CALLING RESTRICTIONS
Description
Designated voice and data terminals can be restricted from making certain types of calls.
Available restrictions are:
● Outward Restriction
● Toll Restriction
● Facility Access Restriction
● ARS Restrictions.
Note: Each of these restrictions is voice terminal oriented, not PDC oriented.
Outward Restriction:
When outward restricted, a station will be unable to place any outside calls. The station will
be able to answer incoming calls and place and receive inside calls. A station that is
outward restricted will be unable to use Automatic Route Selection to place external calls
except to the emergency numbers.
Toll Restriction:
Allows calls by restricted terminals to be made based on as many as the first six digits of
the number called (after the facility access code).
Toll restricted users can make outgoing
calls only to those numbers that are on the Toll Call Allowed (TCA ) Lists to which it has
access.
TCA entries must be in the form NXX or NPA-NXX (exactly three or six
characters. ) The system administrator can establish up to 4 individual lists. A list can
contain from 1 to 64 entries provided that the total of all four lists does not exceed 64. One
character
“.” can be specified as a wild card character in place of the last 1, 2, or 3-digits
(e.g., “NX.”, “N..”, or “...”
) of the NXX code, but not in the NPA code. When this character
is used, any character in the dialed number appearing in that position is acceptable. Those
stations assigned Toll Restriction Class 1 have access to all four TCA Lists; Class 2 stations
just lists 2 through 4, Class 3 stations just lists 3 and 4, Class 4 stations just list 4. The entry
of an area code followed by “...”
on a TCA List allows access to all office codes in that area.
To allow calls within a customer’s local area, individual office codes are entered; this allows
the customer to restrict toll calls within the local calling area. NPA-NXX entries allow
specific office codes to be called within an area.
Note, NPA only entries are not permitted
(use NPA-... ).
Note that stations that are toll restricted are only toll restricted on CO trunks (type 701 and
801 ) or when they use the ARS feature.
They will not be toll restricted when they dial
access (or button access) any other type of trunk (e.g., FX, WATS, or Tie trunks).
Facility Access Restriction:
Any station may be denied dial access to the local CO and/or to all other pooled facilities (as
a group). A station so restricted may only
dial access those facilities via the Automatic
Route Selection (ARS) feature.
In addition, each trunk (VI and V2) and Virtual Facility (V2 only) can be administered to
allow or restrict dial access.
If dial access is restricted, the trunk or Virtual Facility (V2)
may only be dial accessed via ARS.
