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.

(GSM 11.19 version 7.0.3 Release 1998)
The CTS-SN sends a Random Number (RAND) to the CTS-FPE. The CTS-FPE passes the RAND to the FP-SIM in the
command RUN GSM ALGORITHM. The FP-SIM returns the Kop value to the CTS-FPE which are derived using the
algorithms and processes given below. Then the CTS-FPE performs the authentication using Kop and a fixed value to
generate the signature SRES. CTS-FPE sends SRES to the network. The fixed network compares this value with the
value of SRES which it calculates by itself. The comparison of these SRES values provides the authentication.
A subscriber authentication key Ki is used in this procedure. This key Ki has a length of 128 bits and is stored
FP FP
within the FP-SIM in the same way Ki is used in the SIM card for GSM authentication.
4.4.2 Algorithms and processes
The names and parameters of the algorithms supported by the FP-SIM are defined in GSM 03.20, Annex E [5]. These
are:
- Algorithm A3 to generate the first part of the key Kop (Kop1);
- Algorithm A8 to generate the second part of the key Kop (Kop2).
These algorithms may exist either discretely or combined (into A38) within the FP-SIM. In either case the output on the
FP-SIM/CTS-FPE interface is 12 bytes. The inputs to both A3 and A8, or A38, are Ki (128 bits) internally derived in
FP
the FP-SIM, and RAND (128 bits) across the FP-SIM/CTS-FPE interface. The output is the concatenation of Kop1
(32 bits)/Kop2 (64 bits) to produce Kop the coding of which is defined in the command RUN GSM ALGORITHM in
subclause 4.6.1.
4.5 Description of the functions
GSM 11.11 [12] applies with the following additional specification.
4.5.1 RUN GSM ALGORITHM
This function is used during the procedure for authenticating the CTS-FPE to a CTS-SN and to calculate a cipher key.
The card runs the specified algorithms A3 and A8 using a 16 byte random number and the subscriber authentication key
Ki , which is stored in the FP-SIM. The function returns the key Kop.
FP
The function shall not be executable unless DF or any sub-directory under DF has been selected as the
FP CTS FP CTS
Current Directory. The CHV1 shall be always disabled.
Input:
- RAND.
Output:
- Kop.

4.7 Contents of the Elementary Files (EF)
This clause specifies the EFs for the CTS session defining access conditions, data items and coding. A data item is a
part of an EF which represents a complete logical entity.
EFs or data items having an unassigned value, or, which during the CTS session, are cleared by the CTS-FPE, shall
have their bytes set to 'FF'. After the administrative phase all data items shall have a defined value or have their bytes
set to 'FF'. If a data item is 'deleted' during a CTS session by the allocation of a value specified in another CTS-TS, then
this value shall be used, and the data item is not unassigned.
EFs are mandatory (M) or optional (O). The file size of an optional EF may be zero. All implemented EFs with a file
size greater than zero shall contain all mandatory data items. Optional data items may either be filled with 'F', or, if
located at the end of an EF, need not exist.
For an overview containing all files see figure 1.

Other values are RFU.
If the CTS phase is coded '03' or greater, a CTS-FPE supporting SIM Application Toolkit shall perform the PROFILE
DOWNLOAD procedure, as defined in GSM 11.14 [13].
Coding:
2 bits are used to code each service:
first bit = 1: service allocated
first bit = 0: service not allocated
where the first bit is b1, b3, b5 or b7;
second bit = 1: service activated
second bit = 0: service not activated
where the second bit is b2, b4, b6 or b8.
Service allocated means that the FP-SIM has the capability to support the service. Service activated means that
the service is available for the card holder (only valid if the service is allocated).
The following codings are possible:
- first bit = 0: service not allocated, second bit has no meaning;
- first bit = 1 and second bit = 0: service allocated but not activated;
- first bit = 1 and second bit = 1: service allocated and activated.
The bits for services not yet defined shall be set to RFU. For coding of RFU see subclause 7.3.

- Length of CTS service number
Contents:
this byte gives the number of bytes of the following two data items containing actual BCD number
information. This means that the maximum value is 11, even when the actual CTS-SN information length is
greater than 11. When a CTS-SN has extension, it is indicated by the extension1 identifier being unequal to
'FF'. The remainder is stored in the EF with the remaining length of the additional data being coded
CTS-EXT
in the appropriate additional record itself. (see TS-GSM11.11 [12]).
Coding:
according to GSM 04.08 [7].
-TONandNPI
Contents:
Type of number (TON) and numbering plan identification (NPI).
Coding:
according to GSM 04.08 [7].
