Group assignment 
 


Settings | Classes of service | Group assignment
 
Group assignment supports the ITR (Internal Traffic Restriction) feature, which allows you to determine which communication system stations can connect to which other communication system stations. You can also determine which trunks each station can access for both incoming and outgoing calls. To use this feature, the appropriate codes must be entered here and also in the CON matrix mask.
This function (which is also known as the Tenant Service) is implemented in two steps:

Step #1: Forming Groups  
Group assignment is used to assign an ITR connection group to the individual stations and trunks in the communication system. Later, when you code the Connection Matrix (Con matrix) you can refer to these groups to determine which stations can connect to which other stations and which stations can access which trunks.
You can create a maximum of 16 groups for stations and trunks together. With these groups, if you assign a trunk and a station to Group 6, they will be in the same group.
The default is Group 1 for both stations and trunks. The default connection for Group 1 is unlimited access, which means that all stations can connect to all other stations, and all stations have unlimited access to all trunks for both incoming and outgoing calls.

Step #2: Creating the Matrix  
CON matrix is used to create a connection matrix.

Stations, Trunks tables 
Stations and trunks can be divided into up to 6 16 traffic restriction groups (ITR groups).

9.7.5.2  

SDS groups table 
Every ITR group is assigned a range of speed dialing system numbers. If a user selects a speed dialing system number, the system determines whether or not this user is authorized to select that speed dialing system number by determining the associated ITR group. The number is dialed if this speed dialing system number belongs to the range of speed dialing system numbers assigned to the relevant ITR group. An error message is issued if the speed dialing system number does not belong to the assigned group.
Speed dialing system number ranges can overlap in the ITR groups. Individual speed dialing system numbers may not be entered in the ITR groups and multiple speed dialing system number groups may not be entered in an ITR group.
