ATA - Answer a call

The GSM module does not automatically answer calls after you switch on your com- puter. In accordance with the factory configuration, it does not go off-hook. The ATA command causes your GSM module to go off-hook when the phone rings. You deter- mine whether or not you wish to answer.

ATS0=n - Auto-answer mode

The ATS0=n command allows you to configure your GSM module so that it will auto- matically answer calls. "n" represents the number of ringing signals before the call is answered. Permissible values are from "0" to "5".

ATS0=0

No auto-answer: incoming calls are ignored.

 

 

 

 

ATS0=1

The GSM module goes off-hook after the first ringing signal.

ATS0=5

The GSM module goes off-hook after the fifth ringing signal.

 

 

 

 

You can use the ATA command to answer calls at any time, regardless of these set- tings.

Displaying and storing a configuration

The GSM module works with a set of parameters that determine its functioning. This set of parameters is called the active configuration profile. Values for these parameters are predefined in a factory configuration that you can use at any time when you load it using the AT&F command. The GSM Module M1 allows you to modify the active con- figuration profile by means of AT or S-register commands. These options will be de- scribed in subsequent sections. When you switch off the GSM module, any changes you made to the active configuration profile are lost. When you switch it on again, the active configuration profile once again corresponds to the factory configuration. How- ever, the GSM module has two nonvolatile memory blocks in which you can store con- figuration profiles (AT&Wn command, page 29). These blocks are user profiles "0" and "1". When you switch on your system, the GSM module loads the user profile that you set by means of the AT&Yn command. For more information, see the section entitled “AT&Yn - Configuration at power-up”.

Please note:

When the module is supplied, both user memories contain the factory profile.

M1 specifications

The Siemens M1 is a prominent urban transit solution designed for efficient and sustainable public transportation systems. This innovative metro train has become a staple in various metropolitan areas, known for its balance of performance, safety, and passenger comfort.

One of the key features of the Siemens M1 is its modular design, which allows for flexibility in configuration depending on specific transit needs. The train typically consists of multiple carriages that can be adjusted for length and capacity, accommodating different passenger volumes while minimizing operational costs. This adaptability makes the M1 ideal for growing urban environments where ridership numbers can fluctuate.

The Siemens M1 is built with advanced technologies that enhance its operational efficiency. It utilizes a lightweight construction, primarily through the use of aluminum, which reduces energy consumption while still maintaining structural integrity and safety standards. The train is also equipped with cutting-edge traction systems that ensure smooth acceleration and fast braking, resulting in a comfortable ride for passengers.

Safety is a paramount concern in transit systems, and the M1 incorporates various safety technologies. It features advanced signaling systems that enhance communication between trains and trackside equipment. Moreover, the train is designed with anti-collision measures and real-time monitoring systems that can detect faults before they lead to service disruptions.

Passenger comfort is another critical aspect of the Siemens M1 design. The interiors are spacious and feature modern seating arrangements, allowing for easy movement within the train. Large windows provide natural light and views of the outside environment, contributing to a more pleasant travel experience. The train also offers features like climate control, information displays, and accessibility options for passengers with reduced mobility.

Environmental sustainability is an integral part of the Siemens M1’s design. It is tailored to reduce carbon emissions, featuring energy-efficient systems that lower the overall ecological footprint. Additionally, the train can be integrated with renewable energy sources, further promoting green public transport initiatives.

Overall, the Siemens M1 stands out as a versatile and efficient urban transit option, combining modern technology and design principles that cater to the needs of both operators and passengers. With its focus on safety, comfort, and sustainability, the Siemens M1 continues to play a vital role in shaping the future of urban mobility.
