## 3305
Predigits for first alternative route

When all trunks between two exchanges are busy, the call can be sent via another exchange. An alternative route shall be defined for the call to be rerouted. Two different alternative routes can be defined. The first alternative route is defined with command 3304 First alternative route. The second alternative route is defined with command 3306 Second alternative route.

Command 3305 is used to define predigits (if any) for the first alternative route. Command 3307 Predigits for second alternative route is used to define predigits (if any) for the second alternative route. The predigits are transmitted before the dialled external number.

Predigits = 1-10

Example:

The extensions in exchange A have numbering scheme 2xxx. Exchange A has an outgoing route with access number 0 to the public network. The extensions in exchange B have numbering scheme 3xxx. Exchange B has public directory number 742 3000.

Tie lines exist between exchanges A and B. A fixed numbering scheme is used for calls between A and B.

If all tie lines between A and B are busy, calls are to be rerouted via the public network.

For the above to function the following programming shall be executed for the route with access number 3:

3303 |  | 3 predigit for normal route, i.e. fixed numbering scheme

3304 |  | 0 alternative route 1, i.e. outgoing route

3305 |  | 7423 predigits for alternative route 1

Valid Values: 0-10 digits
