4 Abstract Test Method
The remote test method is applied for this ATS.
A Point of Control and Observation (PCO) resides at the service access point between layers 2 and 3 in the test system.
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.
A second "informal" PCO, called "O" (for Operator) is used to specify control but not observation concerning the IUT;
events at this PCO are never used to generate test case verdicts. Messages sent by the tester at this PCO explicitly
indicate to the operator actions which are to be performed on the SUT. This is regarded as a preferred alternative to the
use of the implicit send event.

6 ATS conventions
6.1 Version of TTCN used
The version of TTCN used is that defined in TR 101 101 [3].
6.2 Naming conventions
6.2.1 Declarations part
This subclause describes the naming conventions chosen for the elements of the ATS declarations part.
6.2.1.1 Simple type, ASN.1 type and structured type definitions
The test suite simple type, ASN.1 type and structured type identifiers are written in lowercase starting by an uppercase

6.2.1.8 PCO type declarations
The point of control and observation type identifiers consist of two or three capital letters.
6.2.1.9 PCO declarations
The point of control and observation identifiers consist of one capital letter.
6.2.1.10 Timer declarations
The timer names begin with the prefix "T_", followed by a string in lowercase or uppercase letters with each word in
the following string starting with an uppercase letter.
6.2.1.11 ASP type definitions
The ASP types are defined in uppercase letters.
6.2.1.12 PDU type definitions
The type of a PDU is given in uppercase letters, followed by the string "_PDU".
6.2.2 Constraints part
This subclause describes the naming conventions chosen for the elements of the ATS constraints part.
6.2.2.1 Structured type constraints
Structured type constraint identifiers begin with an uppercase letter followed by uppercase and lowercase letters. The
meaning of the identifier represents the contents of the structured type constraint.
6.2.2.2 ASN.1 type constraints
ASN.1 type constraint identifiers begin with an uppercase letter followed by uppercase and lowercase letters. The
meaning of the identifier represents the contents of the ASN.1 type constraint.
6.2.2.3 ASP constraints
ASP constraint identifiers begin with an uppercase letter followed by uppercase and lowercase letters. The meaning of
the identifier represents the contents of the ASP constraint.
6.2.2.4 PDU constraint
Constraint identifiers begin with the type of the PDU meaningfully abbreviated, written in uppercase.
As a suffix a string "_S" or "_R" is appended to indicate if the constraint is sent or received by the tester. This string is
followed by a number allowing to distinguish between different variations of sent or received PDUs.
In case the PDU constraints are specific to the CTM part of the DECT access to GSM part of the ATS the character "C"
respectively "G" immediately follows the undersore character.
6.2.3 Dynamic part
This subclause describes the naming conventions chosen for the elements of the ATS dynamic part.

6.2.3.1 Test case identifiers
The test case identifiers are built with a string of uppercase letters subdivided by underscore characters distinguishing
between the different groups and subgroups of which the test suite consists. The highest group level allows to make the
difference between the test cases according to "CTM" and those according to "DECT access to GSM", for which
prefixes "CTM" and "DG" are used. The lowest subgroup level divides "valid" and "invalid" test cases, represented by
the character "V" or "I" respectively. Within these subgroups the test case are given individual numbers.
EXAMPLES: CTM_…_…_V_01
DG_…_ …_I_02
This convention is the one applied to identify the test cases in the TSS&TP document.
6.2.3.2 Test step identifiers
The test step identifiers are built with a string of lowercase letters prefixed by a string of capital letters and joined by an
underscore character. The first string indicates the main function of the test step; e.g. PR for preamble, PO for
postamble, ST for a normal step, LTS for a local test step, and DEF for a default test step. The second string indicates
the meaning of the step.
EXAMPLES: PR_Name
PO_Name
ST_Name
LTS_Name
DEF_Name
6.3 Use of ASN.1
6.3.1 Situations where ASN.1 is used
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 specified in the base
standards in ASN.1.
The possibility to use TTCN and ASN.1 in combination is used, i.e. referring to an ASN.1 type from a TTCN type.
6.3.2 Specification of encoding rules
The data types therefore consist of non-ASN.1 and eventually ASN.1 parts, each of which has to be encoded as these
parts require. Consequently two different types of encoding rules are used in this test suite:
• direct Encoding: the data structures fully specified in the relevant protocol standards – in a form sometimes
called tabular - are mapped bitwise onto the transfer data stream;
• basic Encoding Rules defined in the ASN.1 standard.
Note that within BER, there are a number of variations for the encoding of lengths of fields. According to
EN 300 196-1 [1], an IUT should be able to interpret all length forms within BER for received PDUs. When sending
PDUs containing BER encoding, EN 300 196-1 [1] gives guidelines but makes no restrictions on the length forms
within BER which an IUT may apply. This ATS prescribes a BER encoding variation which requests that, if possible,
the short form of length enocding is being used in data being sent, and that the receiving end shall be capable of
decoding any length form.
In this particular ATS all ASN.1 type constraints which are of type "Component" are to be encoded using BER. In
circumstances where it is irrelevant received components are decoded as if they had been directly encoded, applying a
simplified data structure.

7 ATS to TP map
The identifiers used for the TPs are reused as test case names. Thus there is a straightforward one-to-one mapping.
8 PCTR conformance
A test laboratory, when requested by a client to produce a PCTR, is required, as specified in ISO/IEC 9646-5 [2], to
produce a PCTR conformant with the PCTR template given in annex B of ISO/IEC 9646-5 [2].
Furthermore, a test laboratory, offering testing for either ATS specification contained in annex C, when requested by a
client to produce a PCTR, is required to produce a PCTR conformant with the PCTR proforma contained in annex A.
A PCTR which conforms to this PCTR proforma specification shall preserve the content and ordering of the clauses
contained in annex A. Clause A.6 of the PCTR may contain additional columns. If included, these shall be placed to the
right of the existing columns. Text in italics may be retained by the test laboratory.
9 PIXIT conformance
A test realizer, producing an executable test suite for ATS specification contained in annex C, is required, as specified
in ISO/IEC 9646-4 [2], to produce an augmented partial PIXIT proforma conformant with this partial PIXIT proforma
specification.
An augmented partial PIXIT proforma which conforms to this partial PIXIT proforma specification shall, as a
minimum, have contents which are technically equivalent to annex B. The augmented partial PIXIT proforma may
contain additional questions that need to be answered in order to prepare the Means Of Testing (MOT) for a particular
IUT.
A test laboratory, offering testing for either ATS specification contained in annex C, is required, as specified in
ISO/IEC 9646-5 [2], to further augment the augmented partial PIXIT pro
