Remote-SAT User's Guide

1.4.4 AT^SSTGI Remote-SAT Get Information – Setup Call (16)

Write command

AT^SSTGI=16

This command is to be used upon receiving an unsolicited result code ^SSTN:16.

If the SIM Application attempts to set up a call it uses this response to inform the TA of the call parameters.

The sequence of events is as follows:

1.After the Remote-SAT notification 16 was issued the TA has to ask for the command parameter via AT^SSTGI=16.

2.If the SIM Application supplies no confirmation text or icon parameter, the TA gives other information to the user, e.g. the telephone number. In this case flow continues at step 4.

3.If the SIM Application supplies a non empty confirmation text or icon parameter, the TA uses only these to ask the user whether or not he wishes to set up the call.

4.If the user confirms to set up the call, AT^SSTR=16,0 shall be responded.

5.If the user denies to set up the call, AT^SSTR=16,34 shall be responded.

6.After confirmation phase the TA may present a dialling animation on the screen until a mandatory parameter line

^SSTR: 16, <TermQualifier>, <TerminationCauseText> is issued.

7.If <TermQualifier> is not equal to 0 the dialling process did not perform successfully.

If <TerminationCauseText> is not an empty string, this text has to be shown to the user for an appropriate time, e.g. 2 seconds. The text contains information regarding the dial termination cause, e.g. call barring through Call Control by SIM mechanism.

<TerminationCauseText> is an empty string, the TA shall give an own indication to the user.

8.If <TermQualifier> is equal to 0, the dial process has been successfully finished:

If <TerminationCauseText> is not an empty string, this text shall be used to inform the user during the call setup.

If <TerminationCauseText> is an empty string, <callSetupText> and/or <confirmationIconId> shall be used to inform the user during call setup. However, if <callSetupText> contains no data, too, no indication shall be shown.

9.The TA shall give the user an opportunity to end an ongoing call, set up by the Proactive Command. In this case the TA shall issue an ATH command to the ME.

Response

^SSTGI: <cmdType>, <commandDetails>, <confirmationText>, <calledNumber>, <callSetupText>, <confirmationIconQualifier>, <confirmationIconId>, <callSetupIconQualifier>,<callSetupIconId> <CR> <LF>

Parameters

 

<cmdType>

16 – Proactive command ID, see Table 1

<commandDetails>

This byte is RFU.

<confirmationText>

String for user confirmation stage

<calledNumber>

String containing called number

<callSetupText>

String for call setup stage

<confirmationIconQualifier> Unsigned Integer, range 0 – 255, used as a bitfield.

bit 1: 0 = icon is self explanatory and replaces text

MC35 specifications

The Siemens MC35 is a compact and versatile modem designed primarily for mobile communication, data transmission, and machine-to-machine (M2M) applications. Launched in the early 2000s, it quickly became popular due to its blend of performance, reliability, and ease of integration, making it a solid choice for developers and businesses.

One of the key features of the MC35 is its support for GSM and GPRS technologies. This allows it to connect seamlessly to various networks, enabling users to transmit data at speeds that were impressive for its time. The GPRS capability can offer data rates of up to 171.2 kbps, allowing for efficient data transfer even in areas with limited connectivity.

The MC35 is designed to support both SMS and voice functionalities, making it adaptable for a range of applications. This includes remote monitoring, telemetry, and alarm signaling. The ability to send and receive SMS messages is a significant advantage for applications that require immediate alerts and notifications, enhancing its utility in security systems and industrial automation.

Furthermore, the modem is equipped with a range of interfaces, including serial communication (RS232), which makes it compatible with various hardware devices. This facilitates easy integration into existing systems, whether for industrial machinery or consumer electronics. Additionally, it features a robust software development kit (SDK), which enables developers to create custom applications tailored to their specific requirements.

Power consumption is another notable characteristic of the Siemens MC35. It is engineered to be energy-efficient, which is especially important for battery-operated devices or systems that require a prolonged operation without frequent recharging or maintenance.

In terms of physical characteristics, the MC35 is compact and lightweight, allowing it to fit into various enclosure designs without occupying much space. Its durability ensures it can perform reliably in different environments, making it suitable for outdoor and industrial applications.

To summarize, the Siemens MC35 stands out as a reliable modem with a rich feature set that includes GSM and GPRS support, SMS and voice capabilities, easy integration through various interface options, and energy-efficient operation. Its adaptability makes it a valuable tool for a wide array of communication and data transmission tasks, solidifying its place in the evolution of mobile communications technology.
