Foreword
IS0 (the International Organization for Standardization) and IEC (the International Electrotechnical Commission) form the
specialized system for worldwide standardization. National bodies that are members of IS0 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. IS0 and IEC technical committees collaborate in fields of mutual interest. Other
international organizations, governmental and non-governmental, in liaison with IS0 and IEC, also take part in the work.
In the field of information technology, IS0 and IEC have establiihed a joint technical committee, ISO/IEC JTC 1. Draft
International Standards adopted by the joint technical committee are circulated to national bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the national bodies casting a vote.
International Standard ISO/IEC 10737 was prepared by joint Technical Committee ISO/IEC JTC 1, Information technology,
Subcommittee SC 6, Telecommunications and information exchange between systems.
Annex A forms an integral part of this International Standard. Aqnexes B and C are for information only.

Introduction
This document is one of a set of International Standards produced to facilitate the interconnection of open systems. The set of
International Standards covers the services, protocols and management information required to achieve such interconnection.
This International Standard is positioned with respect to other related International Standards by the layers defined in the
Reference Model for Open Systems interconnection (IS0 7498). In particular, it is concerned with the definition of Transport
Layer management information.

5 Elements of Transport Layer Management Information
5.1 Managed Object Hierarchy
5.1.1 Summary of managed objects
The following set of managed objects are defined for the Transport Layer:
Transport Subsystem managed object (transportSubsystem, see 5.3)
a)
Transport Entity managed object (transporflntity, see 5.4)
b)
Connectionless Transport Protocol Machine managed object (clmodeTPM, see 5.5)
cl
Connection-Oriented Transport Protocol Machine managed object (comodeTPM, see 5.6)
d)
Transport SAP managed object (tSAP, see 5.7)
e)
Transport Connection managed object (transportConnection, see 5.8.1)
f)
Transport Connection Initial Values managed object (transportConnectionIVM0, see 5.8.2)
g)
These Managed Objects represent OS1 Management's view of those elements of an Open System which support the OS1
Transport Service subject to OS1 management operations. The containment hierarchy is illustrated in figure 1. Managed
objects which can have multiple instances are illustrated by multiple boxes. These objects are defined in detail in the following
subclduses.

5.1.3 Minimum Event Filtering Capabilities
The transport layer management definitions embodied in this specification imply the frequent and possibly excessive
generation of notifications of notifications during regular layer operation. These notifications are especially useful for effective
fault management where they facilitate the tracing and pinpointing of error situations. To avoid the excessive dissemination of
these event reports under normal operating conditions, it is advisable for a managed system to have as a minimum the
capability to perform discrimination based on
the source managed object class;
a)
the object Identifier values in the probable cause and specific problems field of Communication alarms, and the
b)
communication type field of Communication informations.
5.1.4 Use of Optional Fields
Where reference is made in this International Standard to ASN.l syntax defined in Rec. X.723 I ISO/IEC 10165-5 or
Rec.X.721 I ISOAEC 10165-2, only the following fields shall be employed:
those which are not OPTIONAL in the ASN.l syntax;
a)
those which are OPTIONAL, but whose use is explicitly required by this International Standard;
b)
those which are OPTIONAL, but whose ASN.l type is SET OF MngmntExtension.
c)
The use of any other field is prohibited.
5.2 Common Transport Layer GDMO Definitions
commonCreationDeletion-B BEHAVIOUR
DEFINED AS
!Managed object class imports the 10165-2 objectcreation and objectDeletion
notifications. Used as follows:
Objectcreation - Generated whenever an instance of the managed object class is
created. Implementations may optionally include the sourceIndicator parameter ii
the notification. If creation occured as a result of internal operation of the
resource, the value 'resourceOperation' is used.If creation occured in response
to a management operation, the value 'managementoperation' is used. A value of
'unknown' may be returned if it is not possible to determine the source of the
operation. None of the other optional parameters are used.
ObjectDeletion - Generated whenever an instance of the managed object class is
deleted. Implementations may optionally include the sourceIndicator parameter in
the notification. if deletion occured as a result of internal operation of the
resource, the value 'resourceOperation' is used. If deletion occured in response
to a management operation, the value 'managementoperation' is used. A value of
'unknown' may be returned if it is not possible to determine the source of the
operation. None of the other optional parameters are used.!;
commonStateChange-B BEHAVIOUR
DEFINED AS
!Managed object class imports the 10165-2 statechange notification. Used to
report the changes to the operationalstate attribute, and where present, the
administrativeState attribute. A single parameter set is included in the State
change definition field. Only the (mandatory) attributeId and (optional)
newAttributeValue parameters are used.!;
octetsSentReceivedCounter-B BEHAVIOUR
DEFINED AS
!The octetsSentCounter and octetsReceivedCounter shall count only user data
octets in valid data TPDUs. They shall not count user data octets in data TPDUs
which are rejected for any reason, nor user data octets in non-data TPDUs.!;

---------------------- Page: 11 ----------------------
O ISOIIEC ISOBEC 10737:1994(E)
successfulConnectionEstablishment-B BEHAVIOUR
DEFINED AS
!This Package imports the comunicationsInformation notification from "GMI". It
is used to report the following events :
successfulConnectionEstablishment: Generated when a connection is successfully
established. However the precise synchronization between the notification and
the corresponding protocol and service interface interactions is not defined by
this Specification
The value TLM.successfu1ConnectionEstablishment shall be reported in the
informationType field.!;
deactivateConnection-B BEHAVIOUR
DEFINED AS
!The deactivate action causes the connection to be terminated. The termination
should occur as rapidly as practical, but no particular time constraints are
implied. Typically, this action simulates a disconnect request received across
the service interface. If a more rapid means for terminating the connection
exists, then this should be used. The termination shall occur in conformance to
the protocol standard. The Managed Object remains in existence after completion
of the Deactivate Action. It is subsequently deleted when the connection is
B
terminated, in the same way as if the connection has been terminated by other
means. A Deactivate action may fail (with the ProcessingError response) if it is
temporarily not possible to terminate the connection.!;
resettingTimer-B BEHAVIOUR
DEFINED AS
!This attribute specifies the interval between certain events in the operation
of the protocol state machine. If the value of the attribute is changed to a new
value while the protocol state machine is in operation, the implementation shall
take the necessary steps to ensure that for any time interval which was in
progress when the corresponding attribute was changed, the next expiration of
that interval takes place no later than the expiration of the interval in
progress or the specified interval whichever is the sooner. The precision with
which this time shall be implemented shall be the same as that associated with
the basic operation of the timer attribute.!;

connection-mode protocol, and if it has been possible to relate the PDU to a
particular connection. The reason code is the value placed in the corresponding
parameter of the ER TPDU, if sent. The tEPackage imports the communicationsAlarm
Notification from DMI, in order to report the ProtocolError event. The
probablecause shall be sqt to TLM.communicationsProtocolError. The
