6.3 The Cellular Backup Screen
The USB port of the Zyxel Device allows you to attach a cellular dongle to wirelessly connect to a cellular
network for Internet access. You can have the Zyxel Device use the cellular WAN connection as a
backup to keep you online if the primary WAN connection fails for Consecutive Fail times. Consult your
cellular service provider to configure the settings in this screen. Disconnect the DSL and Ethernet WAN
ports to use the cellular dongle as your primary WAN connection, as the Zyxel Device automatically uses
a wired WAN connection when available.
Figure 79 Internet Access Application: Cellular WAN
Use this screen to configure your cellular settings. Click Network Setting > Broadband > Cellular Backup.
The actual data rate you obtain varies depending on the cellular card you use, the signal strength to
the service provider's base station, and so on.

DESCRIPTION
Divide the DSL line rate (bps) by 424 (the size of an ATM cell) to find the Peak Cell Rate (PCR). This
is the maximum rate at which the sender can send cells. Type the PCR here.
The Sustain Cell Rate (SCR) sets the average cell rate (long-term) that can be transmitted. Type
the SCR, which must be less than the PCR. Note that system default is 0 cells/sec.
Maximum Burst Size (MBS) refers to the maximum number of cells that can be sent at the peak
rate. Type the MBS, which is less than 65535.
This section is available only when you select ADSL over ATM in the Type field.
Click this switch to enable or disable VLAN on this WAN interface. When the switch goes to the
right
, the function is enabled. Otherwise, it's not.
IEEE 802.1p defines up to 8 separate traffic types by inserting a tag into a MAC-layer frame that
contains bits to define class of service.
Select the IEEE 802.1p priority level (from 0 to 7) to add to traffic through this connection. The
greater the number, the higher the priority level.
Type the VLAN ID number (from 0 to 4094) for traffic through this connection.
