SIST ETS 300 208 E1:2003 is the Slovenian standard identical to ETS 300 208 Edition 1, published by SIST and based on the European Telecommunications Standard from ETSI. It specifies the stage 1 service description for the Freephone (FPH) supplementary service in the pan-European Integrated Services Digital Network (ISDN). The document is written for service providers, network operators, and implementers who need to understand how freephone calls are offered, routed, presented, and charged from the user’s point of view.

What does SIST ETS 300 208 E1:2003 specify?

SIST ETS 300 208 E1:2003 defines the overall service behavior of the FPH supplementary service for ISDN. It focuses on the user-level service description, not on the human interface details or the signalling and switching protocols used to implement the service.

The standard covers interworking with public and private ISDNs, and it also sets out the basic functionality when FPH is offered through a private ISDN. It applies to circuit-switched telecommunications services and is intended as the stage 1 basis for the related stage 2 and stage 3 standards.

The document is organized into these main parts:

• Scope
• Normative references
• Definitions
• Symbols and abbreviations
• Description
• Procedures
• Intercommunication considerations
• Interaction with other supplementary services

What are the key requirements of SIST ETS 300 208 E1:2003?

SIST ETS 300 208 E1:2003 says that the FPH supplementary service shall be available to users connected through a basic access or a primary rate access. In practice, this means the service is defined for the main ISDN access types, so implementers can map the service to those access arrangements.

The core function is charge allocation: calls placed to the freephone number are charged to the served user. That is the central service promise and the basis for billing and call handling.

Clause 5.2 lists optional service controls that let the served user customize how calls are handled. These include time dependent control and routeing, origin dependent control and routeing, a call limiter, call distribution, alternative destination on busy or no reply, call queueing, indication of freephone call, presentation of freephone number, customer service profile management, and statistical information. In practice, these options let a service provider offer different handling rules for different customers or routes.

Clause 6 requires prior arrangement with the service provider before provision, and a freephone number shall be allocated on subscription. The foreword also describes two international service provision methods: one based on a bilateral arrangement between originating and terminating providers, and one where the originating provider handles routeing, logging, and billing.

Clause 6.2 describes normal procedures for registration, activation, invocation, and interrogation. A served user service profile is stored in the network and used as the running record for call handling. The calling user dials the service access code and freephone number, and the network processes the call according to the stored profile, either connecting the call or offering it to an announcement.

Clause 6.3 states that if the service cannot be invoked on a call, the call shall be rejected and the calling user informed. For implementers, this sets the fallback behavior when the freephone service cannot be applied.

Clause 7 requires support across internetwork interfaces, including interworking with non-ISDNs and private ISDNs. For PSTN interworking, no extra freephone requirements are added beyond the basic call, while mobile network providers shall not charge calling users for use of mobile network resources in this context.

Clause 8 defines interactions with other supplementary services. Examples include advice of charge, explicit call transfer, number identification services, diversion services, malicious call identification, and user-to-user signalling. These rules matter because they tell operators which service takes precedence and what information may be shown or recorded.

What terms does SIST ETS 300 208 E1:2003 define?

• Served user - the customer who has subscribed to the FPH supplementary service.
• Freephone number - the digit sequence assigned to the served user; together with the service access code, it forms the national part of an ISDN number.
• Freephone call - a call made to the freephone number.
• Service access code - the digits assigned to the FPH supplementary service that form the national destination code part of an ISDN number.
• Access arrangement - the installations or terminals connected to the served user’s access, such as a PABX or terminals.
• Routeing area - the area from which calls using a given freephone number are routed to one access arrangement or a set of access arrangements.
• Service profile - a record containing instructions for freephone call handling.
• FPH - Freephone.

Who uses SIST ETS 300 208 E1:2003?

SIST ETS 300 208 E1:2003 is used by European public telecommunications operators and service providers that offer ISDN supplementary services. It is also relevant to network engineers, signalling and switching implementers, and teams responsible for billing and customer service profile management.

It matters for organizations that need to define how freephone calls are accepted, routed, queued, transferred, or reported across public ISDN, private ISDN, and interworking networks.

Which standards are used with SIST ETS 300 208 E1:2003?

The standard cites these normative references:

• CCITT Recommendation I.130 - the framework for characterizing ISDN services and network capabilities.
• CCITT Recommendation I.112 - the vocabulary for ISDN terms.
• CCITT Recommendation I.210 - the principles used to describe ISDN telecommunication services.
• CCITT Recommendation Q.9 - the vocabulary of switching and signalling terms.
• CCITT Recommendation E.164 - the numbering plan used for ISDN numbers.

The foreword also names companion parts for the same service model:

• ETR 209 (1996) - stage 2 aspects of the FPH supplementary service.
• ETS 300 210 (1996) - stage 3 aspects of the FPH supplementary service.

What does the SIST ETS 300 208 E1:2003 document contain?

The document contains a stage 1 service description, so it concentrates on service behavior rather than protocol detail. It sets out the core service, optional handling features, provision and withdrawal rules, normal and exceptional procedures, intercommunication points, and interactions with other supplementary services.

It also contains the definitions needed to read the service model, along with the symbols and abbreviations used in the text. The interaction clauses are especially useful for implementers because they show how FPH behaves with call forwarding, identification services, malicious call identification, and user-to-user signalling.

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 Freephone (FPH) supplementary
service. The stage 2 and stage 3 aspects are detailed in ETR 209 (1996) and ETS 300 210 (1996),
respectively.

1 Scope
This standard defines the stage one of the Freephone (FPH) 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 FPH supplementary service is provided to
the user via a private ISDN.
This standard does not specify the additional requirements where FPH supplementary 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.
Interactions with supplementary services not listed in clause 8 are outside the scope of this standard.
Charging principles are outside the scope of this standard, unless specific service requirements are
stated. These requirements deal with the allocation of certain call charges to particular users.
The FPH supplementary service enables to allocate to the served user the charges for calls placed to the
freephone number.
The FPH supplementary service is applicable to all circuit-switched telecommunication services.
This standard is applicable to the stage two and stage three standards for the ISDN FPH 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 standards 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.
