SIST ETS 300 180 E1:2003 is the Slovenian adoption of ETS 300 180 Edition 1 from ETSI. It specifies the stage 1 service description for the Advice of Charge: charging information at the end of the call (AOC-E) supplementary service in Integrated Services Digital Network (ISDN). In practice, it explains when charge information is given to the served user, how the service is invoked, and how it behaves with other supplementary services.

What does SIST ETS 300 180 E1:2003 specify?

SIST ETS 300 180 E1:2003 defines the AOC-E supplementary service from the user's point of view. It covers public ISDN service provision, interworking with private ISDNs, and the base functionality when the service is offered through a private ISDN.

Annex	What it covers
A	Structure, contents and application of charging information

The scope also says that charging principles are outside the document, as are interactions with supplementary services not listed in Clause 8. The document is organized into clauses for scope, references, definitions, symbols and abbreviations, description, procedures, intercommunication considerations, interaction with other supplementary services, and Annex A.

What are the key requirements of SIST ETS 300 180 E1:2003?

SIST ETS 300 180 E1:2003 sets out a stage 1 service description, so it tells you how AOC-E should behave rather than how to signal it. That matters because operators, implementers, and buyers need the service model before they can specify equipment or service profiles.

Service availability and invocation

Clause 5 says AOC-E applies to both basic access and primary rate access. The served user receives charging information when the call ends, and the service can work automatically for all calls or on a per-call basis.

Clause 6.1 allows the service to be provided by subscription or made generally available. Only one subscription option is used, so the service profile has a clear choice between automatic invocation and per-call invocation. That affects how the user subscribes and how the network applies the service.

Clause 6.2 says the service is activated when provided and deactivated when withdrawn, and it requires no registration. For a per-call option, the user must request AOC-E when originating the call. In practice, this means the network must know at call setup whether the user wants charge information for that specific call.

Charging information at call end

Clause 6.2.3 requires the network to provide charging information when the call terminates. If the call is free of charge, the network indicates that fact explicitly. If charge information is not available, the user is told that it is not available and cannot assume the call was free.

Annex A defines the structure of the charging information. It covers total charges, recorded charges, and billing identification. It also allows the network to present charges in charging units or currency units, which matters when the service must match the network’s billing practice.

Interworking and interaction with other services

Clause 7 says interworking with non-ISDNs does not change the operation of AOC-E, and interworking between public and private ISDNs shall be supported across the inter-network interface. That makes the service relevant for mixed network environments.

Clause 8 gives the interaction rules with other supplementary services. If charging information during the call and AOC-E are both used, only the AOC-E information is given at the end of the call. Clause 8 also covers explicit call transfer, call forwarding unconditional, call forwarding busy, call forwarding no reply, call deflection, conference call add-on, terminal portability, and three party. These clauses describe when charge information may be passed to another user as a network option and when it must not be sent, such as for Freephone.

What terms does SIST ETS 300 180 E1:2003 define?

• Integrated Services Digital Network (ISDN) - The network context used by the standard for this supplementary service.
• AOC-E - Advice of Charge: charging information at the end of the call, the service described by the document.
• Served user - The user to whom the AOC-E supplementary service is provided.
• Basic access - An ISDN access type covered by the service.
• Primary rate access - The other ISDN access type covered by the service.
• Supplementary service - A telecommunications service that adds to the basic service.
• Billing identification - The charge category supplied with recorded charges to show how the call was billed.

Who uses SIST ETS 300 180 E1:2003?

Telecommunications operators and service providers use this standard to define how AOC-E is offered on public ISDNs and across public/private ISDN interfaces. Network engineers and service designers use it to configure automatic and per-call invocation, termination behavior, and service interactions.

Equipment implementers use it when designing switches and ISDN service functions that must support charge information at call end. Billing and service-management teams use Annex A to align the network’s recorded charges with what is presented to the served user. It is also useful for quality and procurement checks when a service description is needed for a specific ISDN feature set.

What changed in SIST ETS 300 180 E1:2003 from the previous edition?

SIST ETS 300 180 E1:2003 is identical to ETS 300 180 Edition 1. The history in the ETS identifies it as the first edition, published in October 1992.

Which standards are used with SIST ETS 300 180 E1:2003?

• CCITT Recommendation I.130 - Provides the three-stage model used to describe ISDN supplementary services.
• CCITT Recommendation I.112 - Supplies ISDN vocabulary and the definitions of ISDN and service.
• CCITT Recommendation I.210 - Sets out the principles for describing telecommunication services supported by ISDN.
• CCITT Recommendation Q.9 - Supplies switching and signalling vocabulary, including access terms.
• ETS 300 181 (1992) - Covers the stage 2 aspects for AOC-E.
• ETS 300 182 (1992) - Covers the stage 3 aspects for AOC-E.

What does the SIST ETS 300 180 E1:2003 document contain?

The document contains a service description, the procedure model for provision and withdrawal, normal and exceptional operation, interworking notes, and a long clause on interactions with other supplementary services. Clause 6 includes a table for the subscription option values, which helps operators choose between automatic and per-call invocation.

Annex A gives the structure and application of charging information used at call end. It describes the charge categories that can be reported, the billing identification options, and how the information is applied to the served user. The document does not provide a testing method, because conformance is tied to the corresponding stage 3 standard for the relevant equipment field of application.

Foreword
This European Telecommunication Standard (ETS) has been produced by the Network Aspects (NA)
Technical Committee of the European Telecommunications Standards Institute (ETSI).
In accordance with CCITT Recommendation I.130 [1], the following three level structure is used to
describe the supplementary telecommunications services as provided by European public
telecommunications operators under the pan-European Integrated Services Digital Network (ISDN):
- Stage 1: is an overall service description, from the user's standpoint;
- Stage 2: identifies the functional capabilities and information flows needed to support the service
described in stage 1; and
- Stage 3: defines the signalling system protocols and switching functions needed to implement the
service described in stage 1.
This ETS details the stage 1 aspects (overall service description) for the Advice Of Charge: charging
information at the end of a call (AOC-E) supplementary service. Stage 2 and stage 3 aspects are detailed
in ETS 300 181 (1992) and 300 182 (1992) respectively.

1 Scope
This standard defines the stage one of the Advice Of Charge: charging information at the end of the call
(AOC-E) supplementary service for the pan-European Integrated Services Digital Network (ISDN) as
provided by European public telecommunications operators. Stage one is an overall service description
from the user's point of view (see CCITT Recommendation I.130 [1]), but does not deal with the details of
the human interface itself.
This standard defines the interworking requirements of private ISDNs with the public ISDN.
In addition, this standard specifies the base functionality where the service is provided to the user via a
private ISDN.
This standard does not specify the additional requirements where the service is provided to the user via a
telecommunications network that is not an ISDN but does include interworking requirements of other
networks with the public ISDN.
Charging principles are outside the scope of this standard.
Interaction with supplementary services not listed in Clause 8 are outside the scope of this standard.
The AOC-E supplementary service enables a user to receive information on the recorded charges for a
call when the call is terminated.
The AOC-E supplementary service is applicable to all circuit-switched telecommunications services.
This standard is applicable to the stage two and stage three standards for the ISDN AOC-E
supplementary service. The terms "stage two" and "stage three" are also defined in CCITT
Recommendation I.130 [1]. Where the text indicates the status of a requirement (i.e. as strict command or
prohibition, as authorisation leaving freedom, or as a capability or possibility), this shall be reflected in the
text of the relevant stage two and stage three standards.
Furthermore, conformance to this standard is met by conforming to the stage three standard with the field
of application appropriate to the equipment being implemented. Therefore, no method of testing is
provided for this standard.
2 Normative references
This standard incorporates, by dated or undated reference, provisions from other publications. These
normative references are cited at the appropriate places in the text and the publications are listed
hereafter. For dated references, subsequent amendments to, or revisions of, any of these publications
apply to this standard only when incorporated in it by amendment or revision. For undated references the
latest edition of the publication referred to applies.
