SIST ETS 300 178 E1:2003 is the Slovenian adoption of ETS 300 178 Edition 1 from ETSI. It describes the stage 1 service for the Integrated Services Digital Network (ISDN) Advice Of Charge: charging information at call set-up time (AOC-S) supplementary service, for users of pan-European ISDN and the public telecommunications operators that provide it.
What does SIST ETS 300 178 E1:2003 specify?
SIST ETS 300 178 E1:2003 specifies the user-level service description for AOC-S in ISDN. It says what charging information is given at call set-up time, how later rate changes are reported, how the service behaves with private ISDNs and other services, and how the charging information is structured in Annex A.
The document is organized into:
- Clause 1 Scope
- Clause 2 Normative references
- Clause 3 Definitions
- Clause 4 Symbols and abbreviations
- Clause 5 Description
- Clause 6 Procedures
- Clause 7 Intercommunication considerations
- Clause 8 Interaction with other supplementary services
- Annex A, which is normative
| Annex | What it covers |
|---|---|
| Annex A | Structure, contents and application of charging information, including charging items and charging rate forms |
The scope is narrow in a useful way. It covers the stage 1 description from the user's point of view, but not the human interface details, charging principles, or services outside the interactions listed in Clause 8.
What are the key requirements of SIST ETS 300 178 E1:2003?
Service coverage and user visibility
Clause 5 states that AOC-S applies to both basic access and primary rate access. In practice, the service is not tied to one ISDN access type, so implementers need to support it across the access methods named in the document.
Clause 5 also says the served user receives charging-rate information at call establishment, and is informed again if the rate changes during the call. That means the network must be able to present an initial rate picture and later updates, not just a single price at the start.
Provision, invocation and normal operation
Clause 6.1 allows AOC-S to be provided either by subscription or as generally available, with one subscription option: invocation for all calls automatically or on a per-call basis. This matters because the provider has to choose how the user activates the service and whether it is always on or requested per call.
Clause 6.2.1 says activation follows provision, deactivation follows withdrawal, and no registration is required. Clause 6.2.3 says that when the per-call option is used, the user must request AOC-S when originating the call. In practice, terminals and switches need a clear trigger point for the request.
Clause 6.2.3 also states that charging information is supplied during call establishment, at the latest when the calling user is told that the called user has accepted the call. If the charging rate changes during the call, the new rate must be sent. If the call is free of charge, or becomes free of charge during the active phase, the specific rate "free of charge" is used.
Exceptional cases and interworking
Clause 6.3.3 requires the network to reject an attempt to invoke AOC-S by a served user who does not have it, and to give the reason. It also requires "not available" when charging information is missing or incomplete. That means users must not assume a call is free simply because no charging data was delivered.
Clause 7 says there is no impact on AOC-S operation when interworking with non-ISDNs, and that AOC-S shall be supported across the internetwork interface between ISDNs, whether public or private. For real deployments, this is the part that matters when calls cross network boundaries.
Interaction with other supplementary services
Clause 8 lists the supplementary services that interact with AOC-S, including call waiting, call hold, explicit call transfer, number identification services, closed user group, completion of calls to busy subscriber, conference services, diversion services, freephone, malicious call identification, multiple subscriber number, subaddressing, terminal portability, three party, and user-to-user signalling.
Some interactions have specific behavior. For conference call, add-on, the conference controller can receive updated charging-rate information for the whole conference, and a call added to a conference does not get further rate information on its own. For freephone, the document states that AOC-S information is not sent to the called freephone user. For terminal portability, a rate change during suspension is reported when the call is resumed. For three party, charging information can be sent as a network option.
Charging information structure
Annex A defines what charging information can be carried. It identifies charging-rate information and charged items such as basic communication, call attempt, call setup, special charging arrangement, user-to-user information transfer, and operation of supplementary services. It also sets the allowed rate forms, including duration rate, volume rate, and specific rate, so implementers know how the network may encode the charge data.
What terms does SIST ETS 300 178 E1:2003 define?
- Advice Of Charge: charging information at call set-up time (AOC-S) - The supplementary service that gives charging-rate information when a call starts and when rates change during the call.
- Integrated Services Digital Network (ISDN) - The digital network environment in which this supplementary service is defined.
- Supplementary service - A telecommunications service added to the basic service, as referenced from CCITT Recommendation I.210.
- Served user - The user to whom the AOC-S supplementary service is provided.
- Basic access - The ISDN access form identified by the document through CCITT Recommendation Q.9.
- Primary rate access - The other ISDN access form named in the document through CCITT Recommendation Q.9.
Who uses SIST ETS 300 178 E1:2003?
SIST ETS 300 178 E1:2003 is used by public telecommunications operators that provide ISDN supplementary services. It is also relevant to private ISDN operators and to anyone who needs AOC-S to interwork between public and private ISDN environments.
In practice, the main users are service planners, network engineers, switch and terminal implementers, and standards engineers working on the related stage 2 and stage 3 specifications. Quality and compliance teams use it to check that charging information is presented at the right time and in the right form for the intended service model.
What changed in SIST ETS 300 178 E1:2003 from the previous edition?
SIST ETS 300 178 E1:2003 corresponds to ETS 300 178 Edition 1. The history records the first edition in October 1992 and a PDF conversion in January 1996.
Which standards are used with SIST ETS 300 178 E1:2003?
The normative references and related parts named in the document are:
- CCITT Recommendation I.130 - Gives the method used to characterize ISDN services and the three-stage structure for service description, which is the framework used by this document.
- CCITT Recommendation I.112 - Provides the vocabulary of terms for ISDNs, including the definitions of ISDN and service.
- CCITT Recommendation I.210 - Gives the principles of telecommunication services supported by ISDN and the means to describe them, including supplementary service.
- CCITT Recommendation Q.9 - Provides switching and signalling vocabulary, including the access terms used in the definitions.
- ETS 300 181 (1992) - Gives the stage 2 aspects for the AOC-S supplementary service.
- ETS 300 182 (1992) - Gives the stage 3 aspects for the AOC-S supplementary service.
What does the SIST ETS 300 178 E1:2003 document contain?
The document contains a short service description, the procedure model, interworking notes, and service interactions. Clause 6 includes a subscription-option table that distinguishes invocation for all calls from per-call invocation.
Annex A contains the charging-information structure, including the list of charged items and the permitted charging-rate forms. It also gives the application rules for currency-unit charging information, special charging arrangements, and cases where a charged item is omitted or marked "not available". For implementers, this is the part that turns the service description into data that can be signalled, displayed, or checked in a switch or terminal.

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 call set-up time (AOC-S) 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 at call set-up time
(AOC-S) 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-S supplementary service enables a user to receive information about the charging rates at call
set-up time and also to receive further information during the call if there is a change of charging rates.
The AOC-S 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-S
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

AOC-S Advice Of Charge: charging information at call set-up time
ISDN Integrated Services Digital Network
5 Description
The AOC-S supplementary service shall apply to the basic access and to the primary rate access.
The AOC-S supplementary service provides the served user with information about the charging rates at
call establishment. In addition, the served user shall be informed if a change in charging rates takes place
during the call. The information can be sent for all calls, or on a per call basis. The charge information
given shall relate to the charges incurred on the network to which the served user is attached.
NOTE: In some cases, e.g. due to off-line processing of charges, or timing considerations, the
charge calculated by the user or the user's equipment may not precisely reflect the
actual cost incurred.
The structure, contents and application of charging information is given in Annex A.
6 Procedures
6.1 Provision and withdrawal
The AOC-S supplementary service shall either be provided on a subscription basis or be generally
available. The AOC-S supplementary service can be offered with one subscription option. Only one value
can be selected.
