Does Your Terminal Switch Support Outbound SSH Connections?

When you can’t establish a normal network connection with a remote network element, a terminal switch with outbound SSH capabilities can provide an invaluable tool to help get your network back up and running again. When your terminal switch supports outbound SSH connections, this allows you to contact the terminal switch via secondary network, dial-up modem or satellite modem and then establish an outbound SSH connection with remote network elements in order to invoke diagnostic and troubleshooting commands.

Essentially, outbound SSH capability allows you to use your secure local area network or intranet to communicate with remote network elements in cases where either your primary network is down, or the nature or location of the remote equipment site makes normal network communication impractical. When your primary network is down, outbound SSH allows you to communicate with remote devices via local area network or intranet in order to fix the problem that caused the network outage. In other cases, where it’s just not practical to run a network cable out to a network equipment site in the middle of nowhere (such as an network equipment site located on an oil rig or in an extremely remote equipment cabinet,) outbound SSH allows you to establish communication with network elements at remote sites in order to check status, change configuration parameters or perform other important maintenance tasks.



Outbound SSH connections are both reliable and secure; the same security and authentication features that normally protect access to your terminal switch also protect access to outbound SSH capabilities. WTI terminal switch products include features such as a user directory and callback security to protect unauthorized access via modem, plus support for authentication protocols such as TACACS+, LDAP and Kerberos to verify user identity for network access.

If you manage a network application that requires secure, reliable access to RS232 ports on remote servers, routers, firewalls and other network elements, WTI terminal switch products can provide an ideal solution. WTI terminal switch products are available in both 100-240 VAC and -48 VDC configurations, and with 8 to 40 serial RS232 ports for connection to console ports on remote network elements.
