Source Validation Select the check box to enable (default) source validation for this

against this network ID. If you enable this field, route 
determination is disabled and the source default is enabled. 
Source Default  Select this check box to enable source default for this network 
ID. 
Only one network ID on each port can have this attribute. When 
enabled, this network ID represents the preferred IXC for user 
calls originating on this logical port.
Route 
Determination 
(for ATM)
Select this check box to enable route determination for this 
network ID. If you enable route determination, source validation 
is disabled and the adjacent network parameter becomes active.
Adjacent Network  Select this check box to enable adjacent network for this network 
ID. This information is used by billing. Only one network ID on 
each logical port can have this attribute. When enabled, this 
network ID is considered to be the adjacent network (as opposed 
to another network reachable through the actual adjacent 
network). This adjacent network ID will not be signaled from 
this logical port. 
Admin Cost

Enter an administrative cost between 0 - 65535 for this network
