to the link protocol you choose. To ensure proper operation, always refresh the page by clicking
View and then Refresh .
The link protocol you choose depends on the existing network or the service you buy from your
Internet services provider.
Admin Status Allows you to view and change the Admin Status for this interface.
The Admin Status settings determines if the IP address for this interface is included in the routing
table. The possible states for Admin Status are:
Up : The routing table contains entries for this WAN interface.
Down : The routing table does not contain entries for this WAN interface.
The default Admin Status is Up .
The routing table entries for unused network interfaces can cause routing issues. For this reason,
Nortel Networks recommends you disable the Admin Status on any WAN interface that is not
connected to the network.
To remove the routing table entries for this WAN interface, select Disable .
If you decide to use a WAN interface that has had the Admin Status disabled, you must enable
the Admin Status to add entries for this WAN interface to the routing table.

protocol. Your choice of protocol depends on the existing network or the service you buy
from your Internet service provider. Frame relay is the default link protocol. If you change
the link protocol the following message appears “Reminder! Previous setting requires
rebooting the system to take effect. Please reboot the system...” Click
OK .
Caution: Reboot the system
You must remember to reboot your system for the changes you made to the link protocol
