When normal in band communication is not available, our TSM Serial Console Servers provide a convenient means to create secure, encrypted, outbound SSH connections to network devices via dial up. This means that even when you can't establish a normal network connection, you can still dial into the TSM via modem and create outbound SSH connections to allow communication with devices on your secure local area network or intranet.
If you need to communicate with a remote facility that doesn't have network access, such as an oil rig or remote equipment closet, the TSM allows you to establish a secure, encrypted connection via modem and then communicate with other devices at that location.
Outbound SSH capabilities also allow employees to log into the TSM from a remote location via modem, and then access files on their work computers, even when a network connection is unavailable or impractical.
Secure passwords and a dialback feature protect outbound SSH capability from unauthorized access via modem. In cases where outbound SSH capabilities are not needed or are undesirable, the feature can also be easily disabled via the TSM's Network Configuration menu.
