							Brid ged Call Ap pearance— Multi-Ap pearance Voice 
Terminal
Issue  3   March 1996
3-287
This leaves the other two-lamp buttons as call a p pearances, or with other 
features such as CAS.
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.
For G3V2 and  later releases, a conference tone can be administered. If the 
conference tone is enabled, a conference tone is heard when two parties are 
bridged together on an active call with a third party.
Interactions
The following features interact with the Bridged Call Ap pearance—
Multi-Appearance Voice Terminal feature.
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. This is true even when the 
voice terminal has no appearances of its primary extension.
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).
The display at a p rincipal will show the same information for a brid g ed call 
appearance as it would for a non-bridged call. For calls to the principal’s 
extension number, the display at a zero call ap p earance bridging station 
shows a call from the originator to the principal with no “redirection 
reason” character. As stations bridge onto the call, the display updates to 
show the numb er of parties in the conference.
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 station, 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 station. Displays at all (principal and bridged 
users) stations show that it is a Callback call.

Terminal
Issue  3   March 1996
3-289
nAutomatic Call Distribution (ACD)
ACD directs calls only to the primary extension, not to bridged 
appearances of the primary extension. Furthermore, if a bridged 
appearance is active, the primary is considered active and no calls are 
directed to the  primary from the ACD group (unless a dministered for 
Multiple Call Handling).
nIntercom—Automatic and Intercom—Dial
Brid ged appearances of a primary extension number are not rung  for 
intercom calls. Furthermore, if a station has no p rimary call appearances it 
can never be rung for an intercom call. Therefore, if a secretary is 
screening all calls for the principal, and is indicating who is calling via 
intercom, the principal must have a call a p pearance on which to receive 
and send intercom calls.
nCall Coverage
Coverage criteria for brid ged call appearances is based entirely on the 
criteria of the primary extension associated with bridged appearance. 
That is, a call to the primary extension that requires call coverage 
treatment follows the coverage path of the primary extension and not the 
path of any of the bridged appearances. Bridged call ap pearances d o not 
receive redirection notification.
A user with bridged call appearances can activate or deactivate Send All 
Calls for a principal’s primary call appearance.
It is recommended that the primary terminal not b e a member of a call 
coverage group,  because calls to the primary terminal as a memb er of the 
group are not bridged.
With G3V4 and later releases, the system can be administered so that a 
call can appear at a terminal as both a bridged call and a redirected call. 
In this way, if the bridged user is the first coverage p oint the call will 
redirect to that terminal when the coverage criteria are met.
With G3V3 and earlier releases, if the principal is an analog voice terminal 
with a brid ged call appearance on a multi-appearance voice terminal, an 
incoming call to the analog voice terminal that  goes to coverage will 
terminate at a primary call appearance on the bridging user’s voice 
terminal as a coverage call. the call is dropped from the analog voice 
terminal and the bridged call appearance on the bridging user’s voice 
terminal. In G3V4, if the bridging user is a zero primary call appearance 
voice terminal, the c all cannot redirect to the bridging user since there are 
no primary call appearances. Therefore, the call will redirect to the next 
available coverage point.
nCall Detail Recording (CDR)
If a bridging user originates and/or answers a call on a bridged 
appearance, the extension of the bridge is recorded as the calling/called 
terminal. A conference or transfer by a bridging user also a ppears as 
though it was performed by the terminal user. 
						

							Feature Descriptions
3-290Issue  3   March 1996 
When a call originated from a bridged call appearance on a terminal 
administered for zero primary call a ppearance is recorded by CDR, the 
extension number associated with the appearance is recorded as the 
calling party. A conference or transfer by a bridged call appearance on a 
zero primary call appearances terminal also appears as though it were 
performed by the extension associated with the appearance.
nCall Forwarding All Calls
Call Forward Busy/Don’t Answer
Call Forwarding c an be activated or canceled for the primary extension 
number from any bridged call appearance of that number; when 
activated, calls to the primary extension number do not terminate at the 
bridged call a p pearances, 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 forwarde d unless 
Ringing — Ab breviated and Delayed is administered.
nCall Park
When a call is parked from a bridged call appearance, it is parked on the 
primary extension number associated with the bridged appearance.
nCall Pickup
If a voice terminal receives ringing on a bridged call appearance, the 
incoming call can be picked up by members of that voice terminal’s Call 
Pickup group. This causes all bridged call a p pearances to be dropped. 
Calls ringing at a primary terminal can be picked up by members of the 
terminal’s Call Pickup group. However, if the primary terminal and the 
bridging user’s primary terminal are not in the same Call Pickup group, 
then the bridging user cannot pick up calls to other memb ers 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 to terminate on the brid ging user’s primary extension 
button, and the primary terminal and all bridged appearances of the call 
are dropped.
If the bridging user has appearances of numerous terminals (for example, 
Sales, Service, Warehouse, and so on), and it is not desired that the calls 
be answered b y anyone other than the terminal user or the bridging users, 
then the bridging user(s) should not be assigned to a pick up group.
A terminal with zero primary call appearances can be assigned to a Call 
Pickup group.
nClass of Restriction (COR) 
The COR assigned to a voice terminal’s primary extension also a p plies to 
calls originated from a bridged call appearance.

Terminal

nConference—Attendant
Conference
—Terminal
Conferences can be set up on brid ged appearances using the usual 
conference operations. Either a primary extension button or a brid ged 
appearance button can be used to make the calls for a d ding to the 
conference. With G3V3 and earlier releases, if the bridging user has at 
least one available bridged appearance of the primary extension (other 
than the one he or she is currently on), the system automatically selects a 
bridged call a p pearance for the conference when the 
Conference/Transfer button is pressed. 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 brid g ing user, after pressing the 
Conference/Transfer button, must select a call appearance (or the users’ 
own primary extension) or a bridged appearance of some other extension 
to be used for the conference, before dialing the number.
With G3V4 and later releases, the system can be administered to 
automatically select the first idle appearance if there is no idle 
appearance with an extension matching the extension that is conferencing 
the call.
NOTE:
When the user d epresses the Conference button (the second time) 
to connect the parties together, the newly formed conference call 
appears on the primary or brid ged a p pearance to which the user 
was connected at the time of that last Conference button 
depression. The other a p pearance is disassociated from the 
Conference call.  Thus, if the original call was on a bridged 
appearance, and the conference is formed on an appearance of the 
bridged user’s own primary extension, the bridged extension 
becomes d isassociated from the conference call and the principal 
user of that bridged extension can no longer bridge onto the 
conference.
This d isassociation of the conference from the brid g ed extension 
can be avoid e d by setting up the conference in the o p posite ord er. 
To do so the user first uses the Hold button to hold the original call 
on the bridged appearance, then selects a call appearance and 
calls the party to be added, then d epresses the Conference (or 
Transfer) button, then selects the held bridged appearance, then 
depresses the Conference button (again).  When this procedure is 
used, the conference is formed on the bridged ap pearance so the 
primary user of the bridged extension can still brid ge onto the 
conference call.
NOTE:
If the primary user and the brid ged user are both on the call when 
one user transfers the call, the user performing the transfer becomes 
the controlling user for the participation of both users on the  
						

							Feature Descriptions
3-292Issue  3   March 1996 
conference. To disassociate the appearance from the call, the 
controlling user must be the latter of the two users to hang up from 
the call. If the controlling user hangs up first, the appearance goes 
on soft hold when the non-controlling party hangs up. In this case, 
one of two things must occur to disassociate the appearance from 
the c all: (1) all other p arties on the call hang up, or (2) the controlling 
user rejoins the call and hangs up again.
The display shows the number of other active parties in a call, including 
active bridged appearances.
nConsult
Brid ged call appearances of the primary extension do not ring on a 
consult call to the primary extension.
nCoverage Answer Group (CAG)
Brid ged call appearances of a p rimary extension d o not ring when there is 
a CAG call to the primary. Brid g ed call appearances cannot bridge onto 
the 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.
G3V4 and later releases provide a system option that prohibits brid ged 
terminals from bridging on to a call when the c all has Data Privacy or Data 
Restriction enabled.
nFacility Busy Indication
With G3V3 a n d earlier releases, when the user presses the busy-ind 
button, a call is placed to the resource from an idle primary call 
appearance. With G3V4 a n d later releases, for zero primary call 
appearance voice terminals, the call is placed to the resource from the 
first available bridged call appearance.
nHold—Automatic
Any user (primary or bridged appearance) can place an active call on 
hold. If only one user is active on a call and places that call on hold, then 
the indicator lamp at both the principal’s appearance button and the 
bridged party’s a p pearance button shows that the call is on hold. If more 
than one user is bridged onto the active call, and one of the users 
activates Hold, the activator receives ‘‘hold’’ indication for the call and 
status lamp of all other bridged users remain ‘‘active.’’
nHunt Group (DDC or UCD)
Brid ged call appearances cannot be used in conjunction with DDC or 
UCD hunt groups. 
						

							Brid ged Call Ap pearance— Multi-Ap pearance Voice 
Terminal
Issue  3   March 1996
3-293
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.
If a member of a UCD group is off-hook on a bridged appearance, and 
that user’s primary extension numb er (which is in the UCD group) is idle, 
then a UCD call will not terminate on that user’s p rimary extension number 
unless it is administered for Multiple Call Handling.
nIntercom—Automatic
Automatic and/or intercom calls to the primary extension d o not ring at the 
associated bridged appearances.
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 voice terminal to be redialed, regardless of whether its 
own call appearance or a bridged call a p pearance is used.
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 extension number 
assigned to the bridged call appearance.
When a user c alls a p rimary extension, and activates LWC, the message is 
left for the primary extension, even if the call was answered at a bridged 
call appearance.
LWC messages left by the primary user can be canceled by a bridged 
appearance user (for example, a secretary can cancel a LWC message 
left by a boss).
nPersonal Central Office Line (PCOL) 
If a user is active on his or her primary extension number on a PCOL call, 
bridged call a p pearances of that extension numb er cannot be used to 
bridge onto the call. The call can only be bridged onto if another voice 
terminal is a member of the same PCOL group and has a PCOL button.
nPriority Calling
The primary terminal user or the bridging user can make a priority call. If a 
priority call is made to an idle terminal, the primary terminal and all 
bridging users are alerted by priority alerting.
nPrivacy-Manual Exclusion
Exclusion prevents any other user from bridging onto the c all. Activation of 
exclusion by any user (primary or bridged appearance) prior to placing a 
call, prevents any other user from bridging onto the call. Activation of 
exclusion by any user active on a call, while the primary user and/or any  
						

							Feature Descriptions
3-294Issue  3   March 1996 
other bridging users are active on the call, drops all other users from the 
call (including the primary user), leaving only the activator and the 
calling/called party on the call.
nRedirection Notification
Redirection Notification is not provided at stations with a brid ged 
appearance of a primary extension number unless Ringin g — 
Abbreviated and Delayed is administered to give notification.
nRingback Queuing
Ringback Queuing is not provided on calls originate d from a bridged call 
appearance. However, after the principal user of the bridged extension 
has activated ringback queueing, the resulting Callback call alerts at 
bridged appearances as well as at the principal user’s station.  The call 
can be answered from the primary user’s station or from any bridged 
appearance.
nRinger Cutoff
When activated at a multi-a p pearance station, Ringer Cutoff prevents any 
nonpriority (or non-intercom) incoming call from ringing at that station. This 
is independent of whether the c all is to the station’s primary extension or to 
any of the bridged appearances’ extension(s).
nService Observing
The terminal user or bridging user can brid ge onto a Service O bserved 
call at any time. If the terminal is being Service Observed and an incoming 
call is answered by the bridging user, the call is not observed unless or 
until the terminal user bridges onto the call. Conversely, if the bridging 
user is b eing Service Observed and an incoming call is answered by the 
terminal user, the call is not observed unless or until the bridging user 
bridges onto the call.
If the bridging user activates Service Observing, using a bridged 
appearance, Service Observing is activated for the bridging user.
nTerminating Extension Group (TEG)
TEG c alls to the primary extension do not ring at the associated bridged 
appearances. TEG calls cannot be answered or bridged onto from a 
bridged appearance of the TEG Member’s p rimary extension. The primary 
terminal should not be assigned to a TEG.
nTransfer
With G3V3 and earlier releases, 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 appearance to be used for 
the transfer, before dialing the number. 
						

							Brid ged Call Ap pearance— Multi-Ap pearance Voice 
Terminal
Issue  3   March 1996
3-295
If the bridging user has at least one available brid ged appearance of the 
primary extension (other than the one he or she is currently on), the 
system automatically selects a bridged call appearance for the transfer 
when the Conference/Transfer button is pressed.
With G3V4 and later releases, the system can be administered to 
automatically select the first idle appearance if there is no idle 
appearance with an extension matching the extension that is transferring 
the call.
NOTE:
If the primary user and the brid ged user are both on the call when 
one user transfers the call, the user performing the transfer becomes 
the controlling user for the participation of both users on the 
conference. The controlling user is immediately dropped from the 
call. When the non-controlling user hangs up, the appearance goes 
on soft hold. In this case, one of two things must occur to 
disassociate the appearance from the call: (1) all other p arties on the 
call hang  up, or (2) the controlling user rejoins the call and hangs up 
a gain.
nVoice Message Retrieval
A voice message to the primary extension can be retrieved on a bridged 
appearance by the bridged appearance user. If a security code is 
required to retrieve the messa ge, the bridging user must use the security 
code of the primary terminal.
nVoice Paging
The use of Voice Paging automatically invokes exclusion; therefore, 
interactions for this feature is the same as for Privacy-Manual Exc lusion.
Administration
The Brid ged Call Ap pearance — Multi-Ap pearance Voice Terminal feature is 
administered on a per-voice terminal b asis b y the System Manager. See 
“Bridged Call Ap pearance — Multi-Ap pearance Voice Terminal” in

Bridged Call Appearance—
Single-Line Voice Terminal
Feature Availability
Brid g ed Call Ap pearance—Single-Line Voice Terminal is available with all 
Generic 3 releases. Other bridging enhancements available only with G3V4 a n d 
later releases are identified throughout this feature description.
Description
Allows a multi-appearance terminal to have an appearance of a primary 
terminal‘s extension number. The appearance of the primary terminal’s extension 
number at a multi-appearance terminal is called a bridged call appearance.
G3V4 and later releases also allow an analog voice terminal to have a single 
bridged appearance of a multi-appearance voice terminal primary call 
appearance.
The b rid ged call a p pearance can be used to originate, answer, or bridge onto an 
existing call to or from the primary terminal user’s extension number.
The multi-appearance terminal user can use the bridged call appearance by 
lifting the handset and pressing the bridged appearance button or by pressing 
the bridged ap pearance button and lifting the handset. The user is then bridged 
onto the primary terminal’s extension numb er and can handle calls on that 
extension number.
The bridged single-line voice terminal user brid ges onto a call by going off-hook.
When the p rimary terminal is a single-line voice terminal, the user can also bridge 
onto an existing call originated, answered, or bridged onto b y the associated 
multi-ap pearance terminal(s) by just going off-hook.
An incoming call alerts at the primary terminal, and at all voice terminals that 
have a bridged call appearance of the primary terminal’s extension number. 
Each multi-appearance bridging voice terminal has visual alerting with the o ption 
of audible ringing for the bridged appearance of the primary terminal.
When the primary terminal user answers the call, the audible ringing stops at the 
primary terminal and at all the bridging user’s terminals, and the status lamps at 
all the multi-appearance bridged appearance buttons light steadily. The call can 
then be bridged onto by any of the brid ging users.
When a bridging user answers the call, the audible ringing stops at the primary 
terminal and at all of the brid g ing user’s terminals, and the status lamp s at all of 
the multi-appearance bridged appearance buttons light steadily. The call can
