Introduction to the DEFINITY 
system
This section provides you with general information about the DEFINITY ECS 
and some of the system-wide functions. It explains how to understand your 
configuration, read and use your dial plan, and shows you how to make simple 
changes such as adding extension ranges. This section also explains how to assign 
feature access codes (FAC).
Understanding your configuration
At a very basic level, the DEFINITY ECS consists of hardware to perform call 
processing, and the software to make it run. You use the administration interface 
to let the system know what hardware you have, where it is located, and what you 
want the software to do with it. 
You can find out which circuit packs are in the system and which ports are 
available by entering the command 
list configuration all. There are variations on 
this command that display different types of configuration information. Use the 
help function to experiment, and see which command works for you.
1. To view a list of port boards on your system, type 
list configuration 
port-network 
and press RETURN.
The System Configuration screen appears.

18 Understanding your configuration 
2
The System Configuration screen shows all the boards on your system that are 
available for connecting phones, trunks, data modules and other equipment. You 
can see the board number, board type, circuit-pack type, and status of each board’s 
ports. The 
u entries on this screen indicate unused ports that are available for you 
to administer. These may also appear as 
p or t, depending on settings in your 
system.
You will find many places in the administration interface where you are asked to 
enter a port or slot. The port or slot is actually an address that describes the 
physical location of the equipment you are using. 
A port address is made up of four parts:
ncabinet — the main housing for all the switch equipment. Cabinets are 
numbered starting with 01.
ncarrier — the rack within the cabinet that holds a row of circuit packs. Each 
carrier within a cabinet has a letter, A–E.
nslot — the space in the carrier that holds an individual circuit pack. Slots 
are numbered 01-16.
nport — the wire that is connected to an individual piece of equipment (such 
as a phone or data module). The number of ports on a circuit pack varies 
depending on the type. 
So, if you have a single-carrier cabinet, the circuit pack in slot 06 would have the 
address 01A06. If you want to attach a phone to the 3rd port on this board, the port 
address is 01A0603 (01=cabinet, A=carrier, 06=slot, 03=port).

19 Understanding the dial plan 
2
Understanding the dial plan
Your dial plan tells your system how to interpret dialed digits. For example, if you 
dial 9 on your system to access an outside line, it is actually the dial plan that tells 
the system to find an external trunk when a dialed string begins with a 9.
The dial plan also tells the system how many digits to expect for certain calls. For 
example, the dial plan may indicate that all internal extensions are 4-digit numbers 
that start with 1 or 2.
Let’s take a look at an example dial plan so you’ll know how to read your system’s 
dial plan. The following figure shows an example of a simple dial plan.
If you look at the lower half of the Dial Plan Record screen, you see the First Digit 
Table. This table defines the dialing plan for your system.
The rows in the First Digit Table indicate what the system does when the row’s 
first digit is dialed. The columns indicate how long the dialed string will be for 
each type of call. For example, this dial plan shows that when users dial a 4-digit 
number that starts with 2, they are dialing an extension.
The first digit table may have any of the following codes:
nAttendant (attd) — Defines how users call an attendant. Attd access 
numbers can be any number from 0 to 9 and contain 1 or more digits. In our 
example figure, the system calls an attendant when users dial 0.

nDial access codes (dac)  — Allows you to use trunk access codes (TAC) 
and feature access codes (FAC) in the same range. For example, you could 
define the group 600–699 for DAC, which would allow both FAC and TAC 
in that range. Dial access codes can start with any number from 1 to 9 and 
contain up to 4 digits, * and #. In our example figure, dial access codes 
begin with 6 and must be 3 digits long, so this company can have a feature 
access code set to 633 and a trunk access code assigned to 634.
nExtensions (ext) — Defines extension ranges that can be used on your 
system. In our figure, extensions must be in the ranges: 1000–1999, 
2000–2999, and 5000–5999. 
nFeature access codes (fac) only — FAC can be any number from 1 to 9 and 
contain up to 4 digits. You can use * or #, but only as a first digit. In our 
example, this company can use *21 to activate a feature and use #21 to 
deactivate the same feature. Our example also shows that one FAC can be 
set to 9 (first digit 9, only one digit long).
nMiscellaneous code (misc) — these codes are used if you want to have 
more than one kind of code start with the same digit. Using a misc code 
requires that you also define a second digit table. Refer to 
‘‘Second Digit 
Ta b l e’’ on page 874 for information. Our example does not show this type of 
code.
Displaying your dial plan
You might want to take this opportunity to look at and interpret your own dial 
plan. To display your system’s dial plan:
1. Type 
display dialplan and press RETURN. 
Modifying your dial plan
It is easy to make changes to your dial plan. For example, let’s add a new range of 
dial access codes to the dial plan. We want to be able to assign both FAC and TAC 
in the 700–799 range.
1. Type 
change dialplan and press RETURN.
The Dial Plan Record
 screen appears.
2. Move the cursor to the 7th row in the 3rd column.
This field defines what the system does when users dial any number from 
700 to 799.
3. Type 
dac in the selected field.
4. Press 
ENTER to save your changes.

21 Adding feature access codes 
2
Adding extension ranges
You may find that as your needs grow you want a new set of extensions. Before 
you can assign a station to an extension, the extension must belong to a range that 
is defined in the dial plan. Let’s add a new set of extensions that start with 3 and 
are 4 digits long (3000–3999).
To add this set of extensions to the dial plan:
1. Type 
change dialplan and press RETURN.
The Dial Plan Record
 screen appears.
2. Move the cursor to the 3rd row in the 4th column.
3. Type 
extension in the selected field.
4. Press 
ENTER to save your changes.
Other options for the dial plan
You can establish a dial plan so that users only need to dial one digit to reach 
another extension. You can also establish a dial plan that allows users to dial, for 
example, three digits to reach one extension, and four digits to reach another. This 
is particularly useful in the hospitality industry, where you want users to be able to 
simply dial a room number to reach another guest. For more information, see 
‘‘Single-Digit Dialing and Mixed Station Numbering’’ on page 1487
. 
Adding feature access codes
As your needs change, you may want to add a new set of feature access codes for 
your system. Before you can assign a FAC on the Feature Access Code screen, it 
must conform to your dial plan.
In our example, if you want to assign a feature access code of 33 to Last Number 
Dialed, first you need to add a new FAC range to the dial plan.
To add a FAC range from 30–39:
1. Type
 change dialplan and press RETURN.
The Dial Plan Record screen appears.
2. Move the cursor to the 3rd row and the 2nd column.
3. Type 
fac in the selected field.
4. Press 
ENTER to save your changes.

Introduction to the DEFINITY system 
22 Controlling the calls your users can make and receive 
2
Changing feature access codes
Feature access codes (FAC) allow users to activate and deactivate features from 
their phones. A user who knows the FAC for a feature does not need a 
programmed button to use the feature. For example, if you tell your users that the 
FAC for the Last Number Dialed is *33, then users can redial a phone number by 
entering the FAC, rather than requiring a Last Number Dialed button.
Many features already have factory-set feature access codes. You can use these 
default codes or you can change them to codes that make more sense to you. 
However, every FAC must conform to your dial plan and must be unique. For 
more information about the dial plan, refer to ‘‘
Understanding the dial plan’’ on 
page 19.
Let’s try an example. If you want to change the feature access code for Call Park 
to *72:
1. Type 
change feature-access-codes and press RETURN.
The Feature Access Code
 screen appears.
2. Move the cursor to the Call Park Access Code field.
3. Type 
*72 in the access code field over the old code.
4. Press 
ENTER to save your changes.
If you try to enter a code that is assigned to a feature, the system warns you 
of the duplicate code and does not allow you to proceed until you change 
one of them.
Tip:
To remove any feature access code, merely delete the existing FAC and leave 
the field blank.
Controlling the calls your users can 
make and receive
The DEFINITY ECS provides several ways for you to restrict the types of calls 
your users can make, and the features that they can access. 
You use Class of Restriction (COR) to define the types of calls your users can 
place and receive. Your system may have only a single COR, a COR with no 
restrictions, or as many CORs as necessary to effect the desired restrictions. 
You will see the COR field in many different places throughout the DEFINITY 
system - when administering phones, trunks, agent logins, and data modules, to 
name a few. You must enter a COR on these screens, although you control the 
level of restriction the COR provides.

23 Controlling the calls your users can make and receive 
2
Strategies for assigning CORs
The best strategy is to make it as simple as possible for you and your staff to know 
which COR to assign when administering your system. You can create a unique 
COR for each type of user or facility, for example, call center agents, account 
executives, administrative assistants, WATS trunks, paging zones or data modules. 
You can also create a unique COR for each type of restriction, for example, toll 
restriction, or outward restriction. If you have a number of people who help you 
administer your system, using this method would also require the additional step 
of explaining where you wanted to use each type of restriction. See ‘‘
Class of 
Restriction’’ on page 1304 for more information. 
To find out what CORs are administered in your system already, type 
list cor. You 
can also display information for a single COR by typing 
list cor #. 
Allowing users to change CORs
You can allow specific users to change their class of restriction COR from their 
telephones using a Change COR feature access code. You can also limit this 
feature by insisting that the user enter a password as well as a feature access code 
before they can change their COR.
Before you start
nBe sure that Change COR by FAC field is set to y on the 
System-Parameters Customer-Options screen. Note that you cannot have 
both Change COR by FAC and Tenant Partitioning enabled.
nBe sure that each user (who you want to allow to change a COR) has a class 
of service with console permissions. For more information about console 
permissions, refer to ‘‘
Class of Service’’ on page 532.
Instructions
To allow users to change their own class of restriction, you must define a feature 
access code and can, optionally, create a password. For example, let’s create a 
change COR feature access code of *55 and a password of 12344321.
1. Type 
change feature-access-codes and press ENTER.
The Feature Access Code
 screen appears. 
2. Move the cursor to the Change COR Access Code field.
3. Type 
*55 in the access code field.
4. Press 
ENTER to save your changes.

Now we have to define the password.
5. Type

The Feature-Related System Parameters
 screen appears. 
6. Move to the Password to Change COR by FAC field and enter 
12344321.
This field determines whether or not the DEFINITY system requires the 
user to enter a password when they try to change their COR. Lucent 
recommends that you require a password. 
7. Press 
ENTER to save your changes.
Controlling the features your users 
can access
The DEFINITY ECS offers a wide range of features and functions. Some of these 
you can administer differently from one user to the next. For example, you can 
give one user a certain set of phone buttons, and the next user a completely 
different set, depending on what each person needs to get his/her job done. You 
decide on these things as you administer the phones for these individuals. Refer to 
‘‘
Managing phones’’ on page 37 for more information. 
You can also establish classes of service (COS) to control the switch features that 
users can access. For example, you can permit users to forwarding their calls, or 
restrict them from placing priority calls. Once you have set permissions for a class 
of service, you assign this COS to a user’s telephone or other device. 
Classes of service are very similar to classes of restriction. COR and COS do not 
overlap in the access or restrictions they control. Refer to ‘‘
Class of Service’’ on 
page 532 for more information.
Class of service and class of restriction give you great flexibility with what you 
allow users to do. If you are in doubt about the potential security risks associated 
with a particular permission, read further in this document, consult the BCS 
Products Security Handbook, or contact your Lucent representative.

25 System-wide settings 
2
System-wide settings
There are some settings that you enable or disable for the entire system, and these 
settings effect every user. You may want to look over the various System 
Parameters screens and decide which settings best meet the needs of your users. 
To see a list of the different types of parameters that control your system, type 
display system-parameters and press HELP. You can change some of these 
parameters yourself. Type 
change system-parameters and press HELP to see 
which types of parameters you can change. In some cases, a Lucent representative 
is the only person who can make changes, such as to the System Parameters 
Customer-Options screen. 
This chapter offers a few examples of how you establish these system-wide 
settings. The Screen reference
 contains explanations of each of the system 
parameters screens, and how to use them. 
Changing feature parameters
You can modify the system parameters that are associated with some of the system 
features. For example, you can use the system parameters to allow music to play if 
callers are on hold or to allow trunk-to-trunk transfers on the system.
Generally, Lucent sets your system parameters when your system is installed. 
However, you can change these parameters as your organization’s needs change. 
For example, let’s say that you are told that the number of rings between each 
point for new coverage paths should change from 4 to 2 rings.
To change the number of rings:
1. Type
 change system-parameters coverage/forwarding and press 
RETURN.
The System Parameters Call Coverage / Call Forwarding
 screen appears.

field, type 
2.
3. Press ENTER to save your changes.
Each phone in a Call Coverage path now rings twice before the call routes 
to the next coverage point. The Local Cvg Subsequent Redirection/CFWD 
No Ans Interval field also controls the number of rings before the call is 
forwarded when you use Call Forwarding for busy/don’t answer calls. This 
applies only to calls covered or forwarded to local extensions. Use Off-Net 
to set the number of rings for calls forwarded to public network extensions. 
Administering treatment for denied 
calls
You can administer your system to reroute denied calls to an announcement, the 
attendant, or to another extension. Intercept Treatment provides an intercept tone 
or a recorded announcement or routes the call to an attendant for assistance when 
calls cannot be completed or when use of a feature is denied.
Instructions
In this example, we want all outward restricted call attempts to route to an 
announcement, and incoming calls that are denied to route to the attendant. 
1. Add an announcement on extension 2040, and name the announcement 
Intercept Denied Calls. 
Refer to ‘‘
Adding announcement extensions’’ on page 367 and ‘‘Recording 
announcements’’ on page 368 for more information.
