DCP data modules
Data-terminal dialing 
DCP data-terminal dialing allows a user to set up and disconnect data calls 
directly from a data terminal as follows.
1. At the DIAL: prompt, the user types the data number. The message 
RINGING displays.
2. If the call is queued, the message WAIT, XX IN QUEUE displays. The 
queue position XX updates as the call moves up in queue.
3. To originate and disconnect a call, the user presses BREAK. If the terminal 
does not generate a 2-second continuous break signal, the user can press 
originate/disconnect on the data module.
4. The user can enter digits at the DIAL: prompt.
Telephone dialing 
DCP telephone dialing allows telephone users to originate and control data calls 
from a telephone.
Users can set up a call using any unrestricted telephone and then transfer the call 
to a data endpoint. 
The primary way to make data calls is with multiappearance telephone 
data-extension buttons. Assign any administrable feature button as a 
data-extension button. The data-extension button provides one-touch access to a 
data module. The number of assigned data-extension buttons per telephone is not 
limited.
The following options, either alone or combined, permit flexibility in making data 
calls from a telephone.
nOne-Button Transfer to Data
A user can transfer a call to the associated data module by pressing the 
data-extension button after the endpoint answers.
nReturn-to-Voice
A user can change the connection from data to voice. The user presses the 
data-extension button associated with the busy data module. If the user 
hangs up, the call disconnects. Return of a data call to the telephone implies 
that the same data call is continued in the voice mode, or transferred to 
point.
The Return-to-Voice feature is denied for analog adjuncts.

nData Call Preindication
A user, before dialing a data endpoint, can reserve the associated data 
module by pressing the data-extension button. This ensures that a 
conversion resource, if needed, and the data module are reserved for the 
call. Use of Data Call Preindication before 1-button transfer to data is 
recommended for data calls that use toll-network facilities. Data Call 
Preindication is in effect until the associated data-extension button is 
pressed again for a 1-button transfer; there is no time-out.
ISDN-BRI data modules
Data-terminal dialing
A user can set up and disconnect data calls directly from a data terminal without 
using a telephone as follows:
1. The user presses 
ENTER a few times. If the CMD: prompt does not appear, 
the user presses 
BREAK A + T at the same time, and then presses ENTER.
2. At the CMD: prompt, the user types and presses 
ENTER.
3. To disconnect, the user enters +++. At the CMD: prompt, the user types 
end and presses
 ENTER.
Telephone dialing
To make a data call, an ISDN-BRI phone user presses the data button on the 
terminal, enters the number on the dial pad, and then presses the data button again.
The following data functions are not available on ISDN-BRI phones:
nOne-Button Transfer to Data
nReturn-to-Voice
nData Call Preindication
nVoice-Call Transfer to Data and Data-Call Transfer to Voice
The system handles all presently defined BRI bearer data-call requests. Some 
capabilities that are not supported by Lucent terminals are provided by 
non-Lucent terminals. If the switch does not support a capability, a proper cause 
value returns to the terminal.
BRI terminals receive a cause or reason code that identifies why a call is being 
cleared. The BRI data module converts certain cause values to text messages for 
display.

412 Data Call Setup 
15
In a passive-bus multipoint configuration, the system supports two BRI endpoints 
per port, thus doubling the capacity of the BRI circuit pack. When you change the 
configuration of a BRI from point-to-point to multipoint, the original endpoint 
does not need to reinitialize. Only endpoints that support service profile identifier 
(SPID) initialization can be administered in a multipoint configuration.
Analog modems
When a telephone user places a data call with a modem, the user dials the 
data-origination access code assigned in the system before dialing the endpoint.
Considerations
nA BRI phone cannot call a data terminal, and a data terminal cannot call a 
BRI phone.
Interactions 
nAbbreviated Dialing
Only 22 of the 24 (maximum) digits in an abbreviated-dialing number are 
available for keyboard dialing. The remaining two digits must contain the 
wait indicator for tone detection.
nCall Coverage
A hunt group made up of data endpoints cannot be assigned a coverage 
path.
nCall Detail Recording
CDR records the use of modem pools on trunk calls.
nCall Forwarding All Calls
Calls received by a data module can be forwarded. Activate Call 
Forwarding All Calls with data-terminal (keyboard) dialing. If the 
forwarded-to endpoint is an analog endpoint and the caller is a digital 
endpoint, modem pooling is activated automatically.
nPooled Modems with Hunt Groups
UCD can provide a group of data modules or analog modems for 
answering calls to connected facilities (for example, computer ports).

413 Default Dialing 
15
nWorld-Class Tone Detection
Multiple-line data-terminal dialing is supported if the administered level of 
tone detection is precise. You can administer tone-detection options. The 
message that Data Call Setup sends to users varies according to the option.
If the option is not set to precise, and a data call is set up over an analog 
trunk, messages describing the status of the called endpoint (for example, 
RINGING, BUSY, TRY AGAIN) change according to which 
tone-detection option is selected.
Default Dialing
Default Dialing provides data-terminal users who dial a specific number the 
majority of the time a very simple method of dialing that number. Normal data 
terminal dialing and alphanumeric dialing are unaffected.
Default Dialing enhances data terminal (keyboard) dialing by allowing a 
data-terminal user to place a data call to a preadministered destination by either 
pressing a 
Return at the DIAL: prompt (for data terminals using DCP data modules) 
or typing 
d and pressing RETURN at the CMD: prompt (for data terminals using 
ISDN-BRI data modules). The data-terminal user with a DCP data module can 
place calls to other destinations by entering the complete address after the DIAL: 
prompt (normal data terminal dialing or alphanumeric dialing). The data-terminal 
user with an ISDN-BRI data module can place calls to other destinations by 
typing 
d, a space, the complete address, and press RETURN after the CMD: prompt.
NOTE:
DU-type hunt groups connecting the system to a terminal server on a host 
computer have hunt-group extensions set to no keyboard dialing.
For the AT command interface supported by the 7400A/7400B/8400B data 
module, to dial the default destination, enter the ATD command (rather than press 
return).
Administering Default Dialing
1. You can use an abbreviated dialing list for your default ID. Refer to 
‘‘
Abbreviated Dialing’’ on page 1139 for more information.
2. On the Data Module screen, administer the following fields:
nSpecial Dialing Option as default.
nAbbreviated Dialing List, enter the list to use.
nAD Dial Code.

Managing data calls 
414 Alphanumeric Dialing 
15
Alphanumeric Dialing
Alphanumeric Dialing enhances data-terminal dialing by allowing users to place 
data calls by entering an alphanumeric name rather than a long string of numbers.
For example, a user could type 9+1-800-telefon instead of 9+1-800-835-3366 to 
make a call. Users need to remember only the alpha-name of the far-end 
terminating point.
Alphanumeric Dialing allows you to change a mapped string (digit-dialing 
address) without having to inform all users of a changed dial address. Users dial 
the alpha name.
When a user enters an alphanumeric name, the system converts the name to a 
sequence of digits according to an alphanumeric-dialing table. If the entered name 
is not found in the table, the system denies the call attempt and the user receives 
either an 
Invalid Address message (DCP) or a Wrong Address message 
(ISDN-BRI).
Because data terminals access the switch via DCP or ISDN-BRI data modules, 
dialing procedures vary: 
nFor DCP, at the DIAL: prompt users type the alphanumeric name and press 
RETURN. 
nFor ISDN-BRI, at the CMD: prompt users type d, a space, and the 
alphanumeric name, and press 
RETURN.
More than one alphanumeric name can refer to the same digit string.
Administering Alphanumeric Dialing
1. On the Alphanumeric Dialing Table screen, administer the Alpha-name and 
Mapped String fields. Refer to ‘‘
Alphanumeric Dialing Table’’ on page 491 
for more information.
Considerations
NOTE:
Alphanumeric dialing does not apply to endpoints with Hayes modems.

415 Data Hotline 
15
Data Hotline
Data Hotline provides for automatic-nondial placement of a data call preassigned 
to an endpoint when the originating switch goes off-hook. Use for security 
purposes.
Administering Data Hotline
1. You can use an abbreviated dialing list for your default ID. Refer to 
‘‘
Abbreviated Dialing’’ on page 1139 for more information.
2. On the Station screen, administer the following fields. Refer to ‘‘
Station’’ 
on page 894 for more information.
nAbbreviated Dialing List
nSpecial Dialing Option
nHot Line Destination
3. On the Data Module screen, administer the Abbreviated Dialing List1 field.
The system automatically places Data Hotline calls to preassigned extensions or 
off-premises numbers. Calling terminals are connected to the system by a data 
module. Users should store the destination number in the abbreviated dialing list 
for future reference.
Interactions
nCall Forwarding — All Calls
A Data Hotline caller cannot activate both Call Forwarding and Data 
Hotline. Dialing the Call Forwarding feature access code (FAC) causes 
activation of the Data Hotline instead.

416 Data Privacy 
15
Data Privacy
Data Privacy protects analog data calls from being disturbed by any of the 
system’s overriding or ringing features.
Administering Data Privacy
1. Choose either of the following:
nOn the Feature Access Code screen, administer the Data Privacy 
Access Code field. Refer to ‘‘
Feature Access Code’’ on page 633 for 
more information.
nOn the Class of Service screen, administer the Data Privacy field. 
Refer to ‘‘
Class of Service’’ on page 545 for more information.
2. On the Station screen, administer the Class of Service field. Refer to 
‘‘
Station’’ on page 894 for more information.
To activate this feature, the user dials the activation code at the beginning of the 
call.
Considerations
nData Privacy applies to both voice and data calls. You can activate Data 
Privacy on Remote Access calls, but not on other incoming trunk calls. 
Data Privacy is canceled if a user transfers a call, is added to a conference 
call, is bridged onto a call, or disconnects from a call. You can activate 
Data Privacy on calls originated from attendant consoles.
Interactions
nAttendant Call Waiting and Call Waiting Termination
If Data Privacy is active, Call Waiting is denied.
nBridged Call Appearance — Single-Line Telephone
If you activate Data Privacy or assign Data Restriction to a station involved 
in a bridged call and the primary terminal or bridging user attempts to 
bridge onto the call, this action overrides Data Privacy and Data 
Restriction.
nBusy Verification
Busy Verification cannot be active when Data Privacy is active.
