Modems

The Modems page contains a list of connected modems. Here you can manage existing modems (edit their properties, activate/deactivate commutation, manage access rights, delete modems, etc.) and create new modems.

Any GSM modem connected to the server can be used in the system. It is recommended to use a modem connected via COM port. If this is USB modem, you will likely have to install a driver for it.

Modems

Some additional variables for modems are set in the configuration file.

To add a new modem, push Create Modem button. Modem properties dialog has several tabs: General, Notifications, SMS Replies, and Billing Plans.

Modem Properties

General

  • Name: enter a name for the modem.
  • Phone number: enter phone number of SIM card installed on the modem.
  • Link priority: define communications channel priority.
  • Restart interval: indicate restart interval as needed (zero is not recommended). If the connection with modem is broken by any reason, after the time it will be automatically restarted. Besides, if the restart interval is zero, the modem is not started when restarting the service.
  • Type: select modem type. Depending on your choice, adjust additional properties dedicated for the selected type (see instructions below): GSM modem, Simulator, Network modem, SMPP gateway.
  • Enable public mode. The modem in public mode is available to all objects regardless the list of supported devices. If such modems are several and they have the same link priority, the modem that is free at the moment will work. In case modems have different priorities, the modem with a greater priority will work.
  • Units. If public mode is disabled, you have to form the list of devices which will be assigned to this modem to execute any operations. Units become available after creating the modem. To complete creating the modem, press OK button. If the modem is created successfully, units become available to assign.

Notifications

  • Use for notifications. Indicate if this modem will be used for sending notifications.

SMS Replies

  • Use to deliver SMS replies. Indicate if this modem will be used to send replies to drivers.

Billing Plans

  • Limit modem activity by selected billing plans. Tick this checkbox to make this modem available only for selected billing plans. Move necessary billing plans from the left to the right. If the flag is not set, the modem will be available to all billing plans without exceptions. Access to modems can be also controlled through billing plan properties.

Modem Types

GSM modem

Indicate Serial port where the modem is located. Indicate Port speed. If any errors appear while operating, descend this value. Usually, SMS service center is strictly indicated on the SIM card, and you do not have to enter it here.

Enter the name for log file (without extension), for example modemus. In the logs directory a file with the indicated name and the extension .log will be created (like modemus.log), and it will collect all information about modem work.

Indicate Additional initialization AT commands as needed (consult instructions manual for the modem). Check Use 8-bit encoding only if needed.

Simulator

In this case indicate the absolute path to the Source file from which the simulator will take data. You can use the variable ${ADF_ROOT_PATH} that means the path of Wialon installation.

Network modem

Indicate Server host (you can enter IP address or DNS name), Server port to connect through, and the Server password to connect to the server.

SMPP gateway

Enter the name for Log file (without extension), for example modemus. In the logs directory a file with the indicated name and the extension .log will be created (like modemus.log), and it will collect all information about modem work.

Indicate Server host (you can enter IP address or DNS name), Server port to connect through, the Server password to connect to the server. If needed, indicate Server type, for example, VMS (voice mail system), OTA (over-the-air activation system), etc.

Enter Account name (login) and the Source address to recognize the sender (like phone number, company name or both). SMPP synchro mode is needed to make hardware diagnostics (while there is no notification that the first SMS was delivered, the second one will not be sent).

By default, SMS messages are transmitted with UDH method (User Data Header) where system information is placed at the beginning. SAR method (segmentation and reassembly) allows to place this information at the end in TLV format which is essential for several languages that se characters which cannot be transmitted in 8-bit encoding. In these cases the option Split long SMS using SAR method can be used to solve the problem.

Check the option Remove '+' in destination number to eliminate the plus symbol from destination phone numbers.

Check Use 8-bit encoding only if needed.

Enter Ton/Npi in indicated format if necessary.

In addition, you can set the variable ADF_SERIAL_SMPP_SRC_ADDR_TON in the configuration file. This variable defines the type of source address number in SMS being sent. Default value is 0.

Actions

The following actions can be performed over a modem:

  • delete – delete a modem.
  • begin_comm – begin communication that is start getting data from the modem.
  • end_comm – end communication that is stop getting data from the modem.
  • accessors – manage the access of different users to this modem. Access to modems is assigned in the same way as for users - see Access Management for details.
