Using the Web Page(s)
In circumstances where it is necessary to communicate with the router remotely via a normal ana-
logue modem (perhaps because no ISDN line is available), this page may be used to set up the vari-
ous parameters associated with controlling the modem.
ASY port:
This parameter is used to specify the ASY port to which the external modem is connected.
The default value is 255, which means that no external modem is available. The other available
options depend on the model and can be an ASY port number or a MUXn number.
The MUXn options are used to select those ports that are available for use in multiplexed
mode with the built-in GPRS module.
W-WAN mode:
This option allows you to configure a second W-WAN PPP connection. In this case, the ASY
port used would typically be a virtual port corresponding to a spare multiplex channel into the
internal W-WAN module.
When W-WAN mode is “ON”, additional W-WAN specific parameters such as the APN are
available. To view these parameters, first turn on W-WAN mode and click OK. Then reselect the
external modem configuration page using the left hand menu tree. For details on the W-WAN
options, refer to the Configure > W-WAN Module section.
Modem init string n:
Up to three initialisation strings may be defined which are issued in sequence to the modem
each time a dial-out call is made.
Hang-up string:
This parameter is used to define the hang-up string to be used when call is to be terminated
(usually ATH).
Post hang-up string:
This parameter is used to define a string which is sent to the modem immediately following a
successful hang-up if necessary.
Listening init string:
The listening init string is sent at intervals specified by a listening init interval parameter. The
command will be sent to the external modem so it can auto detect the baud rate of the unit.
This saves on modem configuration.
Listening init interval (secs):
Specifies how often the above init string is sent out of the serial port.
Maximum RING count before answering incoming call:
The maximum number of rings the unit will allow before answering the call.
