ETSI EN 302 409

The present document defines the aspects of the internal organization of the FP-SIM which are related to the CTS initialization and CTS enrolment operation phase of CTS as well as the files contained in the SIM for dedicated CTS operation . This is to ensure interoperability between a FP-SIM and a CTS-FPE independently of the respective manufacturers and operators. The present document defines: -the contents of the files required for the CTS application; -the application protocol. All information regarding the interface between the Fixed Part Subscriber Identity Module (FP-SIM) and the Cordless Telephony System Fixed Part Equipment (CTS-FPE) mentioned below are fully compliant with the TS-GSM11.11 [12] unless otherwise stated in this present document. -the requirements for the physical characteristics of the FP-SIM, the electrical signals and the transmission protocols; -the model which shall be used as a basis for the design of the logical structure of the FP-SIM; -the security features; -the interface functions; -the commands. For more details regarding CTS, refer to specifications GSM 02.56 [3]and GSM 03.56 [6]. The present document does not specify any aspects related to the administrative management phase. Any internal technical reallocation of either the FP-SIM or the CTS-FPE are only specified where these reflect over the interface. It does not specify any of the security algorithms which may be used.
