AC75 AT Command Set

s

 

The AC75 can operate either as SAP server or as SAP client. A brief description of the configuration is given below.

SAP server

The SAP server has direct (galvanic) access to a SIM. It acts as a SIM card reader which assists the SAP client in accessing and controlling this SIM via the serial link.

After RSA activation, the SAP server waits for SAP CONNECTION_REQ messages from the SAP client (see Figure 15.3, SIM usage states of SAP server). The SAP server still uses its local SIM card until the parameter negotiation with an SAP client has been accomplished successfully.
