Ext Len
Specifies the number of digits the extension can have.
Ext Code
Allows for groups of extensions to be administered.
NOTE:
When 0 alone is entered, the Ext Len field must be 1 and the DDD number
must be 10-digits.
Trk Grp(s)
The switch generates the station’s identification number if there is an entry in the
Ext Code field, and this field is administered with the trunk group number
carrying the call.
Valid entries Usage
0
to 5 Corresponds to the extension lengths allowed by
the dial plan.
Valid entries Usage
0
to 9 The Ext Code can be up to 5-digits long depending on the Ext
Len field entry. The entry cannot be greater than the Ext Len
field entry. For example, in the case of a 4-digit Ext Len field
entry, an Ext Code of 12 is the equivalent of all extensions of
the screen 12xx, excluding any explicitly listed longer codes.
If a code of 123 is also listed, the 12 code is equivalent of all
extensions of the screen 12xx except extensions of the screen
123x. The coding precludes having to list all the applicable
12xx extensions.
