## Traffic Group Matrix

## Definition

The traffic group matrix is an aid for opening up or restricting traffic between different extensions and/or trunks in the system.

## Use

The traffic group matrix must be programmed if any of the following restrictions are required in the system.

- Extensions shall be prevented from calling groups of trunks, for example, a specific route
- Certain extensions shall be prevented from accepting calls from groups of trunks, or incoming trunks accessing outgoing trunks
- Prevention of calls between groups of extensions in hotels or when the PBX is shared byseveral companies (Tenant function)

## Operation

An extension who attempts to call a party who is blocked in the traffic group matrix meets congestion tone.

The display shows "BLOCKED" or "NB":

### Reading the number (amount) of open extensions

By entering a command, on a STANDARD- or EXECUTIVE Telephone or OPERATOR Console, it is possible to read off how many extensions in the system are open for traffic to the public network, and how many are restricted from connection to the public network.

1. From idle.

- Key command *93#.
- The display shows, e.g.:
  “TRUNK ACCESS OPEN:119 RESTR: 64”

1. Press Clear to return to idle state.

## Capacity

The traffic group matrix can handle a maximum of 16 groups of extensions and/or trunks.

## Limitations

Group 0 means that extensions/trunks possessing this category are always open for calls to all other extensions/trunks irrespective of their categories.

## Programming

### To program extensions in the traffic groups

On initiation of the system all extensions are assigned traffic category 0, which means that there are no traffic restrictions.

Which extensions are to be included in which traffic groups can be specified via programming.

If traffic is to be limited, it is necessary to assign one of the traffic categories 1-15 to the respective extensions.
