SSH ETS 300 904:1997 ed.1

Digital cellular telecommunications system (Phase 2+) (GSM); Bearer Services (BS) supported by a GSM Public Land Mobile Network (PLMN) (GSM 02.02 version 5.2.1)

Scope

This European Telecommunication Standard (ETS) defines a set of Bearer Services to be provided to GSM PLMN subscribers by a GSM PLMN itself and in connection with other networks. This ETS should also be used as a reference for defining the corresponding required mobile network capabilities which are specified by means of the "GSM PLMN connection type" concept, defined in GSM 03.10 [4]. The recommended provision of the Bearer Services is under the control of the GSM MoU and is out of the scope of ETSI TC-SMG. Bearer Services not included in this ETS that require modifications to the GSM signalling specifications should not be introduced unilaterally by a mobile network operator.
