Remote Device Access and Control
Asentria products are placed at remote sites to help you manage and monitor your remote equipment. Typically, you connect to a remote Asentria product via modem or Ethernet TCP/IP. This gives you the capability to communicate through the Asentria product to other remote devices located at that site, typically serial devices connected to the Asentria product. Asentria products offer many valuable features for remote access and control applications, including:
|
Several Asentria products support serial alarm monitoring. The right product for
you will depend on your application and the other features you want to use in addition
to serial alarms. In order to determine which of our products best suits your needs,
please read the following brief discussion regarding important aspects of serial
alarm detection, and then use the Product Selection Wizard
to select the product that best fits your needs.

Pass-Through Access
Several Asentria products
which offer dialup or network connectivity also provide a pass-through feature for
communicating directly to any devices connected to the Asentria product serial ports. Several
Asentria products offer a single serial port, whereas others offer up to six serial
ports. You can use a TCP/IP port number to connect directly to a specific
serial port, or you can connect to a specific serial port based on the username/password
that is entered upon login. You can also select which serial port to communicate via a
text menu presented after a general login to the Asentria product. (back

Customized User Profiles
For applications
which involve multiple users with different login rights and restrictions, we offer
a product which has 12 customizable user profiles that can be used to exactly define
the behavior and limitations of each user's access to the Asentria product. (back

Menu Access to Allowed Ports
When a user logs in,
some Asentria products can then display a text menu of the serial devices for which a user
has access rights. This can also include a selection for command and configuration
access to the Asentria product itself. Ports for which the user
does not have rights to simply don't show up on the menu. Each serial port on the
device can be 'named' e.g. 'Nortel Alarm Port' or 'Router Admin Port', so the user
can identify which port they want to select. (back

CHAP One-Time Passwords
Sometimes you want to make
sure that a password can only be used once. Using a challenge/response protocol
based on a shared-secret. Asentria products will calculate and issue a challenge
code during the login process which, when entered into our Response Generator program,
generates a response code that is only good once, and gives you the access appropriate
to the user who is logging in. (back

Caller ID Restrictions
For extra security in
modem dial-in applications, Asentria products offer the ability to restrict
incoming modem access to only specified phone numbers. If a given number
is not on the list then the modem will not answer the phone. (back

Secure Modem Callbacks
For applications where
Caller ID Restriction is not possible or desirable, an alternative is to use Secure
Modem Callbacks. In this case, the User's profile includes up to three callback
phone numbers. When that User logs in they are prompted to enter a number.
The Asentria product then hangs up and calls back the selected callback number for that user.

Password Sent to Email/Pager
For further security
options, a one-time password can be sent to a user via email or pager. The
User connects to the Asentria box and enters their normal password. The box hangs up
and then sends a one-time password to the email address or pager indicated in that
User's profile. The user then connects back to the box and enters the one-time
password (not the User's normal password). This gives the user
the normal access as defined in their User profile. (back

IP Routing to Remote Network Devices
In addition
to remote access to connected serial devices, several Asentria products can also
be used as a gateway to communicate to other TCP/IP devices on the same remote network,
such as a web interface or telnet interface of routers, switches, etc.
When properly set up, you can dial into the unit using dial-up networking and establish
a PPP connection with the Asentria product which then allows you to route to other devices
on the remote network. For security reasons this feature requires very specific
settings plus DIP switch enabling. This feature can be used as an out-of-band
backup to access the remote network if normal paths to the remote site are down.

Control Remote Devices via Output Relays
In
addition to accessing remote devices, Asentria products allow you to control
on-board and remote relays for controlling other devices. Output relays can be controlled
via SNMP or can be triggered automatically as an alarm action. Output relays allow
you to activate sirens, cameras, lights or other electronic devices in remote locations,
which often saves the time and expense of sending personnelto a remote site. (back
