4 Introduction
Implementations Under Test (IUTs) which are to be tested using this ATS are required to have previously been tested
for conformity against and passed the test suite for EN 300 403-1 [8], and the ATS related to ETS 300 143 [1],
ETS 300 144 [2] and ETS 300 145 [3] which is contained in I-ETS 300 763-2 [10].
Any messages or fields within messages which are introduced by ETS 300 403-1 [8] are included in this ATS.
Behaviours in test cases have been described in such a way to be able to take into account ETS 300 403-1 [8] basic call
standard. This ATS also takes into account messages defined for the supplementary services, in particular
ETS 300 196-1 [4]. When such messages are received, they are ignored by the ATS as this is not within the scope of the
present document.
5 Abstract Test Method (ATM)
5.1 Description of ATM used
This ATS describes the testing specification of the protocol procedures and switching functions needed to support the
videotelephony, telephony 7 kHz, audiographic conference and videoconference teleservices at T or coincident S and T
reference points for the user.
Testing activity will take place on the D-channel and on one or two B-channels depending on which teleservice is
supported and where the service is provided. The videotelephony, audiographic conference and videoconference
teleservices can employ two or more B-channels and telephony 7 kHz teleservice up to one B-channel. Only S and T
reference point has an associated in-band protocol entity and has to follow requirements on B-channels.
As a consequence of testing multiple channels simultaneously, the concurrent testing method is used. A test
configuration includes at least a master test component for controlling co-ordination and D-channel activity and
eventually one or two PTCs for each involved B-channel. Each of the MTC and PTCs has got a Point of Control and
Observation (PCO). The remote test method as defined in ISO/IEC 9646-2 [12] is applied.

5.2 Conventions for test components and PCOs
Figure 1 shows a logical view of the complete configuration of the MTC, PTCs, and PCOs. The Co-ordination Point
(CP) relationships between the various components are also indicated. The test method used is very close to the test
method used in I-ETS 300 763-2 [10].

Figure 1: Multi-party test method
In a master/slave arrangement, the MTC is considered to be the master while the PTCs are the slaves.
There are communication paths or CPs between the MTC and each PTC (ie. CPDB1 and CPDB2). The MTC handles all
scheduling of test components and exchanges messages with PTCs to start or to s
