Class Of Service - NEC Univerge SV8100 Features And Specifications Manual

UNIVERGE SV8100
Description
Class of Service (COS) sets various features and dialing 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
dialing options for daytime operation, nighttime operation and even during lunch breaks. An extension
Class of Service can be changed in system programming or via a Service Code (normally 677). There
are 15 available Classes of Service.
Conditions
Before assigning a new COS, make sure the new COS matches the old COS or you may

enable options, which the extension should not have or remove options, which it should
have.
An extension can have a different Class of Service for each Service mode. At default, the

Mode names are assigned as follows:
Mode 1 = No setting

Mode 2 = Night

Mode 3 = Midnight

Mode 4 = Rest

Mode 5 = Day2

Mode 6 = Night2

Mode 7 = Midnight2

Mode 8 = Rest2

If a user dials a number not programmed in ARS, Program 26-01-03 determines if the

system should route over the trunk group settings defined in Program 21-02 or play an error
tone.
When using ARS Class of Service, with Program 26-01-03 set to (1) "Play Warning Tone",

any trunk (except a CCIS trunk) pointed or transferred to a virtual that is Call Forward
Off-Premise will not complete. For a virtual to Call Forward Off-Premise, Program 26-01-03
must be set to "Route to trunk group" and the call will follow the trunk group settings of the
trunk, assigned in Program 21-03.
When using ARS Class of Service, with Program 26-01-03 set to (1) "Play Warning Tone",

a CCIS trunk pointed or transferred to a virtual that is Call Forward Off-Premise will always
follow ARS Class 1 routing properties.
