Remote Access users can access the system’s features and services the same

Up to 10 Barrier Codes, each with its own COR (and FRL) can be assigned.  
Although the COR defines other restrictions, 10 Barrier Codes are enough to also 
provide a range of FRL assignments. Assignment of Barrier Code FRLs is the
