Overview

SIST ETS 300 648 E1:2004 defines the Calling Line Identification Presentation (CLIP) supplementary service for the Public Switched Telephone Network (PSTN). Developed by SIST and harmonized with ETSI standards, this document provides a comprehensive service description (stage 1) from the user's point of view. CLIP is designed to display the caller’s telephone number to the recipient, improving user awareness and supporting a safer, more efficient calling experience for both residential and business subscribers.

This standard applies to analog PSTN access and addresses requirements for interworking with private networks, Integrated Services Digital Networks (ISDN), and Public Land Mobile Networks (PLMN). The document clarifies the operation, provision, and interaction of CLIP with related services and network environments.

Key Topics

• Service Description: Offers a user-centric overview of CLIP, explaining how calling line information is presented to the called party during call establishment.
• Provision and Withdrawal: Discusses how CLIP may be activated or deactivated by the service provider either by subscriber request or as a general service, and how users can sometimes control activation themselves.
• Normal and Exceptional Procedures: Details the actions for activation, deactivation, invocation, and status interrogation, including expected network behavior under exceptional circumstances (e.g., identity restriction or insufficient signaling).
• Interworking: Explores intercommunication, including handling of CLIP data between PSTN and ISDN, private networks, and PLMNs.
• Service Interactions: Examines the relationship between CLIP and supplementary services such as Calling Line Identification Restriction (CLIR), clarifying when one service overrides another.
• Abbreviations and Definitions: Provides clear terminology for key concepts such as calling line identity, analogue access, and relevant acronyms like CLIP, CLIR, ISDN, PBX, PLMN, and PSTN.

Applications

CLIP supplementary service is deployed widely across telephone networks to enhance both security and convenience for customers. Key applications include:

• Caller Identification for PSTN Subscribers: Allows users to identify the incoming caller before answering, reducing unwanted or fraudulent calls.
• Business Solutions: Assists organizations in managing incoming communications, supporting customer service, and integrating with PBX systems for streamlined telephony.
• Network Interworking: Ensures seamless operation when calls traverse multiple network types (e.g., a call originating from a mobile network and terminating on a fixed-line PSTN).
• User Control: In some network implementations, end users can activate, deactivate, or interrogate the service, offering flexibility to suit individual preferences.
• Fraud Prevention and Screening: Empowers users to screen calls more efficiently, increasing personal safety and protecting business resources.

Related Standards

For a complete implementation and understanding of CLIP in PSTN environments, the following related standards should be consulted:

• ETS 300 089: Integrated Services Digital Network (ISDN); Calling Line Identification Presentation (CLIP) supplementary service - Service description
• ETS 300 090: ISDN; Calling Line Identification Restriction (CLIR) supplementary service - Service description
• ETS 300 649: PSTN; Calling Line Identification Restriction (CLIR) supplementary service - Service description
• ETS 300 659-1: PSTN; Subscriber line protocol over the local loop for display (and related) services; Part 1: On-hook data transmission
• CCITT Recommendation I.130: Method for the characterization of telecommunication services supported by an ISDN and network capabilities

SIST ETS 300 648 E1:2004 strengthens interoperability and user experience in telephony systems by standardizing how calling line information is handled and presented within the PSTN infrastructure. Network operators, device manufacturers, and service providers rely on this standard to deliver consistent, reliable caller ID services.

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 [3], the following three level structure is used to
describe supplementary telecommunications services for the 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.
The principle of this three level structure has been used to develop the service description for the Calling
Line Identification Presentation (CLIP) supplementary service as provided by European public
telecommunication operators for the Public Switched Telephone Network (PSTN).
This ETS details the stage 1 aspects (overall service description) for the CLIP supplementary service for
the PSTN.
ETS 300 659-1 [5] specifies the subscriber line protocol for various PSTN display services at terminal
equipment in the "on-hook" state and this includes the protocol for the CLIP supplementary service.

1 Scope
This European Telecommunication Standard (ETS) defines the stage one of the Calling Line Identification
Presentation (CLIP) supplementary service for the Public Switched Telephone Network (PSTN) as
provided by European public network operators. Stage one is an overall service description from the
user's point of view (see CCITT Recommendation I.130 [3]), but does not deal with the details of the
human interface itself.
This ETS defines the interworking requirements between PSTNs and private networks, PSTNs and
Integrated Services Digital Networks (ISDNs), and Public Land Mobile Networks (PLMNs).
