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.
