Western Telematic SRM-100 - Manual (Page 5)

1. Introduction
The SRM-100 Secure Rack Modem is designed for applications that require secure, dial-up
access to console ports on rack mounted equipment. WTI's Secure Rack Modem can recognize
up to 100 passwords, and track activity for each password and create a log record of successful
and/or unsuccessful access attempts.
Password Protected Access
Up to 100 passwords can be stored in the SRM's non-volatile memory. Each password can be
assigned a user name for easy reference, and an optional Dial Back number which instructs the
unit to call the user at a predefined number before allowing access to the secure device. A
separate System Password restricts access to the SRM command mode, this allows the system
administrator to contact the unit via modem in order to change parameters or check access
activity.
Access Activity Logs
The SRM-100 provides two convenient ways to track access activity; the Audit Log and the
Password Directory. The Audit Log lists the 100 most recent connection attempts, including
the time, date, password entered, port used, call duration, and reason for disconnect. The
Password Directory displays user names, passwords and dial back numbers, and counts use of
each individual password. The Audit Log and Password Directory can only be viewed by the
System Administrator; callers who log on with a User Password are not allowed to view these
screens.
Three Different Operating Modes
The SRM-100 provides three distinct operating modes; the User Mode, the Command Mode,
and the Unsecured Mode.
· User Mode: Provides password protected access to the secure device connected to the
SRM's serial modem port.
· Command Mode: Provides password protected access to the SRM Command Menus,
which are used to define passwords and select configuration parameters.
· Unsecured Mode: When this mode is activated, the SRM will function like a normal,
unsecured modem; callers are allowed to access the secure device without entering a
password.
