BASIC STRUCTURE
In DS or IPV50 Series Systems DSS modules directly connect to the related NT digital
phone set. There is no need to specifically introduce the digital DSS modules to the system
so the terminal number setting is not required. DSS modules directly communicate with the
system over the digital NT phone.
The digital DSS module consists of 24programmable keys in 12x2 matrix structure. There
is a paper on DSS3K-24 module to write assigned names, numbers or services. Also
DSS3L-24 module has an LCD screen which user can see the assigned names, numbers
or services.
UTILIZATION
There are some facilities for different situations in order to use the programmable keys on
DSS module.
It is enough to press the related DSS key if a service is wanted to be activated.
If an extension or line number is assigned to the key, the call is started just by pressing this
key. While in a conversation with a programmed number if this key is pressed, the call will
be parked. The call can be retrieved upon pressing the key again.
GENERAL APPEARANCE
LED STATUS
Each of 24 keys on DSS module can be programmed for two different functions and the
status of the first function is shown with a red LED. If the assigned service is active, the
related LED becomes ON. If feature is cancelled, related LED becomes OFF. In the normal
operation mode, you can trace the function status of the keys as given below:
Extension Status LED Status

PROGRAMMING
Since the programming of DSS keys are directly made through the connected NT digital
phone, there is no need to make any programming over the DSS module. All required
settings are made through the NT Series Telephone Sets. The DSS Settings menu of
telephone is used for this purpose.
Sub menus of DSS Settings are listed below:
• Key Programming
• Auto Settings
• Delete Key
• Delete All Keys
KEY PROGRAMMING
There are totally 24 programmable keys and the assignments of programs are made
through this menu. If the desired key is pressed for along time, the second function of the
key can be used for the programming, so totally 48 functions can be programmed to these
24 keys. Keys become active after programming is done. The functions that can be
assigned to keys are explained below.
Extension
User can reach an extension, which user call frequently, through a single key by
programming the extensions number on the key. After entering the extension number,
select the key you desired to program. An extension number can be assigned to more than
one key.
After the programming mode is exited and this key is pressed, the extension that has been
stored on the key can be directly called. In addition to the calling function, status of the
extension, which was programmed as the first function of a programmable key, can be
viewed by the LED of the key and also can be viewed on LCD screen of DSS3L-24
module.
Line
It enables you to program a specific line number on a key. By pressing that key, you can
access the line that has been programmed on the key and make a call (provided that it is
vacant) and you can access that number by a single key.
A line can be assigned to more than one key. After the programming mode has been
exited, upon pressing those keys, it is possible to access the programmed lines, without
pressing 9. The status of the line (that was programmed as the first function of a key) can
be viewed by the LED of the key and also can be viewed on LCD screen of the DSS3L-24
module.
Call Control Key
This key is designed for users who have high intense call traffic, to park and hold calls by
pressing a single key only. Any line (internal or external) which is not assigned to any key
of DSS module, will be assigned to the first empty call use key. User can easily park and
retrieve this call easily by pressing that key.
First of all, number of Call Control Keys -between 1 and 6- should be decided. (If the ‘0’ is
selected, the Call Control keys defined before will be canceled.) After that, DSS number of
the keys should be defined. (For example; when there are more than one DSS modules, if
the keys wanted to be programmed as ‘Call Control Key’ are on the second DSS module,
‘2’ must be written to ‘DSS Number:’ field.) After the process is confirmed, desired number
of call use keys will be assigned to the related DSS module by starting from the last key of
DSS module. (The last key on the related DSS module will be the first Call Control Key.)
Thanks to this, six different calls can be controlled at the same time. Calls will be assigned
to the call control keys in sequence (starting from the first one).
If there are no call assignment to those keys, there should appear ‘ - ‘ at near of the related
key on the DSS3L-24 module. However if there is an assignment, there should appear the
related number at near of the key. The status of a call can be viewed by the LED on the
key and also can be viewed on LCD screen of DSS3L-24 module. LCD Messages and
their meanings are shown below:
Status LED LCD
Incoming Call
Blinking with a Special Cadence
“Line / Extension number “
Busy
Continuously On
“Line / Extension number”
Parked
Blinking Fast
“Line / Extension number P”
Phonebook
Any of the numbers in the phonebook can be assigned to any of the programmable keys.
Feature
It enables user to use provided features by a single key.
Provided features are listed below:
• Call Diversion
• Change tag
• Do not disturb
• Night mode
• Call pick up
• Call back
• Phone lock
One of the features in the list is selected by using left and right navigation keys. Then, on
‘DSS Key:’ field, user should press the key for a short time to select the first function or a
long time to select the second function of the key. The assignment will be confirmed by
pressing ‘OK’.
Call Diversion; If this key is pressed and number of an extension is entered, forwarding to
that extension is actualized and then red LED lights. If it is pressed again, the forwarding is
cancelled and the LED goes out.
Change Label; This key is used to display the second function of the keys on the LCD of
the DSS3L-24 module for a short time. (This key is not usable for DSS3K-24 module.)
Since the Change Label is a special key, it has only one function so user can not program
any feature for the other function of the key. While programming this key, if there is another
feature assigned before it will be deleted and new feature will be programmed.
Do Not Disturb; While the telephone is on hook, if this key is pressed it puts the extension
into the “Do Not Disturb” mode. In that case, telephone rings once when the extension is
called. If it is pressed again the “Do Not Disturb” service is cancelled. The corresponding
red LED is on while it is active, and goes out when it is cancelled.
Night Mode; The used mode (Day or Night) can be seen through the LED of the key. It
can be employed only through the telephone that has been defined as the operator. The
phone puts the system into the Night Mode when this key is pressed by the operator. The
red LED turns on if night mode is active. If the key is pressed by the operator again it puts
the system back into the Day Mode and the LED goes out.
Call Pick Up; When a user is busy or in a conversation, the incoming internal or external
call can be taken by pressing this key and at that time the first line is parked.
Call Back; If a called extension is busy or not answering and if busy tone is received upon
attempting to access a line, then that extension/line is called back by pressing this key and
the appropriate red LED lights. In order to cancel the call back operation, the key is
pressed again while the telephone is on hook and the LED goes out.
Phone Lock; If this key is pressed and a password is entered, the telephone will be closed
for external calls. The telephone will be opened for external calls again, if the procedure is
repeated. The corresponding red LED is on while the telephone is locked and goes out
when it is unlocked.
