2. In the Digit Treatment field, type insertion.
This field tells the switch to add digits to the incoming digit string. These
digits are always added at the beginning of the string.
3. In the Digits field, type
6.
For insertion, this field defines the specific digits to insert. The switch will
add a “6” to the front of the digit strings delivered with incoming calls. For
example, if the central office delivers the string “4444,” DEFINITY ECS
will change it to “64444,” an extension that fits your dial plan.
4. In the Expected Digits field, type
4.
This field tells the switch how many digits the central office sends.
NOTE:
The Expected digits field doesn’t appear on the screen for tie trunk
groups.
5. Press
ENTER to save your changes.
If your service provider sends 7 digits but you only need 5, you need to absorb the
first 2 digits in the digit string. To absorb digits:
1. Type change trunk-group 5 and press
ENTER.
The Trunk Group
screen appears.
2. In the Digit Treatment field, type
absorption.
This field tells the switch to remove digits from the incoming digit string.
These digits are always removed from the beginning of the string.
3. In the Digits field, type
2.
