GSM routers often are called active modems. Such devices are used to provide data for the VoIP GSM communication via basic protocols, including TCP/IP.
The GSM router helps carry out sending and receiving of SMS-messages. Many routers have an SMS emergency message function that transmits information without entering specific AT commands. This function is very easy to set up and allows the channel to instantly transmit data. Restrictions apply to the size of messages only.
For this reason, the owners of the consulting companies and service centers must remember that when you send a long SMS, a properly tuned seven-bit encoding is used. Incorrect installation of equipment and the simultaneous transmission of big packages can cause the system to freeze and suspend. As a rule, when you apply a correct configuration during packages are delivered in less than eight seconds, while in the case of errors - delays, freezes or even the loss of messages are guaranteed.
From this perspective, it is recommended to explore all capabilities of a GSM router before it is connected. An important part of the device coordination is the integrated system of statistics and error checking, which allows the best use of it. When you do the diagnosis, occurred problems become immediately visible. And all data is archived and recorded on the memory card, so you can view, analyze and export it.
In addition, the device can be controlled remotely via computer, by connecting VoIP to the system. For a more effective communication users install GSM gateway, which is set up under the office needs.
To enjoy high-quality communication with subscribers, other devices like expansion modules with outputs for analog devices are connected to the gateways, while the GSM-routers should be connected to the server.
