Normally, you can’t change the DS1 Circuit Pack screen unless you remove all 
related trunks from their trunk group. However, if the DS1 MSP field on the 
System-Parameters Customer-Options screen is 
y and you are assigned the 
associated login permissions, you can change some of the fields on the DS1 
Circuit Pack screen without removing the related trunks from their trunk group. 
The following enhanced DS1 administration login permissions must be assigned 
on the Command Permission Categories screen:
nThe Maintain Enhanced DS1 field must be y.
nThe Maintain Trunks field must be y.
nThe Maintain Switch Circuit Packs field must be y.
If you busy out the DS1 circuit pack, you can change the following fields: CRC, 
Connect, Country Protocol, Framing Mode, Interface, Interconnect, Line Coding, 
and Protocol Version. After changing these fields, you may also have to change 
and resubmit associated screens.
Matching field settings on different screens
For enhanced DS1 administration, some field values on the DS1 Circuit Pack 
screen must be consistent with those on other screens as shown in the table below. 
If you change field values on the DS1 screen, you must change the related fields 
on the other screens and resubmit them.

372 Removing trunk groups 
12
Removing trunk groups
There’s more to removing a trunk group than just executing the remove 
trunk-group command. If you’re using ARS, you must remove an outgoing or 
two-way trunk group from any route patterns that use it. If you’ve administered 
Trunk-Group Night Service buttons for the trunk group on any phones, those 
buttons must be removed or assigned to another trunk group.
Instructions
As an example, let’s remove trunk group 5. This two-way group is used in ARS 
route pattern 2. In addition, a Trunk-Group Night Service button on extension 
8410 points to this group.
To remove trunk group 5:
1. In the Route Pattern
 screen for route pattern 2, clear the entries for trunk 
group 5.
If you’re replacing trunk group 5 with another trunk group, just type the 
information for the new trunk group over the old entries. Remember to 
press 
ENTER to save your changes.
2. In the Station
 screen for extension 8410, clear the entry in the Button 
Assignments field for the Trunk-Group Night Service button.
Remember to press 
ENTER to save your changes.
3. In the Trunk Group
 screen for trunk group 5, remove all member trunks 
from the group.
Refer to ‘‘
Removing trunks from a trunk group’’ on page 371 for 
instructions.
4. Type 
remove trunk-group 5 and press ENTER.
The Trunk Group
 screen appears.
5. Press 
ENTER to remove the trunk group.

Inserting and absorbing digits
Use this procedure to modify the incoming digit string on DID and tie trunks by 
inserting (adding) or absorbing (deleting) digits. You’ll need to do this if the 
number of digits you receive doesn’t match your dial plan.
Instructions
As an example, let’s say you have a DID trunk group. It’s group number is 5. Your 
service provider can only send 4 digits, but your dial plan defines 5-digit 
extensions beginning with 6:
1. Type 
change trunk-group 5 and press ENTER.
The Trunk Group
 screen appears.
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.

375 Administering answer detection 
12
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 1152 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.
Instructions
As an example, we’ll administer trunk group 5 for both types of answer detection. 
To administer trunk group 5 for answer supervision from the network:
1. In the Trunk Group
 screen for group 5, type y in the Receive Answer 
Supervision field.
2. Press 
ENTER to save your change.
Now let’s administer answer supervision by timeout. We’ll set the timer to 15 
seconds. To administer trunk group 5 for answer supervision by timeout:
1. In the Trunk Group
 screen for group 5, type 15 in the Answer Supervision 
Timeout field.
2. Press 
ENTER to save your change.

376 Administering trunks for listed directory numbers 
12
Administering trunks for listed 
directory numbers
Listed directory numbers (LDN) are the phone numbers given for an organization 
in public telephone directories. You can administer DEFINITY ECS so that calls 
to different listed directory numbers go to the same attendant group. How you 
administer your system for LDN calls depends on whether the calls are coming in 
over DID and tie trunks or over CO and FX trunks.
Instructions
As an example, let’s say that one attendant group answers calls for 3 different 
businesses, each with its own listed directory number:
nCompany A — 855-2020
nCompany B — 855-1000
nCompany C — 855-1111
DID trunks and some tie trunks transmit part or all of the dialed digit string to the 
switch. If you want these calls to different numbers to go to one attendant group, 
you must identify those numbers for the switch on the Listed Directory Numbers 
screen.
Let’s take the 3 businesses listed above as an example. Let’s assume your switch 
receives 4 digits from the central office on a DID trunk group and that you’re not 
using Tenant Partitioning. To make these calls to different listed directory 
numbers terminate to your attendant group:
1. Type 
change listed-directory-numbers and press ENTER.
The Listed Directory Numbers
 screen appears.
