LABEL DESCRIPTION
Band Selection This field appears if you selected a mobile broadband device that allows you to select
the type of network to use. Select the type of mobile broadband service for your
mobile broadband connection. If you are unsure what to select, check with your mobile
broadband service provider to find the mobile broadband service available to you in
your region.
Select auto to have the card connect to an available network. Choose this option if you
do not know what networks are available.
You may want to manually specify the type of network to use if you are charged
differently for different types of network or you only have one type of network
available to you.
Select GPRS / EDGE (GSM) only to have this interface only use a 2.5G or 2.75G
network (respectively). If you only have a GSM network available to you, you may
want to select this so the ZyWALL/USG does not spend time looking for a WCDMA
network.
Select UMTS / HSDPA (WCDMA) only to have this interface only use a 3G or 3.5G
network (respectively). You may want to do this if you want to make sure the interface
does not use the GSM network.
Select LTE only to have this interface only use a 4G LTE network. This option only
appears when a USG dongle for 4G technology is inserted
Network Home network is the network to which you are originally subscribed.
Selection
Select Home to have the mobile broadband device connect only to the home network.
If the home network is down, the ZyWALL/USG's mobile broadband Internet
connection is also unavailable.
Select Auto (Default) to allow the mobile broadband device to connect to a network to
which you are not subscribed when necessary, for example when the home network is
down or another mobile broadband base station's signal is stronger. This is
recommended if you need continuous Internet connectivity. If you select this, you may
be charged using the rate of a different network.
Budget Setup
Enable Budget Select this to set a monthly limit for the user account of the installed mobile broadband
Control
card. You can set a limit on the total traffic and/or call time. The ZyWALL/USG takes
the actions you specified when a limit is exceeded during the month.
Time Budget Select this and specify the amount of time (in hours) that the mobile broadband
connection can be used within one month. If you change the value after you configure
and enable budget control, the ZyWALL/USG resets the statistics.
Data Budget Select this and specify how much downstream and/or upstream data (in Mega bytes)
can be transmitted via the mobile broadband connection within one month.
Select Download to set a limit on the downstream traffic (from the ISP to the
ZyWALL/USG).
Select Upload to set a limit on the upstream traffic (from the ZyWALL/USG to the
ISP).
Select Download/Upload to set a limit on the total traffic in both directions.
If you change the value after you configure and enable budget control, the ZyWALL/
USG resets the statistics.
Reset time and Select the date on which the ZyWALL/USG resets the budget every month. If the date
data budget
you selected is not available in a month, such as 30th or 31st, the ZyWALL/USG resets
counters on
the budget on the last day of the month.
