1 Scope
The present document specifies the Test Suite Structure and Test Purposes (TSS&TP) for TIPHON profile for ITU-T
Recommendation H.245 [4], according to TS 101 883 [1].
The objective of this test specification is to provide a basis for conformance tests for TIPHON profile for ITU-T
Recommendation H.245 equipment giving a high probability of inter-operability between different manufacturer's
TIPHON profile for ITU-T Recommendation H.245 equipments.
This test specification covers the procedures described in TS 101 883 [1], ITU-T Recommendation H.323 [3] and
ITU-T Recommendation H.245 [4].
The ISO standard for the methodology of conformance testing (ISO/IEC 9646-1 [6] and ISO/IEC 9646-2 [7]) as well as
the ETSI rules for conformance testing (ETS 300 406 [5]) are used as a basis for the test methodology.

3.1 Definitions
For the purposes of the present document, the following terms and definitions apply:
• Terms defined in ITU-T Recommendation H.323 [3];
• Terms defined in ITU-T Recommendation H.245 [4];
• Terms defined in ISO/IEC 9646-1 [6] and in ISO/IEC 9646-2 [7].
Inopportune: specifies a test purpose covering a signalling procedure where an inopportune message (type of message
not expected in the IUT current state) is sent to the IUT
Syntactically invalid: specifies a test purpose covering a signalling procedure where a valid (expected in the current
status of the IUT) but not correctly encoded (unknown or incorrect parameter values) message is sent to the IUT, which
shall react correctly and eventually reject the message
Test purpose: non-formal test description, mainly using text. This test description can be used as the basis for a formal
test specification (e.g. Abstract Test Suite in TTCN)
NOTE: See ISO 9646-1 [6].
Valid: specifies a test purpose covering a signalling procedure where all the messages sent to or received, from the IUT,
are valid (expected in the current status of the IUT) and correctly encoded

Figure 1: TSS of TIPHON profile for H245
The test suite is structured as a tree with a first level defined as H.245 representing the protocol group: "TIPHON
profile for H245".
4.2 Test groups
The test groups are organized in three levels. The first level creates two protocol groups representing the role of the
IUT. The second level separates the selected role for the IUT in groups of procedures. The last level in each branch
contains one or more of the standard ISO subgroups BV, BI, BO.
4.2.1 Protocol groups
The protocol groups identify the two roles of the IUT: Originating Endpoint (OE also known as Outgoing), and
Terminating Endpoint (TE also known as incoming), as defined in ITU-T Recommendation H.245 [4].
4.2.1.1 Originating Endpoint (OE)
The Originating Endpoint protocol group is divided in six groups of procedures. The first group of procedures identifies
the Capability Exchange procedures. The second group of procedures identifies the Master Slave Determination
procedures. The third group of procedures distinguishes the Unidirectional Logical Channel Signalling procedures. The
fourth group of procedures distinguishes the Bi-directional Logical Channel Signalling procedures. The fifth group of
procedures distinguishes the Close Logical Channel procedures. The sixth and last group of procedures distinguishes
the Mode Request procedures.
4.2.1.2 Terminating Endpoint (TE)
The Terminating Endpoint protocol group is divided in six groups of procedures. The first group of procedures
identifies the Capability Exchange procedures. The second group of procedures identifies the Master Slave
Determination procedures. The third group of procedures distinguishes the Unidirectional Logical Channel Signalling
procedures. The fourth group of procedures distinguishes the Bi-directional Logical Channel Signalling procedures. The
fifth group of procedures distinguishes the Close Logical Channel procedures. The sixth and last group of procedures
distinguishes the Mode Request procedures.

4.2.2 Main test groups
The main test groups are the valid behaviour group, the invalid behaviour group and the inopportune behaviour group.
4.2.2.1 Valid Behaviour (BV) tests
This test sub group shall verify that the IUT reacts in conformity with the TS, after receipt or exchange of valid Protocol
Data Units (PDUs). Valid PDUs means that the exchange of messages and the content of the exchanged messages are
considered as valid.
4.2.2.2 Invalid Behaviour (BI) tests
This test sub group shall verify that the IUT reacts in conformity with the TS, after receipt of a syntactically invalid
PDU.
4.2.2.3 Inopportune Behaviour (BO) tests
This test sub group shall verify that the IUT reacts in conformity with the TS, after receipt of a syntactically correct
PDU not expected in the actual message exchange or state.
5 Test Purposes (TP)
5.1 Introduction
5.1.1 TP definition conventions
Each TP has been written in a manner, which is consistent with all other TPs. The intention of this is to make the TPs
more readable and checkable. The TPs are defined following particular rules as shown in table 1. This table should be
read in conjunction with any TP, i.e. use a TP as an example to fully understand the table.
