<br />

The <strong>TC63i</strong> can operate either as SAP server or as SAP client. A brief description of the configuration is given<br />

below.<br />

SAP server<br />

The SAP server has direct (galvanic) access to a SIM. It acts as a SIM card reader which assists the SAP client<br />

in accessing and controlling this SIM via the serial link.<br />

After RSA activation, the SAP server waits for SAP CONNECTION_REQ messages from the SAP client (see<br />

Figure 15.3, SIM usage states of SAP server). The SAP server still uses its local SIM card until the parameter<br />

negotiation with an SAP client has been accomplished successfully.<br />
