then be bridged onto by any of the brid ging users or by the primary terminal 
station user. After ringing ceases at the single-appearance terminal (primary or 
bridged) the terminal user has no indication of the call’s existence. In this case, if 
the terminal user did not hear the ringing, the user would not know of the 
existence of the call and could inadvertently p i ck u p on an active call.
NOTE:
See the Ringing — Abbreviated and Delayed feature for other bridged 
appearance alerting option.
A brid ged call appearance can be assigned to any two-lamp button. It does not 
require the use of a regular call appearance.
A brid ged call appearance can only be used to originate and/or answer calls on 
the primary terminal’s extension number, or to brid g e onto an active call. The 
bridging user cannot access a Call Waiting call or a call on hard or soft hold by 
the primary terminal user.
Because of the aforementioned restrictions, certain limitations are placed on the 
use of the Conference, Transfer, and Hold features for b oth the primary terminal 
user and the brid ging users. When more than one user is active on a call (that is, 
a primary terminal user and one or more bridging users; or two or more bridging 
users; or any configuration that has more than one bridging party on an 
established call), attempts to use the Conference, Transfer, or Hold features are 
denied.
When Call Waiting and/or Priority Call Waiting is assigned to the primary terminal, 
these features apply only when the primary terminal user is off-hook on a call. 
They are not active when the multi-appearance terminal user is off-hook on a call 
on the brid ged appearance of the primary terminal.
When a single-line primary or bridged appearance terminal user is off-hook on an 
active call, normal single-line Conference, Transfer, and  Hold procedures apply.
When a multi-appearance bridging or primary a ppearance user is off-hook on an 
active call on the primary terminal’s extension number, then normal 
multi-appearance terminal Conference, Transfer, and Hold procedures apply.
Sample Applications
The bridging of a primary terminal satisfies certain conditions that require 
handling a call from locations other than that of the primary terminal. Some of 
these situations are as follows: 
nA secretary placing calls for an executive(s)
These calls can be placed on hold for later retrieval by the executive, or 
the executive can simply bridge onto the call. In all cases, the executive 
handles the c all as if he or she had placed or answered the call. It is never 
necessary to transfer the call to the executive. 
						

							Feature Descriptions
3-298Issue  3   March 1996 
nA secretary taking care of details for an executive, such as a call to the 
finance department, traffic department, and so on (any call that requires 
automatic identification of the executive’s extension number).
A secretary can bridge onto an active call and take down information su ch 
as an address or telephone number.
nVisitor telephones
An executive may have another voice terminal in his or her office which is 
to be used by visitors. It may b e desirable that the visitor be able to bridge 
onto a call which is active on the executive’s primary extension number. 
G3V4 and later releases also allow for the administration of a single-line, 
analog terminal as a visitor phone with a b rid ged  appearance of a p rimary 
extension from the executive’s phone.
nService environments
It may be necessary that several people be able to handle calls to a 
particular extension number. For example, several users may be required 
to answer calls to a hot line numb er in a ddition to their normal functions. 
Each user may also b e required to bridge onto existing hot line calls.
nA user frequently using voice terminals in different locations
A user may not always spend time in the same place. For this type user, it 
is convenient to their extension number bridged at several different voice 
terminals.
Considerations
The primary terminal’s extension numb er can have an a p pearance on up to 
seven ‘‘bridging’’ user’s terminals for G3vs/G3s, and G3i, and 15 for G3r. 
(Bridging means other terminals bridged onto the call.) A bridging user cannot 
have more than one bridged appearance for a particular primary terminal. 
However, a multi-appearance bridging user c an have appearances of more than 
one analog terminal on their terminal (that is, a multi-appearance bridging user, 
by use of different b uttons, can bridge onto several different primary terminals).
The number of brid ged appearances allowed on a multi-appearance bridging 
user’s terminal is limited only by the number of two-lamp buttons available on the 
terminal.
If the primary single-line terminal is correctly administered, but not in service, 
calls can still be placed, by the bridging users, and received on the brid g ed 
appearances of the terminal. The primary terminal can be out of service for 
several reasons, such as an unplugged terminal, a non-existent terminal system 
technician busyout command, and so on.
If more than one user goes off-hook on a bridged appearance at the same time, 
only the user that was the first to go off-hook can dial. 
						

							Brid ged Call Ap pearance— Single-Line Voice Terminal
Issue  3   March 1996
3-299
If a bridging user is not active on a call, and bridges onto the ap p earance of an 
active call, then the user is bridged onto the active call. If a multi-appearance 
bridging user is active on a call, and bridges onto the a p pearance of an active 
call, then the p reviously selected call is dropped and the user is bridged onto the 
active call.
The 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.
If a call terminates at a voice terminal on an extension numb er other than the 
primary extension number (for examp le, Terminating  Extension Group, UCD 
Group, Call Coverage Answer Group, or DDC Group extension numb er), a 
bridged call a p pearance is not maintained. Therefore,  it  is recommended that 
the primary terminal not b e made a member of such a group (even though 
administration of this is not prohibited).
The Brid ged Call Ap pearance feature should not be considered as a 
replacement for Call Coverage or any other similar features.
If two parties are bridged together on an active call with a third party, and if the 
conference tone feature is enabled, the conference tone is heard.
Interactions
NOTE:
In the following description of interactions, the term ‘ ‘TE RM I N A L -B A SE D ’ ’ 
means that the feature applies to that user whether a call appearance or a 
bridged appearance is being used to activate/deactivate the feature. The 
term 
‘‘EXTENSION-BASED’’ means that activation/deactivation of the 
feature from a bridged appearance is seen by the system as having been 
made by the primary (single-line) terminal.
nAbbreviated Dialing
A user, accessing Ab breviated Dialing while on a bridged call 
appearance, accesses his or her own Abbreviated Dialing lists. The user 
does not access the Abbreviated Dialing lists of the primary extension 
associated with the brid ged call appearance.
nAttendant Display and Voice Terminal Display
A call from the primary extension number or from a bridged call 
appearance of the primary extension number is displayed as a call from 
the p rimary extension number (that is, the call is displayed as coming from 
the p rimary extension number regardless of which appearance placed the 
call).

nAuthorization (COR, FRL)
The COR (including restrictions and FRL) of the primary terminal are 
always used when authorization checking is required, even when the call 
is originated from a bridged appearance button by a bridging user.
nAutomatic Callback
Automatic Callback calls cannot originate from a brid g ed call 
appearance. However, when Automatic Callback has b een activated from 
the principal user’s terminal, the Callback call rings (with priority call 
distinctive ringing signal) at all bridged appearances of the extension as 
well as at the principal user’s terminal. Displays at all (p rincipal and 
bridged users) stations show that it is a Callback call.
nAutomatic Call Distribution (ACD) 
Brid ged appearances cannot be ACD members (although administrable), 
but can be used in multiple call situations.
nCall Coverage
When an analog station is administered as a  bridged call appearance, the 
terminal user cannot invoke Send All Calls for the extension of their voice 
terminal. The user does not have a Send All Calls button, and the call 
appearance is associated with another extension. When the user dials a 
Feature A c cess Code (FAC) Send All Calls is activated for the extension 
associated with the call ap pearance.
nCall Forwarding All Calls
Call Forward Busy/Don’t Answer
Call Forwarding c an be activated or canceled for the primary terminal 
number from the primary terminal or from any bridged call appearance of 
that number; then, when activated, calls to the primary extension number 
do not terminate at the principal or the bridged call appearances, but go 
to the designated forwarding destination. Bridged call appearances do 
not receive redirection notification of the call to the primary extension 
when it is forwarded unless Ringing-Abbreviated and Delayed is 
administered.
When an analog station is administered as a  bridged call appearance, the 
terminal user cannot invoke call forwarding for the extension of their voice 
terminal. The user does not have a call forwarding button, and the call 
appearance is associated with another extension. When the user dials a 
Feature A c cess Code (FAC) call forwarding is activate d for the extension 
associated with the call ap pearance.
nCall Park
Call Park is 
EX TENS IO N - B AS ED; when a call is parked from a bridged call 
appearance, it is parked on the primary terminal extension number.

Issue  3   March 1996
3-301
nCall Pickup
Calls to the primary terminal, alerting at bridged appearances of the 
primary terminal, can be picked up by member’s of the brid ging user’s 
Call Pickup group; this causes all bridged appearances of the call to be 
dropped.
Calls ringing at a primary terminal can be picked up by members of the 
primary terminal’s Call Pickup group. However, if the p rimary terminal and 
the bridging user’s terminal are not in the same Call Pickup group, then 
the bridging user cannot pick up calls to other members of the primary 
terminal’s Call Pickup group.
Originating on a bridged ap pearance and dialing the Call Pickup FAC is 
interpreted as an attempt to pick up a call from the primary terminal’s Call 
Pickup group.
A brid ging user can use Call Pickup to pick up a call that is alerting at a 
bridged appearance, instead of selecting the bridged appearance button. 
This causes the call at the primary terminal and all brid g ed a p pearances 
of the call to be dropped.
If the bridging user has appearances of numerous single-line (primary) 
terminals (for examp le, Sales, Service, Warehouse, and so on), and it is 
not desired that the calls be answered by anyone other than the primary 
terminal user or the brid g ing users, then the brid g ing user(s) should not 
be assigned to a pick up group.
nCall Waiting Termination
Call Waiting Termination a p plies only to an active call on the primary 
terminal which has no one else bridged on. If one or more bridging users 
are active on a call, Call Waiting calls are denied whether or not the 
primary user is also off-hook on the call. A bridging user cannot bridge 
onto a call with the primary user if there is also a call waiting.
nCall Detail Recording (CDR) 
If a bridging user originates and/or answers a call on a bridged 
appearance, the primary terminal is record ed as the calling/called 
terminal. A conference or transfer by a bridging user also a ppears as 
though it was performed by the primary terminal user.
nConference—Attendant
Conference—Terminal
A brid ged call cannot b e conferenced if more than one user is active on 
that call. This is because the bridging user has no access to the call after 
the primary terminal user places the call on soft hold, and the p rimary 
terminal user has no access to the bridging user’s call appearance used 
for conference/transfer attemp ts.
If a bridging user is active on a bridged call and the primary analog 
terminal user attemp ts a conference, the attempt is ignored. The same is 
true if an analog bridging user attempts a conference when the primary 
terminal user and another brid ging user is active on a call. 
						

							Feature Descriptions
3-302Issue  3   March 1996 
When the primary terminal user is active on a call, and no other bridging 
user is active on the call, then that call can be placed on hold by the 
primary terminal user utilizing normal single-line conference procedures. 
Any attempt by a brid ging user to bridge onto the call during a successful 
conference attemp t is denied.
A brid ging user, alone on a brid ged call, can conference the call utilizing 
the normal multi-appearance terminal conference procedures.  Any 
attempt by the analog primary terminal user to bridge onto the call during 
a successful conference attempt is ignored; any attempt by other bridging 
users is denied (standard denial response is returned to the bridged 
appearance).
If a conference is not allowed because of the preceding limitations, the 
user can accomplish a transfer by asking an internal non-bridged party in 
the c onnection to create the conference, or asking the remaining bridging 
users and/or p rimary user to disconnect so that the conference can be 
completed. At completion of the conference, the parties that left the call 
can reenter the call if control of the conference remains with the primary 
terminal. If control of the conference does not remain with the primary 
terminal, the bridging user must conference the primary terminal and the 
bridging user back into the call as required.
If the bridging user has no other available bridged appearances of the 
primary extension (other than the one he or she is currently on), the 
bridging user, after pressing the Conference/Transfer button, must select 
a call a p pearance to be used for the conference, before dialing the 
number.
nCoverage Answer Group
It is recommended that the primary (analog) terminal not be a memb er of 
a call coverage answer group, because calls to the primary terminal as a 
member of the group 
are not brid g ed.
If the primary terminal is made a member of a coverage group, coverage 
criteria is based entirely on the criteria of the primary terminal. This means 
that a call to the primary terminal that requires call coverage treatment 
follows the p ath of the primary terminal and not the path of any of the 
terminals with bridged appearances of the primary terminals. In this case, 
it would  be desirable to have the bridging user in the coverage p ath of the 
primary terminal. Then, when a call to the primary terminal requires 
coverage treatment, it follows the coverage path to the brid ging user’s 
terminal, call appearances of the call are d rop ped, and the call terminates 
at the bridging user’s terminal as a coverage call.
nData Privacy
Data Restriction
When Data Privacy is activated or Data Restriction is assigned to a station 
involved in a b rid ged call and the primary terminal and/or brid ging user 
attempts to bridge onto the call, Data Privacy and Data Restriction are 
automatically overridden (or deactivated in the case of Data Privacy).

Issue  3   March 1996
3-303
nPriority Calling
Call Priority Calling apply only to an active call on the primary terminal 
which has no one else bridged on. If one or more bridging users are active 
on a call, Priority Calling calls are denied whether or not the primary user 
is also off-hook on the call. A bridging user cannot bridge onto a call with 
the primary user if there is also a call waiting.
nPrivacy-Manual Exclusion
Privacy-Manual Exclusion can only be activated b y a bridging user (a 
button is required for Privacy-Manual Exclusion). Activation of 
Privacy-Manual Exclusion prohibits any further bridging onto the call. If a 
bridging user activates Privacy-Manual Exclusion while the primary 
terminal and/or other bridging users are active on the call, the primary 
terminal and all brid g ing users except the activator are dropped from the 
call.
nHold—Automatic
A call cannot be put on hold if more than one user is active on that call.
The primary terminal user, when no other bridges are active on the call, 
can put the call on hold, using normal single-line hold procedures. If the 
primary terminal user successfully soft holds the c all, the status lamp at all 
of the bridged appearances shows the hold indication; and then the call 
can be put on hard hold by dialing the hard  hold FAC. The hard held call 
is no longer accessible to the bridging users until it is taken off hold by the 
primary terminal user. After the call is p ut on hard hold, any new call to the 
primary terminal is tracked by the bridged appearances.
A bridging user can place an active call on hold (if the primary terminal or 
any other bridges are not active on the call) by using normal 
multi-appearance hold procedures. Any attempt to enter the held call 
returns it to the status of an active call that can then be accessed using 
bridging procedures.
If hold is not allowed because of the preceding reasons, the user can just 
go on-hook and then reenter the call as required, because the call 
remains accessible as long as the p rimary terminal or any bridging user is 
active on it.
nHot Line Service
If a single-line voice terminal is administered for Hot Line Service, brid ged 
appearances of that voice terminal’s extension also places a hot line call 
automatically when a user g oes off-hook on that bridged appearance.
nHunt Group (DDC or UCD)
Brid ged call appearances cannot be used in conjunction with DDC or 
UCD hunt groups.
Although a bridged extension can be assigned to a hunt group, such 
assignment is not recommended because DDC/UCD calls do not 
terminate at any bridged appearances of that extension on other stations. 
						

							Feature Descriptions
3-304Issue  3   March 1996 
nInternal Automatic Answer (IAA)
Calls terminating to a bridged appearance of an IAA-eligible station are 
not eligible for IAA.
nLast Number Dialed
Activation of the Last Numb er Dialed feature causes the last numb er 
dialed from the activating voice terminal to be redialed, regardless of the 
extension number used (primary or bridged call appearance).
nLeave Word Calling (LWC) 
A LWC message left by a user on a bridged call appearance leaves a 
message for the called party to call the primary terminal extension number 
(that is, the feature is 
EXTENSION-BASED).
When a user calls a primary terminal, and activates LWC, the message is 
left for the primary terminal, even if the call was answered at a bridged call 
appearance.
LWC messages left by the primary terminal user can be canceled by a 
bridged appearance user (for example, the secretary can cancel a LWC 
message left by the b oss).
nPersonal Central Office Line (PCOL) 
A single-line primary terminal cannot be a memb er of a PCOL group.
nPreference
Ringing Line Preference selects an alerting b rid ged appearance; Idle Line 
Preference does not.
nPriority Calling
The primary terminal user or the bridging user can make a priority call. If a 
priority call is made to an idle primary terminal, the primary terminal and all 
bridging users are alerted by priority alerting.
For information on termination of a priority call to an active primary 
terminal, see Call Waiting Termination/Priority Calling.
nRinger Cutoff
Ringer Cutoff requires a button; therefore, it cannot b e activated b y the 
primary terminal user. Bridging user activation of Ringer Cutoff has no 
impact on the primary terminal or the other bridging users. However, it 
prevents the bridged user’s station from ringing on a non-priority call 
whether the call is to the user’s primary extension or a brid ged 
appearance. This a 
TERMINAL-BASED feature.
nRingback Queuing
Ringback Queuing is not provided on calls originate d from a bridged call 
appearance. Ringback Queuing is automatically invoked for a primary 
terminal (primary terminal), and the resulting Callback call alerts at  
						

							Brid ged Call Ap pearance— Single-Line Voice Terminal
Issue  3   March 1996
3-305
bridged appearances as well as at the principal user’s station. That call 
can be answered from the primary user’s station or from any bridged 
appearance.
nService Observing
The primary terminal user or bridging user can bridge onto a Service 
O bserved call at any time. If the primary terminal is being Service 
Observed and an incoming call is answered by the bridging user, the call 
is not observed unless or until the primary terminal user brid ges onto the 
call. Conversely, if the bridging user is being Service Observed and an 
incoming call is answered by the primary terminal user, the call is not 
observed unless or until the brid ging user bridges onto the call.
If the bridging user activates Service Observing, utilizing a bridged 
appearance, Service Observing is activated for the bridging user (that is, 
TER M I N A L - B A SE D feature).
nTerminating Extension Group (TEG) 
TEG calls cannot be answered or bridged onto from a bridged 
appearance of the TEG member’s primary extension.
nTransfer
A call cannot be transferred by an analog station if more than one user is 
active on that call.
The primary terminal user, when no other bridges are active on the call, 
can transfer the call using normal single-line transfer procedures. Any 
attempt by a b rid ging user to bridge onto this call during a successful 
transfer attempt is denied (a standard denial response is returned to the 
bridged appearance).
An analog brid ging user, alone on a bridged call, can transfer the call, 
using normal transfer procedures. Any attempt  by the primary terminal 
user to bridge onto this call during a successful transfer attempt is 
ignored; and any attempt to bridge on by a brid ging user is denied.
If the bridging user has no other available bridged appearances of the 
primary extension (other than the one he or she is currently on), the 
bridging user, after pressing the Conference/Transfer button, must select 
a call a p pearance to be used for the transfer, before dialing the number.
nVideophone 2500
A user may not use an analog bridge to a Videophone 2500 principal that 
is on a video call. 
						

							Feature Descriptions
3-306Issue  3   March 1996 
nVoice Message Retrieval
A voice message to the primary terminal can be retrieved on a bridged 
appearance by the bridging user. If a security code is required to retrieve 
the message, the bridging user must use the security code of the primary 
terminal.
nVoice Paging
The use of Voice Paging automatically invokes Privacy Manual-Exc lusion; 
therefore, interactions for this feature are the same as for Privacy-Manual 
Exclusion.
Administration
The Brid ged Call Ap pearance — Single-Line Voice Terminal feature is 
administered on a per voice terminal basis by the system manager. A primary 
single-line terminal must be translated before any brid ged a p pearances can be 
translated to point to it. Also, the bridged appearances of the primary terminal 
must be removed before the primary terminal can be removed.
See “ Bridg e d Call A ppearance — Single-Ap pearance Voice Terminal” in the 
DEFI NI TY Generic 3 Version 4 Implementation, 555-230-655, or DE FI NITY  
Communications System Generic 3 V2/V3 Implementation
, 555-230-653, for 
instructions.
Hardware and Software Requirements
No a d ditional hardware or software is required. A Call Coverage module can be 
used to provide up to 20 bridged call appearances.
