nUniform Dial Plan
If a Uniform Dial Plan is in place between switches, tenant partition 
identification is not passed between the switches, and so tenant-partition 
restrictions are not enforced between the switches without special 
administration.
NOTE:
Tenant Partitioning restrictions do not override COR restrictions. 
COR restrictions are independent of tenant partitions.
Terminal Translation Initialization
Terminal Translation Initialization (TTI) allows you to merge an x-ported 
extension to a valid port by dialing a system-wide TTI security code and the 
extension from a telephone connected to that port. TTI also allows you to separate 
an extension from its port by dialing a similar separate digit sequence. This action 
causes the extension to be administered as an X port.
When TTI is enabled for voice, all voice ports (except Basic Rate Interface (BRI) 
ports) become TTI ports or ports from which a TTI merge sequence can occur.
TTI is usually used to move phones, however, it also supports connecting and 
moving attendants, data modules, voice/data telephones, and ISDN-BRI 
telephones.
Attendants
In order for attendants to use TTI, you must assign an extension to the attendant 
console. TTI port translations are the same for digital telephones and attendant 
consoles. To merge a digital TTI voice port and an attendant, you must first 
administer the attendant as an X port. Then a digital telephone must be plugged 
into the jack assigned to the attendant console, and the TTI merge digit sequence 
must be entered on the digital telephone. Once the TTI merge has been completed 
for the attendant console, the digital telephone must be unplugged and the 
attendant plugged into the jack.
An attendant console can be separated from its port only through administration. 
A TTI separate request from an attendant console gives the user intercept 
treatment.

Data modules
Data modules have different tones and digit sequences.
In the merge and separate control flow, different tones are given to the telephone 
user to give the current status of the TTI operation. Instead of audible tones, status 
messages are displayed on a telephone connected to a data module when 
activating the TTI sequence through keyboard dialing. If the TTI State field is set 
to 
data, you see the data display messages. If the TTI State field is set to voice, 
you hear the tones.
For a stand alone data module, the TTI merge/separate digit sequence is entered in 
one line at a dial prompt:
nDIAL: 
Separate prompts are not given for the TTI security code and extension.
Voice/data telephones
A telephone with a data terminal (DTDM) is treated as a telephone in the TTI 
merge and separation sequence. The DTDM is merged with and separated from its 
hardware translation at the same time the telephone is merged or separated. The 
TTI merge and separate sequence can only be initiated through the telephone for 
DTDMs; it cannot be initiated through the data port.
ISDN BRI telephones
The TTI separation sequence for Automatic-TEI SPID-initializing BRI telephones 
is identical to the sequence used for telephones. However, the merge sequence is 
different.
nSeparation sequence
1. Feature Access Code
2. Security Code
3. Extension 
nMerge sequence
1. Connect the telephone to any port to get power.
2. Program the SPID to the extension with which it will be merged.
3. Unplug the telephone (this is necessary even if the telephone is 
connected to its intended port).

4. Connect the telephone to its intended port (this port should indicate 
Equipment Type: TTI Port).
5. Receive dial tone.
— If there is dial tone, the merge is complete.
— If there is no dial tone, the telephone’s SPID is not an 
available extension.
You can dial the TTI merge sequence for BRI sets only if a user separates a BRI 
extension from its set and then wants to undo the process by reassociating the set 
to the same extension. Note that you cannot use the SAT to put an X in the port 
field of a BRI set that is still connected to the switch. You must use the TTI 
separation sequence from the set. 
Analog Queue Warning Ports and External Alert 
Ports
The analog queue warning port (used for hunt groups) and the external alert port 
may be administered with an X in the Port field. These extensions can be merged 
to an analog port via TTI. The merge must be done by an analog set, and then the 
analog set is unplugged from the port. These extensions cannot be separated from 
their port location with the TTI feature. A TTI separate request from one of these 
ports gives you intercept treatment.
Security measures
!SECURITY ALERT:
If you do not manage this feature carefully, its unauthorized use may cause 
you security problems. For example, someone who knows the TTI security 
code could disrupt normal business functions by separating telephones or 
data terminals. You can help protect against this action by frequently 
changing the TTI security code. You can further enhance system security by 
removing the Feature Access Code (FAC) from the system when it does not 
need to be used (for example, there are no moves going on at present). 
Consult the BCS Systems Security Handbook for additional steps to secure 
your system and find out about obtaining information regularly about 
security developments.
Interactions
n10-MET, 20-MET, 30-MET phones
You cannot use TTI to change 10-MET, 20-MET, or 30-MET phones.

nAttendant
 It is possible to have the attendant in Position Available Mode and still 
separate. Any calls queued, held, or seen as active for the attendant prevent 
separation.
nAttendant Night Service
The night service station cannot be separated while in night service.
nAttendant Release Loop Operation
If the attendant separates before the attendant-timed reminder-interval 
expires, all calls held with the release loop operation by the attendant are 
reclassified as attendant group calls.
nAutomatic Callback
If a telephone has Automatic Callback active for another telephone, 
executing TTI separate for either telephone breaks the automatic callback 
sequence.
nCall Coverage
If a telephone separates while Send All Calls or Goto Coverage is active, 
these features remain active while the telephone has no associated 
hardware. 
You can separate a telephone that is the target of Send All Calls or Goto 
Coverage; the features function as if the telephone were busy.
nCall Coverage Answer Group
If a extension was an X port, then rejoins the group as a result of a TTI 
merge, a PSA associate, or a port assignment, that telephone is excluded 
from all transactions already active in the call coverage answer group.
nCall Forwarding
A telephone can separate while Call Forwarding is active. If a destination 
extension for call forwarding separates, Call Forwarding to that extension 
remains active. Calls forwarded while the telephone is separated hear a 
busy signal.
nCall Pickup
If a line appearance is available, a member of a call pickup group may 
separate at any time. If a call is attempting to terminate, and a member of a 
group associates, that member does not join the group for the call that is 
currently in progress, but is available for all subsequent calls to that group.

nExpert Agent Selection
Station user records cannot be shared between TTI ports and EAS login ID 
extensions. This reduces the number of possible TTI ports your system 
provides, depending on the number of administered EAS login IDs. For 
example, if you administer 2,000 EAS login IDs, the maximum number of 
TTI ports that the system can provide is reduced by 2,000.
nHunt Group Uniform Call Distribution/Direct Department Calling
The system excludes telephones previously X-ported as a result of a TTI 
separate, a PSA dissociate, or administration from all transactions already 
active in the hunt group when the telephone is merged.
nSite Data
If Terminal Translation Initialization is enabled, a warning message 
displays when you tab off the Site Data fields.
If Terminal Translation Initialization is enabled, and you change the Port 
field on the Station screen from “x” to a real port number and change the 
Room, Jack, or Cable fields in the Site Data section, a warning message 
displays when you tab off the fields.
nTerminating Extension Group
If any member of the TEG (that was previously an X port as a result of TTI, 
PSA or telephone administration) is merged, that member is excluded from 
all transactions already taking place in the TEG when that member is 
merged. The member is able to join in all subsequent calls to the group.

Terminating Extension Group
A Terminating Extension Group (TEG) allows an incoming call to ring as many as 
4 phones at one time. Any user in the group can answer the call.

Detailed description
You can administer any phone as a TEG member; however, only a 
multiappearance phone can be assigned a TEG button with merged-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 a TEG members answers an incoming call, a temporary bridged appearance 
is maintained at the multiappearance phones in the group. However, this 
appearance is not visible. Any TEG members can bridge onto the call by pressing 
the TEG button.
Considerations
nA phone user can be a member of more than one TEG, but can have only 
one TEG button for each group.
nA TEG can handle only one TEG call at a time. Additional calls do not 
reach the TEG. If a coverage path is assigned to the TEG, the additional 
calls route accordingly.
Interactions
nAutomatic Callback
This feature cannot be active for a TEG.
nBridged Call Appearance
Calls to a TEG cannot be bridged, except via a Temporary Bridged 
Appearance.
nCall Coverage
A TEG can have a Call Coverage path assigned, but cannot be a point in a 
Call Coverage path.
A Send Term button for the TEG can be assigned to group members who 
have multiappearance phones. When a user presses Send Term, calls to the 
TEG redirect to coverage. The merged status lamp lights on all phones with 
a Send Term button. Any member with a Send Term button can deactivate 
Send Term by pressing the button. Incoming calls are directed to the group.
nCall Park
A TEG call cannot be parked on the group extension. However, a group 
member answering a call can park a TEG call on their own extension.
nDirect Department Calling and Uniform Call Distribution
A TEG cannot be a member of a DDC or UCD group.

nInternal Automatic Answer
TEG calls are not eligible for Internal Automatic Answer; however, calls 
placed to an individual extension are eligible.
nLeave Word Calling
Leave Word Calling 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 system-wide 
message retriever. Phone Display 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.
nPrivacy — Manual Exclusion
Privacy — Manual Exclusion can be assigned to any of the phones in a 
TEG to prohibit bridging by other group members. A TEG member who 
attempts to bridge onto a call with Privacy — Manual Exclusion active is 
dropped.
nTemporary Bridged Appearance
At multiappearance phones in the TEG, a temporary bridged appearance is 
maintained after a call is answered. Thus, other members of the group can 
bridge onto the call.

Time of Day Routing
You can use Time of Day Routing to select route patterns for calls according to the 
time of day and day of the week. You need to define the route pattern you want to 
use before you set up time of day routing.
You can route calls based on the least expensive route, and you can deny outgoing 
long-distance calls after business hours to help prevent toll fraud. You can use 
partition groups to assign different time of day route plans for different groups of 
users.

1554 Transfer 
20
Automatic Alternate Routing (AAR) or Automatic Route Selection (ARS) must 
be administered on your switch before you use Time of Day Routing. Time of Day 
Routing applies to all AAR or ARS outgoing calls and trunks used for call 
forwarding to external numbers.
Interactions
nDCS 
Be careful when you make Time of Day Routing assignments in a DCS 
environment. The user’s COR Time of Day Plan Number determines 
whether or not the call is routed to a DCS trunk group. The call loses 
feature transparency if it is not routed to a DCS trunk group.
When a call routes over a DCS trunk, the switch at the far end routes the 
call according to the COR Time of Day Plan Number of the incoming 
trunk.
nRemote Access
When remote access is used and an authorization code or barrier code is 
dialed for an AAR or ARS call, the COR Time of Day Plan Number of the 
barrier code or authorization code is used to route the call.

Transfer
Transfer allows telephone users to transfer trunk or internal calls to other 
telephones or trunks without attendant assistance.
Considerations
nYou can administer transferred-trunk calls to receive either music or silence 
if the first part of the transfer places the call on hold.
nMulti-appearance telephones must have an idle appearance to transfer a 
call.

nSingle-line telephone users momentarily flash the switchhook or press the 
RECALL button, dial the desired extension, and hang up. Multi-appearance 
telephone users press the 
TRANSFER button, dial the desired extension, and 
press the 
TRANSFER button again.
nIf, on the Feature-Related System Parameters screen, the Transfer Upon 
Hang-up field is 
y, users can transfer a call by pressing the TRANSFER 
button, dialing the desired extension, and then hanging up. The user can 
hang up while the desired extension is ringing or after the party has picked 
up. The user also can still press the 
TRANSFER button a second time to 
complete the transfer process.
nIf, on the Feature-Related System Parameters screen, the Abort Transfer 
field is 
y, users can abort the transfer a call by pressing the TRANSFER 
button, dialing the desired extension, and then hanging up or selecting any 
non-idle call appearance. The user must press the Transfer button again to 
complete the process (see Note). If the user selects an idle call appearance, 
the transfer still is active.
NOTE:
If both the Abort Transfer and Transfer Upon Hang-Up fields are y 
and you press the 
TRANSFER button and then dial the complete 
transfer-to number, hanging up the phone transfers the call.
nUsers of DCP, Hybrid, and wireless phones can transfer a call on hold 
without removing the call from hold. If there is only one call on hold, no 
active call appearances, and an available call appearance for the transfer, 
the user can transfer the call simply by pressing the Transfer button. 
DEFINITY ECS assumes the transfer is for the call on hold, and the 
transfer feature works as usual.
If there is more than one call on hold, the user must make a call active in 
order to transfer it. If the user presses the Transfer button with two or more 
calls on hold, DEFINITY ECS will ignore the transfer attempt since it will 
not know which call the user wants to transfer. If there are calls on hold and 
an active call, pressing the Transfer button will start the transfer process for 
the active call.
nDEFINITY ECS can be administered to display a confirmation message to 
users upon successful call transfers. The confirmation message will only be 
visible to users with DCP, Hybrid, wireless (except for 9601), or 
ISDN-BRI display phones. All of these phones, except for the Hybrids, can 
display the confirmation message in English, Spanish, French, Italian, or a 
language you define. Hybrid phones only display the message in English.
nYou can administer the system to return a transferred call to the originator 
if the transferred-to party does not answer within a set time limit. To do 
this, enter a value in the Station Call Transfer Recall Timer field on the 
Feature-Related System Parameters
 screen.

nAttendant Conference
This may not operate properly if the CO does not provide answer 
supervision. In that case, the Answer Supervision Timeout and Outgoing 
End of Dial fields (on the CO Trunk Group screen) must be set to the same 
non-zero number. The Receive Answer Supervision field must be set to 
n.
If the CO does provide answer supervision, the Answer Supervision 
Timeout and Outgoing End of Dial field must be set to 
0 and the Receive 
Answer Supervision field must be set to 
y. 
nBridged Call Appearance
A bridged call appearance can be used to transfer calls.
nCentreVu Agent
CentreVu Agent supports the conference and transfer of calls on hold, but it 
does not display the confirmation message for transferred calls.
nClass of Restriction
Set the Block Transfer Display field on the COR screen to 
y if you do not 
want users to receive a confirmation message for call transfers.
nIntegrated Services Digital Network Basic Rate Interface (ISDN-BRI)
When an ISDN-BRI telephone, assigned with the Select Last Used 
Appearance field set to 
y, completes a transfer while off-hook using the 
handset, the user is left listening to dial tone on the last-used appearance.
nInternal Automatic Answer
Transferred calls can be answered automatically via IAA.
nQSIG Networking
If calls over an ISDN-PRI trunk are administered for Supplementary QSIG, 
then additional call information may display.
nStation
When a multifunction telephone dials enough digits to route a call, but the 
call could route differently if additional digits were dialed, the telephone 
does not recognize the Conference or Transfer buttons. The user must delay 
dialing for 3 seconds or dial # to indicate that the call can be routed based 
on the digits already dialed. The Conference or Transfer buttons then are 
recognized and the switch completes the operation.
