CONFIGURATION

Example of the VRRP protocol:

5.9. UMTS/GPRS Configuration

To enter the GPRS connection configuration select the GPRS menu item.

If the Create GPRS connection option is selected, the router automatically tries to establish

GPRS connection after switching-on. In this window it is possible to define Username,

Password and IP address 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.

If the APN field is not filled in, then 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 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.
