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. 
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.

398 Default Dialing 
15
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).
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.

Managing data calls 
399 Alphanumeric Dialing 
15
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 1129 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.
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.

400 Data Hotline 
15
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 478 
for more information.
Considerations
NOTE:
Alphanumeric dialing does not apply to endpoints with Hayes modems.
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 1129 for more information.
2. On the Station screen, administer the following fields. Refer to ‘‘
Station’’ 
on page 882 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.
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 619 for 
more information.
nOn the Class of Service screen, administer the Data Privacy field. 
Refer to ‘‘
Class of Service’’ on page 532 for more information.
2. On the Station screen, administer the Class of Service field. Refer to 
‘‘
Station’’ on page 882 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.

402 Data Restriction 
15
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.
nIntercom — Automatic and Dial
An extension with Data Privacy or Data Restriction active cannot originate 
an intercom call. The user receives an intercept tone.
nMusic-on-Hold Access
If a user places a call with Data Privacy on hold, the user must withhold 
Music-on-Hold to prevent the transmission of tones that a connected data 
service might falsely interpret as a data transmission.
nPriority Calls
If a user activates Data Privacy, Priority Calls are denied on analog 
telephones. However, Priority Calls appear on the next available line 
appearance on multiappearance telephones.
Data Restriction
Data Restriction protects analog-data calls from being disturbed by any of the 
system’s overriding or ringing features or system-generated tones.
Data Restriction applies to both voice and data calls.
Once you administer Data Restriction for an analog or multiappearance telephone 
or trunk group, the feature is active on all calls to or from the terminal or trunk 
group.
NOTE:
Do not assign Data Restriction to attendant consoles.

404 Data-Only Off-Premises Extensions 
15
nPriority Calls
Priority Calls are allowed if the analog station is idle. Call Waiting 
(including Priority Call Waiting) is denied if the station is busy. However, 
Priority Calls appear on the next available line appearance on 
multiappearance telephones.
nService Observing
A data-restricted call cannot be service observed.
Data-Only Off-Premises Extensions
Data-Only Off-Premises Extensions allows users to make data calls involving data 
communications equipment (DCE) or digital terminal equipment (DTE) located 
remotely from the system site.
A Data-Only Off-Premises Extension uses an on-premises modular trunk data 
module (MTDM). The system communicates with remote data equipment through 
the private-line facility linking the on-premises MTDM and the remote data 
equipment.
Users can place data calls to this type of data endpoint using Telephone Dialing or 
Data Terminal (Keyboard) Dialing. Since there is no telephone at the remote site, 
originate data calls from the remote data terminal using Keyboard Dialing only.
Administering Data-Only Off-Premises 
Extensions
1. On the Processor/Trunk Data Module screen, administer all fields. 
Refer to ‘‘
Data modules’’ on page 558 for more information.
Considerations
nThe system does not support communications between two TDMs. Modem 
Pooling is similar to a TDM, it cannot be used on calls to or from a 
Data-Only Off-Premises Extension.
Interactions
nTelephone Dialing
An on-premises multiappearance telephone may have a Data Extension 
button associated with the TDM used for a Data-Only Off-Premises 
Extension. The telephone user and the remote user share control of the data 
module. Actions of the user at the telephone may affect the remote user.

— 1-Button Transfer to Data
The telephone user can transfer a call to the Data-Only Off-Premises 
Extension. The Data Extension button lamp on the telephone lights 
and the Call in Progress lamp on the data module lights during a 
data call.
— Data Call Preindication
The multiappearance telephone user presses the idle associated Data 
Extension button to reserve a data module. The data module is busy 
to all other users. When the user reserves a data module, the lamp 
associated with the Data Extension button winks and lights at any 
other associated telephones. A remote user receives the BUSY 
message when attempting to originate a call.
— Return-to-Voice
To establish a data call, the telephone user presses the associated 
busy Data Extension button to transfer the call to the telephone. The 
data module associated with the Data Extension button is 
disconnected from the call. The Call in Progress lamp on the data 
module goes dark.
Data Modules — general
A Data Module is a connection device between a basic-rate interface (BRI) or 
digital-communications protocol (DCP) interface of the switch and data-terminal 
equipment (DTE) or data-communications equipment (DCE).
The following types of data modules can be used with the system:
nAnnouncement data module
nData line data module
nProcessor/trunk data module (P/TDM)
nNetcon data module (G3si configurations only) Refer to DEFINITY ECS 
Administration for Network Connectivity for more information.
nProcessor interface data module (G3si configurations only). Refer to the 
DEFINITY ECS Administration for Network Connectivity for more 
information.

NOTE:
The 51X series Business Communications Terminals (BCTs) are not 
administered on the Data Module screen. The 510 BCT (equivalent to a 
7405D with a display and built-in DTDM), 515 BCT (equivalent to a 7403D 
integrated with 7405D display module function, data terminal and built-in 
DTDM), and the 7505D, 7506D, and 7507D have a DCP interface but have 
built-in data module functionality. Both are administered through the Station 
screen.
Detailed description of data modules
TTI allows data modules without hardware translation to merge with an 
appropriate data module connected to an unadministered port. The 
unadministered port is given TTI default translation sufficient to allow a terminal 
connected to the data module (connected to the port) to request a TTI merge with 
the extension of a data module administered without hardware translation. 
NOTE:
TTI is not useful for Announcement and X.25 hardware. 
Administration Without Hardware supports PDM, TDM, Data-Line, 
Announcement, and X.25 data modules.
NOTE:
The 513 BCT has an EIA interface rather than a DCP interface (no built in 
data module, attachable telephone, or telephone features). The 513 BCT is 
not administered; only the data module to which the 513 BCT is connected 
is administered.
7400A/7400B+/8400B+ Data Module
Use the 7400A data module instead of an MTDM when you support combined 
Modem Pooling. The 7400A data module supports asynchronous operation at 
speeds up to 19200-bps, and provides a DCP interface to the switch and an EIA 
232C interface to the associated modem. The 7400A operates in stand-alone mode 
as a data module.
7400B+ and 8400B+ data modules support asynchronous-data communications 
and operate in stand-alone mode for data-only service or in linked mode, which 
provides simultaneous voice and data service. The 7400B+ and 8400B+ provide 
voice and data communications to 7400D series phones and 602A1
