The SRM-100 Secure Rack Modem provides password-protected, dial-in
access to rack mounted serial communications equipment. The SRM's non-volatile
memory can store up to 100 menu-defined passwords, each with an optional
dial back or call back number. The unit can also track access activity
for each password and create a log record of successful and unsuccessful
connection attempts.
The SRM is ideal for remote installations. The unit always resets
itself to a fixed baud rate, and no external "AT" commands are required
to configure the modem upon power-up. This provides the perfect solution
for communicating with equipment that cannot send an "AT" setup string.
Password
Protected Access
Each menu-defined password can be assigned an individual 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
Connection Log and the Password Directory. The Connection Log lists
the 100 most recent connection attempts, along with the password entered,
port used, time, date, call duration, and status at disconnect. The
Password Directory displays all user names, passwords, and dial back
numbers, and also lists the number of times that each password has been
used. The Connection 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.
Local or
Remote Configuration
All configuration tasks are performed via the SRM's command
mode. The command mode features a series of command-driven configuration
menus, which are used to select port parameters, define passwords and
dialback numbers, and review connection activity. The command mode can
be accessed locally via a serial DB9 Console Port, or remotely via dial-up
connection. This makes remote installation a breeze. Simply plug in
the power and phone line, and the system administrator can call the
SRM and download all parameters, either by keystroke or ASCII file.
In addition to allowing command mode access by a local system administrator,
the SRM's Console Port can also be connected to a secondary serial device,
such as a reboot switch. Although most dial-in users are only allowed
to access the primary device connected to the SRM modem port, a remote
administrator can also access a secondary device connected to the console
port in order to initiate reboot operations or take equipment off-line.
Three Different
Operating Modes
The SRM-100 provides three distinct operating modes:
- 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. When accessed via modem, the command mode
also allows access to an optional secondary device installed at the
SRM console port.
- Unsecured Mode: If necessary, the SRM's security features
can also be disabled. When security is disabled, the SRM will function
like a normal, unsecured, rack modem; callers are allowed to access
the secure device without entering a password.
