Mobile PPP parameters
Mobile telephone modules fitted into the router use PPP to connect to the network and send and
receive traffic. This section describes parameters relevant to setting up a mobile telephone
module.
Use SIM Any, SIM1, SIM2
These radio buttons are used to select which of the SIM cards fitted should be used by the
module.
Detach W-WAN if the link fails
When enabled, causes the router to issue the command to detach the mobile telephone
module from the wireless network if it detects that the link has failed. Link failure is detected
by a PPP ping response timer or by a firewall request.
Detach W-WAN between connection attempts
Controls whether the module stays attached to the network if multiple connection attempts
are required to establish a connection. This functionality may be useful if the connection to
the mobile telephone network is not very reliable. Connecting to the mobile telephone
network to send and receive data is a two-stage process. The first stage is where the module
signals its wish to join the network and is accepted by the local cell. The second stage involves
negotiating the link parameters and transferring data. Sometimes it may be necessary to
cleanly detach from the network in order to start the process from the ground up.
