Conference — Attendant
Feature Availability
This feature is available with all Generic 3 releases.
Description
Allows the attendant to set u p a conference call for as many as six conferees, 
including the attendant.  Conferees from inside and outside the system can be 
added to a conference call. To set u p a conference, the attendant dials a number 
and uses the split key to a d d each party to the rest of the conference.
Considerations
Whenever an attendant needs to talk with more than one p arty at the same time, 
the Attendant Conference feature can be used.  An attendant can also establish 
a conference call for other voice terminal users or parties outside the system.
The attendant can set up  only one conference call at a time.  The attendant can 
hold a conference call on the console or release from it.
The attendant cannot handle any other calls while setting up a conference call.
Once an attendant adds a party to a conference call (whether the call was 
established by an attendant or other voice terminal user), only the attendant can 
a d d another party to the call.
Interactions
The following features interact with the Conference — Attendant feature.
nBrid ged Call Ap pearance
A Bridged Ap pearance button can be used to make conference calls.
nCall Vectoring 
A call to a VDN can be included as a party in a conference call only after 
vector processing terminates for that call (for exam ple, after a successful 
route to command).
nTrunk-to-Trunk Transfer
If Trunk-to-Trunk  Transfer  is disabled and the attendant releases from a 
conference call involving only trunk conferees, the trunks are also 
disconnected.

nWhen a multi-function station (BRI/Digital/Hybrid) dials sufficient digits to 
route a call, b ut could route differently if a d ditional digits were dialed, the 
station will not recognize the Conference or Transfer buttons. The user 
must delay dialing for ten seconds or dial a # to indicate the call can be 
routed based on the digits already dialed. The Conference or Transfer 
buttons are then recognized and the o peration is c ompleted by the switch.
nAttendant Conferencing may not operate properly if the CO d oes not 
provide answer supervision and the “Answer Supervision Timeout” field is 
set to “0” and the “Receive Answer Supervision” is set to “y.”  In this case, 
the use of any non-zero number can be used to represent the number of 
seconds of delay required for answer supervision. 
If the CO 
does provide answer supervision, the “Answer Supervision 
Timeout” can be set to “0” and the “Re ceive Answer Supervision” can be 
set to “y.” 
Administration
For G3i-Global, G3rV1, G3V2, and later releases the administrator may specify 
on the System Parameters form lower limits on the numb er of parties that can be 
on a conference call. 
Hardware and Software Requirements
No a d ditional hardware or software is required.

Conference — Terminal
Feature Availability
Conference — Terminal is available with all Generic 3 releases.
Description
Allows multi-appearance voice terminal users to set up six-p arty conference calls 
without attendant assistance. 
Considerations
With the Conference — Terminal  feature,  voice terminal users can set up their 
own conference calls without assistance from an attendant.
With assistance from other users, a single-line voice terminal c an have more than 
three parties on a conference call. For example, one user can add a party, who 
can add another party, etc.
If a voice terminal user releases from a conference call involving only trunk 
conferees, the trunks are also disconnected if trunk-to-trunk connections are 
disallowed through administration.
Single-line voice terminal users can set u p three-party conference calls without 
attendant assistance, only if the “Allow Conference via Flash” field is set to y 
(yes) on the “Feature Related System Parameters” form.
Up to six parties may be conferenced together on an active call. If the 
conference tone feature is turned on, all six conferees hears the conference tone.
If an analog single line set has the Call Wait feature enabled and has created a 
conference call, the Call Wait feature is denied. For example, when caller A on an 
analog set is talking to caller B, then flashes and is talking to caller C, and flashes 
to conference B and C, then, if caller D calls caller A, the Call Wait feature is 
denied.
Interactions
nBrid ged Call Ap pearance
A Bridged Ap pearance button can be used to make conference calls.
nCall Vectorin g
A call to a VDN can be included as a party in a conference call only after 
vector processing terminates for that call (for exam ple, after a successful 
route to command).

nClass of Restriction (COR)
The COR of the party being added is always checked against the COR of 
the party controlling the add-on, but the new party’s COR is not checked 
against any other conferee’s CORs if Restriction Override is set to ‘‘all.’’  It 
is checked against ‘‘attendants’’ or ‘‘none.’’
nInternal Automatic Answer (IAA)
Internal conference calls are eligible to be automatically answered via the 
IAA feature. If more than one conference party has joined a conference 
call through automatic answer, such parties remain connected until either 
they or the controlling party drops the call.
nWhen a multi-function station (BRI/Digital/Hybrid) dials sufficient digits to 
route a call, b ut could route differently if a d ditional digits were dialed, the 
station will not re co gnize the Conference or Transfer buttons. The user 
must delay dialing for ten seconds or dial a # to indicate the call can be 
routed based on the digits already dialed. The Conference or Transfer 
buttons are then re cognized and the operation is c ompleted by the switch.
Administration
On the ‘System Parameters form there is a field where the administrator may 
specify lower limits on the number of parties that can be on a conference call. A 
conference tone is available through administration.
Hardware and Software Requirements
No a d ditional hardware or software is required.

Constellation Voice/Data Terminal 
Support
Feature Availability
This feature is available with the Generic 3 Version 3 and later release.
Description
Provides support for integrating voice terminals with the Constellation Voice/Data 
Terminal. The Constellation is a voice/data workstation that provides an 
integrated environment for applications using DCP-based (digital 
communications protocol) signaling.
The Constellation o perates in conjunction with an adjunct voice terminal.
Feature History and Development
The Constellation was available on the DEFINITY system Generic 2 and on a 
custom version of G3i. It is supported in its entirety in Generic 3 V3 and later 
releases. The Constellation terminal and its associated Cluster Controller are no 
longer manufactured or sold by AT&T. These are Memorex/Telex products that 
are natively supported on the DEFINITY  system Generic 3 V3 and later releases. 
Further details on Constellation terminal applications and installation should be 
obtained from Memorex/Telex.
Applications and Benefits
The Constellation Voice/Data Terminal provides enhanced capability for a 
telemarketing environment. It is meant to assist a telemarketing environment by 
interacting with the switch and a host comp uter to provide agents with 
information about the calling and called party. The  Constellation  interprets 
information a bout a c all, p asses the information to a host computer, and receives 
from the host information about the either party. The information sent b y the host 
computer appears on the workstation monitor in a user-supplied application and 
format.
The Constellation o perates by ‘‘listening’’ to the DCP connection b etween the 
switch and the voice terminal. When  a  new  call originates or terminates on the 
switch, the switch sends the Constellation a start-of-call message in the form of a 
DCP S-channel message (Transparent Call Control). This message contains the 
best available information about the calling party and called party. If either piece 
of information is not available, it sends a ‘‘NULL’’ message. Likewise, when the 
call has terminated, the switch sends a similar end-of-call message to the 
Constellation.

Considerations
G3V3 and later releases provide native support for the Constellation. ‘‘Native 
support’’ means the switch stores a predefined terminal type and fully supports 
the terminal operation. The constellation terminal is a Memorex/Telex product. 
Memorex/Telex is responsible for manufacturing and installing this terminal. 
automatically downloads the terminal typ e information to the terminal.
Administration
The Constellation is administered on the station form as a typ e ‘‘6538.’’ The form 
for this type includes a “Set” field, which requires one of the following values, 
based on the adjunct voice terminal:  ‘‘7401D,’’ ‘‘7406D,’’ ‘‘602A1,’’ ‘‘603A1,’’ or 
‘‘603D1.’’ The value in the “ Set”  field determines the remaining fields that ap pear 
on the form.
Hardware/Software Requirements
The Constellation requires the use of one of the following adjunct voice terminals:  
7401D, 7406D, 602A1, 603A1, and 603D1.
The adjunct voice terminal can function as a standalone station even when the 
Constellation is powered down.
The Constellation also requires a 6544 cluster controller to provide a data 
connection to the host. 
						

							Consult
Issue  3   March 1996
3-565
Consult
Feature Availability
Consult is available with all Generic 3 releases.
Description
Allows a covering user, after answering a coverage call, to call the principal 
(called party) for p rivate consultation.
Consult is activated by first pressing the Conference or Transfer button followed 
by the Consult button to call the principal. This places the calling party on hold 
and establishes a connection between the principal and the covering user. The 
covering user  can then add  the calling party to the conversation, transfer the call 
to the principal, or return to the calling party.
Details of how Consult is used in conjunction with Call Coverage are given in the 
Call Coverage feature description elsewhere in this section.
Considerations
Consult can be used to let a covering user consult with the principal, to 
determine whether he or she wishes to sp eak with the called party  (for example, 
an executive’s se cretary may wish to consult the executive on an established 
call).
Interactions
Consult calls use the Temporary Brid ged Appearance maintained on the call. At 
the conclusion of a Consult call, the bridged appearance is no longer 
maintained.
Brid ged Call Ap pearances of the principal’s extension are not alerted on a 
Consult call to the principal extension.
Consult is only used in conjunction with the Call Coverage feature.
A Consult c all acts as a p riority call and waits at a single-line voice terminal, even 
if the single-line voice terminal does not have Call Waiting Termination assigned.
Administration
Consult is administered by the System Manager on a per-voice terminal b asis. 
The only administration required is the assignment of a Consult button.
