1 Scope
The present document specifies the Test Suite Structure and Test Purposes (TSS&TP) for the H225.0 protocol for
Terminal, Gatekeeper and Gateway.
The objective of the present document is to provide conformance tests that give a greater probability of
inter-operability. The TSS&TP specification covers the procedures described in ITU-T Recommendation H.323 [2] and
ITU-T Recommendation H.225.0 [3] as specified in TS 101 883 [1].
NOTE: The present document may not cover all requirements of the current version of TS 101 883 [1], as that
mapping document has not yet reached a sufficiently stable state. Further versions of this TSS&TP
specification will follow TS 101 883 [1] completely and cover all its requirements.
The ISO standard for the methodology of conformance testing (ISO/IEC 9646-1 [6], ISO/IEC 9646-2 [7] and
ISO/IEC 9646-3 [8]) is used as basis for the test methodology.

The items to be tested can be one of the following: Terminal, Gatekeeper, Gateway or Destination Gatekeeper. They are
a part of a Packet Based Network using a LAN with TCP/IP (see figure 1).

Figure 1: network architecture
The Implementation Under Test (IUT, see ISO/IEC 9646-1 [6]) for which this Test purpose specification applies
consists of the H.225.0 terminal to gatekeeper signalling (RAS) and the H.225.0 call signalling (BCC) (see figure 2).

4.2 Test Suite Structure (TSS)
The Test Suite Structure follows the network architecture and the protocol architecture. The first level is divided into
2 groups according to the protocol: RAS and BCC.
For the RAS protocol, each process is included in a corresponding sub-group: Gatekeeper Discovery Request (GDR),
Registration (REG), Administration (ADM), LOC (Location), BND (Bandwidth), URG (Unregistration), DRG
(Disengage) and Status (STA).
For BBC, 2 call phases are considered: phase A and phase E, each one forming a sub-group of BCC.
Finally each group is divided in 3 subgroups:
• V containing the valid test purposes;
• I containing the inopportune test purposes;
• S containing the invalid test purposes.

5.1.2 State Definitions
5.1.2.1 State definition for BCC
For the BCC protocol, the call states of ITU-T Recommendation Q.931 [5] for the user side are followed.
5.1.3 TP structure
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. A particular structure has been used and this is illustrated in table 2. This table should be
read in conjunction with any TP, i.e. use a TP as an example to fully understand the table.

5.1.4 Test strategy
As the base standard ITU-T Recommendation H.225.0 [3] contains no explicit requirements for testing, the TPs were
generated as a result of an analysis of the base standard and the corresponding PICS proforma.
The TPs are only based on conformance requirements related to the externally observable behaviour of the IUT, over
the TCP or UDP interface, and are limited to conceivable situations to which a real implementation is likely to be faced.
As indicated by the existence of the part 3 of this multi-part standard [9] (see foreword), the intention is to derive the
test purposes to an abstract test suite in TTCN. Consequently the test purposes are written in a manner, which fit the
TTCN methodology, and will consist of the textual documentation of the test cases.
5.2 TPs for H.225
All PICS items referred to in this clause are as specified in TS 101 804-1 [4].
Unless specified otherwise, the messages indicated are valid and contain at least the mandatory parameters and possibly
optional parameters.
