Authorization Codes
Authorization codes are used on particular calls to temporarily raise a telephone’s 
Facility Restriction Level. This is useful for those who make calls from telephones 
other than their own or from outside the network. If a call you dial is blocked 
because the telephone’s Facility Restriction Level is too low, you can enter your 
authorization code. If the Facility Restriction Level associated with the 
authorization code is equal to or higher than the Facility Restriction Level of the 
trunk facilities required to place the call, the call is then completed. Up to 5000 
(csi/si) or 90000 (r) different authorization codes can be provided for your system 
at any one time. Authorization codes can be from 4 to 13 digits long. Using the 
system’s management tools, you can assign authorization codes and change their 
associated Facility Restriction Level and network access permissions.
Auto Start and Don’t Split
Allows the attendant to make a telephone call without pushing the start button 
first. If the attendant is on an active call and presses digits on the keypad, the 
system automatically splits the call and begins dialing the second call. The Don’t 
Split feature deactivates the Auto Start feature and allows the sending of touch 
tones over the line for the purposes of such things as picking up messages.
Automated Attendant
Automated Attendant (formerly known as Direct Access Calling) uses call 
vectoring commands to allow a caller to enter the extension of the party or 
department the caller wishes to reach. The call is routed to that extension by the 
vector.
Automatic Callback
Allows internal users who placed a call to a busy or unanswered internal 
telephone to be called back automatically when the called voice terminal becomes 
available.
When a user activates Automatic Callback, the system monitors the called 
telephone. When the called telephone becomes available to receive a call, the 
system originates the Automatic Callback call. The originating party receives 
priority ringing. The calling party then lifts the handset and the called party 
receives the same ringing provided on the original call. 
Automatic Circuit Assurance
Assists in identifying possible trunk problems. The system maintains a record of 
the performance of individual trunks and automatically calls a designated user 
when a possible failure is detected. This feature provides better service through 
early detection of faulty trunks and consequently reduces out-of-service time.

Features 
A-12 Basic features 
A
Automatic Incoming Call Display
Displays information about an incoming call even if the telephone is already in 
use.
Automatic Transmission Measurement System
Measures voice and data trunk facilities for satisfactory transmission 
performance. The measurement report contains data on trunk signal loss, noise, 
signaling return loss, and echo return loss. Acceptable performance, the 
scheduling of tests, and report contents are administrable.
Barrier Codes
A security code used with Remote Access to prevent unauthorized access to your 
system. To increase your system’s security, use a 7-digit barrier code with Remote 
Access Barrier Code Aging. A barrier code automatically expires if an expiration 
date or number of accesses has exceeded the limits you set. If both a time interval 
and access limits are administered for a barrier code, the barrier code expires 
when one of the conditions is satisfied.
NOTE:
Barrier codes are not tracked by Call Detail Recording (CDR). Barrier codes 
are incoming access codes, whereas, authorization codes are primarily 
outgoing access codes.
Bellcore Calling Name ID
Allows the system to accept calling name information from a local exchange 
carrier (LEC) network that supports the Bellcore calling name specification. The 
system can send calling name information in the format if Bellcore Calling Name 
ID is administered. The following Caller ID protocols are supported.
nBellcore (default) - US protocol (Bellcore transmission protocol with 212 
modem protocol)
nV23-Bell - Bahrain protocol (Bellcore transmission protocol with V.23 
modem protocol).
Block Collect Call
Blocks collect calls on class-of-restriction basis. This feature is available for any 
switch that uses the Brazil country code. If enabled for a station, all trunk calls that 
terminate to the station will send back a double answer to the CO. This double 
answer tells the CO that this particular station cannot accept collect calls. The CO 
then tears down the call if it is a collect call
.

Features 
A-13 Basic features 
A
Bridged Call Appearance — 
Multi-Appearance Telephones
Allows calls to be handled from more than one telephone. A bridged call 
appearance is set up by administering a primary extension and the button number 
associated with it on a two-lamp button on another telephone. One way this 
feature is most often used is by secretaries or assistants who answer or handle 
calls to the primary extension (an executive, for example). When the primary 
extension receives a call, the bridged call appearance flashes or rings, and the 
call can be handled as if the primary extension user was answering it. You can 
have up to 64 bridged call appearances.
Bridged Call Appearance —
Single-Line Telephones
Allows single-line telephones to have a bridged appearance on a 
multi-appearance phone. You can have up to 64 bridge call appearances.
Bulletin Board
The bulletin board is a place on the switch where people can post information and 
receive messages from other switch users, including Lucent Technologies 
personnel. Anyone with appropriate permissions can use the bulletin board for 
everyday messages. In addition, Lucent Technologies personnel can leave 
high-priority messages, which are displayed on the first ten lines of the bulletin 
board.
Busy Verification of Terminals and Trunks
Allows attendants and users of multi-appearance telephones to make test calls to 
trunks, telephones, and hunt groups to check the status of an apparently busy 
resource. With this feature, an attendant or multifunction telephone user can 
distinguish between a telephone that is truly busy and one that only appears busy 
because of some problem. Users can quickly identify faulty trunks.
Call Charge Information
The system provides two ways to know the approximate charge for calls made on 
outgoing trunks:
nAdvice of Charge — For ISDN trunks
Advice of Charge (AOC) collects charge information from the public 
network for each outgoing call. Charge advice is a number representing the 
cost of a call; it is recorded as either a charging or currency unit.

nPeriodic Pulse Metering — For non-ISDN trunks
Periodic Pulse Metering (PPM) accumulates pulses transmitted from the 
public network at periodic intervals during an outgoing trunk call. At the end 
of the call, the number of pulses collected is the basis for determining 
charges. 
Call-charge information helps you to account for the cost of outgoing calls without 
waiting for the next bill from your network provider. This is especially important in 
countries where telephone bills are not itemized. You can also use this information 
to let employees know the cost of their phone calls, and to encourage them to 
help manage the company’s telecommunications expenses. 
NOTE:
This feature is not offered by the public network in some countries, including 
the United States.
Call Coverage
Provides automatic redirection of calls that meet specified criteria to alternate 
answering positions in a Call Coverage path. A coverage path can include any of 
the following: a telephone, an attendant group, a uniform call distribution hunt 
group, a direct department calling hunt group, an automatic call distribution hunt 
group, a voice messaging system, or a coverage answer group established to 
answer redirected calls.
In addition to redirecting a call to a local answering position, Call Coverage can be 
administered to do the following:
nRedirect calls based on time-of-day.
nRedirect calls to a remote location.
Call Detail Recording
Records detailed call information on incoming and outgoing calls for the purpose 
of call accounting and sends this call information to a call detail recording output 
device. You can specify the trunk groups and extensions for which you want 
records to be kept as well as the type of information to be recorded. You can keep 
track of both internal and external calls. This application contains a wide variety of 
administrable options and capabilities.
Call Forwarding
Call Forwarding provides four functions:
nCall Forwarding All Calls — Allows calls to be forwarded to an internal 
extension, external (off-net) number, an attendant, or an attendant group.

Features 
A-15 Basic features 
A
nCall Forwarding Override — Allows the user at the forwarded-to extension 
to override Call Forwarding and either initiate a call or transfer a call back 
to the forwarded-from extension.
nCall Forward Busy/Don’t Answer — Allows calls to be forwarded when the 
called extension is busy or when the call is not answered after an 
administrable interval. If the extension is busy, the call forwards 
immediately. If the extension is not busy, the incoming call rings the called 
extension, then forwards only if the call remains unanswered longer than 
the administered interval.
nCall Forwarding Off-Net — Allows calls forwarded off-net to be tracked for 
busy or no-answer conditions. The system brings the call back for further 
call-coverage processing if the Coverage of Calls Redirected Off-Net 
(CCRON) feature is active. This feature is particularly useful for 
telecommuters who can have their on-site office calls forwarded to their 
home offices.
Call Park
Allows users to put a call on hold and then retrieve that same call from any other 
telephone on the system. This is helpful when a user is on a call and needs to go 
to another location for information. It also allows a user to answer a call from any 
telephone after being paged. 
Call Pickup
Along with Directed Call Pickup, allows a user to answer calls for other telephones 
within a specified call pickup group. Directed Call Pickup allows a user to pick up 
any call on the system. With this feature, users do not have to leave their location 
to answer a call for a nearby telephone. The user simply dials an access code or 
presses a Call Pickup button.
Call Pickup — Group
Allows you to answer a call that is ringing in a different call pickup group than your 
own. This feature is ideal if you work in an open office environment and have a 
need to answer phones ringing in a different group. You dial a facilities access 
code (FAC) and then a pickup group number to answer a call from a different call 
pickup group.
Call Timer
Automatically starts the local timer of a 6400-series telephone when a call is 
received. The timer stops automatically when the call ends, but is displayed for a 
few seconds. When a call is placed on hold, the timer continues to run but is not 
displayed. When the call comes off hold, the total elapsed call time displays.

Call Waiting Termination
Allows users of single-line telephones who are on a call to be notified of a second 
call. This feature enables the second call to wait and sends a distinctive call 
waiting tone to the user who is being called.
Calling/Connected Party Number Restriction
Per-Line CPN Restriction
Users may block the calling party number when originating calls. For ISDN calls, 
the Calling/Connected Party Number (CPN) Presentation Indicator is encoded 
accordingly. For non-ISDN calls to a public network that supports the CPN 
Restriction feature, the network specific Feature Activation Code is passed to the 
network for interpretation and activation.
If Per-Line CPN Restriction is administered for a station, it will override any ISDN 
trunk group administration for sending Calling Party Number.
Per-Call CPN Restriction
Users may indicate Calling Number privacy information. For ISDN calls, the CPN 
Presentation Indicator is encoded accordingly. For non-ISDN calls to a public 
network that supports the CPN Restriction feature, the network-specific Feature 
Activation Code is passed to the network for interpretation and activation.
If Per-Call CPN Restriction is activated for an outgoing call, it will override any 
Per-Line CPN Restriction administered for the calling station, and will override any 
ISDN trunk group administration for sending Calling Party Number.
Class of Restriction
Defines many different classes of call origination and termination privileges. 
Systems may have no restrictions, only a single class of restriction, or may have 
as many classes of restrictions as necessary to effect the desired restrictions. 
Many different types of classes of restriction can be assigned to many types of 
facilities on the switch. For example, you can use a calling-party COR to prevent 
callers from accessing the public network.
Class of Service
Defines whether telephone users can access the following features and functions: 
Automatic Callback, Call Forwarding, Data Privacy, Priority Calling, Restrict Call 
Forwarding Off-Net, Call Forward Busy/Don’t Answer, Personal Station Access, 
Extended Forwarding and Busy/Don’t Answer, Trunk-to-Trunk Transfer Restriction 
Override, Off-Hook Alert, Console Permission, or Client Room.

Code Calling Access
Allows attendants, users, and tie trunk users to page someone using coded chime 
signals. This feature is helpful for users who are often away from their telephones 
or at a location where a ringing telephone might be disturbing.
Conference — Attendant
Allows an attendant to set up a conference call for as many as six conferees, 
including the attendant. Conferences from inside and outside the system can be 
added to the conference call.
Conference — Telephone
Allows multi-appearance telephone users to set up six-party conference calls 
without attendant assistance. Single-line telephone users can set up three-party 
conference calls without attendant assistance.
Consult
Allows a covering user, after answering a call received through Call Coverage, to 
call and consult with the originally-called party. Consult can be used to let a 
covering user ask the called party if they want to speak with the calling party.
Controlled Restrictions
Allows an attendant or telephone user with console permission to activate and 
deactivate for an individual telephone or a group of telephones the following 
restrictions: outward, total, station-to-station, toll, and termination restrictions.
Coverage Callback
Allows a covering user to leave a message for the called party to call back the 
person who called.
Coverage Incoming Call Identification
Allows multi-appearance telephone users without a display in a Coverage Answer 
Group to identify an incoming call to that group.
Coverage of Calls Redirected Off-Net
Coverage of Calls Redirected Off-Net (CCRON) allows calls that have been 
redirected to locations outside of the switch to return to the switch for further 
processing. For example, an employee that telecommutes can have two coverage 
paths. One coverage path is used when in the office and the other coverage path

is used when working from home. The coverage path used from home would have 
a call to the employee’s work phone cover to his or her home phone. If the 
employee does not answer the call or is busy on another call, the call is redirected 
back to the switch for further processing, such as coverage to voice mail.
Crisis Alert
Visibly and audibly alerts attendant consoles, administered digital display stations 
or TransTalk telephones, or digital numeric pagers when an emergency call is 
placed. The feature indicates from where an emergency call is made (room or 
extension), which allows the attendant or other personnel to direct 
emergency-service personnel to the caller. Though often used in the hospitality 
industry, it can be set up to work with any standard attendant console, digital 
display station, or digital numeric pager.
Audible alerting sounds like an ambulance siren. Visual alerting consists of 
flashing of the crisis-alert button lamp and display of the caller name and 
extension. When crisis alerting is active, the console or station is placed in 
position-busy mode so that other incoming calls can not interfere with the 
emergency call notification. The console or station can still originate calls to allow 
notification of other personnel. Once a crisis alert call has arrived at a console, the 
console user must press the position-busy button to unbusy the console, and 
press the crisis-alert button to deactivate audible and visual alerting.
Customer-Provided Equipment Alarm
Provides you with an indication that a system alarm has occurred and that the 
system has attempted to contact a service organization. A device that you 
provide, such as a lamp or a bell, is used to indicate the alarm situation. You can 
administer the level of alarm about which you want to be notified.
Data Call Setup
Enables the setting up of data calls using a variety of methods such as keyboard 
dialing, telephone dialing, Hayes command dialing, permanent switched 
connections, administered connections, automatic calling unit interface, and 
hotline dialing. Data Call Setup is provided for both DCP and ISDN-BRI 
telephones.
Data Hot Line
Provides for automatic placement of a data call when the originator hangs up. 
Data Hot Line may be used for security purposes. This feature offers fast and 
accurate call placement to commonly-called data endpoints. Data terminal users 
who constantly call the same number can use Data Hot Line to automatically 
place the call when they hang up the telephone.

Data Privacy
Protects analog data calls from being disturbed by any of the system’s overriding 
or ringing features. Data Privacy is activated when a user dials an activation code 
at the beginning of the call.
Data Restriction
Like Data Privacy, this feature protects analog data calls from being disturbed by 
any of the system’s overriding or ringing features. It is administered at the system 
level to selected analog and multi-appearance telephones and trunk groups.
Default Dialing
Provides data terminal users who dial a specific number the majority of the time 
with a very simple method of dialing that number. This feature enhances Data 
Terminal (Keyboard) Dialing by allowing a data terminal user to place a data call to 
a preadministered destination in several different ways, depending on the type of 
data module. Data Terminal Dialing and Alphanumeric Dialing are unaffected.
Demand Print
Allows a user to print undelivered messages without calling the Message Center.
Dial Access to Attendant
Allows a user to reach an attendant by dialing an access code. The attendant can 
then extend the call to a trunk or to another telephone.
Dial by Name
Allows a caller to “dial” someone by entering their name from their touch-tone 
keypad. This feature is accessible by using the Call Vectoring feature and the 
integrated announcement circuit pack (TN750C) to create an “auto-attendant” 
procedure in which one of the options allows callers to enter a person’s name 
instead of that person’s extension number. The system processes the name 
characters received, and, if a single match is found, the number is dialed 
automatically.
The Dial-by-Name feature is described in greater detail in Dial by Name on 
Page A.-53.

Features 
A-20 Basic features 
A
Dial Plan
The dial plan is the system’s guide to digit translation. When the system receives 
dialed digits, the system must know what to expect next based on the digits 
received so far. For example, if a user dials 4, the dial plan tells the system how 
many more digits to expect before the call is processed.
Dialed Number Identification Service
Displays, for a called party or answering position, the service or product 
associated with an incoming call. 
Directory
Allows users with display-equipped telephones to access the system database, 
use the touch-tone buttons to enter a name, and retrieve an extension number 
from the system directory. The directory contains the names and extensions 
assigned to all telephones on the system.
Distinctive Ringing
Helps users and attendants distinguish among various types of incoming calls by 
distinctive ringing patterns. Users can set up ringing patterns to indicate many 
different types of calls: for example, internal, external, and priority calls.
By default, internal calls ring with a one-burst pattern, external calls with a 
two-burst pattern, and attendant and priority calls with a three-burst pattern.
Dual DCP I-Channels
Support the use of dual DCP I-channels for AUDIX networking. In this case, 
networking refers to the ability to send data files between AUDIX systems, not to 
communications with the switch.
Emergency Access to the Attendant
Provides for emergency calls to be placed to an attendant. These calls can be 
placed automatically by the system when a user leaves a telephone off-hook, or 
can be dialed by system users. Emergency access calls can receive priority 
handling by the attendant.
Enhanced Abbreviated Dialing
Supplements Abbreviated Dialing by providing one enhanced number per system. 
Enhanced number lists can contain any number or dial access code. System 
Administrators designate privileges for group number lists, system number lists,
