Screen reference

ISDN trunk group 

This field indicates the TON/NPI encoding applied to CPN information modified 
by the CLI Prefix feature. This encoding does not apply to calls originating 
locally. The Numbering Format field on page 2 of this screen applies to calls 
originated from this switch.

If this field is blank, DEFINITY ECS passes on the encoding received in the 
incoming setup message. If the incoming setup message did not contain CPN 
information and digits are added, the outgoing message will contain these digits. 
If the Numbering Format field is blank in this case, the value defaults to pub-unk. 

If the Numbering Format field on page 2 of this screen is also administered as 

, the trunk group is modified to “unk-unk” encoding of the TON/NPI. 

Therefore, this field also must contain a value other than 

.

The values for this field map to the Type of Numbering (TON) and 
Numbering Plan Identifier (NPI) values shown below.
