4. CONFIGURATION
4.3.4 Data Limit Configuration
Item Description
Data limit Specifies the maximum expected amount of data transmitted (sent
and received) over GPRS in one billing period (month).
Warning Threshold Specifies the percentage of the "Data Limit" in the range of 50 % to
99 %. If the data limit is exceeded, the router sends an SMS in the
following form
Router has exceeded (value of Warning Threshold)
of data limit.
Accounting Start Specifies the day of the month in which the billing cycle starts for
the SIM card used. When the service provider that issued the SIM
card specifies the start billing period, the router begins to count
the amount of transferred data starting on this day.
Table 22: Data Limit Configuration
If the parameters Switch to backup SIM card when data limit is exceeded and switch to default
SIM card when data limit isn’t exceeded (see next subsection) or Send SMS when data limit
is exceeded (see SMS configuration) are not selected, the data limit will be ignored.
4.3.5 Switch between SIM Cards Configuration
At the bottom of this configuration form you can specify the rules for toggling between the
two APNs, a single SIM card, or between the two SIM cards if you have inserted two SIM
cards. The router can automatically toggle between the network setups in the following cases:
•
the active connection to mobile network is lost,
•
the data limit is exceeded,
• the binary input on the front panel is activated.
Item Description
Default SIM card Specifies the default APN or SIM card. The router attempts to es-
tablish a connection to mobile network using the default. If you
specify this parameter as none, then the router boots up in the
off line mode and it is necessary to establish a connection to the
mobile network using an SMS message.
Backup SIM card Specifies the backup APN or SIM card.
