							Terminal Translation (with Security Measures)
Issue  3   March 1996
3-1145
nCall Coverage Answer Group
Members in a group cannot be disassociated while there is still an 
incoming call to the group. In this case all sets are seen as active and 
therefore cannot be disassociated.
If any endp oint previously administered without hardware translation is 
inserted into translation via TTI  or station administration, that endpoint is 
excluded from all transactions taking place in the call  coverage answer 
group.
nCall Forwarding
A station can disassociate while call forwarding is active. If a destination 
extension for call forwarding disassociates, call forward ing to that 
extension remains  active.
nCall Park
A terminal is not allowed to be disassociated while placed in a parked 
state by another set. It is virtually p ut on hold.
nCall Pickup
The primary extension of a call pickup group cannot disassociate while a 
call is attempting to terminate. All secondary memb ers are allowed to 
disassociate while a call is terminating to a primary extension. If a call has 
terminated to any extension within a group, any member of the group may 
disassociate. If a c all has or has not terminated, and a member of a group 
disassociates, that memb er does not join the  group for the call that is 
currently in progress, but is available for all subsequent calls to that 
group.
nConference
See “Hold” below.
nCustomer Provided Equipment (CPE ) Alarm
If a station that has been administered with a customer provided 
equipment alarm, enters the system  translation while an alarm is active, 
then the newly associated station receives the alarm indication  upon 
entering the system.
nHunt Group UCD/DDC
Any member of a hunt group that is not the target of the current call (not 
ringing), can disassociate itself. The primary (ringing) extension cannot.
If any endp oint previously administered without hardware translation is 
inserted into translation via TTI  or station administration, that endpoint is 
excluded from all transactions taking place in the hunt  group. This means 
that a member does not join the other memb ers of an incoming call for one 
that is taking place  during the ‘‘binding’’ of the station to the port location. 
The mem ber is a ble to join in all subsequent calls.

nHold
Neither party, the one that puts another on hold, nor the one that is being 
held can perform  disassociation.
nIncoming Destination
See the “station-to-Station Call” section.
nIntercom Group
See the “station-to-Station Call” section.
nMessage Light
All messages need not be delete d prior to disassociation. If a station 
should receive messages while it is in the untranslated state, when the 
terminal receives  hardware translation, the message light is updated.
nSend All Calls
Send all calls remains active when a station becomes disassociated.
nStation-to-station Call
No disassociation is performed until a call is established. No 
disassociation can occur while a set is ringing.
nTerminating Extension Group
Members in a group cannot be disassociated while there is an incoming 
call to the group. All members of the group are seen as active, since they 
are ringing and busy indicator lights are flashing.
If any endp oint p reviously administered without hardware translation via 
TTI or station a dministration,  that end point is excluded from all 
transactions taking place in the termination extension group. This means 
that a member does not join the other memb ers of an incoming c all for one 
that is taking place  during the binding of the station to the port location. 
The mem ber is a ble to join in all subsequent calls to the group.
nTransfer
After a connection has been established from the first to the third party, 
the second party, the one who  performed the transfer, can be 
disassociated. Parties one and three are treated as a station-to-station 
call.
nAttendant
Because the attendant is a central focus for incoming calls, it is advisable 
to have the attendant in  Position Busy Mode, so as to route incoming calls 
away from the attendant attempting to disassociate. It is possible to have 
the attendant in Position Available Mode and still d isassociate. Any calls 
queued, held, or seen as active for the attendant, prevents disassociation.
nIncoming Destination 
						

							Terminal Translation (with Security Measures)
Issue  3   March 1996
3-1147
An incoming d estination is not allowed to be disassociated while a call is 
in progress to that extension,  regardless of whether the extension is a 
station or an attendant.
nAttendant Night Service
The night service station cannot be disassociated while in night service. 
For the removal of any endpoint a dministered without hardware translation 
while night service is  activated, see that particular section.
nAttendant Release Loop Operation
All calls held with the release loop operation by the attendant are 
reclassified as attendant g roup  calls if  the attendant disassociates before 
the attendant timed reminder interval expires.
nAttendant to Attendant
To remove an attendant see the station-to-station section.
nNight Service-Trunk Group
If the night service destination is a station, disassociation operates the 
same way as disassociation for  stations.
Administration
The following provides information on the administration of TTI.
TTI Port Assignment
A TTI Port may be assigned to other resources through the appropriate 
administration screen, just as if the p ort was unadministered. A TTI Port address 
may be assigned to an extension on the “ Station”  form, for examp le.
Terminal Moves and Site Data
TTI can be used for implementing station moves. That is, the user disassociates 
the station from its port with TTI, unplugs the station from the jack, plugs the 
station in a another jack in a different location, and associates the station to its 
new port location with TTI. Certain translations is associated with the port and 
other translations is associated with the extension during a TTI station move. 
						

							Feature Descriptions
3-1148Issue  3   March 1996 
Table 3-85 lists these associations.
The ability to automatically move appropriate translation with the station is 
needed to prevent time-consuming manual translation changes.
Administration without Hardware
If a fully translated station, attendant, or data module is removed via 
administration, or if it is disassociated from its port by putting an
 X in the “Port”  
field on the ‘Station’ or ‘Data Module’ screen, the port becomes a Voice or Data 
TTI Port if TTI is set to 
voice or data in the system. If TTI is off in the system, then 
a port d isassociated from its station or d ata module becomes an unadministered 
port.
Enabling/Disabling TTI
The following is information regarding the enabling and disabling of TTI.
System Parameters Customer Option Screen
A “TTI” field on the “ System Parameters Customer-O ption” screen gives Services 
Personnel the option to turn on the TTI feature for a customer. A 
y (yes) after this 
field denotes that TTI is available; a 
n (no) d enotes that TTI is not available on the 
switch.
System Parameters Features Screen
If TTI is allowed on the switch via the customer option screen, a field on the 
‘System Parameters Features’ screen is used to enable or disable TTI on a 
system wide basis.
System Parameter Operation
The “ TTI System Parameter”  field may have one of five values:
Table 3-85. Site Data Association
Port Extension
Building Color
Floor Speakerphone
Room Headset
Jack number Cord  length
Cable Mounting

nTTI Voice — TTI is turned on, the default translation generated for a TTI 
Port is for a voice or voice/data terminal, and the activation/deactivation 
sequence comes from a station keypad.
nTTI Data — TTI is turned on, and the d efault translation generated for a TTI 
Port is for a stand alone data module. The activation/ deactivation 
sequence comes from a data terminal.
nOff — TTI is turned off for the system.
nSuspended — TTI was previously on for TTI Voice or TTI Data but TTI port 
translation generation is temp orarily prevented. Existing TTI port 
translations are not removed but no further translations are allowed 
(including via board insertions) until this flag is manually set to TTI Voice or 
TTI Data or Resume.
nResume — When TTI is manually susp ended, the system administrator 
may set the “ TTI System Parameter”  field to Resume. The state of TTI is 
then set back to what it was before TTI was manually suspended.
When TTI is turned on for the system (the first two cases a bove), the following 
actions takes place:
nIf TTI was  previously turned  on  but in a  different state for example, a voice 
to d ata state or vice versa, the old TTI translations are removed and the 
new ones a d ded on a board by board basis.
nIf TTI is set to TTI Voice mode, then default TTI translations are g enerated 
for every unadministered port on all d igital, hybrid, and analog board s.
nIf TTI Data translations exist for a digital board when TTI is set to Voice, the 
TTI Data translations are removed  and TTI Voice translations are added in 
their place.
nIf TTI is set to TTI Data mode, then default TTI translations are generated 
for every unadministered port on all d igital and data line boards in the 
system.
nWhen TTI is set to Data, the TTI Voice translations are removed and TTI 
Data translations a d ded in their place.
nWhenever a new digital board is inserted when the system is in TTI Data 
mode, or when a digital, hybrid, or analog b oard is inserted when the 
system is in TTI Voice mode, the unadministered ports on the board 
becomes TTI ports.
nWhen TTI is turned off, all translation for the TTI ports are removed in the 
system; these ports return to an ‘‘unadministered’’ state.
TTI Status Form
This form checks on the status of TTI port translation generation after TTI has 
been turned on for the system. 
						

							Feature Descriptions
3-1150Issue  3   March 1996 
Save Translation Operation
All TTI port translations are saved if a ‘‘save translation’’ administration operation 
is requested. This lessens the impact to booting and board insertion by reading 
the translations from disk or tape instead of recreating them.
If a ‘‘save translation’’ operation is requested while the system is actively 
generating TTI port translations as a result of turning the TTI system parameter 
on, the TTI  port generation process is automatically suspended while the ‘‘save 
translation’’ operation executes. When the o peration finishes, the TTI port 
generation is automatically resumed.
Transaction Logging
When a set is associated or d isassociated through the use of TTI, the transaction 
appears in the system transaction log. This log can be displayed by the ‘‘list 
history’’ command on the administration console.
TTI Security Code
A single 1 to 7 d igit TTI security code is administrable on the ‘System Parameters 
Features’ sc reen. This c o de is entered during the TTI associate/disassociate 
sequence after the TTI associate/disassociate feature access code. It is not an 
optional field.
Feature Access Codes
The TTI Association and Disasso ciation Feature A c cess Codes must b e 
administered on the ‘Feature Access Cod e’ screen before any TTI transa ctions 
can occur.
Hardware/Software Requirements
None. 
						

							Terminating Extension  Group (TEG)
Issue  3   March 1996
3-1151
Terminating Extension Group (TEG)
Feature Availability
This feature is available with all Generic 3 releases.
Description
Allows an incoming call to ring (either audible or silent alerting) as many as four 
voice terminals at one time.  Any user in the group can answer the call.
Any voice terminal can be administered as a Terminating Extension Group (TEG) 
member; however, only a multiappearance voice terminal can be assigned a 
TEG button with associated status lamp.  The TEG button allows the user to 
select a TEG call appearance for answering or bridging onto an existing  call but 
not for call origination.
When an incoming call is answered by a TEG member, a Temporary Bridged 
Appearance is maintained at the multiappearance voice terminals in the group. 
However, the Temporary Bridged Ap pearance is not visible on a call 
appearance. Any of the TEG members can bridge onto the call by pressing the 
TEG button, if assigned.  For example, suppose an incoming call has been 
answered by a certain TEG member, and this TEG memb er does not have the 
needed information.  If another member has the needed information, that 
member needs only to bridge onto the call to provide the information.
The Privacy — Manual Exc lusion feature can be assigned to any or all of the 
multiappearance voice terminals in a TEG.  This allows the answering TEG 
mem ber, by pressing the Exclusion button, to prohibit bridging by other group 
members.  Pressing the button again reestablishes the bridging capability.
A single-line voice terminal administered as a TEG member is rung for a TEG call 
if it is idle.
A TEG is established by associating the individual member’s extension numb er 
with a TEG extension number.  The mem bers have call placing and receiving 
privileges for their individual extension numb ers, as d efined by the assigned 
COR. Each TEG is also assigned a COR.  The g roup COR overrides an individual 
member’s COR on calls to the g roup.  Thus, the mem bers could be Termination 
Restricted, but still receive TEG calls.
Considerations
TEGs are useful when it is desirable to have incoming calls to a specific 
extension number ring more than one voice terminal simultaneously.  For 
example, the appliance department of a large retailer might have three voice

3-1152Issue  3   March 1996 
terminals.  Anyone in the  department can answer the call.  The salesperson most 
qualified to handle the call can bridge onto the call from either of the other two 
voice terminals.
A voice terminal user can b e a member of more than one TEG, b ut can have only 
one TEG button for each group.
A TEG can only handle one TEG call at a time. If any member of a TEG is active 
on a call to the TEG, a second call to the TEG waits until the first call is terminated 
before it rings the TEG. The TEG members have no way to know when a TEG c all 
is waiting. If a coverage path is assigned to the TEG, the waiting call routes 
accordingly.
Interactions
The following features interact with the TEG feature.
nAutomatic Callback
This feature cannot be activated for a TEG.
nBrid ged Call Ap pearance
Calls to a TEG cannot be bridged, except via a Temporary Bridged 
Appearance.
nCall Coverage
Calls to a TEG can be redirected to alternate answering positions 
whenever the Call Coverage feature is assigned and no group member is 
available to answer the call. If any member of a TEG is active on a TEG 
call, all subsequent TEG calls redirect to coverage. However, a TEG 
cannot serve as an alternate answering position.  In other words, a TEG 
can have a Call Coverage path assigned, but cannot b e a p oint in a Call 
Coverage path.
A Send Term button for the TEG can be assigned to any or all group 
members who have multiappearance voice terminals.  When the Send 
Term button is pressed, all calls to that TEG redirect to coverage.  The 
associated status lamp lights on the activating voice terminal and all other 
voice terminals with a Send Term b utton. Any memb er with a Send Term 
button can deactivate Send Term by pressing the button.  The Send Term 
status lamp then goes dark on all voice terminals.  Incoming calls are 
again directed to the group.
nCall Park
A TEG call cannot be parked on the group extension number; however, a 
group member answering a call can park such a call on his or her own 
extension number.
nDDC and UCD
A TEG cannot be a member of a DDC or UCD group.

Issue  3   March 1996
3-1153
nInternal Automatic Answer (IAA)
Calls to a Terminating Extension  Group extension are not elig i ble for IAA; 
however, calls placed to the individual extension are eligible.
nLW C  
LWC messages can be stored for a TEG and can be retrieved by a 
member of the group, a covering user of the group, or a systemwide 
message retriever.  The Voice Terminal Display feature and proper 
authorization can be assigned to the message retriever. Also, a remote 
Automatic Message Waiting lamp can be assigned to a group member to 
provide a visual indication that a message has been stored for the group.  
One indicator is allowed per TEG.
nTemporary Bridged Appearance
At multiappearance voice terminals in the TEG, a Temp orary Brid ged 
Appearance is maintained after a call is answered.  This allows other 
members of the group to bridge onto the call.
The Privacy — Manual Exc lusion feature, when activated, prevents other TEG 
members from bridging onto a call.  A TEG member who attempts to bridge onto 
a call with Privacy — Manual Exclusion activated is dropped.
Administration
TEGs are administered by the System Manager.  The following items require 
administration for each group:
nGroup number
nExtension number for the group
nGroup name (for display purposes)
nCall Coverage path number
nGroup COR
nUp to four group member extension numbers
The following items can be administered to multiappearance voice terminal TEG 
members:
nTEG button with associated status lamp.
nExclusion button associated with the TEG extension number. (Keeps other 
group members from bridging onto an existing call.)
nSend Term b utton for the TEG extension number.
nRemote Automatic Message Waiting lamp (one per TEG extension 
number).
nAudible or silent alerting.
