Foreword
This European Telecommunication Standard (ETS) has been produced by the Special Mobile Group
(SMG) Technical Committee (TC) of the European Telecommunications Standards Institute (ETSI).
This ETS defines the connection types for the GSM Public Land Mobile Network (PLMN). This ETS
corresponds to GSM Technical Specification (GSM-TS) GSM 03.10 version 4.3.1.
The specification from which this ETS has been derived was originally based on CEPT documentation,
hence the presentation of this ETS may not be entirely in accordance with the ETSI/PNE rules.
Reference is made within this ETS to GSM-TSs (NOTE).
Reference is also made within this ETS to GSM xx.xx. series. The specifications in the series can be
identified, with their full title, within the normative reference Clause of this `ETS by the first two digits of
their GSM reference number e.g. GSM 09.xx series, refers to GSM 09.01, GSM 09.02, etc.
NOTE: TC-SMG has produced documents which give the technical specifications for the
implementation of the European digital cellular telecommunications system. Historically,
these documents have been identified as GSM Technical Specifications (GSM-TSs).
These TSs may have subsequently become I-ETSs (Phase 1), or ETSs (Phase 2),
whilst others may become ETSI Technical Reports (ETRs). GSM-TSs are, for editorial
reasons, still referred to in current GSM ETSs.

0 Scope
A GSM PLMN may be described by a limited set of access interfaces (refer to TS GSM 04.02 and 02.01)
and a limited set of GSM PLMN connection types to support the telecommunication services described in
the GSM 02-series of specifications. This specification identifies and defines these connection types in so
far as they relate to the particular network capabilities for a GSM PLMN.
The basic lower layer capabilities of a GSM PLMN are represented by a set of GSM PLMN connection
types. The definition of a set of GSM PLMN connection types provides the necessary input to identify
network capabilities of a GSM PLMN. In addition to describing network capabilities of a GSM PLMN, the
identification of connection types facilitates the specification of network-to-network interfaces. It may also
assist in the allocation of network performance parameters.
This specification should be considered in conjunction with other GSM specifications with particular
reference to TS GSM 01.02, 02.01, 02.02, 02.03, 03.01, 03.02, 04.02 and 04.03.
This specification provides a bridge between the service specification in the GSM 02-series of specification
and the more detailed specifications such as TS GSM of the 03, 04, 07 and 09 series. As such, it
establishes a framework for the specification and understanding of the more detailed specifications. It is
therefore not a specification against which detailed conformance testing can be performed. However, it
shall be considered mandatory for the understanding of the more detailed specifications and used to
resolve issues of conflict in these specifications.
1 Definitions
(Digital) connection:
A concatenation of (digital) transmission channels or (digital) telecommunication circuits, switching and
other functional units set up to provide for the transfer of (digital) signals between two or more points in a
telecommunication network to support a single communication.
GSM PLMN connection:
A connection that is established through a GSM PLMN between specified GSM PLMN reference points.
GSM PLMN connection type:
A description of a set of GSM PLMN connections which have the same characteristics.
