PPP WAN modes
PPP WAN Auto
In this mode, the WAN IP connection is always connected.
PPP WAN Conditional
In this mode, the WAN IP connection is based on the LAN PPP connection, once
the LAN PPP connection is up, the WAN IP connection will be established and
vice versa. This is to save data usage and device power consumption.
PPP WAN Manual
In this mode, the device needs to send AT commands to bring up/bring down the
WAN IP connection. The commands are sent over the LAN PPP connection using
AT over IP to the modem (not module AT over IP).
AT$$IPCTOP to open WAN PPP connection.
AT$$IPCTCP to close WAN PPP connection.
There are several commands that are not needed when the Intelimax+ is in PPP server
mode such as:
AT$$IPCTOS
AT$$IPCTCS
AT$$TCPDEL
All socket related commands are not supported because when the Intelimax+ works in
PPP server mode, the TCP/UDP socket on the WAN side is no longer needed, the modem
now is a gateway.
PPP Dialling Modes
Three Dial modes are supported:
•
MS Chat
•
No Dial
•
Modem Emulation
Modem Emulation is the most commonly used option. In this mode, the PPP client will
send dialling strings such as ATV1; AT+CGATT=0; ATDT*99***1#, etc., and user can define
dialling strings to be sent to the PPP server. The user can define what string it will expect
to hear back from PPP server before the PPP connection is initiated such as “cr1000dial”.
In this mode, either both of these response fields can be configured or just the answer
