Features 
A-2 Automatic Routing features 
A
Automatic Routing features
Provides a variety of automatic-routing features for public and private networks. 
Automatic Alternate Routing (AAR) and Automatic Route Selection (ARS) are the 
foundation for these automatic-routing features. They route calls based on the 
preferred (normally the least expensive) route available at the time the call is 
placed. Generally, AAR routes calls over a private network, and ARS routes calls 
using the public network numbering plan. However, both AAR and ARS support 
public and private networks. You can use the other features listed in this section 
when you use AAR and ARS.
Automatic Alternate Routing
Automatic Alternate Routing (AAR) allows private network calls to originate and 
terminate at one or many locations without accessing the public network. When a 
user dials an access code and phone number, AAR selects the most desirable 
route for the call and performs digit conversion as necessary. If the first choice 
route is unavailable, another route is chosen automatically.
The numbers called using AAR are normally private-network numbers. However, 
users can call a public-network number, a service code, an international number, 
operator access code, or an operator-assisted dialing number. With AAR and 
Subnet Trunking, users have a convenient way to place international calls to 
frequently-called foreign cities. Such calls route as far as possible over the private 
network, and then access the public network. This saves toll charges and allows 
users to use your private network as much as possible.
Automatic Route Selection
Automatic Route Selection (ARS) routes public network calls on the most 
desirable (usually the most economical) trunking facilities available on your 
system when the call destinations are accessible through your public network.
The system supports up to 40 routing patterns. Each routing pattern consists of up 
to 16 routing preferences (types of facilities) set up in the order in which you want 
them checked when a call is placed. Typically, the least expensive facility will be 
first on the list; the most expensive will be last.
If Generalized Route Selection is not being used when a call is made, the system 
selects a routing pattern based on the digits dialed. The routing preferences in 
that pattern are checked in the order in which they were listed, and the first avail-
able facility is used to place the call. If no facility is available, the call can be 
queued until a facility becomes available.

Features 
A-3 Automatic Routing features 
A
AAR/ARS Overlap Sending
Overlap sending can be used on AAR and ARS calls that are routed over ISDN 
trunk groups. Overlap sending sends ISDN call-address information one digit at a 
time instead of all the address information going out in one block. This 
significantly decreases call setup time in countries with complex public-network 
numbering plans, and is most useful for tandemed calls. 
AAR/ARS Partitioning
Allows AAR and ARS to be partitioned into eight user groups within a single 
system and provides individual routing treatment for each of these user groups.
User groups share the same Partition Group Number, which indicates the choice 
of routing tables that are used on a particular call. Each Class of Restriction is 
assigned a specific Partition Group Number or Time-of-Day specification. 
Different classes of restriction may be assigned the same Partition Group 
Number.
Alternate Facility Restriction Levels 
Allows the system to adjust facility restriction levels or authorization codes for 
lines or trunks. Each line or trunk is normally assigned a facility restriction level. 
With this feature, alternate facility restriction levels are also assigned. Attendants 
can change to the alternates, thus changing access to lines and trunks. Users 
might want to use this feature to disable most long-distance calling at night, for 
example, to prevent unauthorized staff from making long-distance calls.
!CAUTION:
This feature may change the AAR and ARS routing preferences. Using it on 
tandem and tie-trunk applications affects entire networks. Calls that are part 
of a cross-country private network may be blocked.
Facility Restriction Levels and Traveling Class 
Marks
Allows certain calls to specific users, while denying the same calls to other users. 
For example, certain users may be allowed to use central office trunks to other 
corporate locations, while other users may be restricted to less expensive 
private-network lines. Up to eight levels of restriction may be administered for 
users of AAR and ARS.

Features 
A-4 Automatic Routing features 
A
Generalized Route Selection
Provides voice and data call-routing capabilities. It is used to select not only the 
least-cost routing, but also optimal routing over the appropriate facilities. It 
enhances AAR and ARS by providing additional parameters in the routing 
decision and maximizing the chance of using the right facility to route the call. 
Also, if endpoint incompatibility exists, Generalized Route Selection provides a 
conversion resource (such as a modem from a modem pool) to attempt to match 
the right facility with the right endpoint.
Look-Ahead Routing
Provides an efficient way to use trunking facilities. It allows the system to continue 
to try to reroute an outgoing ISDN-PRI call that is not completing. When the 
system receives a cause value that indicates congestion, Look-Ahead Routing 
tells the system what to do next. For each routing preference, you can indicate 
whether the next routing preference should be attempted or if the current routing 
preference should be attempted again.
NOTE:
This feature is not related to the Look-Ahead Interflow feature. The 
Look-Ahead Interflow feature is not supported on DEFINITY BCS nor 
GuestWorks.
Subnet Trunking
Subnet Trunking modifies the number dialed so an AAR or ARS call can route 
over different trunk groups that may terminate in switches with different dial plans. 
Subnet Trunking inserts digits, deletes digits, pauses, and/or waits for dial tone in 
digit outpulsing, as required, so calls route as follows:
nTo or through a remote switch
nOver Tie trunks to a private network switch
nOver CO trunks to the serving CO.
Subnet Trunking is required on calls routing to or through a remote switch, 
regardless of the call’s destination.
Time-of-Day Routing
Time-of-Day Routing allows you to select the most economical routing of ARS and 
AAR calls based on the time of day and the day of the week a call is made. Up to 
eight Time-of-Day routing plans may be administered, each scheduled to change 
up to six times a day for each day in the week.
With Time-of-Day Routing, your company can take advantage of lower calling 
rates during specific times. If your company has locations in different time zones, 
you can maximize the use of your public or private network facilities by utilizing

those facilities in the location that has the lowest calling rates at the particular time 
a call is made. You can also use this feature to change the routing patterns when 
an office is closed and to eliminate unauthorized calls. 
Basic features
The following features come standard with the system.
Abbreviated Dialing
Provides lists of stored numbers users can use to do the following:
nPlace local, long-distance, and international calls.
nActivate features.
nAccess remote computer equipment. 
Users dial the list number and the one-, two-, or three-digit number associated 
with the phone number the user wants. The number is then automatically dialed 
by the system. A frequently called number can be stored on an abbreviated 
dialing button that a user needs to press once to make the call.
Access Security Gateway
Access Security Gateway is an authentication interface used to secure the system 
administration and maintenance ports and/or logins on the system. Access 
Security Gateway employs a challenge/response protocol to confirm the validity of 
a user and reduce the opportunity for unauthorized access. Successful 
authentication is accomplished when the feature communicates with a compatible 
key. The challenge/response negotiation is initiated once an RS-232 session is 
established and a valid system login ID has been supplied by a user. The 
authentication transaction consists of a challenge, issued by the system and 
based on the login ID supplied by the user, followed by receipt of the expected 
response, which is supplied by the user.
Active Dialing
The 6400-series telephones have a dialing option that allows the set to send 
S-channel button codes when the user presses a number on the dial pad while 
on-hook. This allows the user to begin dialing without first going off-hook.

Features 
A-6 Basic features 
A
Administered Connections
Automatically establishes an end-to-end connection between two access or data 
endpoints based on administered attributes. This feature provides capabilities 
such as:
nAlarm notification, including an administrable alarm type and threshold
nAutomatic restoration of connections established over a Software-Defined 
Data Network
nISDN-PRI trunk group [service may be referred to as ISDN-PRI (AC/AE) 
Service]
nScheduled as well as continuous connections
nAdministrable-retry interval for failed connection attempts.
Administrable Language Displays
Allows the messages that appear on telephone display units to be shown in the 
language spoken by the user. These messages are available in English (the 
default), French, Italian, Spanish, or one other user-defined language. The 
language for display messages is selected by each user. The feature 
requires 40-character display telephones. 
Administrable Loss Plan
The Administrable Loss Plan provides the ability to administer signal loss and gain 
for telephone calls. To do this, switch endpoints are classified into 17 endpoint 
types, and the loss plan can be administered for trunks, stations, and personal CO 
lines. Loss values are in the range of 15 dB loss to 3 dB gain. Preset defaults are 
available and are based on country type.
Administration Without Hardware
Allows you to administer telephones that are not yet physically present on the 
system. This feature works the same as administration with hardware: when 
stations are moved, user-activated features such as Call Forwarding and Send All 
Calls are preserved and functional. This greatly facilitates the speed of setting up 
and making changes to the telephones on the system.
Alphanumeric Dialing
Allows users to place data calls by entering an alphanumeric name rather than a 
long string of numbers.

A-7 Basic features 
A
Alternate Operations Support System Alarm
Number
Allows you to establish a second number for the system to call when an alarmable 
event occurs. This feature is useful for alerting a second support organization, 
such as INADS or OneVision.
Answer Detection
For purposes of call-detail recording, it is important to know when the called party 
answers a call. The system provides three ways to determine whether the far end 
has answered an outgoing call. 
nNetwork Answer Supervision — The central office (CO) sends back a 
signal to indicate that the far end has answered the call. If a call has 
traveled over a private network before reaching the CO, the signal is 
transmitted back over the private network to the originating system. This 
method is extremely accurate, but is not available in the United States over 
CO, FX, or WATS trunks. 
nAnswer Detection — A call-classifier circuit pack detects tones and 
voice-frequency signals on the line and determines whether a call has 
been answered. This method is fairly accurate. 
nAnswer Supervision by Timeout — A timer is set for each trunk group. If the 
caller is off-hook when the timer expires, the system assumes that the call 
has been answered. This is the least accurate method. Calls that are 
shorter than the timer duration do not generate call records, and calls that 
ring for a long time produce call records whether they are answered or not. 
Attendant Auto-Manual Splitting
Allows an attendant to announce a call or consult privately with the called party 
without being heard by the calling party on the call. It splits the calling party away 
so the attendant can confidentially determine if the called party can accept the 
call.
Attendant Backup
Notifies backup attendants that the primary attendant cannot immediately pick up 
a call. It provides both audible ringing and visual alerting to backup stations when 
the attendant queue reaches its queue warning level. When the queue drops 
below the queue warning level, alerting stops. Audible alerting also occurs when 
the attendant console is in night mode, regardless of the attendant queue size.

Features 
A-8 Basic features 
A
Attendant Call Waiting
Allows an attendant to let a single-line telephone user who is on the phone know 
that a call is waiting. The attendant is then free to answer other calls. The 
attendant hears a call waiting ringback tone and the busy telephone user hears a 
call waiting tone. This tone is heard only by the called telephone user.
Attendant Calling of Inward Restricted Stations
A telephone with a Class of Restriction that is inward-restricted cannot receive 
public network, attendant-originated, or attendant-extended calls. This feature 
allows attendants to override this restriction.
Attendant Console
A digital call-handling station with push-button control used not only to answer and 
place calls, but also to manage and monitor some system operations.
Attendant Control of Trunk Group Access
Allows an attendant to control trunk groups and prevents telephone users from 
directly accessing a controlled trunk group. This allows the attendant to monitor 
the use of these trunk groups. By watching the lamps associated with the trunk 
groups, the attendant can determine if the number of busy trunks in a specific 
trunk group has reached a preset warning level and if all trunks in a specific trunk 
group are busy. The attendant can then handle other calls to these trunk groups 
accordingly.
Attendant Direct Extension Selection
with Busy Lamp Field
Allows the attendant to keep track of extension status — whether the extension is 
idle, busy, or has Send All Calls active — and to place or extend calls to extension 
numbers without having to dial the extension number. The attendant can use this 
feature in two ways: using standard Direct Extension Selection access, or using 
enhanced Direct Extension Selection access. 
If the user’s extension is idle, the lamp is dark. If the user is busy on a call, the 
lamp lights steadily. If the user has Send All Calls activated, the lamp flashes.
Attendant Direct Trunk Group Selection
Allows the attendant direct access to an idle outgoing trunk by pressing the button 
assigned to the trunk group. This feature eliminates the need for the attendant to 
memorize, or look up, and dial the trunk access codes associated with frequently 
used trunk groups. Pressing a labelled button selects an idle trunk in the desired 
group.

Features 
A-9 Basic features 
A
Attendant Display
Shows call-related information that helps the attendant to operate the console. 
Also shows personal service and message information. Information is shown on 
the alphanumeric display on the attendant console. Attendants may select one of 
several available display message languages: English, French, Italian, or 
Spanish. In addition, your company may define one additional language for use by 
users and attendants on their displays.
Attendant Intrusion (Call Offer)
Allows an attendant to enter an existing call to inform the person being called 
about a message or another call. If administered, an intrusion tone warns the 
callers that the attendant is breaking in on the call.
Attendant Override of Diversion Features
Allows an attendant to bypass diversion features such as Send All Calls and Call 
Coverage by putting a call through to an extension even when these diversion 
features are on. This feature, together with Attendant Intrusion, can be used to get 
an emergency or urgent call through to a telephone user.
Attendant Priority Queue
Places incoming calls to the attendant in an orderly queue when these calls 
cannot go immediately to the attendant. This feature allows you to define 12 
different categories of incoming attendant calls, including emergency calls, which 
are given the highest priority.
Attendant Recall
Allows users to recall the attendant when they are on a two-party call or on an 
Attendant Conference call held on the console. Single-line users press the Recall 
button or flash the switchhook to recall the attendant. Multi-appearance users 
press the Conference or Transfer button to recall the attendant and remain on the 
connection when either button is used.
Attendant Release Loop Operation
Allows the attendant to hold a call off the console if the call cannot immediately go 
through to the person being called. A timed reminder begins once the call is on 
hold. If the call is not answered within the allotted time, the call returns to the 
queue for the attendant. Timed reminders attempt to return the call to the 
attendant who previously handled it. Only when the original attendant is 
unavailable are calls returned to the queue.

Features 
A-10 Basic features 
A
Attendant Serial Calling
Enables an attendant to transfer trunk calls that return to the same attendant after 
the called party hangs up. The caller, after reconnecting with the attendant, can 
then be transferred to another station within the switch. This feature is useful if 
trunks are scarce and Direct Inward Dialing services are unavailable. An outside 
caller may have to redial often to get through because trunks are busy. Once 
callers get through to an attendant, they can use the same line into the switch for 
multiple calls. The attendant’s display shows if an incoming call is a serial call. 
Attendant Split Swap
Allows the attendant to alternate between active and split calls. This operation 
may be useful if the attendant needs to transfer a call, but first must talk 
independently with each party before completing the transfer.
Attendant Trunk Group Busy/Warning Indicators
Provides the attendant with a visual indication that the number of busy trunks in a 
group has reached an administered level. A visual indication is also provided 
when all trunks in a group are busy. This feature is particularly helpful in showing 
the attendant that the Attendant Control of Trunk Group Access feature needs to 
be invoked.
Audible Message Waiting
Places a stutter at the beginning of the dial tone when a telephone user picks up 
the phone. The stutter dial tone indicates that the user has a message waiting. 
This feature is particularly useful for visually impaired people who may not be able 
to see a message light. It is often used with telephones that have no message 
waiting lights, but may not be available in countries that restrict the characteristics 
of dial tones provided to users.
Audio Information Exchange Interface
AUDIX is a message-handling system for recording and distributing spoken 
messages or voice mail. Stored voice prompts guide users in creating, sending, 
retrieving, answering, saving, and forwarding spoken messages.
Several versions of AUDIX are available. DEFINITY AUDIX is comprised of a 
circuit pack resident in the switch. I
NTUITY AUDIX is external to the switch and 
connects to the switch by station lines and data links. AUDIX systems can also be 
networked through switches or through other AUDIX systems. The systems rely 
on a data link between the AUDIX adjunct on the switch and the other AUDIX 
systems.
