Toll Restriction
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.)
CLASS OF SERVICE (COS)
Each station and each trunk group that is “subject to toll restriction” is assigned toll restriction 
classes of service (COS) that restrict or allow certain dialing patterns on outside calls.
The classes of service (COS) are programmed individually for stations, Voice Processor appli-
cations, and trunk groups. There are separate COS designations for day and night modes. A 
station or trunk group can be completely unrestricted or can have any combination of the 
classes of service. 
The first nine COS designations (01-09) have default values. COS designations (10-16) do not 
have default values and are blank. All of the classes of service are programmable. Each may be 
specified as an “allowed” or “denied” class of service, dialing patterns can be programmed for 
each, and each can be assigned to stations and trunk groups as needed.
