CONFIGURATION
45
The choice Get DNS address from operator is given for easier configuration on client
side. If this field is filled in, then the router tries to get an IP address of primary and
secondary DNS server from the operator automatically.
If the Check PPP connection option is selected, it has active control of connection
over PPP. The router will automatically send the ping question to the selected IP address
(Ping IP Address) in periodic time intervals (Ping Interval). After three unsuccessfully pings
on appropriate IP address the router terminates connection and tries to establish a new
connection. It is possible to use, for example, the DNS server of a mobile operator as the
ping IP address.
If the Enable Traffic Monitoring option is selected, then 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.
Parameter Data limit set limit for sending via GPRS. By the parameter Accounting
Start it is possible to specify after which amount of data will start accounting defined in Data
limit. If the parameter Switch to backup SIM card when data limit is exceeded (see next) or
Send SMS when datalimit is exceeded (see SMS configuration) are not selected the data
limit will not count.
Parameter Warning Threshold determine per cent of Data Limit, which if is exceeded,
then the router sends an SMS in the form router has exceeded (value of Warning Threshold)
of data limit.
At the bottom of configuration it is possible to set rules for switching between two
APN’s on the SIM card, in the event that one SIM card is inserted or between two SIM cards,
in the event that two SIM cards are inserted. Parameter Default SIM card sets default APN or
SIM card, from which it will try to establish the PPP connection. If this parameter is set to
none, the router launches in off-line mode and it is necessary to establish PPP connection
via SMS message. If PPP connection fails, then the parameter Switch to other SIM card
when connection fails ensures switch to secondary SIM card or secondary APN of the SIM
card. In case that the roaming is detected the parameter Switch to backup SIM card when
roaming is detected enables switching to secondary SIM card or secondary APN of the SIM
card. Parameter Switch to backup SIM card when data limit is exceeded enables switching to
secondary SIM card or secondary APN of the SIM card, when the data limit of default APN is
exceeded. Parameter Switch to primary SIM card after timeout defines conditions, how to
switch back to the default SIM card or default APN. Parameter Switch to primary SIM card
after timeout enable defines the method, how the router will try to switch back to default SIM
card or default APN.
If parameter Backup SIM card is set to none, then parameters Switch to other SIM
card when connection fails, Switch to backup SIM card when roaming is detected and Switch
to backup SIM card when data limit is exceeded switch the router to off-line mode.
Parameter Initial Timeout sets the time after which the Router tries to make connection
with default APN, range of this parameter is from 1 to 10000 minutes. Parameter Subsequent
Timeout sets the time period for every other next attempt to make connection with default
APN, range is from 1 to 10000 minutes. Parameter Additive Constant sets the amount of time
which is added to every attempt at main connection establishment after unsuccessful defined
attempt (for example: after a second unsuccessful attempt at main connection establishment
time of next attempt is extended by about 30 minutes etc.). Range is from 1 to 1000 minutes.
