CONFIGURATION
42
Attention! If one SIM card is inserted into the router, which has two different APN’s,
the router cannot have the second SIM socket mounted. Otherwise it will switch to
secondary APN false. Also, correct PIN must be filled. For SIM cards with two APN’s
there will be the same PIN for both APN`s. Otherwise the SIM card can be blocked by
false SIM PIN.
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 modem will automatically send the ping question to the selected domain
name or IP address (Ping IP Address) in periodic time intervals (Ping Interval). If the PING
failed, new ping be sent immediately. 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 data sending via GPRS. Parameter Warning
Threshold determine per cent of Data Limit in the range of 50% to 99%, which if is exceeded,
then the router sends an SMS in the form Router has exceeded (value of Warning
Threshold) of data limit. By the parameter Accounting Start it is possible to specify day
in month when it 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.
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 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.
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. Failure of the
PPP connection can occur in two ways. When I start the router, when three fails to establish
a PPP connection. Or if it is checked Check the PPP connection, and is indicated by the loss
of a PPP connection.
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.
