DIS-ТОР should be connected to DCN-2 Central exchange to perform the functions.
DCN-2 performs the functions for control of data flow routing, configuration of DIS-TOP
controls, individual numbers for subscribers indicated on direct keys, assignment of
connections priority and its functionality.
The following local functions that involve volume control of the built-in loudspeaker
or headset, headset activation are assigned to DIS-ТОР direct keys by DCN-2, however, these
functions are executed without central exchange.
Under the control of DCN-2, DIS-ТОР provides:
−simplex loudspeaker communication with a built-in speaker, a microphone on a flexible
“gooseneck” stand and function keys of direct call (FK);
−Simplex and duplex communication with loud-speaking function for subscribers
through built-in loudspeaker, microphone installed at flexible goose-neck using direct
keys;
−Simplex and duplex communication of subscribers using the headset;
−Establishing communication with subscribers by pre-programmed direct keys,
memorizing and call repeating of the last call
−Display of DIS-TOP number, date, time and type of communication for incoming and
outgoing calls, as well as numbers of calling and called subscribers;
−Indication of incoming and outgoing calls, type of communication, busy subscribers,
unanswered and last calls; four-color backlighting of direct keys, additional LED
indication on the front panel and microphone;
−Volume control of built-in loudspeaker, headset loudspeaker and call signal with the
help of pre-programmed keys of local functions “volume up”, “volume down” within
the audio range from -36dB (audibility is available) up to +12dB with the step
1.5dB;Extending the total amount of direct keys up to 168 including connection of EC-
TOP RMLT.468366.001 expansion units (available only within external power
supply -48V).
Configuration of DIS-TOP is executed from Administrator’s PC based on DCN-2
where the specific software “software applications for DCN-2 RMLT.00008-01” being
installed. DIS-TOP functions being performed under the control of DCN-2 are considered as
analogue functions of DIS call station. The functions description is provided in detail in “DCN
communication system. User manual. Part 2. Administrator manual” RMLT.465275.002.

The main controller of the board is comprised of two ATMEGA128A-AU
microcontrollers with a 10-bit ADC and 128 Kbytes of programmable memory. When the
power and interface are connected, the main board ensures DIS-TOP functioning with
respect to the algorithm allotted by DCN-2 central exchange. The main board of DIS-TOP
has sockets; some of them are lead out to the base of the enclosure for connection with Uko
network interface, headset and handset and with EC-TOP (see Figure 6):
- Х1 – socket for headset connection;
- Х2 – socket for speaker connection;
- Х3 – socket for microphone connection;
- Х6, Х7 – sockets for communication cables with EC-TOP expansion units;
- Х4 – socket for connection of power supply and Uko interface cables.
On the board there are LEDs backlighting for the desktop keys including contact
pads for each key, the closing of which, when you press the keys, leads to the execution of
a specific function assigned to DIS-TOP key.
The call station has 42 keys with LED backlight indication, 7 keys in a line slot, the
number of slots is 6. To provide specified protection degree for DIS-TOP, the keys are
furnished with silicon membrane. Each key is assigned for establishing connection with
subscribers or performing local functions as follows: “Headset”, changing modes for “Public
address” and “Headset” via DCN-2.
Each key consists of a transparent cap, a pusher and a base. The contact pads on the
main board will be conductive-closed when pressing a key. Two programmed modes for
processing of keypress are available. The first mode of processing is identified as contact
closure, keys release is identified as contact break.
In other cases, the close-in is registered when the key is released, with that repetitive
keypress is processed as breaking. The modes for processing of key presses are programmed
via DCN-2.
The transparent cap of each key is illuminated by LED backlights located underneath
the keys at the main board. With respect to programmed function of the key, different colors
of backlights are available as follows: red, green, blue, orange.
The LED indication modes for DIS-TOP various programmed functions is provided
in 4.3.

The keys are high-strength and wear-resistant.
The direct keys have no key labels, the transparent film incorporating into DIS-TOP
scope of supply can be applied for function identification of DCN. The functional labels are
printed out with allowance for film/paper thickness up to 100 microns and placed
underneath transparent caps of DCN. The paper of A4 size can be applied for printing out
labels. Key label Template is shown in Appendix D.
here is a slot on the key side for the convenience of function signs placing (see
Figure 7). It is necessary to open the cap of the key, then insert a paper element with the
printed designation of the function prepared in accordance with the template (Appendix D)
inside the cap and latch the cap back.

1.2.3 Microphone
DIS-TOP uses a removable high-sensitivity G14-2 condenser microphone on a flexible
gooseneck (see Figure 8). The microphone has a red LED that indicates the type of incoming
or outgoing communication by a constant glow or blinking (Appendix C). The microphone has
a unilateral direction that minimizes the effect of third-party interference, and a wide range of
perceived frequencies from 100 Hz to 10 kHz.
The microphone is installed and removed through a three-pin screw socket.
Optionally a shortened version of G14-3 microphone of 41 mm high can be supplied
without LED indication (see Figure 9). Both microphones are equipped with wind shield that
makes the sound clearer (keep out noise, whistles and other similar distortions).

DIS-TOP uses a wideband 2,5 Inch broadband speaker with plastic membrane, main
specifications are as follows: rated resistance 8 Ohm, frequency range from 200 to 15kHz is used
in DIS-TOP.
1.2.5 Display
To display additional information and for user convenience, DIS-TOP uses TFT
graphic display with LED backlights, with 4.3” diagonal, the resolution of 480*272 pixels that
ensures clear visibility of displayed data. The anti-reflective coating improves perceiving of
information displayed, it is applicable for bright lighting conditions as well.
