Class of Service
n Description
Class of Service (COS) sets various features and dialling options (called items) for extensions. The
system allows any number of extensions to share the same Class of Service. An extension can have a
different Class of Service for each of the Night Service modes. This lets you program a different set of
dialling options for daytime operation, night time operation and even during lunch breaks. An
extension's Class of Service can be changed in system programming or via a Service Code (normally
777).
Conditions
None
Default Setting
·
All extensions have Class of Service 1 in all Night Service modes.
·
See the Charts for the default settings of the individual options.
If changing Class of Service via Service Code:
·
An extension can use Service Code 777 to change another extension's Class of Service
(Program 20-13-28 = 1).
·
An extension automatically blocks another extension's attempt to change their Class of
Service via Service Code 777 (Program 20-13-28 = 0).
·
The default Service Code for this option is 777 (Program 11-11-24 = 777).
