外部定義

4.2

ACSE APDU

An APDU defined by the Association Control Service Element (ACSE).

4.3

Additional Network Feature

ANF

A capability provided by a PISN, not generally directly to a User, over and above that of the Basic call.

4.4

Adjacent PINX

A PINX as considered from another PINX to which it is directly connected via one or more inter-PINX links.

4.5

Application Protocol Data Unit

APDU

A sequence of data elements exchanged between peer application layer entities, e.g. ACSE APDUs, DSE APDUs and ROSE APDUs.

4.6

Call, Basic call

An instance of the use of a basic service.

4.7

Call independent signalling connection

A signalling connection established between SS-Control entities located in different PINXs that does not have an associated user-information connection.

4.8

Call independent

A property of information which is conveyed across the Q reference point in a message which does not use a call reference which has an associated user-information connection (that is, using a Connectionless or Connection oriented transport mechanism as defined in 7.2 or 7.3).

4.9

Call related

A property of information which is conveyed across the Q reference point in a message which uses a call reference which has an associated user-information connection.

4.10

Connection oriented

Communication between peer protocol entities by means of a connection or association established by an underlying layer.

4.11

Connectionless

Communication between peer protocol entities by means of an unacknowledged, unidirectional transport mechanism provided by an underlying layer.

4.12

Coordination Function

An entity which provides coordination between various SS-Control entities, ROSE, ACSE, DSE, GFT-Control and Call Control for different supplementary services (see clause 6).

4.13

Destination PINX

In the context of a single one-way exchange of information between two SS-Control entities, the PINX where the receiving SS-Control entity is located.

4.14

DSE APDU

An APDU defined by the Dialogue Service Element.

4.15

Dialogue Service Element

DSE

A service element which provides services to SS-Control via the Coordination Function that associate ROSE or ACSE APDUs which are not implicitly associated by an underlying network layer connection.

4.16

End PINX

In the context of a particular call, an Originating or Terminating PINX. It can also be a Gateway PINX, dependent on the capabilities of the signalling system being interworked (i.e. unless it transports APDUs unchanged to or from the other signalling system).

4.17

Gateway PINX

Sub-clause 4.6 of ISO/IEC 11572 shall apply. Dependent on the capabilities of the signalling system being interworked by the Gateway PINX, it can act as a Transit or an End PINX in the context of the supplementary services APDUs. That is, it can either transport the APDUs unchanged to or from the other signalling system, perhaps embedded in some other protocol unit, or process the APDUs and perform an interworking function of the information flows and encoding of the supplementary service concerned.

4.18

Generic Functional Transport Control (GFT-Control) entity

The entity that exists within a PINX and provides a range of services (defined in clause 6) to SS-Control, ROSE, ACSE and DSE via the Coordination Function.

4.19

Incoming side

In the context of a Call independent signalling connection, the Side which receives the request for connection establishment from the Preceding PINX.

4.20

Interpretation APDU

An APDU defined by the Coordination Function.

4.21

Inter-PINX link

The totality of a signalling channel and a number (≥ 0) of user information channels (which may have different characteristics) at the Q reference point.

4.22

Invocation

A request by a SS-Control entity to perform an operation in a remote SS-Control entity.

4.23

Link significance

A property of a Facility information element which does not contain a Network Facility Extension octet group. It indicates that the element has only significance on a single inter-PINX link - i.e. only between two Adjacent PINXs.

4.24

Mistyped

A property of an APDU whose structure does not conform to the structure defined in clause 11 of this International Standard or the structure defined for a particular supplementary service.

4.25

Network significance

A property of a Facility information element which includes a Network Facility Extension octet group. It indicates that the element has significance between two PINXs which are not necessarily Adjacent.

4.26

Next PINX

An Adjacent PINX to which an APDU is to be sent in the context of an existing signalling connection (related to a call or independent of a call).

4.27

Notification

4.28

Originating PINX

Sub-clause 4.5 of ISO/IEC 11572 shall apply. In addition, the term is also applied to a PINX which originates a Call independent signalling connection.

4.29

Outgoing side

In the context of a Call independent signalling connection, the Side which sends the request for connection establishment to the Next PINX.

4.30

PINX address

A PISN number as defined in ISO/IEC 11571 that is a complete number and that unambiguously identifies the addressed PINX or an addressable entity associated with that PINX.

4.31

Preceding PINX

Sub-clause 4.7 of ISO/IEC 11572 shall apply. In addition, the term is also applied in a similar way to a PINX participating in a Call independent signalling connection.

4.32

Private Signalling System No.1

The generic name given to the signalling protocol that exists conceptually at the ‘Q’ reference point and is defined in this and other Standards. This protocol is visible and indirectly testable at the ‘C’ reference point (see ISO/IEC 11579-1).

4.33

Protocol Control

An entity which exists within a PINX and provides a range of services (defined in clause 6) to the Generic Functional Transport Control entity.

4.34

ROSE APDU

An APDU defined by the Remote Operations Service Element (ROSE).

4.35

Side

The Protocol Control entity within a PINX at one end of an inter-PINX link.

4.36

Signalling Carriage Mechanism

SCM

The infrastructure that transports messages between Protocol Control entities in two interconnected PINXs.

4.37

Source PINX

In the context of a single one-way exchange of information between two SS-Control entities, the PINX where the sending SS-Control entity is located.

4.38

Subsequent PINX

Sub-clause 4.7 of ISO/IEC 11572 shall apply. In addition, the term is also applied in a similar way to a PINX participating in a Call independent signalling connection.

4.39

Supplementary service

Section 2.4 of ITU-T Recommendation I.210 shall apply.

For the purpose of this International Standard, ANFs shall be regarded as supplementary services.

4.40

An entity that exists within a PINX and provides the procedures associated with the support of a particular supplementary service.

4.41

4.42

Terminal, Terminal Equipment

An item of equipment attached to a telecommunication network to provide access for a user to one or more services.

4.43

Transit PINX

Sub-clause 4.5 of ISO/IEC 11572 shall apply. In addition, the term is also applied to a PINX which participates in the provision of a Call independent signalling connection, but does not originate or terminate that connection.

4.44

Unrecognised

A property of a message, information element, APDU or operation value whose type identifier is not one supported by the Destination PINX.
