Foreword
This European Telecommunication Standard (ETS) has been produced by the Signalling Protocols and
Switching (SPS) Technical Committee of the European Telecommunications Standards Institute (ETSI).
This ETS is part 1 of a multi-part standard covering the Digital Subscriber Signalling System No. one
(DSS1) protocol specification for the Integrated Services Digital Network (ISDN) Calling Line Identification
Presentation (CLIP) supplementary service, as described below:
Part 1: "Protocol specification";
Part 2: "Protocol Implementation Conformance Statement (PICS) proforma specification";
Part 3: "Test Suite Structure and Test Purposes (TSS&TP) specification for the user";
Part 4: "Abstract Test Suite (ATS) and partial Protocol Implementation eXtra Information for Testing
(PIXIT) proforma specification for the user";
Part 5: "TSS&TP specification for the network";
Part 6: "ATS and partial PIXIT proforma specification for the network".
In accordance with CCITT Recommendation I.130, 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 standard details the stage three aspects (signalling system protocols and switching functions) needed
to support the Calling Line Identification Presentation (CLIP) supplementary service. The stage 1 and
stage 2 aspects are detailed in ETS 300 089 (1992) and ETS 300 091 (1992), respectively.
This reprint includes all previous Corrigenda as shown in the History box at the last page.

1 Scope
This first part of ETS 300 092 specifies the stage three of the Calling Line Identification Presentation
(CLIP) supplementary service for the pan-European Integrated Services Digital Network (ISDN) as
provided by European public telecommunications operators at the T reference point or coincident S and T
reference point (as defined in CCITT Recommendation I.411 [1]) by means of the Digital Subscriber
Signalling System No. one (DSS1) protocol. Stage three identifies the protocol procedures and switching
functions needed to support a telecommunication service (see CCITT Recommendation I.130 [2]).
In addition this standard specifies the protocol requirements at the T reference point where the service is
provided to the user via a private ISDN.
This standard does not specify the additional protocol requirements where the service is provided to the
user via a telecommunications network that is not an ISDN.
The CLIP supplementary service provides the called party with the possibility to receive identification of the
calling party, and is applicable to all telecommunication services.
Further parts of this standard specify the method of testing required to identify conformance to this
standard.
This standard is applicable to equipment supporting the CLIP supplementary service, to be attached at
either side of a T reference point or coincident S and T reference point when used as an access to the
public ISDN.
2 Normative references

5 Description
The CLIP supplementary service is a supplementary service offered to the called user. It provides the
calling user's ISDN number, possibly with the calling user's subaddress information, to the called user.
The information provided to the called user shall consist of the ISDN number of the calling user in a form
sufficient to allow the returning of the call (i.e. a subscriber number, a national number or an international
number and optionally a subaddress if provided by the calling user).
6 Operational requirements
6.1 Provision and withdrawal
See ETS 300 089 [9], subclause 6.1.
6.2 Requirements on the originating network side
All information pertaining to the CLIP supplementary service shall be inserted in the SETUP message sent
as part of the basic call procedures according to ETS 300 102-1 [6], Clause 5.
In the case where no information is provided by the calling user (as part of the basic call procedures) the
network shall provide the default number associated with the access (in which the call was generated) in
the originating local exchange.
When the calling number information is provided by the calling user, the network can only verify that the
number is within the set of numbers allocated to that user.
Where a special arrangement exists with the calling user, no verification shall be performed.
6.3 Requirements on the destination network side
See subclause 9.5.

7 Coding requirements
ETS 300 102-1 [6], subclauses 4.5.10 and 4.5.11 give the coding for the calling party number and the
calling party subaddress information elements which are required to support this service.
The purpose of the calling party number information element is to identify the origin of a call.
The purpose of the calling party subaddress information element is to identify a subaddress associated
with the origin of the call.
8 State definitions
No specific state definitions are required.
9 Signalling procedures at the coincident S and T reference point
9.1 Activation, deactivation and registration
Not applicable.
9.2 Actions at the originating user
9.2.1 Normal operation
These procedures shall be provided as part of the basic service and the calling user need not have
subscribed to the CLIP supplementary service.
The numbering plan identifier, to be indicated within the calling party number information element, sent by
the calling user, shall be either "ISDN/telephony numbering plan (CCITT Recommendations E.164 [4] and
E.163 [5])" or "unknown".
NOTE: Either coding may be used and the treatment of both by the network is identical.
Where the calling number included by the calling user is complete, the type of number to be indicated
within the calling party number information element, sent by the calling user, shall be one of the following:
- "subscriber number", in the case where the complete subscriber number is sent;
- "national number", in the case where the complete national number is sent;
- "international number", in the case where the complete international number is sent.
Where a partial calling number is included by the calling user (e.g. to indicate digits specific to the direct
dialling in or the multiple subscriber number supplementary services) the user shall set the type of number
to be indicated within the calling party number information element to "unknown".
9.2.2 Exceptional procedures
Not applicable.

9.3 Actions at the originating local exchange if a special arrangement does not apply
9.3.1 Normal operation
These procedures shall be provided as part of the basic service and the calling user need not have
subscribed to the CLIP supplementary service.
When a SETUP message is received from the calling user, the network shall check to see if the calling
party number and calling party subaddress information elements are included.
If the calling party number information element is received with a coding of the numbering plan identifier
field other than "ISDN/telephony numbering plan (CCITT Recommendations E.164 [4] and E.163 [5])" or
"unknown", then the network shall discard the calling party number information element and process the
call as if that information element was not received.
At the originating side, the network shall set the value of the screening indicator based on the outcome of
the screening of the calling number. The network shall disregard any value of the screening indicator, if
received from the calling user.
If the calling party number information element is included, the network shall perform the screening
function. If the calling number received from the calling user is determined to be correct, the network shall
set the screening indicator to "user-provided, verified and passed".
NOTE: Some networks may accept a full ISDN number in a calling party number information
element with the addition of a prefix or escape digits to the number digits field and the
type of number field set to "unknown".
If the SETUP message does not contain the calling party number information element or the screening
function has determined the provided calling number to be incorrect, the network shall use a default
number associated with the calling user. The network shall set the screening indicator to "network
provided".
In the case where the calling user provides partial calling number information and the number is a valid digit
sequence for the user access arrangement, the network shall complete the number as appropriate. The
network shall set the screening indicator to "user-provided, verified and passed".
NOTE: In some cases the network cannot guarantee that the completed number identifies an
end user.
If the calling party subaddress information element is available, it shall be passed transparently through the
network.
The number digits and the screening indicator, as determined by the procedures above, shall be forwarded
to the destination local exchange, in association with the basic call request.
The presentation indicator, as determined by the procedures of the CLIR supplementary service (see
ETS 300 093-1 [11]), shall be forwarded to the destination local exchange, in association with the basic
call request.
The actions at the originating local exchange are summarised in table 1.

Page 5ETS 300 092-1: March 1992ForewordThis European Telecommunication Standard (ETS) has been produced by the Signalling Protocols andSwitching (SPS) Technical Committee of the European Telecommunications Standards Institute (ETSI).This ETS is part 1 of a multi-part standard covering the Digital Subscriber Signalling System No. one(DSS1) protocol specification for the Integrated Services Digital Network (ISDN) Calling Line IdentificationPresentation (CLIP) supplementary service, as described below:Part 1:"Protocol specification";Part 2:"Protocol Implementation Conformance Statement (PICS) proforma specification";Part 3:"Test Suite Structure and Test Purposes (TSS&TP) specification for the user";Part 4:"Abstract Test Suite (ATS) and partial Protocol Implementation eXtra Information for Testing(PIXIT) proforma specification for the user";Part 5:"TSS&TP specification for the network";Part 6:"ATS and partial PIXIT proforma specification for the network".In accordance with CCITT Recommendation I.130, the following three level structure is used to describethe supplementary telecommunications services as provided by European public telecommunicationsoperators 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 servicedescribed in stage 1; and,-Stage 3: defines the signalling system protocols and switching functions needed to implement theservice described in stage 1.This standard details the stage three aspects (signalling system protocols and switching functions) neededto support the Calling Line Identification Presentation (CLIP) supplementary service. The stage 1 andstage 2 aspects are detailed in ETS 300 089 (1992) and ETS 300 091 (1992), respectively.This reprint includes all previous Corrigenda as shown in the History box at the last page.SIST ETS 300 092-1:1998

Page 7ETS 300 092-1: March 19921ScopeThis first part of ETS 300 092 specifies the stage three of the Calling Line Identification Presentation(CLIP) supplementary service for the pan-European Integrated Services Digital Network (ISDN) asprovided by European public telecommunications operators at the T reference point or coincident S and Treference point (as defined in CCITT Recommendation I.411 [1]) by means of the Digital SubscriberSignalling System No. one (DSS1) protocol. Stage three identifies the protocol procedures and switchingfunctions needed to support a telecommunication service (see CCITT Recommendation I.130 [2]).In addition this standard specifies the protocol requirements at the T reference point where the service isprovided to the user via a private ISDN.This standard does not specify the additional protocol requirements where the service is provided to theuser via a telecommunications network that is not an ISDN.The CLIP supplementary service provides the called party with the possibility to receive identification of thecalling party, and is applicable to all telecommunication services.Further parts of this standard specify the method of testing required to identify conformance to thisstandard.This standard is applicable to equipment supporting the CLIP supplementary service, to be attached ateither side of a T reference point or coincident S and T reference point when used as an access to thepublic ISDN.2Normative referencesThis standard incorporates by dated and undated reference, provisions from other publications. Thesenormative references are cited at the appropriate places in the text and the publications are listedhereafter.

The network shall disregard any value of the screening indicator, ifreceived from the calling user.If the calling party number information element is included, the network shall perform the screeningfunction. If the calling number received from the calling user is determined to be correct, the network shallset the screening indicator to "user-provided, verified and passed".NOTE:Some networks may accept a full ISDN number in a calling party number informationelement with the addition of a prefix or escape digits to the number digits field and thetype of number field set to "unknown".If the SETUP message does not contain the calling party number information element or the screeningfunction has determined the provided calling number to be incorrect, the network shall use a defaultnumber associated with the calling user.
