1.10.4. DNS address configuration
If
Get DNS address from operator
option is selected, the router will automatically
attempt to get the IP addresses for the primary and secondary DNS servers from the cellular
network operator.
1.10.5. 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.
1.10.6. 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.
