Features
Class of Service (COS)
Description Each extension, trunk, SUfEf?SETtelephone, dataset, ACD Position, or
console is assigned a Class Of Service (COS) which defines the features
available for that device. All devices with the same COS (which defines
the COS Options) have access to the same features. Fifty Classes Of
Service are available in the system to provide 50 different levels of fea-
ture accessibility. Each COS can have a name associated with it. COS
names are not available with Generic 1001 and Generic 1402.
In
the default database, all
devices belong to COS 1.
Conditions
The following conditions apply to this feature:
Several COS options are mutually exclusive; these are identified with
the description of each feature.
The COS may change temporarily for a caller through Verified Account
Codes (Travelling Class Marks).
The COS used is sometimes that of the caller and sometimes that of
the called party. Check the feature to determine whose COS is used.
LDNs
do not have a COS. The COS
for an LDN is determined from the
lowest Bay/Slot/Circuit PLID of
the console where
the LDN is
pro-
grammed.
Logical lines
do not have a COS. The COS is determined from the first
SUPERSETtelephone on which it is programmed. See Logical Lines.
Programming
Assign the desired features to each COS via CDE
Form 03 (COS Define).
Assign a COS to each console, extension, Dial-In Trunk, Non Dial-in Trunk,
dataset, and ACD position via CDE Forms 07,09, 12, 14, 15,39 and 40.
Operation None.
