ZyXEL Communications omni series user manual Security Functions, Security Types and Levels

13 Security Functions

The omni provides security functions that may be enabled to prevent unauthorized connections. Two types of security functions are provided.

Security Types and Levels

Type 1 security is to be used when the remote TA is a ZyXEL ISDN TA.

Type 2 security is to be used with non-ZyXEL remote TA’s.

With a Type 1 connection, the dial-in (remote) TA will send in its supervisor password for matching with the local omni’s pre-stored password list. With a Type 2 connection, the remote terminal will be prompted to enter the password at the initial connection and the local omni will match the entered password with the pre-stored password list.

The two types of security are summarized in the table below:
