Screen Reference
Digits
This field is used with the Digit Treatment field, and its meaning depends on the entry in that
field. If the Digit Treatment field is absorption, this field specifies how many digits are deleted.
If the Digit Treatment field is insertion, this field identifies the specific digits that are added.
Valid entries
1 to 5
Up to 4 digits,
including * and #
blank
Digit Treatment
Use this field to modify an incoming digit string (as on DID and tie trunks, for example) by
adding or deleting digits. You'll need to do this if the number of digits you receive doesn't match
your dial plan.
Valid entries
blank
absorption
insertion
If you enter absorption or insertion, then you must enter a value in the Digits field.
Disconnect Supervision-In
This field indicates whether Avaya Communication Manager receives disconnect supervision
for incoming calls over this trunk group. It appears when the Direction field is incoming or
two-way. (If the Direction field is outgoing, Communication Manager internally sets this field
to n.)
The entry in this field is crucial if you allow trunk-to-trunk transfers. (To allow trunk-to-trunk
transfers involving trunks in this group, this field must be y and the Trunk-to-Trunk Transfer
field on the Feature-Related System Parameters screen must be y).
