Chapter 1 – AT Commands for Remote SIM Application Toolkit

Multi-Tech Systems, Inc. SIM Application Toolkit AT Commands (S000391C) 14

1.1.10.4 Envelope Command Sequence (Call / MO / SMS Control)

Envelope commands are issued for Call/MO control by the SAT if Call control is enabled. Upon receiving the

response from the SIM application, SAT changes to the PAC state.

In the PAC state, the TA is informed of the pending information and expected to issue AT^SSTGI to request

further information. This sends SAT into the WAIT state upon which it sends the relevant Call/MO Control

information to the TA.

SAT then returns to its IDLE state.
