4.4.3.2 Activating Multiple Network Connections
To activate multiple Network Connections for additional computers, repeat the instructions for a single Network
Connection. Each time a context is activated for a particular local IP address, it will show up in the table.
Multiple network connections are only possible in NAT mode.
Up to 11 computers can be connected to the BGAN terminal. More than one computer can be connected to the
Ethernet interface by using either a hub, router or a switch. When a hub is used, the BGAN terminal operating in
NAT Mode can allocate private IP addresses to each computer connected to the hub, allowing each computer to have
a dedicated primary Network Connection. In this case, each computer has the ability to individually attain up to a
492 kbps connection to the BGAN network. If a router is used, the BGAN terminal operating in Relay Mode allows
a simplified connection to the router. However, this would limit the throughput to all those computers behind the
router to a single 492 kbps connection, using a single Network Connection.
4.4.4 Automatic Network Connections
See Figure 4-8. The automatic network connection feature provides the ability to create a Network Connection
automatically using a specified IP address of the Terminal Equipment (TE). The TE is an IP device (e.g., IP camera),
which can transfer IP data. The IP Automatic Network Connections page allows automatic context activation with
two different methods:
• Terminal Equipment using Static IP addressing, to create automatic Network Connections when a specified
IP Address is detected on the local network
• Terminal Equipment using the BGAN Terminal DHCP Server's assigned IP addresses, to create automatic
Network Connections when a specified IP Address is detected on the local network
Selecting "ON": A one-time automatic connection is established when a specified IP Address is detected on a local
network.
Selecting "DA": An automatic connection is established when data traffic sourced by the specified IP Address is
detected on a local network. If previously established data connection went inactive, it will be reactivated each time
data is sent.
The BGAN Terminal does not save and restore these defined
contexts across power cycles, and requires the reception of a
subsequent ARP packet following a power cycle to initiate the
definition of the context. Decreasing ARP refresh times from
the connected router or device to reinitiate a context definition
may be required to ensure timely network connectivity.
The 24/7 Network Connection Keep Alive property will allow the data connection to remain active in the event of
a network timeout due to a long period of inactivity.
