Table 27 Cellular Interface Commands
COMMAND DESCRIPTION
[no] interface interface_name Creates the specified interface if necessary and enters sub-
command mode. The
no command deletes the specified
interface.
[no] account profile_name Specifies the ISP account for the specified cellular interface.
The no command clears the ISP account field.
[no] band {auto|wcdma|gsm} Sets (or clears) the cellular band that the cellular interface
uses.
auto has the ZyWALL always use the fastest network that is
in range.
gsm has 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 use this so the ZyWALL does not spend
time looking for a WCDMA network.
wcdma has this interface only use a 3G or 3.5G network
(respectively). You may want to use this if you want to make
sure the interface does not use the GSM network.
[no] network-selection {auto|home} Home network is the network to which you are originally
subscribed.
Home has the 3G device connect only to the home network. If
the home network is down, the ZyWALL's 3G Internet
connection is also unavailable.
Auto is the default setting and allows the 3G device to
connect to a network to which you are not subscribed when
necessary, for example when the home network is down or
another 3G 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.
[no] budget active Sets a monthly limit for the user account of the installed 3G
card. You can set a limit on the total traffic and/or call time.
The ZyWALL takes the actions you specified when a limit is
exceeded during the month. Use the no command to disable
budget control.
[no] budget time active <1..672> Sets the amount of time (in hours) that the 3G connection can
be used within one month. If you change the value, the
ZyWALL resets the statistics. Use the no command to disable
time budget control.
