Class Of Service (COS)
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 processing sys-
tem applications, 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.
System speed-dial numbers can be programmed to bypass COS restrictions on a system-wide
basis. If the option is not enabled, all system speed-dial numbers are subject to toll restriction.
Because a condition may exist where a critical or life threatening situation needs to be
reported, using the Emergency Call feature code will override all toll restrictions and trunk
access programming.
Note that if the trunk group is “not subject to toll restriction,” neither the trunk group or station
COS is checked, unless the call was placed using ARS. All ARS calls are subject to
station toll
restriction only.
The first nine COS designations (01-09 or 01-07) have default values. COS designations (10-
16 or 8-16) do not have default values and are blank. All of the classes of service are program-
mable. 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.
The default values of COS are indicated in the following table..
Table 23.
Class of Service Default Values for U.S. Systems
COS NAME RESTRICTION
01 ARS Only (This is a station class of service only. It is not used for trunk
groups. Also, the Automatic Route Selection premium feature is
required.)
Calls can only be placed using the Automatic Route
Selection (ARS) feature. The user will hear reorder tones when
attempting to place a call using any other method. A restricted
user can still select individual trunks if the trunks are designated
as “exempt from ARS Only” (as described on
page 161 ), were
transferred, were placed on hold, or are recalling or ringing. Trunk
restriction determines which trunks in the ARS route group can
be selected by the station or application.
02 Deny Area/
Office This restriction is divided into eight user groups to allow the use
of varying area/office code restriction tables. This is useful for
reducing restrictions for some of the stations, applications, or
trunk groups while increasing restrictions for others. Each station,
application, and trunk group is assigned a day mode and a night
mode user group in Database Programming. Within each user
group, area codes can be designated as restricted, allowed, or
extended. Restricting an area code prevents users from placing
calls to that area code. Allowing an area code allows all office
codes within that area code. Designating an area code as
extended allows the programmer to determine which office codes
(up to 800) are allowed or restricted within that area code.
03 Deny
Operator Calls to operator numbers are restricted.
