Chapter 1 – AT Commands for Remote SIM Application Toolkit
Multi-Tech Systems, Inc. SIM Application Toolkit AT Commands (S000391C) 12
1.1.10.2 Proactive Command Sequence
After receiving a proactive command (PAC) from the SIM, SAT enters the PAC state. The TA is informed
that a PAC has been issued and is expected to respond with a request for further information. While in the
PAC state, some forms of the AT^SSTR commands can be issued.
Upon receiving the AT^SSTGI command, SAT changes to the WAIT state. Further information about the
PAC are sent to the TA and a response is required to trigger a TERMINAL RESPONSE back to the SIM
Application.
SAT returns to the IDLE state and either another PAC is issued or the SAT informs the TA that the proactive
session has been terminated.
