CONFIGURATION
46
6.9. UMTS/GPRS Configuration
To enter the GPRS connection configuration select the GPRS menu item.
If the Create GPRS connection option is selected, the modem automatically tries to establish
GPRS connection after switching-on. In this window it is possible to define Username,
Password, authentificate protocol in the GSM network (Authentication), IP address
(IP Address) and phone number (Phone Number) for two different APN. If the IP address field
is not filled in, the operator automatically assigns the IP address when it is establishing
the connection. The router uses phone number *99***1# as default number. When it is set
other phone number, it will be use for establish GPRS or CSD connection.
If the APN field is not filled in, then the router automatically selects the APN
by the IMSI code of the SIM card. If the PLMN (operator number format) is not in the list of
APN, then default APN is “internet“. The mobile operator defines APN. The PLMN parameter
is possible to define in Operator item. Network Type item defines the way of data transmition,
respectively Automatic selection according to network availability or UMTS/HSDPA
or GPRS/EDGE technology. By parameter PIN it is possible to put PIN to the SIM card always
during the starting of the router.
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.
