DESCRIPTION
A PIN (Personal Identification Number) code is a key to a 3G card. Without the PIN
code, you cannot use the 3G card.
Enter the PIN code (four to eight digits, 0000 for example) provided by your ISP. If
you enter the PIN code incorrectly, the 3G card may be blocked by your ISP and
you cannot use the account to access the Internet.
If your ISP disabled PIN code authentication, enter an arbitrary number.
This field is available only when you insert a GSM 3G card.
Enter the phone number (dial string) used to dial up a connection to your service
provider's base station. Your ISP should provide the dial string.
By default, *99# is the dial string for GSM-based networks and #777 is the dial
string for CDMA-based networks.
Select Nailed-Up if you do not want the connection to time out.
This specifies the time (from 0 to 9999) in seconds that elapses before the selected
device automatically disconnects from the ISP.
Select this option if your ISP did not assign you a fixed IP address. This is the
default selection.
Select this option if the ISP assigned a fixed IP address.
Enter your WAN IP address in this field if you selected Use Fixed IP Address.
Network Address Translation (NAT) allows the translation of an Internet protocol
address used within one network (for example a private IP address used in a local
network) to a different IP address known within another network (for example a
public IP address used on the Internet).
Select this checkbox to enable NAT.
Select this check box to turn on IGMP (Internet Group Multicast Protocol). IGMP is
a network-layer protocol used to establish membership in a Multicast group - it is
not used to carry user data.
Choose None (default), IGMP-V1 or IGMP-V2. IGMP (Internet Group Multicast
Protocol) is a session-layer protocol used to establish membership in a Multicast
group – it is not used to carry user data. IGMP version 2 (RFC 2236) is an
improvement over version 1 (RFC 1112) but IGMP version 1 is still in wide use. If
you would like to read more detailed information about interoperability between
IGMP version 2 and version 1, please see sections 4 and 5 of RFC 2236.
Select this check box to set a monthly limit for the user account of the installed 3G
card. You must insert a 3G card before you enable budget control on the selected
device.
You can set a limit on the total traffic and/or call time. The selected device takes
the actions you specified when a limit is exceeded during the month.
Select this check box and specify the amount of time (in hours) that the 3G
connection can be used within one month.
If you change the value after you configure and enable budget control, the selected
device resets the statistics.
