Intellectual Property Rights
IPRs essential or potentially essential to the present document may have been declared to ETSI. The information
pertaining to these essential IPRs, if any, is publicly available for ETSI members and non-members, and can be found
in SR 000 314: "Intellectual Property Rights (IPRs); Essential, or potentially Essential, IPRs notified to ETSI in respect
of ETSI standards", which is available from the ETSI Secretariat. Latest updates are available on the ETSI Web server
(http://www.etsi.org/ipr).
Pursuant to the ETSI IPR Policy, no investigation, including IPR searches, has been carried out by ETSI. No guarantee
can be given as to the existence of other IPRs not referenced in SR 000 314 (or the updates on the ETSI Web server)
which are, or may be, or may become, essential to the present document.
Foreword
This ETSI Guide (EG) has been produced by ETSI Technical Committee Services and Protocols for Advanced
Networks (SPAN).
Introduction
The tables are intended to record all known assigned addressing codes. Where a particular ETSI member is shown to
have assigned a code or codes this should not be taken to mean that the codes are unavailable for standardization, but to
allow a reasoned choice to be made before assigning codes for new services. In future all newly assigned codes will be
recorded in the present document rather than the relevant ETSI MTP and SCCP specifications. Thus if referenced by
these specifications then the information shall be considered normative.
Some of the SCCP material in the present document is based on ITU-T Recommendation Q.715 [1] which is a very
valuable source of additional information and should be considered as a complement to the present document.

1 Scope
The present document is intended for use by designers of MTP/SCCP applications as well as by network operators
configuring those applications to help facilitate MTP/SCCP interconnect between ETSI member networks.
In addition to information of an advisory nature, all known standardized SCCP message address codes and MTP SI
codes are also listed.

4 SCCP address code allocations
In general the rules of ITU-T Recommendation Q.713 [2] should apply to ensure ease of interworking SCCP between
both ETSI and non-ETSI-member networks. Addressing codes not standardized within ITU-T may be exchanged
subject to agreement of all concerned operators. Address codes for the support of services not standardized in ITU-T but
agreed within ETSI are recorded in the present document in a similar way to ITU-T Recommendation Q.713 [2],
annex B, where appropriate.
