Atsacm Advice of charge and query of ACM and ACMmax

AT Command Set

8.4AT^SACM Advice of charge and query of ACM and ACMmax

Test command	Response
AT^SACM=?	^SACM: (list of supported <n>s) OK
	Parameter
	See write command

Execute command

AT^SACM

The execute command can be used to query the current mode of the Advice of Charge supplementary service, the SIM values of the accumulated call meter (ACM) and accumulated call meter maximum (ACMmax).

Response

^SACM: <n>,<acm>,<acm_max> OK

If error is related to ME functionality:

+CME ERROR: <err>

Parameter
<n>	See write command
<acm>	ACM, string type; three bytes of the current ACM value in hexadeci-
	mal format (e.g. “00001E” indicates decimal value 30) 000000–
	FFFFFF

<acm_max> ACMmax, string type; three bytes of the max. ACM value in hexade- cimal format (e.g. “00001E” indicates decimal value 30) 000000 dis- able ACMmax feature 000001-FFFFFF

<ccm> string type; three bytes of the current CCM value in hexadecimal for- mat (e.g. “00001E” indicates decimal value 30); bytes are coded in the same way as ACMmax value in the SIM 000000-FFFFFF

Write command

AT^SACM=<n>

The write command enables or disables the presentation of unsolicited result to report the call charges.

Response

OK or if error is related to ME functionality: +CME ERROR: <err>

Parameter
<n>	0	suppress unsolicited result code
	1	display unsolicited result code

When you power down or reset the ME with AT+CFUN=1,1 the URC presentation mode will be reset to its default. To benefit from the URC it is recommended to have the setting included in the user pro- file saved with AT&W, or to select <n>=1 every time you reboot the ME.

Unsolicited result code

When activated, an unsolicited result code is sent when the CCM value changes, but not more often than every 10 seconds

+CCCM: <ccm>

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.
