(in Mega bytes) can be transmitted via the 3G connection within one
month.

ISP to the ZyWALL).
Select Upload to set a limit on the upstream traffic (from the ZyWALL

Reset time and
data budget
counters on Select the date on which the ZyWALL resets the budget every month.
If the date you selected is not available in a month, such as 30th or

Reset time and
data budget
counters This button is available only when the 3G card is connected.
Click this button to reset the time and data budgets immediately. The
count starts over with the 3G connection’s full configured monthly
time and data budgets. This does not affect the normal monthly
budget restart; so if you configured the time and data budget
counters to reset on the second day of the month and you use this
button on the first, the time and data budget counters will still reset
on the second.

the current connection, but you cannot build a new connection if the
existing connection is disconnected.
