1 Scope
This fourth part of EN 301 060 is applicable to the Basic call control extensions at the "b" service entry point for VPN
applications for the pan-European Integrated Services Digital Network (ISDN) as provided by European public
telecommunications operators at the T reference point (as defined in ITU-T Recommendation I.411 [11]) by means of the
Digital Subscriber Signalling System No. one (DSS1) protocol. Stage three identifies the protocol procedures and
switching functions needed to support a telecommunications service (see ITU-T Recommendation I.130 [10]).
The present document 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 of
implementation conforming to EN 301 060-1 [6] in compliance with the relevant requirements and in accordance with the
relevant guidance given in ISO/IEC 9646.

the implicit send event

4 Abstract Test Method (ATM)
The Remote test method is applied for the basic call 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.

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.
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.

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.
