PIN Code This field displays with a GSM or HSDPA 3G card. A PIN (Personal Identification
Number) code is a key to a 3G card. Without the PIN code, you cannot use the 3G
card.
Enter the 4-digit PIN code (0000 for example) provided by your ISP. If you enter
the PIN code incorrectly, the 3G card may be blocked by your ISP and you cannot
use the account to access the Internet.
If your ISP disabled PIN code authentication, enter an arbitrary number.

Connectivity
Check
The interface can regularly check the connection to the gateway you specified to
make sure it is still available. You specify how often the interface checks the
connection, how long to wait for a response before the attempt is a failure, and
how many consecutive failures are required before the ZyWALL stops routing to
the gateway. The ZyWALL resumes routing to the gateway the first time the
gateway passes the connectivity check.
