purpose of achieving
type-compatibility.
In table 1, the ASN.1 type BIT7OR15 is defined as being of type BIT STRING with a size constraint attached to it. The
size is determined by the value of CR_LENGTH, a test suite parameter. It can have the value of either 7 or 15. The type
BIT7OR15 is used in the structured type CR, field cr_r allowing this type to represent a Basic Access or a Primary Rate
Access call reference. By using this type definition the field cr_r is always type compatible with values of type
BIT STRING (SIZE(7)) and BIT STRING (SIZE(15)). Another approach to solve this problem would be to define the
type BIT7OR15 as BIT STRING (SIZE(7 | 15)). This type has a small disadvantage compared with the previous one. It is
impossible, in run-time, to determine the actual length of any instance of this type.
Table 1: ASN.1 type definition BIT7OR15

Type Name : BIT7OR15
Comments :
Type Definition
BIT STRING(SIZE(CR_LENGTH))
Table 2 shows a typical use of ASN.1. The CHI element will have two different type definitions depending on whether it
represents basic or primary rate access. In TTCN, this needs to be defined as two different types. In ASN.1 this can be
done in one, the type being a choice of either BASIC_CHI or PRIMARY_CHI. These two types are then (locally) defined
in the same table.

PDU).
