For absorption, this field defines how many digits will be absorbed. The
switch will remove the first 2 digits from the digit strings delivered with
incoming calls. For example, if the central office delivers the string
“556-4444,” DEFINITY ECS will change it to “64444,” an extension that
fits your dial plan.
4. In the Expected Digits field, type
7.
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.

Administering answer detection
Use this procedure to administer an outgoing or two-way trunk group for network
answer supervision or answer supervision by timeout. If your network supplies
answer supervision to a trunk group, you can administer DEFINITY ECS to
recognize and respond to that signal. If your network does not supply answer
supervision, you can set a timer for all calls on that group. When the timer expires,
the switch assumes the call has been answered and call detail recording starts (if
you’re using CDR).
For information about answer detection by call classification, contact your Lucent
representative or refer to ‘‘
Answer detection’’ on page 1141 for an introduction.
Before you start
Determine whether the trunk group receives answer supervision from your service
provider or private network. For example, most loop-start CO, FX, and WATS
trunks do not provide answer supervision.
