Connecting to your cellular provider

The RLXIC-EH uses your cellular provider as an ISP (Internet Service Provider)
to connect you to the Internet.
1.3.1 Steps of a connection:
1 When your RLXIC-EH is powered on, it automatically searches for cellular
service using GSM/GPRS.
2 Your RLXIC-EH establishes a PPP (Point to Point Protocol or "dial" up
connection) link to the your cellular provider network, also called registering
on the network, and receives an IP address.
3 When your RLXIC-EH has received its IP address from your cellular provider,
a connection to the Internet or the cellular network is also available for a
computer or other device connected directly to the RLXIC-EH.
The RLXIC-EH will perform a one-to-one routing for all internet traffic to and
from the computer or other end device. One-to-one means that your RLXIC-EH
will provide a connection for one device to the Internet at a time. In Private Mode,
the RLXIC-EH will provide NAT (Network Address Translation) for the computer
or other end device.
Note: The RLXIC-EH does not provide advanced routing required by one-to-many (several devices
connected to one port). If you need to have more than one device connected to the Internet
through your RLXIC-EH, you will need to have a router connected to the modem. The modem
would provide the one-to-one connection to the router with the router configured to provide a
broader NAT service to the other devices connected to it.
1.3.2 Dynamic vs. Static IP Addresses
There are two types of addresses on networks: dynamic and static.
Dynamic addresses are assigned on a "need to have" basis. Your RLXIC-EH
might not always receive the same address each time it connects with your
cellular provider.
Static addresses are permanently assigned to a particular account, and will
always be used whenever your RLXIC-EH connects to the Internet. The IP
address will not be given to anyone else.
