1.10.3. DNS address configuration
If Get DNS address from operator option is selected, the router will automatically
attempt to get an IP address for the primary and secondary DNS servers from the network
operator.
1.10.4. Check PPP connection configuration
You may set the Check PPP connection flag to enable automatic test messages for
the cellular network. In some cases, the PPP connection may still be active but the router will
not be able to send data over the cellular network. The router will send a Ping command to
the Ping IP Address at periodic time intervals (Ping Interval) If the router does not receive a
response to the Ping command, it will retry up to the number of times specified by the Ping
Probes parameter. After that time, it will switch itself to a backup router until the PPP
connection is restored.
Item Description
Ping IP Address Destination IP address or domain name for the ping queries.
Ping Interval Time intervals between the outgoing pings.
Table 15: Check PPP connection configuration
If the Enable Traffic Monitoring option is selected, the router stops sending ping
questions to the Ping IP Address and it will watch traffic in PPP connection. If PPP
connection is without traffic longer than the Ping Interval, then the router sends ping
questions to the Ping IP Address.
Note: It is recommended that you enable Check PPP Connection to ensure reliable data
communication.
1.10.5. Data limit configuration
The router can be configured to automatically send an SMS message or switch to a
backup SIM card if the amount of data sent or received exceeds a given threshold for the
monthly billing period.
Item Description
Data limit With this parameter, you can set the maximum expected amount of data
transmitted (sent and received) over the cellular network in one billing
period (month).
Warning
Threshold Percentage of Data Limit (50% to 99%). The router will send an SMS
message with Router has exceeded (value of Warning Threshold)
of data limit in the message text when this threshold is exceeded.
Accounting Start Sets the day of the month in which the billing cycle starts for the SIM
card being used. The start of the billing period is determined by the
network operator.
Table 16: Data limit configuration
If neither one of the options Switch to backup SIM card when data limit is
exceeded (see next) or Send SMS when data limit is exceeded (see SMS configuration) is
selected, the data limit will be ignored.
