4 Abstract Test Method (ATM)
The remote test method is applied for the user ATS. The Point of Control and Observation (PCO) resides at the service
access point between layers 2 and 3. This PCO is named "L0" (for Lower). The L0 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 [8] 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 to TP map
The identifiers used for the TPs (see EN 301 003-3 [3]) are reused as test case names. Thus there is a straightforward
one-to-one mapping.
7 PCTR conformance
A test laboratory, when requested by a client to produce a PCTR, is required, as specified in ISO/IEC 9646-5 [11], to
produce a PCTR conformant with the PCTR template given in annex B of ISO/IEC 9646-5 [11].
Furthermore, a test laboratory, offering testing for the 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 of
the present document.
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.
8 PIXIT conformance
A test realizer, producing an executable test suite for the Abstract Test Suite (ATS) specification contained in annex C,
is required, as specified in ISO/IEC 9646-4 [10], 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
Implementation Under Test (IUT).
A test laboratory, offering testing for the ATS specification contained in annex C, is required, as specified in
ISO/IEC 9646-5 [11], to further augment the augmented partial PIXIT proforma to produce a PIXIT proforma
conformant with this partial PIXIT proforma specification.
