outgoing calls. Options are:

None: No authentication for outgoing calls.

CHAP - Your ZyWALL accepts CHAP requests only. 

PAP - Your ZyWALL accepts PAP requests only.

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.
