scope:
This European Telecommunication Standard (ETS) defines the GSM Application Programming Interface (GSM-API) in two parts.
The first part describes, how compatibility to existing application interface ETS 300 838 [14] is covered for the GSM network. So existing PCI applications are able to be used in a GSM environment. For these applications the necessary mapping and local knowledge between application interface and network is described. The only modifications needed in ETS 300 838 [14] to fulfil this requirements are covered by changes of the parameter description. These changes of parameters are defined in clauses 4 and 5 of this ETS.
An application compliant with this ETS shall not imply compliance with ETS 300 838 (HPCI).
Clause 4 is meant to replace subclause 5.7 message parameters of ETS 300 838 [14]. which defines the parameters of the profile A of the HPCI.
NOTE 1: Clause 4is for further study.
Clause 5 replaces subclause 6.8 parameter description of ETS 300 838, which defines the parameters of the profile B of the HPCI.
The second part defines GSM specific features. New GSM-API applications need extensions to ETS 300 838 [14] which are defined in section 6 and 7of this ETS.
These sections are meant as an addition to ETS 300 838 [14]. They do not replace any clause of ETS 300 838 [14].
Clause 6 defines the extensions according to the profile A of ETS 300 838 [14].
NOTE 2: Clause 6 is for further study.
Clause 7 defines the extensions according to the profile B of ETS 300 838 [14] (bit compatible to COMMON ISDN API).
The messages and the operating system dependent part of ETS 300 838 [14] will not be changed for GSM-API.
