Note:
J18 – the connector is intended for connecting the PBX with a PC. It thus allows
the programming of the PBX using the program OMEGA Lite - PROGRAM, detailed
display of operation using program OMEGA Lite - PANEL, for connection of XAPI
Server, etc.
The serial port includes an insulating DC/DC converter of its own and, by
optical signal transmission, provides galvanic isolation of the serial port from the
PBX with a guaranteed insulation strength of 500 V.
This solution has the following advantages:
• Helps transmit data over long distances
• Improves data transmission reliability (resistance to disruption)
• Enables communication with a PC powered from a different power supply section
(for example, from a different phase or central UPS)
• Improves overvoltage resistance of the input
For connection with a PC, especially over a greater distance, a normal (i.e., cross-
over) four-wire telephone cord with RJ-12 terminals is normally used instead of a
special “serial cable”.

3.2. Power supply
As the Power supply a power supply module with open construction and with
output voltage of +24VDC/2.7A (connector J2) is used. One integral part of the
supply is the cooler, which is designed for an upright working position of the PBX. It
is not allowed to operate the PBX in a horizontal position (lying on a table etc). The
source is distinguished in particular by the simplicity of connection, which is a
guarantee of the source’s maximum reliability. The source has an overvoltage fuse
(F1) F4A/250V. The power goes to connector J1.
3.3. Source – mains part _ ringing transformer
The mains part is attached using a detachable mains lead (so-called EURO
socket).

The lever switch located on the right side of the chassis serves for switching
the power on and off.
The mains part is protected against contact with live parts by a cover which
also covers the actual power source.
The ringing voltage with a frequency of 50 Hz comes directly from the mains by
a so-called ringing transformer. The ringing transformer is protected from shorting by
fuse T0.063A.
WARNING! This part is connected to the mains power and works with voltage which
is dangerous to life. All repairs and replacements of these
parts are only made at the manufacturer!! Only the
following handling is allowed:
WARNING!
Disconnect from
mains before handling!
• Mains lead connection and disconnection
Always perform this handling with the PBX disconnected
from the mains!!!
!!! Note: The source can be connected to equipment of the type UPS ( backup
source).

General features
A line module generally contains two interfaces. One exception is the module S0,
which contains one interface (but which carries two calls at the same time) and combined
module of external and internal line. Modules are equipped with overvoltage protection
and can be fitted to the motherboard or extender module in any order. All modules are
equipped with an identification system allowing the program of the PBX to ascertain the
concrete configuration immediately after switching on. All module connectors contain two
pairs of blanked holes (without contacts). This measure prevents the incorrect insertion of
modules.
All modules can be fitted up to the maximum number of vacant positions (12 = 6
motherboard + 6 extender module).
RJ45 connectors for connecting local circuits are a part of line modules. The
module is secured against movement by a screw in the connected strip.

The GSM module makes it possible to:
• automatically make calls to the GSM network and thus significant reduction in
telephone bill of your firm.
• receive incoming calls and, in connection with the DISA code distribute them to the
branches (analogue internal lines, system lines).
• When calls are made to the GSM network, to utilise all the services of the PBX
(reconnecting call, conference, rerouting, CLIP-called number display and its
entry on record).
In the current form the module does not make it possible to:
• convert a fax GSM connection to an analogue fax connected to the PBX,
• convert a data GSM connection to an analogue modem connected to the PBX.

5.8. Module ISDN S0 (Order No 1880020)
The module contains two four-wire interfaces BRI or 2B+D (1x ISDN input, 1x
ISDN BUS), and so two calls can pass through it simultaneously. It is intended for
connecting to the public ISDN network and supports connection in the regime PTP
and PTMP.
• In the regime PTP (Point to Point) the code DDI is supported (i.e., as many
sequential numbers as the user requests of the ISDN provider). It is not possible
to attach any further ISDN equipment to the line. The advantage is the possibility
of merging capacity – when several ISDN modules are fitted they can all have the
same code.
• In the regime PTMP (Point to MultiPoint) MSN is supported (i.e., upon request it
is possible to allocate up to eight numbers, but it need not be a continuous series
of numbers). It is possible to connect further ISDN equipment to the line (for
example, ISDN card in computer – one number, on the module up to seven
numbers will remain).
We recommend that overvoltage protection be installed to prevent destruction of
the ISDN module by overvoltage.
The control program of the module is stored in a FLASH memory which enables
the updating of the program directly in the PBX.
One of the input RJ45 connectors can be used for simpler creation of an ISDN
bus and thus for the connection of further ISDN equipment (ISDN telephone, fax,
modem).

Detailed installation
6.1. Selection of place for PBX
Aspects which must be taken into consideration when selecting a place for the PBX:
• Good visibility and accessibility (the exact time and other data about operation is
shown in the display of the PBX in operation).
• Protection from damp and extreme temperatures: the PBX must definitely
not be located near heat sources (above heaters) or in a place where direct
sunlight may fall. Also avoid damp places (bathroom, cellar), places where
the temperature changes rapidly (near doors, windows, air-conditioning),
dusty places (workshops etc) or places with aggressive gases (battery
rooms, boiler rooms) and places with high vibrations and shocks
(compressors, heavy industrial operations). The PBX has an upright
operating position.
• Installing circuits in building: by choosing a suitable location for the PBX (centre
of building or administrative centre) it is possible to reduce the costs for the
building of the circuits. If there are already circuits in the building, the location of
the PBX is generally already determined thereby and it cannot be changed.
• Possibility of direct connection using modules with connectors RJ-45.
• Quality of GSM signal: if one part of your configuration is (or later will be) a GSM
module, it is necessary to take into account the fact that the cable from the PBX
to the GSM cable is usually about 3 metres long (maximum 10m). It is therefore
necessary to make sure that in the specified circuit around the selected place for
the PBX there is a place with a good level of GSM signal suitable for locating the
GSM antenna. *)
• Ensuring against theft: when selecting a position, it is recommended that the
conditions of the insurance company be respected.
• Opening cover: there should be at least 10 cm of free space right and left of the PBX.

Note: In places with a poor level of GSM signal it is possible to use an independent
(external) GSM gateway which can be installed at a distance of up to 500 m from the PBX (!)
in a place with a good GSM signal (on high building, hill etc.) and ensure both cheap access
to the GSM network and reliable function in places where there is very poor coverage
(borderline areas).
6.2. Unpacking and checking
If you haven’t yet done so, check that the delivery is complete. The packaging of
the basic module is usually used for the transport of other independently purchased
items of the PBX (modules etc.). You can usually check them using the delivery note
and order numbers which are on all parts. The remaining components in the upper
part of the box are the accessories of the basic module. Remove the separate basic
module from the upper part. Open it and check everything against the packing sheet,
which is a separate annex to the documentation. Check whether there was any
mechanical damage to the parts during shipping. On the top of the box there is a
printed reinforcing piece which serves as a drilling template for the mounting of the
PBX. Keep the packaging (especially from the extender modules).
6.3. Installation of extender module
First connect an extender module (extender) using connector J1 with the
motherboard (connector J1) and then affix it to the chassis of the basic module
using six screws.

Note: All modules can be fitted separately even after the PBX is mounted on the wall, but it
is more comfortable to fit them on a table.
Line modules can be fitted in any position on the motherboard (connectors
J2-J7) or extender module (connectors J2-J7).

7. Mounting PBX on wall
Using the drilling template (on scale 1:1), mark two holes on the wall (for
requirements for location see above, paragraph Selection of location for PBX). Using
an 8 mm masonry bit, drill holes and put rawlplugs in them. Screw the hanging
element of the PBX into the upper holes using two screws (it is fixed to the chassis
on delivery). Hang the PBX and secure it against being knocked off by screwing the
(screw M3) chassis to the hanging element. Finally add the cover.
7.1. Earthing PBX
As has already been stated, good earthing of the PBX chassis is very important
for the good functioning of the overvoltage protectors on the line modules. The PBX
is naturally also earthed through the mains network (as a result of the earth wire – if
it is connected to the plug). But this is not enough – for one thing in view of the
danger that the PBX could be easily disconnected from the mains (the overvoltage
from any line would then easily spread toe the chassis of the PBX and from there to
all other lines!), and the principle applies that earthing should be as good as
possible. The ideal solution is thus a yellow-green copper wire with a cross section
of at least 4 mm2, leading for example from an earthing strip in the main switchbox.
In an emergency it is necessary to at least earth it using such a wire (i.e., not
Installation manual 43
www.2n.cz
2N

Installation manual
disconnectable) from the nearest power socket (and check that it is correctly
connected). Attach the wire to the chassis on the earth clamp on the right side of the
chassis (marked with the earth symbol) and tighten well. We recommend that the
earth always be connected before other cabling!!!
7.2. Connection to mains network
The detachable EURO-lead serves for connection to a regular socket. This
makes it possible, if necessary, to rather elegantly make the lead longer with an
extension EURO lead (used, for example, for connecting a PC and monitor). This
extension also fits into the installation strip, for example 4x4 cm with other cables.
The power lead can be run from the PBX through the hole in the power platelet with
a hole and leads to the socket freely or through the strip.
7.3. Cabling for connecting system telephones
Every system telephone is connected to the PBX by a four-wire cable. The wires
are marked A, B (call) and C, D (power + data both ways). For a system telephone to
work, it is necessary not to swap the individual wires! If correct telephone cable is
used (four-wire cross cable), this condition is met.
(you can tell if a cable is crossed by putting both transparent terminals next to each other
pointing in the same direction, the coloured wire in both terminals are in the opposite order)
If this connection does not work, the connectors probably do not have identical
connection of terminals.
7.4. Cabling for connecting ISDN
According to the standard, the subscriber termination of line ISDN (NT1, NTBA
(Network Termination Basic Access) is fitted with a connector RJ-45 with eight
contacts. The module ISDN in the PBX is also equipped with the connector RJ-45,
which can be used if the distance is not greater than 3 m. In this case it is necessary
to use four-wire non-crossed cable with terminals RJ-45.
(you can tell if a cable is not crossed by putting both transparent terminals next to each
other pointing in the same direction, the coloured wire in both terminals are in the same
order)
If this connection does not work, the connectors probably do not have identical
connection of terminals.

8. Minor servicing tasks
8.1. Replacement of lithium battery
The battery must be replaced if its voltage drops below 2.5 V. But we
recommend that the battery be replaced at least once every three years, even if its
voltage is correct. We recommend that the battery be replaced with the PBX switched
off. Before changing the battery, we recommend saving the program of the PBX and the
accounting data to a PC. After changing the battery, check the date, time and programme
of the PBX, and if this data is not correct, perform a correction of the setting. In this case
we recommend that this task be performed only when no one is using the telephone.
WARNING! Use only a tool made from insulating material for replacement!
WARNING!
Danger of explosion in case of incorrect battery replacement. It is only
possible to replace a battery using one of the same or equivalent type
according to the manufacturers recommendation. Always handle used batteries
according to the manufacturer’s instructions.
8.2. Setting music volume
On the motherboard there is a regulator for the volume of the external music source
(connector J25). This task can be performed with the PBX switched on. In view of the
miniature dimensions of the components, it is necessary to use a suitable tool (for
example, precision screwdriver) and the appropriately light force.

9. Expanding PBX
The PBX can be expanded as desired by buying further modules up to the
maximum configuration (24 lines). But it is necessary to be aware that every
expansion constitutes intervention in the installation, and if done inexpertly it could
threaten the functioning of the whole. In other words, the same level of knowledge as
for the complete installation is required for this activity.
There exist two possible methods:
1. Complete reinstallation of PBX – the advantage is the clarity of the procedure
and optimum result, the disadvantage is the amount of work involved.
2. Addition of new modules without intervention in original part. The result is not
always optimal, but there is less work. It is once again necessary to proceed
according to the same rules which apply for the installation of a new PBX.
When expanding the PBX by either of the above methods, it is necessary to
adhere to this procedure:
1. Before starting work, make backup copies of the PBX programming and
accounting data.
2. Before starting work, check that all lines work.
3. Respect the warranty conditions.
4. Use only new or tested modules.
5. First of all decide on the location of modules on paper.
6. Mount all modules.
7. Add cabling.
8. After the actual installation, retest the function of all lines – new and original.
9. It is always necessary to programme the new configuration again.
10. Test all functions which you have programmed.
11. Make another backup copy of the PBX programming.
12. Document all changes made.
10. Installation of front-end protection
If you have decided to install front-end overvoltage protection, we recommend
that:
• You carefully consider which lines you will protect (air lines, external lines or all
lines).
• You use protection which has signficantly better properties, for example.:
- 2N
- 2N
• Locate front-end protection at the entry of the wiring to the building. You will thus
gain the greatest effectiveness and you will also limit the possibility of induction
overvoltage in other circuits in the building.
• Under extreme conditions use protection which can be replaced easily (range 2N
