■AT command mode

In AT command mode the Nokia 30 operates as a wireless modem. The wireless connection is established and data is sent using AT commands integrated in the application module.

The AT command mode is available either on the D9 connector of the RS-232 adapter or on the 50-pin M2M System Connector located on the bottom of the Nokia 30 GSM Connectivity Terminal.

The AT commands, which are used to control the terminal, can be found in the AT Command Guide for Nokia 30 GSM Connectivity Terminal on the Nokia 30 CD-ROM and on the Nokia website at http:// www.forum.nokia.com. The Nokia 30 GSM Connectivity Terminal supports most ITU-T V.25ter, ETS GSM 07.05 and ETS GSM 07.07 commands.

■M2M System mode

In M2M system mode the Nokia 30 GSM Connectivity Terminal operates as a part of the Nokia M2M Platform, which is a complete, wireless end-to-end solution for machine communication. Together with the Nokia M2M Gateway the Nokia 30 forms an application platform.

The Nokia 30 incorporates a host of features that can be used in M2M System mode. For example, enhanced reliability and security is available in M2M System mode. The connection between the Nokia 30 and the application module is checked periodically by live checks and if the connection is broken, it can be reset automatically. Mutual authentication can also be ensured between the Nokia 30 and the Nokia M2M Gateway. In M2M System mode the wireless connection is established and data is sent using the CORBA method calls integrated in the application module.
