							Park
Park
Description
This feature allows a user to put a call into a special hold/parked condition so that it can be
picked up from any voice terminal in the system.It is used in three typical applications:
l Basic Park: A user parks a call and then picks it up at another voice terminal.
l Meet-Me-Conference:A conference member parks the conference and pages
another employee to join the conference.
l Transfer: A user parks a call and then pages another employee to pick up the call.
A user parks a call by first putting it on hold and then dialing the Park code ( V 5 ). The call
can subsequently be retrieved from any voice terminal by dialing the Park retrieval code ( V 8 )
and the PDC of the parking station.In addition, any user active in a conference involving
fewer than five members may park the conference so that another user may join by dialing
V 8 and the parked-on number.
A multiline voice terminal user invokes Park by pressing HOLD to place a call or conference
on hold, then pressing an idle System Access button and dialing V 5. A single-line voice
terminal user invokes the feature by pressing the switchhook to place the call or conference
on hold, then dialing V 5.If the call is successfully parked, the user receives confirmation
tone and then recall dial tone. If the call cannot be parked, reorder tone is received. In the
latter case, to return to the held call, the user presses the held call button (multiline sets) or
flashes the switchhook (single-line sets).
The parking station may return to a parked call or conference without affecting the park
state. The multiline voice terminal user may return by pressing the held call button. The
single-line user may return by flashing the switchhook.
When the single-line user goes on-hook, the parked call is removed from the terminal and
cannot be reentered.
To retrieve a parked call, a user must obtain system dial tone, dial V 8 and then dial the PDC
of the station that parked the call.If the call is not retrieved within an administered interval
(default = 2 minutes) the call will return to the user that parked the call. At multiline voice
terminals, returning calls always ring at System Access (SA) buttons, regardless of the type
of button on which the parked call arrived originally. If no idle SA button is available, calls
attempting to return will remain parked until one becomes idle.
Note:Multiline voice terminals without SA buttons cannot park calls (they receive
reorder tone when they try to do so). However, in a principal station/bridging
station arrangement, a bridging station without SA buttons can park calls on
its Bridged Access buttons because returning calls would ring at the principal
station.
An attendant can park a call with the same procedure as a multiline voice terminal user. In
addition, if the Attendant Position is equipped with a Selector Console, up to eight trunk calls
can be parked on DXS buttons dedicated to the Park function. The attendant parks a call by
2-249 
						

							FEATURES AND SERVICES
pressing an idle Park button.The status LED of the parked line on the Attendant Console
winks and the status LED of the Park button on the Selector Console lights steadily. A call
parked with the Selector Console is retrieved by dialing V 8 and the access code assigned to
the dedicated Park button.
A call parked by the attendant using the same procedure as a multiline voice terminal user
will return to a SA button on a Direct Trunk Attendant Console (DTAC) or a LOOP button on
a Switched Loop Attendant Console (SLAC) if it is not picked up within the administered
return interval. A call parked on the Selector Console but not picked up within the interval
will return to the RTN-DA button (DTAC) or a LOOP button (SLAC), in the same manner as
any other unanswered call.
Each voice terminal user (except an attendant with a Selector Console) can only park one
call at a time: a maximum of 24 calls can be parked in the system at one time. A call is no
longer parked when it is answered, when it returns to the parking terminal, or when it is
abandoned by the caller.
Considerations
Park can be used whenever a user engaged on a call needs to go elsewhere, and wishes to
complete the call from another terminal.Park also allows users to answer a call from any
voice terminal when paged.
In order to use the Park feature, a station must have at least one System Access button.
Interactions
The following features interact with Park.
Attendant Direct Extension Selection: Station-to-Station calls cannot be parked via the Park
buttons on the Attendant Selector Console.
Attendant Position Busy:If a call is parked on an attendant console and the attendant
console enters Position Busy mode, the parked call will return to the inactive console if not
answered within the administered interval (default = 2 minutes).
If a call is parked on the Selector Console by a Switched Loop attendant and the SLAC is
placed in the Position Busy mode, the parked call will return to the other active attendant
console, if not answered within the administered interval.
Bridging of System Access Buttons:A call parked by a principal station having bridged call
appearances at a bridging station must be retrieved by dialing V 8 and the PDC of the
principal station. The principal station and the bridging station can enter the call without
affecting its parked state.If the call returns, it can be answered at the principal station or on
a bridged appearance.
If a bridging station is active on a bridged call appearance and activates Park, the call is
parked on the Personal Dial Code (PDC) number of the principal station, not of the bridging
station. If the parked call is not answered, it will return on the principal’s SA button.

							Park
Callback Queuing: Queued calls cannot be parked unless they are part of a conference.
Reorder tone is returned whenever an illegal park is attempted, but the queued call is not
disconnected. If parked conference members drop out, leaving only a queued call, it will be
disconnected to prevent the illegal condition of a single queued call being parked.
Calling Restrictions:If the parking station is outward restricted or toll restricted, the recall
dial tone following a successful park cannot be used to avoid the restriction.
Conference:Parked conference calls do not return to the parking voice terminal. They
remain parked.Park may be used to place a conference on hold if it contains fewer than five
parties.
Display: When a parked call returns to a display station, screen 1 contains redirection symbol
“}” and PARK RTN; screen 2 contains calling party identification.
Exclusion: A call cannot be parked, and a parked call cannot be answered, if the Exclusion
feature is invoked on that call.
Intercept Treatment With Reorder Tone:An unsuccessful attempt to park a call due to
misdialing or attempting to park more than one call at a voice terminal results in Reorder
Tone.
Music-On-Hold: Parked calls (except conferences) receive music.
Personal Line: A parked Personal Line is bridgeable by any user with a button appearance
of that line. Bridging on to the connection does not answer the parked call. The parked call
will not return to the parking voice terminal user in this case.
Remote Access: Remote Access callers cannot use the Park feature.
Transfer: Single-line voice terminals cannot transfer parked calls.
Administration Requirements
Special Feature Port, Attendant Selector Console:
l Assign selector console Park codes.
l Number of seconds before Park return (0-240; default = 120).

							FEATURES AND SERVICES
Personal Dial Code (PDC)
Description
A Personal Dial Code (PDC) consisting of one to four digits is assigned to each voice
terminal in the system.The PDC serves as the “extension number” of its terminal. Each
PDC can also be associated, through system administration, with the name of the terminal’s
user; terminals that have no specific users, such as lobby or conference room sets, can be
assigned appropriate place or function names.
A special quality of PDCs is their portability; users can “carry” their PDCs with them when
they temporarily go to another terminal. A user can “sign in” his or her PDC at “away”
terminals and receive calls originally directed to the home terminal. Upon leaving the
temporary location, the user “signs out”the PDC so that calls will again ring at the home
terminal. (For information on the applications of these procedures, refer to the “Following”
feature description.)
Analog data endpoints with modems are also assigned PDCs.
Digital data endpoints have
Data Dial Codes (DDCs).
Floating Personal Dial Codes (FPDCs) are assigned to users who do not have their own
voice terminals. These users can sign in their FPDCs at any station in the system and
receive their calls there. The system can be administered to force calls to FPDCs that are
not signed in anywhere to ring at the Attendant Console(s). FPDCs can also be reserved and
assigned to visitors who expect to receive calls.
Considerations
The Personal Dial Code (PDC) feature provides flexibility for users and visitors. Visitors,
once assigned a FPDC, can inform callers and the attendant. Calls can then be directed to
the voice terminal where the FPDC is signed in.Calls to FPDCs that are not signed in
anywhere may be directed to the attendant for further handling.
Up to 200 PDCs and 300 FPDCs can be assigned in a system.
Interactions
The following features interact with Personal Dial Code.
Coverage: Calls to a FPDC signed in at a voice terminal receive the coverage of that
terminal. Unanswered calls to a PDC at an away terminal return to the home terminal and
receive the home terminal’s coverage treatment; they do not receive the away terminal’s
coverage.
Direct Inward Dialing:In systems with DID service, PDCs, FPDCs, DGC access codes,
DDCs, and facility access codes may match the last 2, 3 or 4 digits of DID numbers. For
example, the code matching DID number 555-2345 may be 45, 345 or 2345, depending on
the system dial plan.

							Personal Dial Code (PDC)
Direct Station Selection: If an attempt is made to program a FPDC (rather than a PDC) on a
Flex DSS button, Reorder Tone is received.
Display: Calls to a FPDC signed in at a station covered by an attendant console receive
coverage. However,the attendant display will show the PDC and name of the covered
station, not the FPDC.
Administration Requirements
System:
l Route calls for unassigned DID numbers to the Attendant (yes or no; default = yes).
l Route calls for not-signed-in FPDCs to the attendant (yes or no; default = yes).
l Add/Delete FPDCs.

							FEATURES AND SERVICES
Personal Lines
Description
This feature provides a dedicated outside line for multiline voice terminal or ATL cordless
telephone users.
Unlike pooled facilities, which can be accessed via dial codes, Personal Lines can be
accessed only via a dedicated feature button,and provide both incoming and outgoing
service. Up to 16 terminals may share a Personal Line.Up to four parties may be off-hook
on the line at the same time (the line itself is the fifth conferee). When the line is busy, its
status LED lights at all terminals on which the line appears. Ringing may be provided
optionally to one or more of the terminals sharing the line.
For each Personal Line, one station is administered as the principal (owner). The coverage
of that terminal determines the coverage of the Personal Line.
Considerations
Personal Lines provide facilities to users who desire direct access to the exchange network.
In addition, Personal Line appearances are provided on the Direct Trunk Attendant Console
for general use trunks.Appearances of these lines may also be provided at selected
multiline voice terminals to ensure coverage when the attendant is not available. DID trunks
cannot be terminated on Personal Line buttons.
Personal Lines provide direct access for callers, bypassing the attendant. In some cases,
they may substitute for DID service.
Interactions
The following features interact with Personal Line.
Attendant Console, Direct Trunk: On the Direct Trunk Attendant Console (DTAC), trunks are
terminated as Personal Lines.The DTAC can accommodate a maximum of 26 Personal
Lines (24 is the practical limit).
Attendant Console, Switched Loop:Personal Lines cannot be terminated on a Switched
Loop Attendant Console.
Coverage: The coverage of the principal station (owner) determines coverage for the line.
Direct Group Calling: The same trunk may be used as a Personal Line and also be directed
to a DGC group.If an incoming call is not answered by the DGC group after a
predetermined number of rings, ringing and LED flashing will be transferred to all button
appearances of the line (unless a DGC delay announcement is provided).
Hold: A Personal Line cannot be placed on hold if any other stations that share the line are
also off-hook on the line.
2-254 
						

							Personal Lines
Line Selection (Prime Line Preference):Prime Line Preference may be assigned to a
Personal Line.
Park: A parked Personal Line is bridgeable by any user with a button appearance of that
line. Bridging on to the connection does not unpark the call; in this case, the parked call will
not return to the parking user.
Pickup: After a call is picked up from a Personal Line button, the called terminal can still
enter the call.
Pooled facility: A Personal Line may also be a member of a pooled facility group.
Toll Restriction (see “Calling Restrictions”): A call over a Personal Line is subject to the toll
restrictions of the station on which the call was placed.
Administration Requirements
Voice Terminal Port:
l Assign Personal Line trunk number.
l Assign Personal Line feature button.
l Make this the Principal Station (yes or no).
l Enable Personal Line Ringing (yes or no).

							FEATURES AND SERVICES
Pickup
Description
This feature allows a user to answer a call ringing at another voice terminal. There are two
forms of Pickup: (1) Directed and (2) Group.
Directed Pickup:
Directed Pickup allows calls to other voice terminals, including Automatic Intercom calls and
calls ringing at coverage buttons. to be “picked up” by dialing the Pickup code ( V 7 ) and the
ringing terminal’s PDC.Picked-up calls remain accessible at the call appearance button of
multiline terminals, but are no longer available at single-line terminals.
A ringing call can be answered at a busy single-line voice terminal by pressing the
switchhook, which will place the current call on hold, dialing V 7, and the ringing voice
terminal’s PDC.
This is a standard feature available at every voice terminal. No administration is required.
Also, this feature cannot be turned off or restricted.
Group Pickup:
Group Pickup permits calls to another terminal in the Pickup group to be answered. Any
ringing call, including Automatic Intercom and coverage calls, is eligible for Pickup.
A member of a Pickup Group can answer any call to any other member of the group by
dialing the Group Pickup code ( V 70 ).
Up to 16 groups (with up to 16 voice terminals in each group) can be set up. Each Pickup
group can have a maximum of two simultaneous ringing calls eligible for Pickup treatment at
a time, and the calls are picked up in order of arrival.A user can be assigned to only one
Pickup Group.
Considerations
With Pickup, users do not have to leave their own voice terminal to answer a call at a nearby
voice terminal.Instead, a user simply lifts the handset and dials an access code. This
allows calls that may go unanswered to be handled quickly and efficiently.
The call must be administered to ring at the voice terminal for which Pickup is attempted.
Otherwise the attempt will be blocked.
If the picked-up call was to a multiline terminal, the called terminal can still enter the call. If
the called terminal was a single-line terminal, it cannot enter the call once it is picked up.
Pickup cannot be invoked after the call has been answered.
2-256 
						

							Pickup
If no eligible calls are ringing, attempting pickup results in reorder tone.
Interactions
The following features interact with Pickup.
Bridging of System Access Buttons: Pickup is a station-oriented feature. Thus, calls ringing at a
principal System Access (SA) button can be picked up by members of the principal’s Pickup Group;
calls ringing at a Bridged Access (BA) button can be picked up by members of the bridging station’s
Pickup Group. If a user dials the Group Pickup access code while active on a BA button, the system
interprets this as an attempt to pick up a call in the Pickup Group of the bridging station, not of the
principal station.
Calls ringing at either a principal SA button or an associated BA button can be picked up by using
the Directed Pickup feature.
Callback Queuing: A callback call cannot be picked up.
Coverage: When a call is directed to a coverage station and the call is
Cover buttons associated with the call go idle.
Personal Line: After a call is picked up from a Personal Line (PERS
terminal can still enter the call.
Remote Access: Remote Access callers cannot use the Pickup feature.

							Features and Services
Pooled Facility - Dial Access
Description
This feature allows multiline and single-line voice terminal and ATL cordless telephone users to
access a common pool of trunks by dialing a facility access code.
Up to 16 facility access codes can be assigned (one per trunk group). The codes can be one to four
digits in length. A group of similar trunks assigned the same access code is referred to as a trunk
group. Additional information is provided in the “Trunk Groups” feature description.
After going off-hook on a System Access or Loop button, receiving system dial tone, and dialing a
facility access code, the user will be connected to an idle trunk. (However, the connection will not
be made if the terminal is restricted from dialing this trunk group or if dial access is restricted, in
general, to trunks in the group.) The LEDs associated with the System Access button will be lighted,
and the user may complete the call. Single-line users do not receive LED indications of the status
of the pool. An attempt to originate a call on a busy facility will result in Reorder Tone (fast busy).
Considerations
Pooled Facility-Dial Access provides users of single-line terminals, or multiline voice terminals
without Direct Facility Access (FACILITY) buttons, access to the system’s pooled facilities.
Interactions
The following features interact with Pooled Facility-Dial Access.
Bridging of System Access Buttons: A station originating a call on a Bridged Access button and
using a facility access code is granted access to that pool according to the Calling Restrictions
assigned to the bridging station, not the principal station.
Direct Inward Dialing (DID): Access to pooled facilities via DID is permitted. This includes access
to WATS, FX, tie trunks, private lines, dictation equipment, and paging systems. This access is
provided by selecting facility access codes so that they will match DID numbers.
Equal Access: Equal Access calls are allowed from toll restricted stations that have outward calling
capability via pooled facilities (701 and 801 trunks) administered with “ORIGINATING LINE
Screening”. Originating Line Screening is a service provided by the Local Exchange Carrier (LEC)
identifying the call as one which should not have the operator bill the originating facility.
Outward and Facility Access Restriction (see “Calling Restrictions”): A terminal can be denied
dial access to some or all pooled facilities, or may be totally restricted from making any outside
calls.
Toll Restriction (See “Calling Restrictions”): Denies the use of pooled facilities for certain toll
calls, but does not block access to the pooled facilities.
