Call terminating facilities
Any of the following trunk types can serve as the termination point for an AAR or ARS call:
•
Tie trunk — excluding RLT, but including
Communications Services (EPSCS) access trunks
•
WATS
•
CO
•
FX
•
ISDN-PRI
Each of these outgoing trunk groups has an assigned COR that contains an FRL. However, this FRL is
never used in an AAR or ARS call. A terminating-side FRL for AAR/ARS calls is assigned in the route
pattern, not to the outgoing trunk group.
FRL guidelines
You assign the FRL to the trunk group within the route pattern. You can use the same trunk group in more
than one route pattern, and the same trunk group can have a different FRL in a different pattern. You can
assign the same FRL to more than one trunk group.
Be consistent in FRL assignments. For ease of assignments, always use FRL 0 or 1 for a trunk group that
everyone can access. If you use a range of 0–5 in one pattern, use the same range in another pattern if all
users can access the first-choice route.
Assign a COR with an FRL of 0 to a group of users to restrict them from making outgoing calls. Use any
other number for the FRL on your first choice route pattern. This denies access to any trunk group for the
users, because all trunk-group FRLs are greater than 0.
You assign FRLs for remote access users through the remote-access barrier codes. You can assign up to
10 barrier codes, each with its own COR and FRL. The simplest way to assign these FRLs is to duplicate
the on-premises FRLs, then relate the appropriate barrier code to users who need remote access.
Example
The following is an example of how FRLs can be assigned in a COR:
•
FRL0 — 911 access only
•
FRL1 — Local calls only
•
FRL2 — FRL1 plus home area-code calls using WATS
•
FRL3 — FRL2 plus use of local lines for all calls in the home area code
•
FRL4 — FRL3 plus calls to all the USA, using WATS only
•
FRL5 — FRL4 plus calls to all the USA, using local lines
•
FRL6 — FRL5 plus international calls
•
FRL7 — Reserved
