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: __
= protocol specification: "GFP"
= type of IUT: U User
N Network
= group 2 digit field representing group reference according to TSS
= sequential number (001-999)
5.1.2 Source of TP definition
The TPs are based on EN 301 061-1 [2].
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.

the configuration option is covered by a Protocol Implementation Conformance Statement (PICS) item, a
selection criteria is indicated, else the selection of the corresponding test cases will depend on test suite
parameters Protocol Implementation eXtra Information for Testing (PIXIT) in the Abstract Test Suite
(ATS).
NOTE 2: Text in italics will not appear in TPs and text between <> is filled in for each TP and may differ from one
TP to the next.
5.1.4 Test strategy
As the base standard EN 301 061-1 [2] contains no explicit requirements for testing, the TPs were generated as a result
of an analysis of the base standard and the Protocol Implementation Conformance Statement (PICS) specification
EN 301 061-2 [3].
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 [4]).
5.2 Network TPs for VPN-GFP
All PICS items referred to in this subclause are as specified in EN 301 061-2 [3] unless indicated otherwise by another
numbered reference.
Unless specified, the messages and IEs indicated are valid and contain at least the mandatory parameters and possibly
optional parameters.
5.2.1 Common IE approach
Selection: IUT supports the common IE category. PICS: Mcn 1.
In all the TPs of this subclause, the call reference is to be considered in a Virtual Private Network (VPN) context.
The following TPs are testing the procedures associated with the transport of components using the messages for the
establishment and clearing of calls.
The primitives exchanged between the different entities are not observable. Only the PDU exchanged between peer
implementations can be observed.

10 EN 301 061-5 V1.1.3 (1998-10)
So to check that the component is properly transmitted to the Generic Functional Transport (GFT) entity, it shall
provoke a reaction from Remote Operations Service Element (ROSE) entity that will request the transmission of the
corresponding component as response. This component will be transmitted in a call related message with the same call
reference, which is observable.
To provoke a reaction from the ROSE entity, a return result component, with an invokeID not related to a currently
active invocation, can be sent.
5.2.1.1 Bearer related transport mechanism
Selection: IUT supports the bearer related transport mechanism. PICS: MCn 1.1.
In all the TPs of this subclause, the call reference is in a VPN context.
5.2.1.1.1 Protocol control

entity will be the addressed PINX and can treat the received component.
