Alternatively, you can use Telnet to locally access the TVP-221H, if you are under a router or switch and the TVP-221H and your computer are in the same network segment.

To access the TVP-221H Gateway from a remote location / or from the same LAN Segment using Telnet, perform the following tasks:

Type in “ping xxx.xxx.xxx”, where xxx.xxx.xxx is your ISP provided DNS Server IP or any known Public Internet Address. The following dialogue confirms Internet Access
