Facility Restriction Levels are used to limit user calling privileges for incoming and outgoing calls. The 
Facility Restriction Level determines if a call attempt is permitted and which routes can be used or denied in 
the routing process. Eight levels of Facility Restriction Levels can be assigned to telephones, computers, and 
system management tools. DEFINITY ProLogix Solutions does not require the Facility Restriction Level to 
be in an ascending order when administered in the patterns or preferences through system management.

When a call is attempted, the system compares the Facility Restriction Level of the telephone with the 
Facility Restriction Level of the trunk routes available to complete the call. If the Facility Restriction Level 
of the telephone is equal to or higher than the Facility Restriction Level of trunks, the call is completed; if it 
is lower, the call is blocked on that preference and compared to the Facility Restriction Level of the next 
route available. If the call fails to match the Facility Restriction Level on the available preferences, the call 
may queue for the first available and compatible trunk group (equal to or higher).

DEFINITY ProLogix Solutions also provides a feature called Alternate Facility Restriction Levels that 
allows the attendant to change the Facility Restriction Levels on originating facilities temporarily to a 
different set of Facility Restriction Levels. It is used to grant users greater access to trunking facilities than is 
normally provided, such as when charges are lower during evening hours.
