eXtra Device Port (XDP)
The Digital System Telephone has a special jack, called XDP, to which you can
connect any single line device, including a PC with modem. They may have
different extension numbers (Independent Mode), or share the same one
(Parallel Mode).
• In the Independent Mode, you can, for instance, transmit data while
talking on the phone. Simply put, XDP doubles extension capacity of the
system without any additional cost.
• In the Parallel Mode, you can answer a call from either the Digital
System Telephone or the connected device (e.g., a cordless telephone).
Calls can be transferred easily between the two devices, simply by going
off-hook. When a PC is connected, you can dial from the PC using its
database and talk with the Digital System Telephone by simply lifting the
If you do not use XDP jack on the Digital System Telephone, it is possible to
install a Single Line Telephone by wiring from the main unit directly as
Independent or Parallel Mode.

Call Distribution
The KX-TD612 supports many advanced digital functions one of those will
distribute incoming outside calls automatically for you. By analysing
DDI/MSN*1 numbers or CLIP*2 information, the system can direct calls to
ring specific extensions only.
Sixty Call Distribution Patterns (Handling Tables) can be programmed.
Maximum of 500 CLIP numbers and 200 DDI/MSN numbers
(consisting of up to 32 digits) can be registered, and each registered
number can be programmed to select one of 60 Call Distribution
It is also possible to program different Call Distribution Patterns for day
and night.
* DDI (Direct Dialling In)/MSN
(Multiple Subscriber Number):
One of ISDN services to
provide specific numbers to
each extension for direct
access from outside.
* CLIP (Calling Line
Identification Presentation):
Caller ID information; one of
ISDN services to display the
calling party's number on the
receiving telephone.
The system can distribute the incoming calls in a variety of ways. Effective
utilisation of various Call Distribution Patterns will improve the call
Regular Office Call Distribution
Depending on CLIP/DDI/MSN, it is possible to ring either only 1 extension or
several extensions.
• When only 1 extension is set to ring, its owner can forward the caller to
an appropriate message taker (the Personal or Company Message Box*)
to take messages.
• When more than 1 extension has been set to ring, it is possible to set
different ringing timing for each extension (Delayed Ringing).
* Voice Message Card is
required. (KX-TD61291)

Group Call Distribution
* A maximum of 32 Hunting
Groups can be established in
the system.
* Voice Message Card is
required. (KX-TD61291)
The incoming calls can be distributed to appropriate groups of extensions. To
realise this treatment, you can programme the system to direct these callers to
a specific hunting group*1. It is also possible to assign a backup extension to
the group for the caller to overflow, if not answered within a specified period of
time. The backup destination can also be a Campany Message Box*2.
Fig. 8-1 Group C all Distribution
With the Group Call Distribution, the following hunting patterns are available:
Simultaneous Ring
When a call comes in to a Simultaneous Ring group, all available extensions in
the group will ring simultaneously. It is possible to answer the call from any
extension within the group.
Fig. 8-2 Sim ultaneous Ring
Circular Hunting
In a Circular Hunting group, the extensions are searched in a fixed order until an
idle extension is found.
Fig. 8-3 Circular H unting
Call Distribution
Uniform Call Distribution (UCD)
In a UCD group, the calls are distributed equally among all extensions in a
circular fashion. Because no one will be taking more calls than another, you can
effectively even out the workloads among the extension users and hence
improve the overall call management efficiency.

Queuing Messages and Music on Hold
When the call traffic and there is no idle extension within a receiving hunting
group (Simultaneous Ring, UCD, or No Reply Group), the Queuing Function will
then put the callers on hold with messages* and music until they are answered.
Effective use of this feature will improve the image of your company as well as
help you avoid losing business opportunities. The Call Treatment Table
determines the queuing procedure, and in which the following commands can
be flexibly combined:
* Voice Message Card is
required. (KX-TD61291)
• Playing a Greeting Message* (9 Messages Recordable).
• Playing the Music on Hold or Ringback Tone (the length is selectable
from 16, 32, 48 or 64 seconds).
• Return to the first or second step of the Time Table.
• Transferring to the Backup Destination
• Disconnecting the Call
• Maximum of 4 Call Treatment Tables can be registered, each consisting of
up to 5 steps.

if not answered, the Boss’ telephone will ring (Delayed Ringing).
• The Secretary can call the Boss even when the Boss is in Do Not Disturb
(DND) mode (DND Override).
• The Secretary can make calls using Boss’ Toll Restriction Override
Account Code on behalf of the Boss. The call accounting record will show
that the Secretary has made the call using Boss’ account code.
Busy on Busy
If the number of busy extensions in a hunting group has become greater than
or equal to the pre-assigned number, it is possible to send a busy tone to the
next caller. This feature can limit the number of people who attend calls to a
specific number, in order to let others to perform different duties. For example,
in a office of three, you can make the system to allow only two people operating
on the telephone at the same time, so that the remaining person will stay
available for other tasks.
The line is busy.
