7.3.2 Transportation of a APDU using T = 1 p. 54

7.3.2.0 General mechanism p. 54

A C-APDU is sent from the application layer of the terminal to the transport layer of the terminal. The transport layer maps the C-APDU onto the INF of an I-block without change. The I-block is sent to the UICC. The Response data (if present) and the status are returned from the UICC to the transport layer of the terminal in the INF of an I-block. If the UICC returns a status which indicates:

a warning ('62XX' or '63XX');
an application condition ('9XXX'); or
a successful execution of the command ('9000');

then it shall also return data (if available) associated with the processing of the command. No data shall be returned with any other status.

The contents of the INF of the I-block are mapped onto the R-APDU without change and returned to the application layer of the terminal. The transportation of APDU messages with T = 1 is mapped to the information of an I-block according to the four different cases described below. Each case is described in detail in clauses 7.3.2.1 to 7.3.2.4.

If the UICC indicates in the ATR both support of LSIs and in the response to MANAGE LSI(configure LSIs) support for LSI selection using the NAD byte, the NAD byte may be used to select the LSI. If the NAD byte is used to select the LSI, the transmission of an APDU (starting with the first I-block of the C-APDU and ending with the last I-block of the R-APDU) on one LSI shall not be interleaved with any block of a different LSI.

7.3.2.1 Case 1 p. 55

C-APDU is mapped to the INF of the I-block without any changes.

Reproduction of ETSI TS 31.ETSI-102-221, Fig. 7.10:

Figure 7.10

The response received from the INF in the I-block is mapped unchanged to the R-APDU.

7.3.2.2 Case 2 p. 55

The C-APDU is mapped to the INF of an I-block without any changes.

Reproduction of ETSI TS 31.ETSI-102-221, Fig. 7.11:

Figure 7.11

The R-APDU consists of either the INF of the I-block or the concatenation of the INF of successive I-blocks all received in the same response, which all shall be chained.

7.3.2.3 Case 3 p. 55

The C-APDU is mapped without any changes to either an INF or is concatenated onto several successive I-blocks, which all shall be chained.

Reproduction of ETSI TS 31.ETSI-102-221, Fig. 7.12:

Figure 7.12

The INF of the I-block is mapped to the R-APDU without any changes.

7.3.2.4 Case 4 p. 55

The C-APDU is mapped without any changes to either an INF or is concatenated onto several successive I-blocks, which all shall be chained.

Reproduction of ETSI TS 31.ETSI-102-221, Fig. 7.13:

Figure 7.13

The response consists of either the INF of an I-block received in the response or the concatenation of INF of successive I-blocks in response, which all shall be chained.
