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.
