DEFAULT DDI NUM. TRANSLATOR
The default DDI number translator corresponds to DDI TRANSLATOR No. 0 (see DDI TRANSLATOR). The default DDI Translator object is required if multi-translation is not used (a single DDI translator is used).
Reminder:
The DDI TRANSLATOR is used to adapt the DDI numbers supplied by the public network to the internal numbering plan of the LOCAL NODE.
The DDI translators are used by the NUMBERING PLAN DESCRIPTION objects (attributes DDI number for calling party and DDI number for called party)

First External Number
The first external number of the range is the smallest number of the range of DDI numbers provided by the public operator.

Example:
Directory numbers reserved by the public operator : 9600 to 9699
First external number of the range : 9600

First Internal Number
The first internal number of the range is the smallest number of the managed node numbering plan from which the DDI calls are authorized.

Example :
First internal number of the range used for local dialing ; introduce 400 ( see example in the attribute "Range Size").

Range Size
This concerns the number of contiguous DDI numbers decoded for this node.

Example:
Directory numbers reserved by the public operator: 9600 to 9699
First external number of the range : introduce 9600
Range size : 100.

Unique Internal Number
Yes: all numbers received corresponding to this range are translated into a single number: the first of the internal range.
