DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1.1 June 2000 Managing trunks 367 Setting up digital trunks 12 Enhanced DS1 administration 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.

DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1.1 June 2000 Managing trunks 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.

373 Inserting and absorbing digits
12
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.

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. 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. 5. Press ENTER to save your changes. Related topics Refer to ‘‘ Adding a DID trunk group’’ on page 355 for instructions on administering a DID trunk group. Refer to ‘‘ Adding a Tie or Access trunk group’’ on page 361 for instructions on administering a tie trunk group.
DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1.1 June 2000 Managing trunks 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. Related topics Refer to ‘‘ Answer detection’’ on page 1152 for detailed information about this feature.

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.
