1 Scope
The present document specifies the Test Suite Structure and Test Purposes (TSS&TP) for the Cordless Terminal
Incoming Call Additional Network Feature (ANF-CTMI) of the Interexchange signalling protocol for Private Integrated
Services Networks (PISN).
The objective of the present document is to provide conformance tests, which give a greater probability of
inter-operability. The TSS&TPs specification covers the procedures described in ETS 300 696 [5].
The ISO standard for the methodology of conformance testing (ISO/IEC 9646-1 [7], ISO/IEC 9646-2 [8] and
ISO/IEC 9646-3 [9]) is used as basis for the test methodology.
The TSS&TPs specification standard is applicable for the support of the Cordless Terminal Incoming Call Additional
Network Feature (ANF-CTMI) at the Q-reference point between Private Integrated Services Network Exchanges
(PINXs) connected together within a PISN. The Test Suite Structure and Test Purposes specified in the present
document are only intended for VPN scenarios at the "b" service entry point.
The Q-reference point is defined in ETS 300 475-1 [16].

5 Test Purposes (TP)
5.1 Introduction
For each test requirement a TP is defined.
5.1.1 TP naming convention
TPs are numbered, starting at 001, within each group. Groups are organized according to the TSS. Additional references
are added to identify the actual test suite and whether it applies to the network or the user (see table 1).
Table 1: TP identifier naming convention scheme
Identifier: __
= supplementary service: "CTMI"
= group up to 8 digit field representing group reference according to TSS
= sequential number (001-999)
5.1.2 Source of TP definition
The TPs are based on ETS 300 696 [5].
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.

NOTE 1: In order to use the same structure as for test group selection, the selection criteria is indicated at the
bottom of the test purpose.
NOTE 2: Unless specified the messages are valid and contain at least the mandatory information elements and
possibly optional information elements, the information elements are valid and contain at least the
mandatory parameters and possibly optional parameters.
5.1.4 Test strategy
As the base standard ETS 300 696 [5] 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, and are
limited to conceivable situations to which a real implementation is likely to be faced (ETS 300 406 [14]).
All the test purposes are mandatory unless they have a selection criteria. Optional test purposes (with selection criteria),
are applicable according to the configuration options of the IUT. The configuration option shall be covered by a PICS
item.
5.2 TPs for ANF-CTMI
All PICS items referred to in this subclause are as specified in ETS 300 696 [5] unless indicated otherwise by another
numbered reference.
Unless specified:
- Only the requirements from the point of view of the VPN "b" service entry point are considered. This implies
that the interactions with other networks are out of scope of the present document and causes that the
corresponding Test Purposes are not included in the present document.
- The messages indicated are valid and contain at least the mandatory information elements and possibly optional
information elements.
- The information elements indicated are valid and contain at least the mandatory parameters and possibly optional
parameters.

11 ETSI EN 301 455-1 V1.1.4 (2000-09)
The following wording convention was defined to make the test purposes more readable:
- When a message is to be sent or received on a call independent signalling connection, the message name shall be
followed by a '(sc)', e.g. CONNECT (sc) means that the CONNECT message is conveyed on a call independent
signalling connection.
- All the test purposes are valid for both user and network side of the VPN b interface. In order to simplify the text
and to make the test purposes more readable, only the User side Call states (Ux) are indicated in the test
purposes. For the network side of the VPNb interface, the mapping table below indicates which network call
state (Ny) corresponds to the user call state used in the test purpose. Equivalent call state means there that the
same message flow applies from the IUT point of view (e.g.: IUT sends a SETUP message gives the call state
U01 or N06).
User side call state equivalent network
side call state
U00 N00
U01 N06
U10 N10
EXAMPLE:
Ensure that the IUT in the call state U01 …
is equivalent to the following network side test purpose:
Ensure that the IUT in the call state N06 …
