Introduction 7
Introduction
Dear customer!
In order to install your new PBX please contact an authorized dealer.
The case may only be opened by authorized personnel1
Installation work on the open case are only allowed to exe-
cute by authorized personnel1.
The COMmander Basic is a PBX that is designed for the connection to
the digital telecommunications network ISDN (Point-to-Point connec-
tion and/or Point-to-Multipoint connection). It enables the switching from
the public communication net to different internal devices. The so-called
terminals may be system telephones, ISDN devices as well as analog
devices.
The ISDN devices (e.g. ISDN telephones, ISDN PC-controllers) should
be certified Euro-ISDN devices in order to guarantee a proper function-
ality. The analog subscriber connections enable the connection of most
pulse dialling, dual-tone multifrequency dialling and also of CLIP com-
patible units (telephone, fax machine, answering machine, modems).
Devices with dual-tone multifrequency dialling must have a FLASH key
(also called signal key R).
The COMmander Basic has a modular design. Due to special modules
it can be extended step by step, if you are in need of more subscriber
connections and S0ports than are in the basic unit or if you like to oper-
ate your door terminal device from any internal telephone.
Thanks to functions like e.g. Short-Code Dialling, conference, splitting
and internal free of charge connections the COMmander Basic makes
the daily telephone communication simple, comfortable and time sav-
ing. Additional to the telephoning the COMmander Basic offers numer-
ous functions such as call charge recording.
In case of an extension with a COMmander 2TSM analog module the
connection to a door terminal device as well as different switching func-
tions will be available to you.
The COMmander Basic can be configured to your special personal
requirements with the configuration software COMset. Three further PC
programs allow to comfortable manage call charge data, Short-Code
Dialling, call allowances, wake-up calls, Music on Hold and the data for
the automatic Least Cost Routing.
The scope of functions described here is only completely usa-
ble with a professional installation and a correct configuration
of the PBX and the connected PC. We highly recommend to
consult your authorized dealer first.
Please ask your network operator about the availability of some ISDN
service attributes. Some of these functions may be available for an extra
fee.
There may be incompatibilities in combination with terminals and
devices of other vendors, that adversely influence the usability of func-
tions.
To fully utilize the scope of functions described here, the PBX system
must have the Software version 1.6A and the system telephone must
have the software version 2.0H or newer (you may receive information
about these versions via system telephone). If this is not the case,
please perform a firmware update of the respective device.

When handling with 230 volt supply voltage and with the units supplied
by this voltage the relevant electric safety regulations must absolutely
be observed.
Please pay attention to the following general safety advice by all
means:
왎All devices must be installed without current. (e.g. in case of main-
tenance work).
왎All devices may only be put into operation if they are properly built
into the case.
왎Units that operate with external voltage - especially with supply volt-
age - may only be opened if they were disconnected from the volt-
age source or from the mains first.
왎The mains cables of the electric devices and the connection cables
must regularly be checked for damages. If you discover damages,
the concerning cables must be replaced.
왎The use of tools near or on covered or open circuit lines and circuit
boards as well as on and in devices that are supplied with external
power - especially with mains voltage - must be avoided as long as
the supply voltage is not switched off and the device is not made
free of voltage by discharging existing capacitors. The charge
capacitor of the switching power supply unit can be charged for a
long time in case of a failure even after being switched off.
왎If you use construction elements, components, assembly groups,
connections and units, you must absolutely take care of the limita-
tion values for voltage, currency and power consumption indicated
in the technical data. Exceeding those limitation values (also short-
time) may cause extensive damages.
왎The units, unit assemblies or connections mentioned in this opera-
tion instructions may only be used as described. If you are not sure
how to use the merchandise, please ask a specialist.

Preparations, Installation of the Case 11
Preparations, Instal lation of the Case
When opening the case cover you are in need of the supplied special
tool. Push the special opener tool into the opening as shown in Pic. 1
and pull the handle a little bit to the front. Now open the case by pulling
the special opener tool to the top away from the case. The cover is
pulled to the top at the same time. Slide the cover (app. 15 cm) so that
you are able to take off the case vertically from the bottom casing with-
out obstacle.
ATTENTION: The case may be only opened by authorized
personnel1.
Please pay attention to the fact that the plug must always be pulled out
while opening the case. Touching the voltage leading conductor tracks
or the telephone connections may be danger to life. During operation
certain modules may produce dangerous ringer voltage.
The plastic cover above the power supply unit serves as a touching pro-
tection against dangerous voltage and must not be removed. The
charging electrolytic capacitor of the switching power supply unit may
be loaded for a long time after being switched off in case of a failure.
Open the Case
1. Authorized personnel: These are persons that are trained for this purpose (e.g.
certified electricians). They must have the necessary knowledge about the
work in areas with potentially hazardous voltage. They must also have the
knowledge about the latest electrical safety standards and requirements.

12 Separating the Case Components
The case consists of two components in addition to the cover: The slight
grey installation chassis and the blue module frame. In order to attach
the COMmander Basic onto the wall, you will have to separate both
case components first.
Remove the cross bar with the thumb of your first hand, as shown in
Pic. 2 and remove the module frame diagonal to the top away from the
installation chassis with the other hand.
Before separating both case components you have to discon-
nect the device from the 230 Volt power supply by all means.
Before you attach the installation chassis onto the wall you have to pre-
pare the future cable lead-through. Depending on which side you like to
lead the cables through, at the right or left side of the cable spacing, you
open the cable lead-through passings in the installation chassis (Pic. 3).
If the second cable lead-through passing is determined for the enclosed
V.24 case sleeve, open this cable lead-through passing, too.
Install the V.24 Case Connector
If you like to connect a PC and use the enclosed V.24 case connector,
push the plastic frame with the connector (cable and 10-pole plug to the
inside) into one of both cable lead-through passings. Depending on
which side you like to attach the connector, you may also remove the
screws and attach the connector the other way round.

Preparations, Installation of the Case 13
The installation material (screws and wall plugs) is part of the extent of
supply. The installation chassis can be used as a drilling template at the
same time.
Select Installation Location
Please pay attention to the following issues when selecting the installa-
tion location for the COMmander Basic:
왎The COMmander Basic may only be operated in closed and dry
rooms.
왎Above of the case must be a free space of at least 150 mm for
putting on or removing the case cover.
왎Near the installation location you are in need of an unobstructed
230 volt mains plug with protective earthing for the power supply.
Please make sure that the mains plug is properly connected
(according to electric safety regulations).
왎The COMmander Basic must be next to the NT in order to avoid
long transmission ways between both units (the enclosed ISDN
connection cables are app. 1 m long). If it is not possible, a fixed wir-
ing (S0bus) between both units will be necessary.
왎The surrounding temperature must be from 0°C up to + 40°C.
왎The devices may not be exposed to direct sun light.
왎The relative humidity may be between 10% and 75%.
왎No condensation may occur.
왎The unit must be protected against splashing water and excessive
dust.
왎Please avoid mechanical stress (e.g. vibrations) and the close
neighbourhood to devices that radiate electromagnetic fields or
interfere with these units (e.g. radios, HAM-radio installations,
mobile telephones, DECT base stations, etc.).
Mount the Installation Case on the Wall
왎Hold the installation case onto the place where is should be
mounted and mark the drill holes on the wall. There are three holes
available for wall mounting (Pic. 4).
왎Make sure that around the marks no hidden supply pipes or cables
are in the wall.
왎Drill the holes with a diameter of 6 mm.
왎Now mount the installation case with the screws and wall plugs on
the wall.
The COMmander Basic must be mounted vertically. Please
observe also that the advice „top“ (see arrow in Pic. 4) printed
on the installation case really is at the top.
Assembly of the Case Components
If the installation case is firmly mounted on the wall, the module frame
can be re-attached again. In order not to squeeze the cable of the case
plug, roll it up near the plug in the cable space. Hold the module frame
diagonal with the upper edge to the wall and hang it into the top of the
installation case (Pic. 5). Then close the bottom part of the module
frame onto the installation case until the locking clicks into place.

14 Change and add PBX Modules
The mainboard of the COMmander Basic has 4 universal module slots
(A to D, in the basic unit slots A and B are already in use) for the follow-
ing modules:
왎the COMmander 4S0module (in the basic unit in slot A).
왎the COMmander 8a/b module (in the basic unit in slot B).
Besides this there is a module slot E for:
왎the COMmander 2TSM analog module (analog- door-, switching-
and music module)
The following limitation values have to be respected when extending
with further modules:
왎A maximum of 4 external S0ports can be managed.
왎A maximum of 32 internal subscribers can be managed. Each con-
nected telephone, fax machine etc. counts as an internal sub-
scriber.
왎A maximum of 3 COMmander 8a/b modules (also a maximum of 24
analog subscribers) can be inserted. The 4th universal module slot
is used for the COMmander 4S0module.
Remove a Module
Press the lower controller locking lever a little bit downwards to the
cable space. At the same time remove the module vertically to the main-
board with the other hand (Pic. 6). Pay attention to the fact that you han-
dle the module on the edge and in line to the slot connector.
Plug a Module in
Insert the module between both controller locking levers and press it
down vertically to the mainboard until it clicks into position. (Pic. 7).
Please pay attention to the fact that you have made the necessary set-
tings on each module before you put the module in again. Especially for
the terminator resistors and the switching of the S0ports (internal/exter-
nal) on the COMmander 4S0module (chapter Description of the
COMmander 4S0 Module on page 17).
Disconnect the device from the 230 Volt power supply and wait
another 10 seconds before you plug a module in or remove it.
As some components are sensitive to electrostatic discharge, it is
important to discharge yourself properly before touching the
board by hand or with tools. Touch a properly grounded, metallic
object e.g. a radiator or the case of a PC.

16 Description of the Mainboard
The Case LED
In the cover of the case is a multicoloured LED integrated. This case
LED displays the status of the COMmander Basic to you. The following
displays may be shown:
Off: The COMmander Basic is switched off or separated from the mains
voltage.
Green: The COMmander Basic is ready for operation.
Red (orange): The COMmander Basic initializes itself (after having
started or after reset). Red changes to orange after a few seconds and
then to green. If the LED does not turn to green but is still red, there is
an error.
The Reset Button
In contrast to removing the 230 volt power plug, the supply voltage will
not be interrupted by pressing the reset key. All internal and external
connections, recalls and exchange line reservations will be deleted in
case of a reset. All configurations done by configuration program COM-
set or by telephone will remain valid. The same is valid for the call data
memory.
The Automatic PBX Software Update Button
Stay informed on the news in the PBX software of the
COMmander Basic (on our homepage on the Internet). The version
number of the software used in this PBX can be requested via a con-
nected system display SD-420 (special accessory) or via telephone
(chapter Request Firmware Version on page 58).
If the software is not up to date, you will have to make an automatic PBX
software after the installation and the configuration. During this
update the COMmander Basic will make independently a telephone
connection to one of the servers at Auerswald and the current software
will be transferred while the call data and configurations will remain pre-
served. Besides of the costs incurred for the necessary telephone con-
nection this update is free of charge. The COMmander Basic already
knows the telephone number of the server at Auerswald. If the tele-
phone number changes, you will be able to enter this change into the
configuration program COMset.
The update may be initialized via telephone by dialling a sequence of
digits (see chapter Perform an automatic PBX Firmware Update on
page 62 in the user manual) or by pressing a button if the case is still
open. You should only initialize this procedure, if the PBX is idle (that
means not during business activities) because all the calls will automat-
ically be interrupted by the PBX. The procedure will last 5 minutes.
In order to activate the update, press the update key until the LED that
is next to the key starts blinking slowly. The LED continues flashing dur-
ing the whole procedure.
If the automatic PBX software update was successful, the LED will start
blinking faster at the end of the procedure. (positive acknowledgement,
will last app. 60 seconds).
If it failed, the LED is switched on at the end of the procedure (negative
acknowledgement, will last ca. 60 seconds), and you will have to start
the update again (e.g. the connection was not possible).
If the procedure lasts less than 60 seconds and you get a positive
acknowledgement, the PBX software has already been up to date.
After a successful PBX software update existing LCR data
may be deleted.
Creating an internal Telephone Numbering Plan by
pressing a Button
The internal as well as the external telephone number distribution of the
COMmander Basic are created with the configuration program COMset.
In order to execute a functional test via an internal call before the con-
figuration, an internal telephone numbering plan that is depending on
the type of used modules will be produced in the COMmander Basic
when you switch it on the first time. This default factory setting can be
restored later by pressing a key. (Attention! If you have already changed
some settings, these will also be replaced by the default factory set-
tings.):
Press the update button and keep it pressed. A short time later press
the reset button in addition - the case LED glows red. Now you keep the
update button pressed until the LED starts glowing orange. The initia-
lization is finished when the LED glows green.
The default factory settings (including the internal numbering plan) is
described in chapter The Default Factory Settings on page 42.
Serial Interface (V.24)
The serial interface of the COMmander Basic can be connected to the
serial interface of a PC (COM 1 to 4) or of a printer. On the mainboard
of the COMmander Basic are two connections „Serial interface“:
햲Between the 3-pole clamp bloc on the basic controller of the
COMmander Basic and the serial interface of the PC/printer a direct
connection with help of a corresponding cable can be made.
햳The enclosed case connector can be installed into the installation
chassis (chapter Install the V.24 Case Connector on page 12) and
can be connected with the 10-pole connector on the mainboard of
the COMmander Basic. The enclosed PC connection cable serves
for connecting the PC/printer with the case connector if necessary.
Only one of the connection option can be used at the same time (see
chapter Connect PC and Printer on page 33).

The S0 Module: Description and Connection 17
The S0Module: Descri ption and Connec tion
The COMmander 4S0module is contained once in the extent of supply
of the COMmander Basic. It has 4 S0ports that can alternatively be
switched as internal or external S0ports. The switching is done by an
attachment circuit board that serves as a jumper. In the extent of supply
the S0ports 1 and 3 are set as external S0ports, the other two as inter-
nal S0ports.
The connection to the S0ports is possible via fixed wiring to the 4
clamps b2, b1, a1 and a2.
Besides this you have a western modular plug on the S0port 1 and 3.
Depending on the use as an internal or external S0port, you can con-
nect directly an ISDN device or the NT to the COMmander Basic.

18 Description of the COMmander 4S0Module
Select internal/external S0Port
Please pay attention to the following issues when deciding which S0
port should be an internal or external one:
햲Even after the extension with several modules the
COMmander Basic may have a maximum of 4 external S0ports.
햳If you like to connect the COMmander Basic to NTs without wiring
efforts simply via a western plug cable, you must select the S0ports
1 and 3 as external S0ports (default factory settings). These allow
the direct connection via a western modular plug.
The S0ports can individually be switched over from internal to the exter-
nal by re-plugging the small jumper circuit boards on the connector
strips.
Please pay attention to the labelling on the COMmander 4S0module
and the white marks on the small jumper circuit boards and adjust them
correspondingly (compare Pic. 10 and Pic. 11).
Configure internal/external S0Port for the Operation
of an ISDN Emergency Telephone
The COMmander Autoswitch (Auerswald accessory) in combination
with a COMmander 4S0module extends the COMmander Basic for the
usage with an ISDN emergency telephone in case of a power failure. If
this additional plug is connected to a COMmander 4S0module, an
emergency ISDN telephone (e.g. the COMfort 1000 or the smar-tel-i by
Auerswald) is switched from the internal S0port directly to the external
S0port in case of a power failure. This telephone remains ready for
operation by switching over to the external S0port and is able to tele-
phone externally. It gets its emergency supply directly from the public
exchange.
In order to configure the S0ports correspondingly, remove the small
jumper circuit boards from the connector strips of two neighbouring S0
ports (S0port 1 and 2 or S0port 3 and 4) and put the
COMmander Autoswitch on these connector strips instead (see
Pic. 12). So you get an internal and an external S0port.
In order to set the emergency unit correspondingly, activate the emer-
gency mode authorization in a compatible ISDN telephone.
Enter an internal subscriber telephone number of the COMmander
Basic as 1st MSN into the telephone (chapter Configuration of ISDN
Devices on page 39). If the telephone allows further entries of MSNs,
external telephone numbers can be entered. It can be called in case of
a power failure. For this reason please use the external telephone num-
bers of the ISDN connection where the telephone is connected to in
case of a power failure. How to make these settings is described in the
manual of your telephone.
Connect the so prepared ISDN telephone to the internal S0port. If there
is no power failure, this telephone is operated on the internal S0port of
the COMmander Basic like the other units that are connected there.
If not only a single telephone has to continue its operation in
case of a power failure but a big portion of the PBX, you are
in need of an uninterruptable power supply, e.g. the USV-300/
-500 Sinus (Auerswald accessory).
If the external S0port operates as PTP connection, the telephone used
as an emergency telephone must be suitable for the operation on a PTP
connection and be switched over automatically to this operation mode
(the smar-tel-i by Auerswald needs the smar-tel-i operation better than
version 1.43).
On one internal S0port only one emergency telephone may be oper-
ated. On all the other suitable devices this function must be switched off
by all means.
In a fully extended condition the COMmander Basic can take a maxi-
mum of 4 COMmander Autoswitch because of the limitation to a maxi-
mum of 4 external S0ports.

The S0 Module: Description and Connection 19
Switch Termination Resistors
The termination resistors for the internal and external S0ports are to be
switched on or off with help of the DIL switch on the circuit board.
If the corresponding S0port of the COMmander Basic is at the begin-
ning/end of several units or if there is only one connection between two
units, the appropriate termination resistors need to be activated. (see
Pic. 13).
This is the case e.g. if the COMmander Basic is connected directly to
the NTBA as a single device which is always the case with a PTP con-
nection. (Exception: An ISDN connection box with integrated terminal
resistors was switched in between).
The termination resistors needs to be activated (see Pic. 14) e.g. if you
lay an internal S0bus to two directions starting at the corresponding
internal S0 port.
But you also have to deactivate the termination resistors if you con-
nected an external S0bus directly to the NT with termination resistors
in the last connection box and if you connect the COMmander Basic to
one of these connection boxes.
In the individual installation chapters the different possibilities will be
explained in detail again. (see chapter Connection of ISDN Devices to
the internal S0 Port on page 19 and chapter Connection to the NT on
page 22).
Meanings of the Light-Emitting Diodes
On the western modular plugs of S0port 1 and 3 you will find four light-
emitting diodes (see Pic. 15). The light-emitting diodes show the activity
on the different S0ports.
LED glimmers:One B-channel is busy.
LED glows:Both B-channels are busy.
LED short flash:D-channel message received.
LED is flashing with 0,5 Hz:Layer 1 is activated.
In the extend of supply of the COMmander Basic is one
COMmander 4S0module enclosed. This contains 4 S0ports that can
be connected alternatively as internal or external S0ports. (see chapter
Select internal/external S0 Port on page 18).
An S0port that was configured as an internal S0port, offers similar fea-
tures like an ISDN Point-to-Multipoint exchange line connection. Here
you can also connect up to eight ISDN units, a maximum of four of them
without an own power supply (that is the case with most of the ISDN tel-
ephones). All the devices should be certified Euro-ISDN devices in
order to guarantee a proper functionality.
On the S0ports 1 to 4 the connection of the ISDN devices is done via
attached ISDN wall jacks on the four clamps b2, b1, a1 and a2 (see
chapter Installation of additional ISDN Wall Jacks on page 20). If you
use the S0port 1 or 3 as internal S0ports, you also have the option to
use the built-in western modular plugs. Thanks to this you will have a
direct connection between the COMmander Basic and an ISDN device
or an ISDN Multiplug.
The connection cable of an ISDN device may have a maximum length
of 10 m. It is equipped with a western plug that you will plug into the
ISDN wall jack (Western modular RJ-45) as you can see in Pic. 16. (If
you like to remove the western plug out of the jack, you will have to
press the lever and pull at the same time to remove it.). In case of ISDN
devices with an own power supply you have to plug them into to the 230
V mains. Then all ISDN devices must be configured. (see chapter
Configuration of ISDN Devices on page 39).
An ISDN Device directly attached to the
COMmander Basic
If you only like to connect one single ISDN device to the internal S0port,
you can use the western modular plug that is on the circuit board, pro-
viding that it is the S0port 1 or 3. The connection cable must not be
longer than 10 m.

20 Connection of ISDN Devices to the internal S0Port
Several ISDN units connected to one ISDN Multiplug
The western modular plug available for the S0port 1 and 3 on the circuit
board can also be used for the connection of an ISDN Multiplug. Use
this option only in case all the ISDN devices that are to be connected to
the corresponding internal S0port are operating next to the
COMmander Basic and you like to do this without installing ISDN wall
jacks. The specialized dealers will offer you the ISDN Multiplug for this
kind of wiring (Auerswald accessory).
The connecting cables of the ISDN devices and the connecting cable
between the COMmander Basic and the ISDN multiple socket may
have a maximum length of 10 m. The termination resistor on the module
must be activated for the corresponding S0port (see Pic. 17).
Installation of additional ISDN Wall Jacks
If the ISDN devices should not be operated next to the
COMmander Basic, they must be connected via firmly attached ISDN
wall jacks. In this case the ISDN wall jacks are attached with a cable and
connected in parallel to the internal S0port (internal S0bus).
The S0bus consists of up to twelve parallel connected western modular
wall jacks. But the restriction applies that a maximum of eight ISDN
devices or four ISDN units without an own power supply are attached
like on the NT (Point-to-Multipoint connection).
The connection of the internal S0bus happens on the COMmander 4S0
module on the four clamps b2, b1, a1 and a2. This labelling of the
clamps is printed at the back of the clamp on the circuit board. The
clamp blocs can be detached from the module to simplify the installa-
tion.
The wires, stripped at the end, are shoved into the assigned openings
(see Pic. 19) until the right position for proper contact has been
reached. In order to remove a wire again, you have to open the clamp
by pressing the orange key that is on top of the opening with a screw
driver or a similar tool.
Normally you use an unshielded twisted pair cable for wiring installation
(J-YY 2x2x0,6 St III Bd). Under certain circumstances (e.g. near a
strong radio/television station or a power cable), you have to use a
shielded twisted pair cable.
In any case it should be twisted pair cable with four wire positioning like
in Pic. 20. Here both sending data wires (a1 and b1) as well as both
receiving data wires (a2 and b2) are positioned vis-a-vis. This cable
configuration will help to compensate interferences considerably.
