SIST ETS 300 179 E1:2003 is a SIST publication based on ETS 300 179 Edition 1 for the Integrated Services Digital Network (ISDN) Advice Of Charge: charging information during the call (AOC-D) supplementary service. It specifies the stage 1 service description - what the service does, how it is provided and invoked, and how charging information is reported during a call - for ISDN service providers, network designers and implementers.

What does SIST ETS 300 179 E1:2003 specify?

SIST ETS 300 179 E1:2003 defines the user-level service description of AOC-D for the pan-European ISDN. It focuses on how a served user receives charging information during the active phase of a call, with interworking for private ISDNs and the public ISDN.

The scope keeps the document at service-description level. It covers service behavior, but not charging principles or detailed human-interface design.

The document is organized as follows:

• Clauses 1-4 cover scope, normative references, definitions, and symbols/abbreviations.
• Clause 5 describes the service.
• Clause 6 covers provision, activation, invocation, and exceptional behavior.
• Clause 7 covers intercommunication considerations.
• Clause 8 covers interaction with other supplementary services.
• Annex A defines the structure and application of charging information.

What are the key requirements of SIST ETS 300 179 E1:2003?

Service model and access

SIST ETS 300 179 E1:2003 says that AOC-D applies to both basic access and primary rate access. In practice, that means the service is available across the main ISDN access types used for circuit-switched services.

Clause 5 states that the service provides cumulative charging information during the call. The information may be sent for all calls automatically or on a per-call basis, and it relates to the network to which the served user is attached.

Provision and invocation

Clause 6.1 allows AOC-D to be provided by subscription or as a generally available service. The document also allows only one subscription option value at a time: invoke for all calls automatically, or invoke on a per-call basis.

Clause 6.2 says the service is activated on provision, deactivated on withdrawal, and requires no registration. If the service is per-call, the served user must request it when originating the call. For readers implementing service control, this is the point where user action and network behavior must align.

Charging information during the call

Clause 6.2.3 requires the network to send charging information when an appropriate cost increment occurs. The sending rate can be limited by a network option, with a minimum interval controlled by the network.

The clause also requires explicit handling when the call is free of charge, including a final overall charge at call termination. If charging information is unavailable, the network must indicate that state, and the user must not assume the call was free of charge.

Exceptional behavior and interworking

Clause 6.3 covers cases where invocation is attempted without the service, or where charging information is incomplete or unavailable. Clause 7 states that interworking with non-ISDNs has no impact on operation, and that the service shall be supported across ISDN internetwork interfaces.

For implementers, this means AOC-D must remain understandable when calls move across ISDN domains, including public and private ISDNs.

Interactions with other supplementary services

Clause 8 explains how AOC-D behaves with call waiting, call hold, explicit call transfer, number identification services, closed user group, conferencing, diversion, freephone, terminal portability, three party, and user-to-user signalling.

One practical example is explicit call transfer: when a user transfers a call, the charge up to that point is sent as a subtotal and AOC-D is considered complete. Annex A also matters here because it defines the exact forms of subtotal and total charging information.

What terms does SIST ETS 300 179 E1:2003 define?

• Integrated Services Digital Network (ISDN) - the network environment in which AOC-D is specified.
• Advice Of Charge: charging information during the call (AOC-D) - the supplementary service that sends charging information while the call is active.
• Supplementary service - a service that adds capability to a telecommunications service.
• Served user - the user to whom AOC-D is provided.
• Basic access - an ISDN access type covered by the service.
• Primary rate access - another ISDN access type covered by the service.
• Free of charge - charging information indicating no charge to the served user.
• Not available - charging information indicating that some or all recorded charges cannot be provided.

Who uses SIST ETS 300 179 E1:2003?

SIST ETS 300 179 E1:2003 is used by ISDN service providers, public telecommunications operators, and private ISDN operators that need to describe or offer AOC-D. It also supports network architects, signalling and switching engineers, and equipment implementers who must make the service behave consistently across access types and interworking cases.

It is also useful for buyers and quality managers checking whether a proposed ISDN service or platform matches the expected charging-information behavior.

What changed in SIST ETS 300 179 E1:2003 from the previous edition?

SIST ETS 300 179 E1:2003 corresponds to ETS 300 179 Edition 1. The history identifies it as the first edition of the standard.

Which standards are used with SIST ETS 300 179 E1:2003?

• CCITT Recommendation I.130 - gives the three-level method used to describe ISDN services.
• CCITT Recommendation I.112 - provides ISDN vocabulary used in the definitions.
• CCITT Recommendation I.210 - gives principles for ISDN services and how to describe them.
• CCITT Recommendation Q.9 - provides switching and signalling vocabulary used for access terms.
• ETS 300 181 (1992) - covers the stage 2 aspects of AOC-D.
• ETS 300 182 (1992) - covers the stage 3 aspects of AOC-D.

What does the SIST ETS 300 179 E1:2003 document contain?

The document contains the service description, procedure rules, interworking notes, and interaction cases for AOC-D. It includes a subscription-option table in Clause 6 and a normative Annex A that defines subtotal charges, total charges, recorded charges, billing identification, and how charging information is applied.

It also gives explicit handling for special cases such as free calls, unavailable charging data, call hold, explicit call transfer, conference calls, diversion services, freephone, terminal portability, and three party operation. These details are the parts readers usually need when designing, specifying, or verifying charging-information behavior.

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 during the call (AOC-D) supplementary service. Stage 2 and stage 3 aspects are detailed in
ETS 300 181 (1992) and ETS 300 182 (1992), respectively.

1 Scope
This standard defines the stage one of the Advice Of Charge: charging information during the call
(AOC-D) 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-D supplementary service enables a user to receive information on the recorded charges for a
call during the active phase of the call.
The AOC-D 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-D
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.
