Foreword
ISO (the International Organization for Standardization) and IEC (the lnter-
national Electrotechnical Commission) form the specialized System for
worldwide standardization. National bodies that are members of ISO or
IEC participate in the development of International Standards through
technical committees established by the respective organization to deal
with particular fields of technical activity. ISO and IEC technical commit-
tees collaborate in fields of mutual interest. Other international organiza-
tions, governmental and non-governmental, in liaison with ISO and IEC,
also take part in the work.
In the field of information technology, ISO and IEC have established a joint
technical committee, lSO/IEC JTC 1. In addition to developing International
Standards, lSO/IEC JTC 1 has created a Special Group on Functional
Standardization for the elaboration of International Standardized Profiles.
An International Standardized Profile is an internationally agreed,
harmonized document which identifies a Standard or group of Standards,
together with Options and Parameters, necessary to accomplish a function
or set of functions.
Draft International Standardized Profiles are circulated to national bodies
for voting. Publication as an International Standardized Profile requires ap-
proval by at least 75 % of the national bodies casting a vote.
International Standardized Profile lSO/IEC ISP 10608-1 was prepared with
the collaboration of
- OSI Asia-Oceania Workshop (AOW);
- European Workshop for Open Systems (EWOS);
- OSI Implementors Workshop (OIW).
lSO/IEC ISP 10608 consists of the following Parts, under the general title

fntroduction
This part of ISO/IEC ISP 10608 (international Standardized Profile) is defined within the context of Func-
tional Standardization, in accordance with the principles specified by ISO/TR 10000-1 :1990. The context of
Functional Standardization is one patt of the Overall field of Information Technology (IT) standardization ac-
tivities, covering base Standards, profiles, and registration mechanisms. A Profile defines a combination of
base Standards that collectively perform a specific weil-defined IT function. Profiles standardize the use of
Options and other variations in the base Standards, and provide a basis for the development of uniform, in-
ternationally recognized System tests.
One of the most important roles for an ISP is to serve as the basis for the development (by organizations
other than ISO and IEC) of intemationally recognized tests and test Centers. ISPs are produced not simply
to legitimize a particular choice of base Standards and Options, but to promote real System interoperability.
The development and widespread acceptance of tests based on this and other ISPs is crucial to the suc-
cessful realization of this goal.
ISO/lEC ISP 10608 consists of several Parts, of which this is Part 1. ISO/IEC 10608-1 specifies subnetwork-
type independent requirements for Group TA profiles. ISO/IEC 10608-2 specifies subnetwork-type depen-
dent requirements for Profile TA51. ISO/IEC ISP 10608-3 specifies subnetwork-type dependent require-
ments for Profile TA52* ISO/lEC ISP 10608-4 specifies subnetwork-type dependent requirements for Profile
TA53. ISO/IEC ISP 10608-5 specifies subnetwork-type dependent requirements for Profiles TA1 111 and
TA1121.

5 Subnetwork-type Independent Requirements
5.1 General
The requirements stated in this clause apply uniformly to all conforming end Systems, without regard to the
type of subnetworks to which those end Systems might be attached. Additional requirements apply to end
Systems according to the type of subnetworks to which they are attached; these requirements are specified
in subsequent park of ISO/IEC ISP 10608.
5.2 Transport Layer Requirements
This part of ISO/IEC ISP 10608 specifies Provision of the connection-mode Transport Service, as defined
in ISO 8072, using class 4 of the connection-mode Transport Protocol, as defined in ISO 8073 and ISO
8073/Add.2 which defines Operation of class 4 over the connectionless-mode Network Service.
Additional requirements are given in annex A and C which define the IPRL for the Transport protocol. Annex
B contains defect reports related to ISO/lEC 8073 along with the Statement of any consequential require-
ments for implernentors of these profiles.
5.2.1 Static conformance requirements
A conforming implementation shall
a) satisfy the conformance requirements as stated in clause 14 of ISO 8073.
b) support of the mandatory features for class 4 over CLNS as defined in ISO 8073 and ISO 8073/Add.2.
c) if it Claims to be capable of initiating TC establishment, be capable of demonstrating the sending of a
CR TPDU with
1) class 4 as the preferred class.
d) if it Claims to be capable of responding to TC establishment, be capable of demonstrating the accep-
tance of a CR TPDU with class 4 as the preferred class.
e) if it Claims to be capable of initiating TC establishment, be capable of
1) transmitting a Called TSAP-ID field in a CR TPDU,
2) when necessary, transmitting a Calling TSAP-ID field in a CR TPDU that tan convey any one of the
Transport Selectors implemented by the System.
f) if it Claims to be capable of responding to a TC establishment attempt, be capable of

ISO/IEC ISP 106084 :1992 (E)
1) transmitting a Calling TSAP-ID field in a CC TPDU,
2) when necessary, transmitting a Called TSAP-ID field in a CC TPDU that tan convey any one of the
Transport Selectors implemented by the System.
g) be capable of configuring the initial values of the following Parameters:
Tl Local retransmission time
N Maximum number of retransmissions
I Inactivity time
W Window time
h) if an implementation is operating any policy which delays the transmission of AK TPDUs, the maximum
amount of time by which a Single AK TPDU tan be delayed shall be indicated to the remote transport
entity using the acknowledge time Parameter.
5.2.2 Dynamit conformance requirements
a) TSAP-ID
The implementation shall support remote TSAP-ID Parameters of variable size up to and including 32 octets
using any encoding and any value.
Local T-selectors shall not exceed 32 octets in length.
On receipt of a CR TPDU the absence of a Calling or a Called TSAP-ID Parameter shall be treated as equiv-
alent to a Zero length Calling or Called TSAP-ID Parameter.
The absence of the CC Calling TSAP-ID Parameter on receipt indicates that the value of the CC Calling
TSAP-ID Parameter is equivalent to the value of the CR Calling TSAP-ID Parameter.
The absence of the CC Called TSAP-ID Parameter on receipt indicates that the value of the CC Called
TSAP-ID Parameter is equivalent to the value of the CR Called TSAP-ID Parameter.
Figure 1 summarizes the handling of Called and Calling TSAP-ID Parameters in CR and CC TPDUs.

b) Option selection on connection establishment
A conforming implementation shall implement the “non-use of checksum” function. It is recommended that
ISO/IEC ISP 1060&1:1992 (E)
the initiator proposes the non-use of checksum.
c) Invalid values in known Parameters
Known Parameters with invalid lengths in a CR or CC TPDU shall be handled as a protocol error.
Known Parameters with valid lengths but invalid values in a CR TPDU shall be handled as follows:
AGtiQn
Called TSAP-I D send DR TPDU.
Checksum discard CR TPDU.
5.3 Network Layer requirements
ISO/lEC ISP 10608 specifies Provision of the connectionless-mode Network Service, as defined by ISO
8348 and ISO 8348/Add.l, using the connectionless-mode Network Protocol as defined by ISO 8473.
ISO/IEC ISP 10608 specifies the use of OSI network addresses according to ISO 8348/Add.2. Any NSAP
address, in any of the formats identified by ISO 8348/Add.2, may be used with ISO 8473.
ISO/lEC ISP 10608 specifies the use of an ES-IS protocol for the exchange of routing information between
end Systems and intermediate Systems attached to the same subnetwork. Slnce the implementation of the
ES-IS protocol varies from subnetwork to subnetwork, reference to a specific base Standard will be found
in the subnetwork-type dependent Parts of ISO/IEC ISP 10608.
Additional requirements are given in Annex C which defines the IPRL for the Network Layer protocol.
5.3.1 CLNP requirements
5.3.1 .l Inactive subset
An implementation shall not transmit PDUs encoded using the inactive subset. Received PDUs encoded
using the inactive subset may be discarded.
5.3.1.2 Non-segmenting subset
An implementation shall not generate data PDUs without a Segmentation part. However, an implementation
shall receive and correctly process PDUs which do not contain the Segmentation part to provide interoper-
ability with those Systems that have Chosen to transmit PDUs without a Segmentation Part, i.e., the segmen-
tation permitted flag set to Zero.
5.3.2 ES-B requirements
Additional subnetwork dependent requirements for the ES-IS protocol are defined in subsequent (subnet-
work dependent) Parts of ISO/IEC ISP 10608.

6 Location of subnetwork-type specific requirements
Additional requirements that apply to end Systems according to the type(s) of subnetwork to which they are
attached are specified in subsequent Parts of ISO/IEC ISP 10608. The subnetwork-type specific require-
ments concern both the way in which specific subnetwork Services are provided by individual real subnet-
works and the way in which those specific subnetwork Services are used to provide the underlying Service
assumed by ISO 8473.
The following part numbers have been assigned in the expectation that they will be produced in the fore-
seeable future.

International Standardized Profile Implementation Conformance
Statement Requirements List (IPRL)
A.l lntroduction
The IPRL in this annex specifies the additional requirements for ISO 8073/Amd.3. The requirements of ISO
8073/Amd.3 apply to each item for which there is no entry in this IPRL.
The IPRL in this annex follows the proforma specified in ISO 8073/Amd.3. Since the TA Profile group uses
the transport protocol Class 4 exclusively, the items of the PICS for Classes 0 through 3 and Class 4 over
CONS do not need to be duplicated in the IPRL for the TA profiles. All references to transport classes 1
through 3 and Class 4 over CONS are out of the scope of ISOllEC ISP 10608.
A conforming implementation shall satisfy the mandatory conformance requirements of the base Standard
referenced in this patt of the Profile.
