Foreword
This European Telecommunication Standard (ETS) has been produced by the European Computer
Manufacturers Association (ECMA) on behalf of its members and those of the European
Telecommunications Standards Institute (ETSI).
This ETS is based on the ISDN concept as developed by CCITT and refined by ETSI for European
applications, but modified to cover the particularities of private telecommunication networks. It is also in
the framework of standards for Open Systems Interconnection as defined by ISO 7498.
The Protocol specified in this ETS is an application to the S reference point of the corresponding aspects
of Digital Subscriber Signalling System No. one (DSS1).
This ETS was produced by ECMA using the ECMA guidelines for the production of standards and using
the ECMA stylesheet. In order to avoid undue delays in the publication of this ETS it has been agreed that
this ETS will not be converted to the ETSI stylesheet.

1 Scope
This standard specifies the signalling protocol for the support of identification supplementary services at
an interface at the S reference point between a Terminal Equipment (TE) and a Private
Telecommunication Network (PTN). The Protocol specified in this standard is an extension of the layer 3
protocol for the support of circuit mode basic services, as specified in ETS 300 192. The identification
supplementary services concerned are Supplementary Service Calling Line Identification Presentation
(SS-CLIP), Supplementary Service Connected Line Identification Presentation (SS-COLP) and
Supplementary Service Calling / Connected Line Identification Restriction (SS-CLIR).
Service specifications are produced in three stages, according to the method specified in ENV 41005.
This standard satisfies the requirements identified by the stage 1 and stage 2 specifications in ETS
300 173. This standard is applicable to user accesses of PTNXs and to TEs which are intended for
connection to PTNs.
The impact on the protocol of interactions between the supplementary services specified in this standard
and other supplementary services is outside the scope of this standard.
2 Conformance
In order to conform to this standard, a PTNX shall satisfy the requirements identified in the Protocol
Implementation Conformance Statement (PICS) Proforma in Clause B.3 of Annex B.
In order to conform to this standard, a TE shall satisfy the requirements identified in the Protocol
Implementation Conformance Statement (PICS) Proforma in Clause B.4 of Annex B.

6 Signalling Protocol for the support of SS-CLIP
6.1 SS-CLIP Description
Calling Line Identification Presentation (SS-CLIP) is a supplementary service which is offered to the called
user and which provides the calling user's number, and subaddress if available, to the called user.
The PTN provides the called user with the number of the calling user whenever an incoming call is
presented. The number provided should be sufficient to enable the called user to return the call.
The calling user's number may be accompanied by a subaddress.
6.2 SS-CLIP Operational Requirements
6.2.1 Provision/Withdrawal
SS-CLIP shall be available to all PTN users with the ability to receive this information. There is no need for
service profile control.
Some PTN users may be given a service profile which permits the override of calling line identification
restriction.
6.2.2 Requirements on the Originating Network Side
There are no special requirements for SS-CLIP beyond the basic call procedures specified in ETS
300 192.
NOTE 1:
As part of basic call procedures at the Originating TE-PTN interface, the TE may supply the calling user's
number and/or the calling user's subaddress to the PTN. The PTN can use this information to derive the
information needed to provide SS-CLIP at the Destination TE-PTN interface (see ETS 300 189).
6.2.3 Requirements on the Destination Network Side
The special requirements detailed in subclause 6.5 for SS-CLIP are in addition to the basic call
procedures specified in ETS 300 192.
6.3 SS-CLIP Coding Requirements
The Calling party number information element shall be encoded as specified in ETS 300 192, subclause
12.5.10. This information element can occur in the SETUP message in the direction PTN to TE for the
support of SS-CLIP.
The Calling party subaddress information element shall be encoded as specified in ETS 300 192,
subclause 12.5.11. This information element can occur in the SETUP message in the direction PTN to TE
for the support of SS-CLIP.

6.5.4.1 Normal Procedures
NOTE 2:
The text of this subclause is based upon that of subclause 9.5.1 of ETS 300 092. Differences are indicated
by emboldening.
When a SETUP message is sent to the called TE according to the procedures of ETS 300 192, the
PTN shall check to see if the Calling user's number is available.
If the calling user's number is available and presentation is allowed according to the presentation indicator
supplied together with the calling user's number, the PTN shall include the Calling party number
information element in the SETUP message sent to the called TE. If available, the PTN shall also include
the Calling party subaddress information element in the SETUP message. The presentation and
screening indicators associated with the calling user's number received at the Destination PTNX shall be
passed transparently to the called TE. Values for use in the numbering plan identifier and type of
number fields shall be in accordance with ETS 300 189.
If the calling user's number is available, but presentation is not allowed according to the presentation
indicator supplied together with the calling user's number, the PTN shall include the Calling party number
information element in the SETUP message sent to the called TE. The presentation indicator in the
Calling party number information element shall indicate "presentation restricted". The screening
indicator shall indicate "network provided". The type of number and the numbering plan identification
shall be set to "unknown" and the number digits field shall not be included. The PTN shall include the
Calling party subaddress information element, if available, in the SETUP message.
If the calling user's number is not available at the destination PTNX the PTN shall include the Calling
party number information element in the SETUP message sent to the called TE. The presentation
indicator shall be set to "number not available due to interworking" or "presentation restricted", according
to information available, the screening indicator shall be set to "network provided", the type of number and
the numbering plan identification shall be set to "unknown" and the number digits field shall not be
included. The PTN shall include the Calling party subaddress information element, if available, in the
SETUP message.
If presentation is restricted but the called PTN user has the override category (e.g., police or emergency
service) marked in the Destination PTNX, the PTN shall include the Calling party number information
element, and Calling party subaddress information element if the subaddress was supplied by the calling
PTN user, in the SETUP message. In this case, the presentation and screening indicators shall be passed
transparently to the called TE. Values for the use in the numbering plan identifier and type of number
fields shall be in accordance with ETS 300 189.

NOTE 3:
The Specification and Description Language (SDL) representation of the procedures at the Destination
PTNX is contained in Clause C.1 of Annex C.
6.5.4.2 Exceptional Procedures
Not applicable.
6.5.5 Actions at the Destination TE
The use of the Calling party number and Calling party subaddress information elements, if present in a
received SETUP message, is an implementation matter.
NOTE 4:
If the presentation indicator in the Calling party number information element is set to "number not available
due to interworking" or "presentation restricted", the remaining information in octets 3 and 3a of the Calling
party number information element should be ignored, except where, in the context of the override
category, number information in octet 4 has been provided.
6.6 SS-CLIP Impact of Interworking with Public ISDNs
The procedures specified in subclause 6.5 shall be used.
NOTE 5:
In addition to other factors, the availability of the calling user's number and subaddress from the public
ISDN will depend upon subscription to the public ISDN's SS-CLIP.
NOTE 6:
Some public ISDNs may provide two calling user numbers in some circumstances. The first of these
numbers (i.e. the one appearing in the first Calling party number information element in the SETUP
message received from the public ISDN) will be used for the provision of SS-CLIP to the called user.
NOTE 7:
On outgoing calls to a public ISDN, the provision of the calling user's DDI number to the public ISDN can
assist in the provision of SS-CLIP to the called user.
6.7 SS-CLIP Impact of Interworking with Non-ISDNs
The procedures specified in subclause 6.5 shall be used.
NOTE 8:
Some non-ISDNs are unable to provide the calling user's number and subaddress.
NOTE 9:
Some non-ISDNs can provide the calling user's number but without any indication of whether presentation
is restricted. Whether the PTN presents such numbers to the called user is an implementation matter.
6.8 SS-CLIP Parameter Values (Timers)
No specific timers are required.
7 Signalling Protocol for the support of SS-COLP
7.1 SS-COLP Description
Connected Line Identification Presentation (SS-COLP) is a supplementary service which is offered to the
calling user and which provides the connected user's number, and subaddress if available, to the calling
user.
The PTN provides the calling user with the number of the connected user when that user connects to the
incoming call (connected user identification). The number provided should be sufficient to reach the same
user again.

The connected user's number may be accompanied by a subaddress.
7.2 SS-COLP Operational Requirements
7.2.1 Provision/Withdrawal
SS-COLP shall be available to all PTN users with the ability to receive this information. There is no need
for service profile control.
Some PTN users may be given a service profile which permits the override of connected line identification
restriction.
7.2.2 Requirements on the Originating Network Side
The special requirements detailed in subclause 7.5 for SS-COLP are in addition to the basic call
procedures specified in ETS 300 192.
7.2.3 Requirements on the Destination Network Side
There are no special requirements for SS-COLP beyond the basic call procedures specified in ETS
300 192.
NOTE 10:
As part of basic call procedures at the destination TE-PTN interface, the TE may supply a connected
number and/or connected subaddress to the PTN. The PTN can use this information to derive the
information needed to provide SS-COLP at the originating TE-PTN interface (see ETS 300 189).
7.3 SS-COLP Coding Requirements
The Connected number information element shall be encoded as specified in ETS 300 192, subclause
12.5.14. This information element can occur in the CONNECT message in the direction PTN to TE for the
support of SS-COLP.
The Connected subaddress information element shall be encoded as specified in ETS 300 192,
subclause 12.5.15. This information element can occur in the CONNECT message in the direction PTN to
TE for the support of SS-COLP.
