Enable button.
• You can disable the transmission, but access will be automatically enabled after a
reboot of the IDU. To do this, click the Disable IDU Tx button. The return link will
remain disabled until you click the Enable IDU Tx button or the IDU is rebooted.
When you disable access to the return link, the SIT is automatically logged off.
The SIT makes use of three IP addresses.
• The ethernet IP address is the IP address on the ethernet interface port (see
1.4). This IP address and mask are used by the LAN (terrestrial network) connected
directly to the IDU.
• The satellite OAM (operation, administration and maintenance) IP address is the SIT
IP address on the satellite interface port. It is used for SIT management (OAM) pur-
poses.
• The satellite traffic IP address is used for IPSec tunnelling and for RADIUS authenti-
cation.
Use the Network Configuration page to view and modify these IP addresses.
The table below describes the parameters in the Network Settings section of the page.
