Refer to ‘‘
Trunk Group’’ on page 980 for information about setting Inband ANI 
on the trunk group form.
Outgoing Automatic Number Identification
Outgoing automatic number identification (ANI) applies to outgoing Russian  
multi-frequency (MF) ANI, R2-MFC ANI , and Spain  Multi Frequency Espana 
(MFE) ANI trunks only.
Use Outgoing ANI to specify the type of ANI to send on outgoing calls. You can 
define MF ANI (the calling party number, sent via multifrequency signaling) 
prefixes by class of restriction. This allows a switch to send different ANIs to 
different central offices.
For a tandem call that uses different types of incoming and outgoing trunks, the 
switch uses: 
nthe incoming trunk’s COR -assigned call type for Russian or R2-MFC 
outgoing trunks 
nARS call types for MFE outgoing trunks
Interactions
nAttendant Console
If an attendant extends a call, the attendant’s COR is used to select ANI.
nAuthorization Codes
The authorization code COR is not used to select the ANI. The extension’s 
ANI is used if an extension originates the call, and the ANI for the switch is 
used if the originating endpoint is an incoming trunk.
nBridged Call Appearance
A call from a bridged call appearance uses the ANI of the primary 
extension.
nCall Vectoring
The ANI of the originating party is used, not the ANI of the call vector, 
when a call vectoring route-to command routes a call over an outgoing 
trunk.

nDistributed Communications System (DCS)
In a DCS, the ANI sent to the CO is determined by the ANI for PBX on 
PBX_B, but the category sent to the CO is determined by the Category for 
MF ANI field on the Class of Restriction screen for the incoming DCS 
trunk or by the type of call.
nExpert Agent Selection (EAS)
The EAS agent’s login extension and COR is used to determine ANI.
nHunt Groups and Automatic Call Distribution (ACD) Splits
The phone’s extension and COR is used to determine ANI for a hunt group 
or ACD split.
nMultimedia Call Handling (MMCH)
For call origination, multimedia complexes use the COR assigned to their 
phones.
nPersonal Station Access (PSA)
For ANI, the PSA extension and COR overrides the phone’s extension and 
COR.
nRemote Access
A remote access barrier code COR is not used for ANI. The extension’s 
ANI is used if an extension originates the call, and the ANI for the switch is 
used if the originating endpoint is an incoming trunk.

Automatic routing — general
DEFINITY ECS automatically routes outgoing calls using the most preferred 
(normally the least expensive) route available at the time the call is placed. 
Generally, Automatic Alternate Routing (AAR) routes calls over a private 
network and Automatic Route Selection (ARS) routes calls using the public 
network numbering plan. However, both AAR and ARS support public and 
private networks.

AAR
AAR routes calls over private networks. When a user dials the AAR feature 
access code (normally 8 in North America) and phone number, AAR selects the 
least expensive route for the call in the private network and performs any digit 
conversion. If the first-choice route is not available, another route is chosen 
automatically. 
AAR routes private-network numbers, public-network numbers, service codes, an 
international number, operator access code, or an operator-assisted dialing 
number. AAR routes calls route as far as possible over the private network, and 
then accesses the public network. This saves long-distance charges and allows you 
to use your private network as much as possible.
ARS
ARS routes calls over the public network. When a user dials the ARS feature 
access code (normally 9 in the US and 0 outside of the US) and phone number, 
ARS selects the least expensive route for the call when there are one or more 
long-distance carriers or services. 
ARS, like AAR, routes private-network numbers, public-network numbers, 
service codes, an international number, operator access code, or an 
operator-assisted dialing number, and also routes to Inter-exchange carriers (IXC). 
These are your long-distance providers. 
You can route ARS calls to a variety of types of public-network and 
private-network trunk groups including Central Office (CO), Foreign Exchange 
(FX), Integrated Services Digital Network (ISDN), Tie, and Wide Area 
Telecommunications Service (WATS). See ‘‘
Managing trunks’’ on page 349 for 
more information.

AAR and ARS digit analysis default 
translations
Your switch contains built-in AAR and ARS Digit Analysis Default Translations. 
These default translations are used for call processing whether or not AAR or 
ARS is enabled on your switch. 
Any 7-digit dialed string that begins with any number 2 through 9 is processed as 
an AAR call. Exceptions are listed in the ARS Digit Analysis Default Translations 
Table. The translations shown on the ARS Digit Analysis Default Translations
 
table are displayed in sorted order (including additions) on each of the 8 possible 
ARS Digit Analysis Tables.
NOTE:
For service outside of North America, these defaults should be deleted. You 
can delete the defaults by entering 
change ARS analysis 0. Then use 
spaces to blank out all of the Dialed String entries.

Trunking facilities
DEFINITY ECS can serve as an electronic tandem network (ETN). An ETN is a 
network of privately-owned trunk and switching facilities that provide a 
cost-effective alternative to long-distance calling between locations. Each 
switching facility in an ETN has a unique private-network office code consisting 
of 1–8 digits.
Traveling Class Marks (TCM) represent the caller’s Facility Restriction Level 
(FRL) or the FRL of the caller’s access trunk group, and are sent with AAR and 
ARS numbers sent on ETNs. 1900555 11 11 deny fnpa

Routing with ISDN and overlap sending
You can turn on overlap sending to work 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. See 
ISDN-PRI Trunk Group and ISDN-BRI Trunk group screens for information on 
how to set up overlap sending.

The switch does not check the FRL on an AAR or ARS call that uses a 
privileged Abbreviated Dialing Group List.

1184 Barrier codes 
20
Barrier codes
A barrier code is a security code used with Remote Access  to prevent 
unauthorized access to your system.
Brief description
Each barrier code must have a Class of Restriction (COR) and Class of Service 
(COS) assigned. Remote Access has inherent risks; it can lead to large-scale 
unauthorized long-distance use. To increase your system’s security use a 7-digit 
barrier code with Remote Access Barrier Code Aging. You can administer 
Remote Access Barrier Code Aging to:
nLimit the length of time an access code remains valid and/or
nLimit the number of times an access code can be used
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.
You determine the barrier code length, the actual barrier code, and the barrier code 
expiration date on the Remote Access screen. You must administer expiration 
dates and access limits for each of the possible 10 barrier codes. If your system 
has more than 10 Remote Access users, they must share codes.
When you no longer need a barrier code, remove it from the system. Barrier codes 
should be safeguarded both by you and their users. If you use barrier codes for 
outside calls, change them often.
If barrier codes are administered, a special answer-back tone causes a calling 
modem to leave dial mode. A modem’s dialer is sometimes used to gain access 
(this tone also cancels echo suppressors in the network, preventing DTMF tones 
from breaking dial tone from a switch). Barrier codes can be used alone or with 
authorization codes.
Use the 
status remote-access command to view the status of a Remote Access 
barrier code.
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.

1185 Bridged Call Appearance 
20
Bridged Call Appearance
Bridged Call Appearance allows single-line and multiappearance telephone users 
to have an appearance of another user’s primary extension number. The bridged 
call appearance can be used to originate, answer, and bridge onto calls to or from 
the other user’s primary extension number.
An appearance of a telephone’s primary extension number at another telephone is 
called a bridged call appearance. A bridged call appearance can be used to 
originate, answer, or bridge onto an existing call to or from the primary telephone 
user’s extension number.
On single-line telephones, Bridged Call Appearance is used by going off-hook. 
On multiappearance telephones, Bridged Call Appearance is used by going 
off-hook and pressing the bridged appearance button. In both cases, the user is 
then bridged onto the primary telephone’s extension number and can handle calls 
on that extension number.
An incoming call rings the primary extension number’s telephone and all 
telephones that have a bridged call appearance of the telephone’s primary 
extension number. Each telephone is visually alerted for all bridged appearances 
on the telephone, but has the option of audible ringing.
On multiappearance telephones, a bridged call appearance can be assigned to any 
2-lamp button. It does not require the use of a regular call appearance.
A bridged call appearance can be used just like a regular call appearance for most 
features. For example, Conference, Transfer, Hold, Drop, and Priority Calling can 
be used from a bridged appearance, just as they are used from a regular call 
appearance.
You can administer a telephone with zero call appearances of its primary 
extension. In this way, a telephone can be administered to have only bridged 
appearances.
Extension administrable buttons and lamps for 
multiappearance telephones
You can administer the message lamp and some feature buttons to apply to a 
specified extension rather than the extension of the telephone they reside on.
nYou can administer the message lamp to light when messages are waiting 
for the extension specified on the Station screen. In this way, the bridged 
user’s telephone can be set up to indicate when messages are waiting for 
the primary extension.

1186 Bridged Call Appearance 
20
nYou can administer the call forwarding all calls and call forwarding 
busy/don’t answer buttons to activate Call Forwarding for any extension 
that is on the telephone, even if this extension is a bridged appearance. In 
addition, you can administer the lamp associated with the call forwarding 
button to track the call forwarding status of any extension. In this way, a 
bridged user can activate or deactivate Call Forwarding for all primary and 
bridged appearances of the extension from the bridged appearance 
telephone, and the bridged appearance telephone shows the call forwarding 
status of the specified extension.
nYou can administer the send all calls button to activate Send All Calls for 
any administered extension. The lamp associated with Send All Calls 
tracks the status of the administered extension. In this way, a bridged user 
can activate Send All Calls for the primary extension user.
Considerations for single-line telephones
nThe number of bridged call appearances allowed varies by system. See 
DEFINITY ECS System Description for those numbers. A bridging user 
cannot have more than one bridged appearance for a particular primary 
telephone. However, a multiappearance bridging user can have 
appearances of more than one analog telephone on their telephone (a 
multiappearance bridging user, by use of different buttons, can bridge onto 
several different primary telephones). 
nThe number of bridged appearances allowed on a multiappearance bridging 
user’s telephone is limited only by the number of 2-lamp buttons available 
on the telephone.
nIf the primary single-line telephone is correctly administered, but not in 
service, calls can still be placed by the bridging users, and received on the 
bridged appearances of the telephone. The primary telephone can be out of 
service for several reasons, such as an unplugged telephone, a nonexistent 
telephone system technician busyout command, etc.
nIf more than one user goes off-hook on a bridged appearance at the same 
time, only the user who was the first to go off-hook can dial.
nIf a bridging user is not active on a call, and bridges onto the appearance of 
an active call, the user is bridged onto the active call. If a multiappearance 
bridging user is active on a call, and bridges onto the appearance of an 
active call, the previously selected call is dropped and the user is bridged 
onto the active call.
nThe Privacy-Manual Exclusion feature can be activated by the bridging 
user only, while active on a call, to prevent accidental bridging of an active 
call.
