Note 5: If the NARS and BARS features are equipped in the same switch but for different
customers, the highest parameter values apply to that switch. For example, if one customer has
NARS and another customer has BARS, the NARS parameters apply to the BARS customer.
Note 6: If the New Flexible Code Restriction (NFCR) feature is equipped in conjunction with
BARS or CDP, the number of available NCOSs is 8. With X11 release 13 and later, this number
is expanded to 100. NFCR is described in X11 features and services (553-3001-305).
Included as part of each NCOS group is a Facility Restriction Level (FRL)
number which ranges from 0 (low-privilege) to 7 (high-privilege). The FRL
is used by the SL-1 software to determine the alternate route selection choices
available for network call attempts by users within an NCOS group.
