Item Description
Filter Width Filter Width for calculating the moving average from loaded values of
signal strength. The first value indicates the lowest number of
loaded samples for which the value of calculated average is valid
and can be used to evaluate the relevant condition. The second
value is a filter buffer width in the steady state when the moving
average algorithm is applied (ie. if another sample is loaded, re-
places the oldest one, which means that the filter width remains
constant).
Holdoff Time If the default cellular module is unselected because of fail signal,
the other cellular module is selected after this holdoff time in sec-
onds. It is protection against quick module switching. It applies
only when fail on default module. Switch on roaming, data limit,
BIN or signal level is performed immediately.

4.5.1 PPPoE Bridge Mode Configuration
If you mark the Enable PPPoE bridge mode check box, the router activates the PPPoE
bridge protocol. PPPoE (point-to-point over ethernet) is a network protocol for encapsulating
Point-to-Point Protocol (PPP) frames inside Ethernet frames. The bridge mode allows you to
create a PPPoE connection from a device behind the router. For example, a PC connected to
the ETH port of the router. You assign the IP address of the SIM card to the PC.
For SmartMotion ST355 routers only: If you enable PPPoE bridge mode , it is not pos-
sible to use SMS Configuration features – the router will not send SMS and you can
not control the router via SMS! Send SMS feature in Administartion section will not work.
Also in Mobile WAN Status there will be no signal strength data displayed. This is caused
by using the same channel for sending AT commands in the cellular module in this ver-
sion of the router. If the channel is occupied by AT commands for PPPoE bridge, there is
no place for SMS AT commands.
The changes in settings will apply after clicking the
Apply
button.
