FOREWORD
1) The IEC (International Electrotechnical Commission) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of the IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, the IEC publishes International Standards. Their preparation is
entrusted to technical committees; any IEC National Committee interested in the subject dealt with may
participate in this preparatory work. International, governmental and non-governmental organizations liaising
with the IEC also participate in this preparation. The IEC collaborates closely with the International Organization
for Standardization (ISO) in accordance with conditions determined by agreement between the two
organizations.
2) The formal decisions or agreements of the IEC on technical matters express, as nearly as possible, an
international consensus of opinion on the relevant subjects since each technical committee has representation
from all interested National Committees.
3) The documents produced have the form of recommendations for international use and are published in the form
of standards, technical specifications, technical reports or guides and they are accepted by the National
Committees in that sense.
4) In order to promote international unification, IEC National Committees undertake to apply IEC International
Standards transparently to the maximum extent possible in their national and regional standards. Any
divergence between the IEC Standard and the corresponding national or regional standard shall be clearly
indicated in the latter.
5) The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with one of its standards.
6) Attention is drawn to the possibility that some of the elements of this International Standard may be the subject
of patent rights. The IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 61162-410 has been prepared by IEC technical committee 80:
Maritime navigation and radiocommunication equipment and systems
The text of this standard is based on the following documents:
FDIS Report on voting
80/311/FDIS 80/326/RVD

voting indicated in the above table.
This publication has been drafted in accordance with the ISO/IEC Directives, Part 3.

INTRODUCTION
International Standard IEC 61162 is a four-part standard which specifies four digital interfaces
for applications in marine navigation, radiocommunication and system integration.
The four parts are:
IEC 61162-1 Single talker and multiple listeners
IEC 61162-2 Single talker and multiple listeners, high speed transmission
IEC 61162-3 Multiple talkers and multiple listeners – Serial data instrument network
IEC 61162-4 Multiple talkers and multiple listeners – Ship systems interconnection.
Part 4 of the standard is subdivided into a number of individual standards with part numbers in
the 400 series.
This part of the standard contains the specification of the requirements to an IEC 61162-4
transport profile (T-profile) and also the specification of one implementation, based on
redundant Ethernet and Internet protocol functionality. The T-profile is the protocol transport
mechanisms that offer simple message or byte stream transport services to the higher protocol
layers (defined in other parts of the standard). In addition, the T-profile also offers services for
time distribution and physical network management.
The use of Internet and Ethernet protocols offer low cost and high efficiency data transport in
any kind of system. However, for safety related applications, certain measures have to be
taken to avoid that particulars of office-quality and off-the-shelf technology create safety risks.
This part of the standard specifies mechanisms by which a certain degree of quality of service
can be guaranteed from these networks, including the provision of redundancy.
Other T-profile documents will be prepared with specifications of the same T-profile require-
ments over other transport protocols. This will be issued in the same number series as this
standard (IEC 61162-41x).
Relationship with the other parts of the IEC 61162 series of standards is defined in annex B to
IEC 61162-400.

Transport profile requirements and basic transport profile
1 Scope and object
This part of IEC 61162-4 defines the general requirements of the T-profile and three
implementations of the T-profile over the Internet V4 (IPV4) protocol suite. Part 400 of this
standard defines the relationship between the different protocol levels (T-profile, A-profile and
companion standards) and part 401 defines the A-profile, the immediate user of the protocol
level defined in this part.
The different components of the IEC 61162-4 standard are defined in IEC 61162-400. The
T-profile is the specification of the communication services and the communication protocols
used by the LNA to implement the A-profile functionality. Basically, the T-profile consists of the
following components:
a) a transport layer interface (TLI) definition that specifies the services and the semantics that
will be available to the application level of the LNA (and in some cases the MAU). This
includes data transport as well as time and network management services. The TLI will be
general to all T-profiles and is defined in this part 410 of the standard,
b) A T-profile protocol definition that specifies how the services provided by the TLI and
additional time distribution and physical network management services are implemented on
the protocol level. This part 410 contains a number of alternative T-profile protocol
specifications using the Internet V4 series of standards. Additional parts of this standard
will address other T-profiles based on other protocol families.
Note that the time distribution and network management functionality may or may not include
specific TLI services. For some systems this functionality may be interfaced to directly by the
underlying operating system. Note also that time distribution and network management are not
strictly speaking transport related protocol functionality. However, the implementation of these
services is normally dependent on the transport protocols in use and is, thus, placed in the
T-profile part of the standard.
The purpose of this standard is to define and describe the services that will be provided at the
transport level interface in a way which is completely independent of the underlying network
environment as well as defining one possible implementation of these services over the
Internet V4 protocols. The separation of service and protocol definitions allows the
specification of several different transport profiles, each one dedicated to a specific network
environment, and to use the same transport service interface in all cases.
Clause 4 defines the transport level services and clause 5 describes the transport layer
interface through which the services are offered. These clauses define the general, network
independent services.
Clause 6 defines the transport profile architecture for redundant Ethernet and Internet
protocols version 4 (IPV4). Clause 7 defines the architecture for a local area non-redundant
Internet network. These clauses define two specific implementations of the T-profile services.

61162-410  IEC:2001(E) – 9 –
Clause 8 defines a simple MAU-LNA protocol for use over wide area network (WAN) TCP/IP
links. This can be used to implement a WAN architecture for the overall system. The WAN
architecture is not intended for integrated ship control systems, but can be used for remote test
integration and remote maintenance and diagnostics. The WAN protocol can also be used to
support MAUs that are located in other host computers than the LNA, but on one local network
(conformance class 4).
