1.1 Instructions
1.1.1 Instructions for using the PABX system
Unauthorized opening of the PABX and improper repairs may result in risk of
injury for the user.
Caution! Unplugthe230VAC connectorplug beforeremoving the
enclosurecoverandworking onthecable terminalbay.
Replace the enclosure cover before plugging the 230
VACconnectorplugbackin.
Do not expose the inside of the PABX to any liquids; this can result in electric
shock and can destroy the PABX.
You should not connect or disconnect any lines to/from the PABX during
thunderstorms.
Description
Only terminals with SELV and/or which comply with ETS 300047 may be
connected to the PABX system. The normal use of authorized terminals fulfills
this regulation.
1.1.2 Loss of Power
On loss of power (230V~power supply) the PABX is not operational, meaning
that you can make neither inhouse nor external calls. An ISDN terminal with
emergency power capabilities can be operated via the additional emergency
power module (NSP module).
On return of power, functions which have been configured by the user, e.g.
internal and external connections, are not active.
The features configured using setup programming are unaffected by a loss of
power.

1.2 PABX Description
ThePABXisanISDNtelecommunicationssystem(PABX)forinterfacingwith
the Euro ISDN (DSSI). The PABX is provided with external ISDN connections,
which are configured for interfacing to the ISDN connections of the network
service provider. Depending on the type of PABX, ISDN connections can be
setas requiredasinternalorasexternalISDNconnections,Inaddition, module
slots for expansion of the ISDN and a/b ports are also provided. You can
program the type of connection for the external ISDN connection either as a
multipoint connection, or as a point-to-point connection. Depending on the
type of PABX, up to eight (8) analog terminals can be connected. It is also
possibletouse doorphoneunits andimplementexternalmusic onhold.Internal
numbers (the destination for theextension number with point-to-point connection)between00 ... 99 can be freelyassigned.Thefeaturesprovidedfor analog
terminals can only be used with terminals which use DTMF calling and which
are equipped with a flash button. Analog terminals which use pulse calling can
only use features which operate without the flash button being pushed. Please
note that the pushbuttons for some of the ISDN terminals available on the
market may limit the use of the features provided by the PABX system.
All terminals connected to the PABX must be certified.
1.2.1 Cleaning
Please observe the following points:
You can clean your PABX system without any problems. Use a slightly
moistened cloth or an anti-static cloth for this. Do not use any solvents! Never
use a dry cloth; electrostatic charges could result in faults or malfunctions in
the electronics. Alwaysensure, however, that nomoisture penetrates intoyour
PABX,asthiscouldresultisdamagetothePABX.

2 Installation
2.1 Installation of the PABX
Please check to ensure that all items are in the package before beginning
installation.
Contents:
• 1PABX
• 1ISDNconnectioncord
• 1PCconnectioncable9/9-pin (RS232)
• 1Setof operating instructions
• 1CD-ROM for setup programming under
Windows3.1,Windows95andWindowsNT
• Bagwith connector terminals
• 1Drilling template
• 3Dowels
• 3screws
2.1.1 Installation location
Your PABX has been designed for operation at ambient temperatures above
0 and below +40 °C.
Therefore, we recommend that you avoid installing your PABX in the following
locations:
• above or in frontof sources ofexcessive heat,e.g.radiators
Installation
• inplaces exposedtodirectsolar radiation
• behindcurtains
• insmall, non-ventilated rooms
• inrooms with excessive humidity
• onornearflammable
materials
• in the vicinityof high-frequency devices, such asradio trans-
mitters,radiotherapy systems, etc.
The PABX is powered via a 230 V AC utility outlet. Please ensure that the
electrical outlet (grounding outlet) for the PABX (and for additional devices
13
Installation
where required) is installed such that it is freelyaccessible atall times and that
it is installed by a qualified electrician to prevent personal and material risks.
We recommend installing separate supply circuit for 230 V AC power to your
PABX.ThisprotectsyourPABXfromshort-circuitsthatmayoccurinother
inhouse equipment.
Also install functional grounding. For this, connect the grounding terminal FE
to ”Ground”. Metallically bright partsof water orheating linescan beused here
as ”ground”. Ensure that these lines are continuously conductive and that they
are connected to the grounding circuit connector of your house service
connection.
We recommend installing our fine overload protection module (FSM) for overvoltage protection of your PABX which can sometimes occur during thunderstorms.
The distance from the PABX system and the 230 VAC outlet and the ISDN
connection should not be more than 1.3 meters due to the length of the
connecting lines.
2.1.2 Wall-mounting the PABX
•
•
DonotinstallyourPABX during a thunderstorm.
• Place the drilling template on the selected mounting location
andensure thatitisperfectlyperpendicular.
• Markthe drilling points on thewall using thedrilling template.
• Ensurethatall thecontactsurfaceshavefirmcontactwiththe
wall and that there are no concealed supply cables or other
wiringatthe drilling points you haveselected.
• Drill the mounting holes at the marked positions (when using
dowels,use a 6 mm masonry drill).
• Screwthe screwssuppliedw ith thesystemintothe wallsuch
that there is a gap of about 5 mm between the head of the
screwand the wall.
• Hang the PABX on the screws by inserting the screw heads
intotherearpanelmounting holes.
• Then secure the PABX by screwing in the third screw at the
markedposition.
• Install the function ground.
14
2.1.3 Intelligent Power Management for the
elmeg C48m and elmeg C88m
Your PABX is equipped with the Intelligent Power Management system. This
system protects the ISDN connections of the PABX against overload. The
current load is continuously monitored at each internal ISDN connection.
If too manyterminalsare connected tothe PABX, thisis indicated by aflashing
green LED (elmeg C48m and elmeg C88m). Power supply to the mounted
modules is also switched off. The PABX then attempts to reactivate the power
supply automatically after a set time. If, for some reason, the cause for the
overload is not eliminated (e.g. removal of a terminal), the ISDN connection
concernedisdeactivated.ThedeactivatedISDNconnectionisre-activatedonly
on a reset of the PABX and after elimination of the overload. Please contact
your dealer if the same ISDN connection continues to be deactivated.

2.2 Connections
Before installing your PABX at an ISDN connection, you must first decide what
type of connection (multipoint or point-to-point) you wish to configure as your
ISDN connection. This connection mustbe applied for at your network s ervice
providerand thenconfiguredin the PABX as describedinthesectionProgramming.
2.2.1 Terminals
The terminals can be removed from the soldered pins on the printed circuit
board (pcb). This allows you, for example, to switch user connections without
disconnecting the cables. In the as-delivered state of the PABX, the terminals
arenotconnected;theyareincludedinaseparatebag. Todisconnectterminals
which are set, lift the terminal block up carefully using a small screw driver and
then remove the terminal. Ensure that you do not bend the pins.

2.2.8 Internal/external ISDN connection 1
elmeg C46e:
Can be used only as an internal ISDN connection.
When the NSP (emergency power supply) module is used, it is imperative on
the elmeg C48 m and the elmeg C88m that this connection be used as an
internal ISDN connection.
Figure 11 illustrates the connection circuit for the internal ISDN connection 1.
This connection is provided with interfacing to an ISDN jack for the internal
ISDNconnectionandfixedinterfacingtothe terminalsfor theinternalor external
ISDN connection.
Installation
First remove the jumper for switchover for external connection (see Fig. 11)!
