PollCat NetLink II - User’s Guide
5.4.4.1. Dialback Security
This feature provides an extra measure of security for modem access to
command mode. When this option is properly configured and enabled,
callers will not be granted immediate access to command mode upon
entering a valid password; instead, the unit will disconnect, and then dial
a user-defined number before allowing access via that number. If desired,
users may also be required to re-enter the password after the NetLink II
dials back.
In order for Dialback Security to function, you must first select a Dial
Back option via the Modem Port menu (Section 5.4.4,) and then define a
Dialback Number for each desired user account (Section 5.3.1.) Note that
Dialback Numbers are defined via the User Directory menu, and if desired,
each user can have a different Dialback number.
To access the Dialback Security menu from the Modem Port Configuration
menu, type 36 and press [Enter]. The Dialback Security menu offers the
following options:
1. Dial Back with Password: Dialbacks will be performed for user
accounts that include a Dialback Number, and the login prompt will
be displayed when the user’s modem answers (accounts that include
a Dialback Number will be required to re-enter their login name/
password when their modem answers.) If the account does not include
a Dialback Number, then that user will be granted immediate access
and a Dialback will not be performed.
2. Dial Back without Password: Dialbacks will be performed for user
accounts that include a Dialback Number, and the login prompt will
not be displayed when the user’s modem answers. If the account
does not include a Dialback Number, then that user will be granted
immediate access to command mode, and a Dialback will not be
performed.
