TOLL RESTRICTION
The following features provide toll restriction on the system. (They are described in further
detail in this section.)
•
Trunk Group Toll Restriction: Each trunk group can be designated as “subject to toll
restriction” or “not subject to toll restriction” in Database Programming. If subject to
toll restriction, station class of service is checked when the trunk group is selected for
placing an outgoing call. The exceptions to trunk group toll restriction are as follows:
— Emergency Call Feature: When the Emergency Call feature code is entered, the
designated trunk access code is used to seize a trunk and the programmed emer-
gency number is dialed regardless of any station or trunk group toll restrictions.
— Automatic Route Selection (ARS): Calls placed using ARS (except Emergency
Call feature calls) are always subject to toll restriction, regardless of the selected
trunk group’s toll restriction programming. Note that only the station’s COS is
checked; the trunk group’s COS is not.
— Network ARS Calls: When determining toll restriction for an ARS outgoing call,
the network checks the station toll restriction based on the database information
on the node on which the station resides, not the node that contains the trunk
which the system uses to place the call. The system does not check the trunk COS
for ARS calls.
•
Exemption From ARS-Only Restriction: Each trunk group may be designated as
“exempt from automatic route selection (ARS) only.” If exempt, station users with the
ARS-Only class of service can select the trunk group directly.
•
Absorbed Digits: Trunk groups that are subject to toll restriction can be programmed
to “absorb” (ignore) the first digit(s) dialed. This allows the system to handle the dialed
digits just as they would be by the local telephone company or PBX to which the sys-
tem is connected.
•
Station And Trunk Group Classes Of Service: Each station and trunk group can be
assigned one or more classes of service (COS) which can restrict or allow certain digit
patterns when an outside call is dialed. (Trunk group COS is not checked when ARS is
used.)
