Setting and Modifying Passwords 
Up to 40 user passwords can be defined using the [AT*Hn] command, where 'n' represents the 
index to the entry (n=0-39). 
The corresponding 40 callback numbers are defined by [AT&Zn=xxx] command, where 'n' 
represents the index to the entry, and 'xxx' represents the assigned callback phone number. Any 
character (ASCII 0-127) can be used in the password table. The maximum password length is 8 
characters for each entry. 
Security functions are only accessible through AT commands in terminal mode. 
A supervisory password is required for adding or modifying entries. The default supervisor 
password is 'ZyXEL' when the omni.net is shipped from the factory. The supervisory password is 
sent to the remote device if Type 1 security is set at the remote end. 
Modifying the Supervisory Password 
To modify the supervisor password, use [AT*HS]. 
The system will prompt for the original password and a new password. Then re-enter the new 
password for verification. For example: 
Password:
********
 
(Enter current supervisory password) 
Password:
********
 
(Enter new supervisory password) 
Verify:
********
 
(Enter the new supervisory password again) 
OK
