6. Security and memory

6.1. Principles

The modem contains three types of memory:

The FLASH-EPROM, where factory configuration is stored permanently,

The RAM, where the modem configurations are stored temporary,

The NVRAM where semi-permanent data is stored even when the modem is turned off.

The first time your modem is turned on, or after a complete reset, these three memories are

identical and set to the default factory configuration.

The AT&Wn command saves the current configuration in the non-volatile memory, (n = 0 to 4)

or activates a factory configuration for the next reset (n=5 to 9).

For example :

AT &W0 save and activate the current user’s parameters in bank 0

AT &W5 activates factory configuration bank 0 for next reset, with no change on the

other user’s configuration banks.

The last stored user configuration will be loaded automatically on next power-up.

These memory operations are shown on the following diagram:

6.2. The phone directory

Up to 100 phone numbers can be stored in the modem's non-volatile memory, to be used by the

automatic dialler.

Save a number

AT&Z0:Directory::11:::A

This command saves automatically the directory in non-volatile memory

Dial a number

Display the directory
