Tools that restrict unauthorized outgoing calls
Issue 9 May 2003

Facility restriction level
Facility restriction levels (FRLs) provide up to eight levels of restrictions (0 through
7) for users of AAR/ARS/WCR. FRLs identify where calls can be made and what
facilities are used. If the FRL of the originating facility is greater than or equal to
the FRL of the route pattern selected, the trunk group is accessible. The lower
number FRLs are the most restrictive for stations; FRL 0 can be implemented to
provide no outside access.
NOTE:
ARS/WRC route patterns should never be assigned an FRL of 0 (zero).
The FRL is used by AAR/ARS/WCR to determine call access to an outgoing trunk
group. Outgoing call routing is determined by a comparison of the FRLs in the
AAR/ARS/WCR routing pattern with the FRL associated with the originating
endpoint.
Authorization codes provide users with an FRL value high enough to give them
the calling privileges they require. Only users who enter a valid authorization code
with the appropriate calling privileges can override the lower FRL to gain access
to a long distance destination.
NOTE:
FRLs are not used if trunk groups have dial access allowed.
Alternate facility restriction levels
For DEFINITY G2, G3r, and System 85, this tool is used with or without
authorization codes to replace originating FRL values (the COS FRL versus the
AAR/ARS/WCR pattern preference FRL) with an alternate set of values. This
allows FRLs to be set to a lower value outside of normal business hours so more
restrictions are placed on after-hours calling.
NOTE:
A button is assigned to the attendant console to activate alternate FRLs.
Toll analysis (G3 only)
For Communication Manager, MultiVantage™ Software, DEFINITY ECS and
DEFINITY G3, the Toll Analysis screen allows you to specify the toll calls you want
to assign to a restricted call list (that is, disallowed), such as 900 numbers, or to
an unrestricted (that is, allowed) call list, such as an out-of-area number to a
supplier. Call lists can be specified for CO/FX/WATS, TAC, and ARS calls, but not
for tie TAC or AAR calls.
