Figure 57. DCP PC interface configuration (Group 1)
The group 2 configurations link to the switch using a PC/ISDN Interface card 
installed in the PC. This group can include a stand-alone PC terminal, or up to 4 
phones, handsets, or headsets. Group 2 (shown in Figure 58
) uses PC/ISDN 
Interface cards (up to four cards) which plug into expansion slots on the PC. 
These cards each provide 2 standard 8-pin modular-jack connections for both line 
connections (to the switch) and phone connections. A standard 4-pin modular jack 
is also available for use with a handset or headset.

Figure 58. ISDN—BRI PC interface configuration (Group 2)
PC Interface users have multiple appearances (depending on the software 
application used) for their assigned extension. Designate one or more of these 
appearances for use with data calls. With the ISDN-BRI version, you can use up 
to 4 separate PC/ISDN Interface cards on the same PC. Assign each card a 
separate extension, and assign each extension one or more appearances. The 
availability of specific features depends on the COS of the extension and the COS 
for the switch. Modem Pooling is provided to ensure general availability of off-net 
data-calling services.

Security
There are two areas where unauthorized use may occur with this feature: 
unauthorized local use and remote access.
!SECURITY ALERT:
Unauthorized local use involves unauthorized users who attempt to make 
calls from a PC. The PC software has a security setting so users can place 
the PC in Security Mode when it is unattended. You can also assign 
Automatic Security so that the administration program on the PC is always 
active and runs in Security Mode. This mode is password-protected.
!SECURITY ALERT:
Remote access involves remote access to the PC over a data extension. 
Remote users can delete or copy PC files with this feature. You can 
password-protect this feature. Consult the BCS Product Security Handbook 
for additional steps to secure your system and to find out about obtaining 
information regularly about security developments.
Considerations
nUse the Function Key Module of the 7405D with PC Interface.
nBRI terminals normally are initializing terminals and require you to assign 
an SPID. The PC/ISDN Platform (Group 2), in a stand-alone configuration, 
is a noninitializing BRI terminal and does not require you to assign a SPID.
— Set a locally-defined terminal type with General Terminal 
Administration
— Define the terminal type as a noninitializing terminal that does not 
support Management Information Messages (MIM).
— Assign the PC/ISDN Platform with an associated (initializing) 
ISDN-BRI phone (such as an ISDN 7505) using a SPID.
— Assign the station (using a locally-defined terminal type) to take full 
advantage of the capabilities of the PC Interface. This terminal type 
is also noninitializing with no support of MIMs.
nDo not use phones with data modules with the PC Interface. (You can still 
use 3270 Data Modules if you also use 3270 emulation). If you attach a 
DCP data module or ISDN data module to a phone that is connected to a 
PC Interface card, the data module is bypassed (not used). All the interface 
functions are performed by the interface card even if a data module is 
present.

nThe 7404D phone with messaging cartridge cannot be used with PC 
Interface. However, the 7404D with PC cartridge can be used, but only 
with Group 1 configurations.
Interactions
nData Communications Access
PC Interface uses a digital interface and is not directly compatible with 
Data Communications Access, which uses an analog interface. Apply 
Modem Pooling conversion if you use these features together.
nData Protection
Assign Data Protection—Permanent for use with PC Interface for data 
communications.
nHost Computer Access
Both PC Interface and Host Computer Access use digital interfaces. These 
features are compatible and Modem Pooling conversion is unnecessary.
nISDN-BRI 
Each card can have its own separate phone or voice-calling device. A 
phone does not require special application software on the PC. However, a 
handset or headset alone requires special application software.
nModem Pooling
Use Modem Pooling if you use PC Interface to place calls to, or receive 
calls from, off-premises stations over analog trunks.
Personal Station Access
Personal Station Access (PSA) allows users to associate the preferences and 
permissions of their telephone with any other telephone of the same type. 
PSA makes it convenient for different users to use the same bank of phones at 
different times. For example, several telecommuting or hoteling employees can 
use the same office on different days of the week. The employees use PSA to 
“associate” with the office phone — that is, make the terminal “theirs” for the day. 
Calls an employee originates from the station are recognized and displayed as the 
employee’s calls, and calls routed to the employee’s extension route to the voice 
terminal “associated” with that extension.

A telecommuting or hoteling employee can also use PSA when working at home. 
For example, the employee installs a DCP terminal and a DEFINITY Extender at 
home, calls into the system, and uses PSA to associate the remote phone with their 
extension. The system associates the home terminal — that is, recognizes the 
home terminal as having the employee’s preferences and permissions. When 
someone calls the employee’s extension, the call rings at the employee’s home. 
When the employee no longer needs to use the office, they “dissociate” from the 
terminal. 
PSA requires users to enter a security code and can be used on-site or off-site. 
PSA-invalid attempts generate referral calls and are recorded by Security 
Violation Notification (SVN) software, if that feature is enabled. If a user 
interrupts the PSA dialing sequence by pressing the release button or by hanging 
up, the system does not log the action as an invalid attempt.
Detailed description
The preferences and permissions that are retained with PSA include the definition 
of terminal buttons, abbreviated dial lists, and class of service (COS) and class of 
restriction (COR) permissions assigned to the your station. Extensions that do not 
have a COS, such as Expert Agent Selection (EAS) agents or hunt groups, cannot 
use PSA.
PSA functions only on analog, hybrid, and Digital Communications Protocol 
(DCP) terminals. Many types of DCP terminals exist, and these terminals have 
different types and numbers of buttons. If you attempt to associate DCP stations 
with DCP terminals that have incompatible buttons, button mapping is 
unpredictable. This is also true of hybrid terminals. If you want a user to be able to 
use the terminal buttons and to have consistent displays, associate stations with 
terminals of the same type.
Stations and ports on different switches cannot be PSA associated. This includes 
stations on different switches (or nodes) within Distributed Communications The 
system does not limit the number of stations that can use PSA. However, heavy 
use of the associate and dissociate functions may temporarily impact system 
performance.

1472 Personal Station Access 
20
Dissociated telephones 
When a user requests to associate a telephone with PSA, any other telephone 
using that extension is automatically dissociated. It is possible to place emergency 
calls from a dissociated telephone, provided a COR has been assigned to 
dissociated phones on the Feature-Related System Parameters screen. 
PSA allows a dissociate request from a bridged appearance. However, when you 
execute a dissociate command from Terminal B, even if you are on a bridged 
appearance of an extension belonging to Terminal A, you dissociate the station 
belonging to Terminal B.
The dissociate function within PSA allows a user to restrict the features available 
to a phone. When a phone has been dissociated using PSA, it can be used only to 
call an attendant, to place an emergency call, or to accept a Terminal Translation 
Initialization (TTI) or PSA request. To enable users to make other types of calls 
from dissociated sets, you must establish a class of restriction for these phones. 
See ‘‘
Setting up Personal Station Access’’ on page 300 for more information. 
NOTE:
Once a station has been associated with a terminal, anyone using the 
terminal has the capabilities of the associated station. Be sure to execute a 
dissociate request if the terminal can be accessed by unauthorized users. 
This is particularly important if you use PSA and DCP extenders to permit 
remote DCP access.
Interactions
nAdjunct/Switch Application Interface
An ASAI link cannot use this feature because ASAI uses a BRI port. Do 
not assign to an ASAI link a Class of Service that allows PSA.
nBridged Appearance
When you execute a PSA dissociate request for the principal station, its 
bridged appearances remain active if the stations on which they appear 
have not been dissociated. When a call is made to the principal extension, 
any of its bridged appearances that can be alerted are alerted. Otherwise, 
the call follows the principal extension’s coverage path.
PSA dissociate requests executed at a bridged appearance dissociates the 
station that the bridged appearance is on.
nCall Management
PSA dissociate automatically logs out an ACD agent.

nCoverage
PSA does not change coverage path operations. If a station is dissociated, 
its calls still go to coverage unless they are forwarded.
nProperty Management System
A station assigned to a room, rather than to a person who needs to work in 
multiple locations, should not use PSA. Such a station should not have PSA 
in its COS.
nSave Translations
PSA commands cannot be successfully executed during a save translations. 
When a reset 3 or greater (reset 4, reset 5, and so on) occurs on the system, 
all associations revert to their state as of the last save translations.
nSecurity Violation Notification
PSA security violations are tracked and reported by SVN, if it is active.
nTenant Partitioning
If a terminal is already associated, a user attempting a PSA associate 
request at that terminal must specify a station in the same partition as the 
station already associated with the terminal.
However, anyone, in any partition, can execute a PSA dissociate request at 
the terminal (if the associated station has PSA in its COS) and then execute 
a PSA associate request for a station in any tenant partition.

1474 Priority Calling 
20
Priority Calling
Priority Calling provides a special type of call alerting between internal telephone 
users, including the attendant. The called party receives a distinctive ring when 
the calling party uses Priority Calling.
You administer the priority-calling ringing-pattern system wide. Default is a 
3-burst alerting signal. You allow feature use for each telephone user by 
administering the user’s class of service.
The following types of calls are always priority-calling calls:
nCall coverage consult 
nAutomatic callback
nRingback queuing
nAttendant intrusion
nSecurity violation notification
The system generates the call waiting ringback tone that a single-line telephone 
user hears even if the user is active on a call. In contrast, the system does not 
generate the pattern for a multiappearance telephone if there are no idle call 
appearances. In this case the caller hears busy tone. However, the system does 
generate the pattern if the telephone has an idle call appearance, including the one 
reserved for call origination.
Interactions
nAbbreviated Dialing
If a user wants to make a priority call to a number in an abbreviated dial 
list, the Priority Calling access code and the AD code must be programmed 
on one button. If a user attempts to use Abbreviated Dialing (either by 
button or FAC) after dialing the Priority Access Code, the system denies 
the call.
nCall Coverage
Priority Calling calls do not redirect to coverage unless the caller activates 
Go to Cover. If the call redirects, it remains a priority call, and the covering 
user receives a distinctive (default is three-burst) ringing signal.
nCall Forwarding All Calls
Priority Calling calls (except callback calls) are forwarded, and the 
forwarded call remains a priority call.

nCall Vectoring
The system generates intercept tone when someone attempts to activate 
Priority Calling toward a Vector Directory Number (VDN).
nCall Waiting
A Priority Calling call waits on an active single-line telephone even if Call 
Waiting is not assigned to the telephone. The active, single-line telephone 
user receiving the call hears a distinctive (default is three-burst) priority 
Call Waiting tone.
nConsult
A Consult call acts as a priority call and waits at a single-line telephone, 
even if the telephone does not have Call Waiting Indication assigned.
nDistributed Communications System
On a DCS tandem call to a single-line telephone, the called party does not 
receive priority ringing if the caller activates Priority Calling by pressing 
the priority button after making a call.
nLast Number Dialed
If a priority call is to be made to the last number dialed, the Last Number 
Dialed button must be used. The Last Number Dialed feature access code is 
not valid after Priority Calling has been activated.
Single-line telephones (2500 series) can be administered so that distinctive 
signals are not provided. In this case, 1-burst ringing is provided for 
priority calls.

1476 Pull Transfer 
20
Pull Transfer
Pull Transfer allows either the transferring or transferred-to party to press the 
Transfer button to complete the transfer operation.
When attendants control calls, called parties cannot use Pull Transfer. Attendants 
who are called parties cannot use Pull Transfer. When attendants have parties on 
hold they are transferred with the standard transfer process.
To use Pull Transfer, calling parties and called parties must be on the same switch, 
or called parties must be reached via Italian TGU/TGE tie trunks.
Called parties using analog telephones flash the switchhook or press the flash key 
or recall button to transfer calls. Called parties using digital phones press the 
transfer key to complete transfers.
Interactions
nAnalog Station Recall Operation and Feature Activation
When called parties initiate either analog-telephone recall or feature 
activation, callers are not put on hold for transfer, they are transferred via 
Pull Transfer.
nBRI telephones
Callers using BRI Stations reach desired parties through an intermediate 
step by calling a party who calls a final destination. Intermediate parties 
activate pull transfer to complete transfers. Final called parties go off hook 
as if a new transfer was originated.
nCall Detail Recording
The switch checks to ensure that calls are correctly recorded with CDR 
when Pull Transfer is completed.
nDigital Station Transfer Operation
When called parties initiate transfer operations, callers are not put on hold 
for transfer; they are transferred via Pull Transfer.
nNon-BRI telephones:
Callers using Non-BRI telephones reach desired parties through an 
intermediate step by calling a party who calls a final destination. Each 
called party activates pull transfer.
