Maintain LAN Visibility Of Your Remote Sites Even When LAN Access Is Down

Maintain LAN Visibility of Your Remote Sites Even When LAN Access is Down
The NetGuardian 832A connects directly to your LAN and also has an internal dial-up modem. The NetGuardian's dial-up connection can be used as a primary or secondary data path.

Even if your network has moved to LAN-based monitoring, it's still a smart idea to also have a dial-up connection for your remotes. A primary or secondary dial-up path will give you visibility of your remote sites when LAN access is unavailable.

The NetGuardian 832A is principally a LAN-based remote, but it also has an internal 33.6K modem, which can be used as a primary or secondary connection path.

Dial-up as a primary path for sites without LAN access

You may have remote sites that are so distant that they don't have access to your LAN. But that doesn't mean that you can't integrate them into your network's LAN-based monitoring solution. The NetGuardian can report alarms through a dial-up connection to a PPP server linked to your LAN. As your network expands, these distant remote sites can be integrated into your LAN without disrupting your network monitoring.

Dial-up as a backup secondary path

With network monitoring, more security is always better. Even if your remote site has access to your LAN, you should plan for the contingency that your LAN may go down. And it is precisely when communication links are having problems that you most need access to your network monitoring. A NetGuardian with LAN connection and dial-up backup will ensure that you have constant visibility of your site.

Smoothly Migrate Dial-Up Sites to LAN-Based Monitoring

The NetGuardian is also an ideal way to migrate your existing dial-up sites to LAN-based monitoring. Sites that are currently monitored by legacy remotes using dial-up connections can be immediately upgraded to NetGuardians reporting over a dial-up connection. With the NetGuardian, these dial-up sites can be integrated with network-wide LAN-based monitoring, without adding new transport layers.

When LAN access is later added to the site, the NetGuardian can be easily switched to reporting over the LAN, with minimal provisioning and without disconnecting alarm inputs. The dial-up path can be retained as an emergency backup in case of LAN failure.
