2.3.2 Connection Using CDMA

1 When the ICX35-HWC is powered on, it automatically searches for cellular
service using CDMA-based cellular technology.
2 The ICX35-HWC establishes a PPP (Point-to-Point Protocol or "dial" up
connection) link to the cellular network, also called registering on the network,
and receives an IP address.
3 When the ICX35-HWC has received its IP address from the cellular provider,
a connection to the Internet or the cellular network is also available for
computers or other devices to connect directly to the ICX35-HWC.
4 The CDMA network information is now displayed on the Status web page.

2.3.3 SIM Card Security

To protect a SIM card from others using it for phone calls or cellular data, a SIM
PIN can be used. When a SIM PIN is used, the SIM card will automatically lock
upon an ICX35-HWC reboot. The PIN protection enablement, PIN (Personal
identification number), and PUK (PIN unlock key) codes are saved on the SIM
card. Replacing the SIM card will require a reconfiguration of the SIM settings.
Most mobile devices offer SIM PIN protection. At startup, if the PIN security
function is active, the user must enter a 4 to 8 digit PIN to enable the ICX35-
HWC's non-emergency functions. The user can save the PIN code in the
configuration in an encrypted format.
