Security Functions
This appendix describes the security functions of the Model XM128 ISDN Digital Modem. The
modem provides two types of security functions that may be enabled to prevent unauthorized
connections.
Security Types and Levels
The Model XM128 modem provides the following types of security:
•
Type 1 security is used when the remote modem is a NETGEAR modem.
•
Type 2 security is used when the remote modem is a non-NETGEAR device.
With a Type 1 connection, the dial-in (remote) modem sends in its supervisor password for
matching with the prestored password list of the local modem. With a Type 2 connection, the
remote terminal is prompted to enter the password at the initial connection. The local
Model XM128 modem matches the entered password with the prestored password list.
