Traffic Group Matrix 9

Traffic group discrimination defines which extensions and external lines are allowed to be connected to each other, for example in case of transmission constraints.

Command group 23 includes commands that define a “traffic group matrix”. This matrix states which groups are allowed to be connected to each other.

Every element in the matrix can be programmed. This means, for example, that it is possible to allow calls from group 2 to group 3 but stop calls from group 3 to group 2. The same traffic group matrix is used both for voice calls and data calls.

To complete the function, extensions and external lines must be given traffic group categories, see commands 0102 Traffic group and 1002 Traffic group.

Extensions and external lines with traffic group category 0 are always open for connection to all other extensions and external lines without discrimination.
