Installation and Configuration I-5
PTMP Connection ContentsAssemblyPTP ConnectionAppendix Programming
Dear Customer,
Thank you for choosing an Auerswald PBX. Would you liketo install your PBX yourself? This
won't be any problem at all, provided you read carefully the chapter entitled Chapter Con-
nection and Assembly on page I-9 and Chapter Connecting to the ISDN and Carrying Out
Initial Commissioning on page I-23 all the way through and follow the instructions step by
step. In no time at all, you'll be making phone calls from your new PBX.
When you have worked through Chapter PTMP Connection on page I-24 or Chapter PTP
Connection on page I-31, your PBX is already configured such that the individual telephones
only ring with the entered and subsequently assigned calling numbers. In conjunction with
the default settings that are available (refer to Chapter Default Settings on page I-79), the
statusof your systemis such thatyou can make phone callsas well as being able to usethe
door and other additional functions.
With the aid of Chapter Programming on page I-40, you can now set up an even more cus-
tomized configuration by telephone. You can, for example, make special settings for differ-
ent equipment like fax machines and modems as well as saving frequently used calling
numbers in the abbreviated dialling memory.
The supplied user software (refer to Chapter CD or Floppy Disk Containing User Program
for Windows on page I-81) provides you with further custom settings. If you do not want to
use these settings, you do not necessarily have to connect a PC. However, it is advisable to
use an available computer for programming the PBX, since the wide range of functions that
are available in the PBX would make programming using the telephone a very time-consum-
ing process.
This is how to get up and running particularly quickly:
햲Connect the available telephones to your PBX (refer to Page I-12 and Page I-14) and
enter internal extensions 41-48 as the MSNs in the available ISDN telephones (refer to
the telephone's operating instructions/do not assign the numbers twice).
햳Connect the PBX to the ISDN (refer to Page I-25 for PTMP connection or Page I-32 for
PTP connection).
햴Apart from this, connect the PBX to the 230-V mains (refer to Page I-26 for PTMP con-
nection or Page I-32 for PTP connection).
햵With PTP connection only: On the external S0port, activate connection type PTP (refer
to I-34/first observe the information below!)
햶You can nowmake internal and externaltelephonecalls. When somebody calls you from
outside, the telephones ring that have internal calling numbers 31, 32, 41 and 42 if they
are present.
hFor you to be able to receive calls from outside following these quick commissioning
measures, your PBX must be in the as-delivered condition (if the system was already in
operation, reset it as described on Page I-26).
You have to note some differences that depend on which of the PBXes that are described
here you are using. Information regarding ISDN telephones, for example, refers only to
PBXes that have internal S0ports. For more details of this topic, refer to the overview of
features on the cover.

1 Connection and Assembly

I-10 Installation and Configuration
Assembly
With the european DSS1 (Euro-ISDN) protocol, you initially need one S0connection (or two
S0connections if you want to run an ETS-4308 I with a second external S0port).
Your PBX is designed for the following types of connection:
앫Basic access as a point-to-mulitpoint (PTMP) connection.
앫Basic access as a point-to-point (PTP) connection.
If you are not sure which type of connection you have (e.g. because you didn't apply for your
ISDN connection yourself), you should contact your service provider.
For connecting your ISDN equipment, your pro-
vider will install in your house or office one (or
two) NTs (network terminators for basic access.)
You will be able to recognize the NT by its green
or white rectangular housing and the two sockets
(what are known as the ISDN sockets), which
are generally located on the bottom end face of
the housing; there are, however, variations
depending on the country and the manufacturer.
Your PBX will only function correctly if the NT is
also running properly.
If you have a PTMP ISDN connection, you can
connect an additional S0bus with twelve more
ISDN sockets. On this bus, you can then connect up to eight pieces of ISDN equipment
including your PBX. However, if your PBX has an internal S0bus, it is more sensible to con-
nect any further pieces of ISDN equipment to this bus.
Use the supplied ISDN cable to connect the PBX to the NT.
It is a definite advantage if you operate your PBX directly next to your NT to prevent long
transfer routes between the two devices (the supplied ISDN connection cable is about one
meter long). If there is an S0bus on your NT, you can of course connect your PBX to one of
the ISDN sockets on it.
Apart from this, you need a power supply (an easily accessible 230-V mains socket close
to the installationlocation) for your PBX and for the NT (if it has a mains plug and your ISDN
is a PTMP one.)
Do not install your PBX on premises that are subject to high levels of humidity, that are at
risk from dirt or extreme temperatures. You should also avoid mechanical stress (e.g. vibra-
tions) and keep away from equipment that emit electromagnetic fields or respond in a sen-
sitive way to electromagnetic radiation (e.g. radio receivers, ham radio equipment, or
similar.)

Installation and Configuration I-11
Assembly
Before opening the housing, always ensure that the plug has been removed from the mains
socket. Do not touch the live conductors or the telephone connections: this can be
deadly!
The housing consists of a base plate and the top section. Both sections snap together
and you separate them as follows:
jUsing a screwdriver or a similar narrow tool that fits into the slot in the middle of the lid,
lever the cover off towards the housing as shown in the diagram.
This is how to mount your PBX on the wall:
jUse the four screws and pegs supplied with the PBX to fasten the base by means of
the fastening holes in the corners of the base plate. You should use the drilling template for
AUERSWALD PBXes to mark the positions of the holes.
Every ETS-4308 I is supplied with one S0E-4308 expansion module. Depending on which
slot you are using on your basic unit's PCB, you can implement one of the following: an inter-
nal S0port (internal module slot on the right) or a second external S0port (Amt 2 module
slot on the left.)
To carry out assembly, plug the S0E-4308 expansion module into the appropriately labelled
socket. When you do this, the component side must be on the side away from the trans-
1. 3 Opening and Assembling the Housing
eIMPORTANT: For safety reasons, you must not remove the PCB with mounted com-
ponents from the housing.
hTo make the connection, use the removable terminal strips and the female connec-
tors on the bottom edge of the PCB with mounted components.
The cutouts in the base plate are for routing in all the connecting cables. Take care to
ensure tension relief that may be necessary by using clips, binders or similar.

former (the large black cube-shaped component. It is not possible to plug in the module the
wrong way round by mistake. Always unplug the unit from the mains before carrying
out any assembly work.
The ETS-2204 I PBX has an internal S0port. You can add an internal S0port to the
ETS-4308 I PBX by plugging in the S0E-4308 expansion module. If you have a PBX with
internal port, you can connect up to eight pieces of ISDN equipment. All the equipment must
be approved Euro-ISDN (DSS1) devices. The feed voltage that the PBX
produces is about the same as
that of your ISDN basic ac-
cess. This means that you can
use up to four devices that do
not have their own power sup-
plies (e.g. most Euro-ISDN tel-
ephones) and therefore need
to be supplied by the PBX. As
with theNT of a PTMP connec-
tion, there are two Western
sockets available on the inter-
nal S0port that allow you to di-
rectly connect two ISDN de-
vices. Here, you can connect
an Auerswald ISDN-Multiplug
(optional special accessory)
for distribution. The diagram
shows an example of a con-
nection layout without an inter-
nal S0bus.

connecting the ISDN equipment, e.g. ISDN telephones and ISDN PC cards.
1. 4 Connecting the ISDN Telephones to the Internal S0Port
hTo guarantee proper functioning, the cables that you use must be a maximum of
10 meters long.

Installation and Configuration I-13
Assembly
This is how to connect your ISDN telephones:
Plug one end of the cable supplied with your telephone into the telephone's appropriate
socket and the other end of the cable into the one of the available RJ 45 sockets in your PBX
or into an ISDN socket on the S0bus that may be present.
Internal calling numbers 41 to 48 are available for the eight possible pieces of ISDN equip-
ment that you can connect. You must inform the individual devices (Euro-ISDN telephones,
ISDN fax machines, ISDN PC cards, etc.) of the calling number to which they have to
respondin each case. To do this, you must enter these calling numbers as MSNsin the tele-

tive device. Assign calling numbers 41 to 48 only once in each case.
You can lay an internal S0bus on your PBX to connect ISDN devices. The S0bus consists
of up to twelve ISDN sockets that are switched in-parallel. On the last connecting socket,
you must mount between the terminals one 100-⏲resistor each with a minimum rating of
0.25 W. At the other end, you switch this terminating resistor by means of jumpers or DIL
switches on the PBX's PCB (see the diagram below).

햴ISDN cable (maximum of 10 meters long) with two identical RJ 45 (Western) jacks on both ends for
connecting the ISDN equipment, e.g. ISDN telephones and ISDN PC cards.
hOn the basic unit, there are four screw terminals (b2, b1, a1 and a2) to which you can
connect an internal S0bus. For details of the options that are available in this context, refer
to the Chapter Laying an Internal S0 Bus on page I-13.

If your PBX is located in the middle of the S0bus, you can remove the jumpers for the ter-
minating resistors or change over the DIL switch. Instead, you must attach at both ends of
the bus – i.e. at the lastconnecting box in each case – two 100-액terminating resistors each
(see the diagram below).

You can connect the following equipment to the analog subscriber's stations on the PBX:
analog LD or DTMF telephones, mobile phones (DECT, cordless phones), fax machines,
modems, answering machines, etc.
You connect the telephones and other equipment using permanently installed connecting
boxes. This means that you should first lay the cables between the PBX's installation loca-
tion and the locations of the individual analog devices. For this, use only telephone cable,
e.g. 0.6-mm JYY for permanent installations. If you use cable of the specified diameter, the
lines between the PBX and the connecting boxes can be up to 800 meters long. To prevent
disturbances, lay the lines carefully and twist thepairs.You should also avoid running cables
parallel with other wiring for long distances; this applies in particular to power supply lines.
hThe internal S0output is short-circuit-protected.

Connect the connecting boxes to
extension terminal pairs TN 31 (a

respective terminal label is
printed on the PCB in front of the
terminal. You can pull the termi-
nal blocks off the PCB to make
it easier to connect the connect-
ing boxesto the PBX. Ensure that
you do not plug in the wrong ter-
minal block or that you plug in the
correct one the wrong way round.

connecting jack into the socket on the connecting box.
You can connect a door terminal to your PBX. This allows you to use the doorbell, intercom
and door opening functions by means of the connected telephones. With the TFS-2616
entranceintercomsystem,you haveavailable the intercom function. If you usethis entrance
intercom system, you make the connection on relay number 1 in accordance with the con-
nection plan below. The make contact (TS1 and TS2) is not needed for the TFS-2616. At
the switching instant, it takes its feed voltage directly from the PBX via contacts TOUT and
TGND.
hTo be able to carry out the commissioning steps described in this manual, you
should connect at least two telephones to the PBX. In this case, use extension terminals
TN 31 and TN 33.
Internal calling numbers 31, 32, etc. of the respective connected analog extensions
match the designations of the extension terminals.

Using the connection plan below, you can also
connect third-party entrance intercom modules
to the PBX. With these intercom modules,
voice transfer must be carried out using two-
wire technology (one signal line and one
ground line) in accordance with German Tele-
kom standard FTZ-123-D12-0. If your intercom
module works with four-wire technology (two
lines per direction) you must insert a converter
from two wires to four wires (e.g. a TSA-500.
You can now switch the power supply for the
intercom system using the make contact (TS1
and TS2) of relay number 2.

hOnly if you use the housing that fits the TFS-2616 is there a guarantee of optimum
adaptation of the entrance intercom system to the PBX. Installing the TFS-2616 in a differ-
ent housing can lead to feedback, whistling or low volume levels. This is because different
housing shapes and dimensions can drastically change the acoustic conditions for the
TFS-2616. The sound propagation inthe housing affects thevolumeleveland thefeedback
response.
eImportant: The maximum loading level of the door opener switching circuit is 50 V/1 A
(i.e. it is not suitable for connection to a 230-V mains system).

As delivered from the factory, the available relays are set to the door functions. In Chapter
Using the Switching Relay on page I-58 you will find out how to change this setting. The
tables below show all the options that your PBX provides for configuring the relays:

Relay number 1 provides a make contact (TS1, TS2); relay number 2 provides a make con-
tact (TO1, TO2) with reverse voltage divider (100 nF, 220 액); and relay number 3 provides
a make (NC, COM) and a break contact (NO, COM). The PBX does not supply a switching
voltage to the terminals, i.e. the connected devices must be supplied with an external volt-
age! In this connection, note that the relay contacts can be loaded with 50 V/1 A); this means
that they are not suitable for switching directly devices that run on mains voltage.
A switching voltage is available at con-
nection terminal TOUT that corresponds
to the switching status of relay 1, and it
can be used to switch or operate rela-
tively small devices. If relay number 1 is
switched on, an unstabilized voltage is
connected of between about 12 and 21 V
DC (measured against TGND) that may
be loaded with 50 mA! This voltage is fil-
tered but is not stable: this means that it
is significant for the connected device.
To prevent damage in your PBX, do not
overload the switching voltage. The dia-
gram below shows an example of a con-
nection layout:
햲For example: Master control unit of air conditioning system (controlled by remote switching relay 1).
햳For example: Master control unit of shop window lights (controlled by remote switching relay 2).
햴For example: Master control unit of data processing system (controlled by remote switching relay 3).
If you also want to be reached at locations where you can't hear your telephone or the door-
bell, (in your garden, for example), you can connect a seconddoorbell to the two ZWKL con-
tacts on the ETS-4308 I. To find out how the contacts have to be set up, refer to Chapter
Technical Data on page I-82. You cannot connect a conventional doorbell here.
As shown in the diagram below, you
can use a normally open contact
(switching contact of your alarm sys-
tem) to wire up the ETS-4308 I's
alarm input. The contact in question
must be potential-free. For more
information, refer to Chapter Techni-
cal Data on page I-82.

tem.

Your PBX has an RS-232-C, V.24serial port.Using this interface allows youto conveniently
program the system from an IBM or compatible PC. Apart from this, you can use the serial
port to output directly the list of calls and charges. Connecting a serial printer to the port
allows you to output a hard copy of these lists too.
If you want to connect a PC or a printer to your PBX's serial port but they are not close to
your telephone system, it is advisable to lay permanent connection lines. In the case of long
transfer distances (two meters and above), you should, if possible. use a twisted-pair
cable (e.g. LIYCY 2 x 0.3 mm). Apart from this you need a 9- or 25-pin SUB-D adapter to
make theconnection to the serial port (COM 1 to 4) on your computer or printer. A cable with
a 9-pinSUB-D socket is supplied with the PBX. Cables with 25-pin SUB-D sockets are avail-
able fro most compute stores.
You can make your own connecting cable by following these instructions:
If possible, use a three-core or a two-core screened cable (e.g. LIYCY 2 x 0.3 mm). Use the
woven screen of this line for the terminal labelled PC-GND and the two cores for RXD and
TXD. On the computer end, fit either a 9- or 25-pin socket to match the serial port that is
fitted on your PC! The diagram below illustrates the connection arrangement. Note particu-
larly the numbering of the socket connections and the placement of the jumpers.
