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 01, within each group. Groups are organized according to the TSS. Additional references
are added to identify the actual test suite (see table 1).
Table 1: TP identifier naming convention scheme
Identifier: __
= service + type of IUT: "NEGN" for connection NEGotiation, IUT = Network
= group number: two character field representing the group reference
according to TSS
= sequential number: (01-99)
5.1.2 Source of TP definition
The TPs are based on EN 301 067-1 [1].
5.1.3 Test strategy
As the base standard EN 301 067-1 [1] contains no explicit requirements for testing, the TPs were generated as a result
of an analysis of the base standard and the PICS specification EN 301 067-2 [2].
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 [6]).
5.1.4 Test of call states
Many TPs include a reference to the IUT's final call state after the realization of the TP. In these cases the TP includes
the requirement to ensure that the IUT has entered this particular final call state. Ensuring that the IUT is in a particular
call state shall be realized by following the procedures described in subclause 5.6.11 of EN 300 443-1 [7]. According to
these procedures, the IUT on receipt of a STATUS ENQUIRY message, shall respond with a STATUS message
indicating, in the fifth octet of the Call state information element, the current call state of the IUT. This exchange of
messages is not mentioned explicitly in each TP but is considered to be implicit in the reference to the final call state.
This way of phrasing the TPs has been used to avoid over-complicating the text and structure of the TPs and to improve
the readability.

5.2 TPs for the traffic parameters negotiation, network
All PICS items referred to in this subclause are as specified in EN 301 067-2 [2] unless indicated otherwise by another
numbered reference.
Unless specified:
- 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.

Ensure that the IUT in N0, on receipt of a SETUP message, with both alternative ATM traffic descriptor information
element, and minimum acceptable ATM traffic descriptor information element included,
- sends a RELEASE COMPLETE message with a cause information element indicating a cause value 73
"unsupported combination of traffic parameters" and remains in N0.
NEGN_01_02
Ensure that the IUT in N0, on receipt of a SETUP message, with the alternative ATM traffic descriptor information
element (with not allowed combination of traffic parameters),
- processes the message as valid, optionally sends a STATUS message with a Cause information element
indicating a cause value 100 "invalid information element contents" and enters N1.

Ensure that the IUT in N0, on receipt of a SETUP message, with the minimum acceptable ATM traffic descriptor
information element (with not allowed combination of traffic parameters),
- processes the message as valid, optionally send a STATUS message with a Cause information element indicating
a cause value 100 "invalid information element contents" and enters N1.
