Description
The PABX is an ISDN telecommunications system (PABX) for interfacing with the Euro ISDN (DSSI) protocol). The
PABX system is equipped with an external ISDN port that is configured for connecting to the ISDN access point of the
network service provider. You can set the ISDN port either as an internal or external ISDN port. You can program the
type of connection for the external ISDN connection either as a multipoint connection or as a point-to-point connec-
tion (default setting). Depending on the type of PABX, up to eight (8) analog terminals can be connected (base mo-
del). You can use door intercom units as modules in the PABX system, or as additional devices at the internal analog
port. Module slots for ISDN and a/b ports, contacts modules, 4 DSP modules and up to 4 analog access lines (POTS)
are also provided. User-specific answering machines (voiceboxes) can be used after installing the optional Com-
pact-Flash Card. Internal numbers (the destination for the extension number with point-to-point connection) bet-
ween 0... 99 can be freely assigned. The features provided for analog terminals can only be used with terminals which
use tone dialing and which are equipped with a flash button. Flash duration detection can be set by PC configuration.
Analog terminal devices that use pulse dialing can not be used for functions or codes. Please note that the buttons on
some ISDN terminals available on the market may limit the use of the features provided by the PABX system.
All terminal devices connected to the system must be »TC Terminals Guideline« or »R&TTE Guideline« approved.
The PABX system also provides all of the functions necessary for high-speed Internet access for a single pcs, or for
complete LANs via xDSL or ISDN. Here the firewall integrated into the PABX system, together with the NAT (net-
work address translation) function, provides the necessary security; the functions DHCP server and DNS proxy en-
sure that the scope of configuration, both for your PABX system and your PC, is kept to a minimum.
Internet access for all of the PCs connected to the PABX system is provided via one single connection (SUA - single
user account); only one set of access data is required from your Internet service providers (ISP).

For a description of the features please refer to the online help for the »Professional Configurator« or the user infor-
mation on the CD.
Note
The first time you start the Configurator you will be asked to enter your user ID and password. Use »Service«
as your user ID and also »Service« as the password. Please note that these words are case-sensitive! Once
you’ve been logged on to the Configurator you can change your user ID and password as you like.
Safety notes
Important notes for using the PABX system
·Unauthorized opening of the PABX and improper repairs may result in risk of injury for the user.
·Unplug the 230 V AC connector plug before removing the enclosure cover and working on the ca-
ble terminal bay. Replace the cover before reconnecting the 230 V AC connector.
·Do not expose the inside of the PABX to any liquids; this would pose arisk of electrical shock. If
you expose the inside of the PABX to liquids the PABX can be destroyed.
·You should not connect or disconnect any lines during thunderstorms.
Important notes for using the PABX system Description
1

·Only terminals with SELV and/or which comply with ETS 300047 may be connected to the PABX
system. This regulation is fulfilled when approved terminal devices are used as intended.
·Find an appropriate installation location. The distance from the network termination (ISDN con-
nection) of your service provider and the 230 V AC outlet should not exceed 1. 5 meters.
·Water or heating pipes near the installation location can be used to install functional grounding.
Ensure that these lines are connected to the grounding circuit connector of your house service
connection.
·The PABX is powered by a 230 V AC utility outlet. Please ensure that the electrical outlet (groun-
ding outlet) for the PABX (and for additional devices where required) is installed such that it is
freely accessible at all times and that it is installed by a qualified electrician to prevent any risks of
personal or material injury/damage! Where at all possible, provide a separate power circuit for
the 230 V AC connection of your PABX system. This protects your PABX from short-circuits that
may occur in other in-house equipment.
·We recommend installing an overload protection to protect your PABX against surge that can so-
metimes occur during thunderstorms. For further information please contact your local electrici-
an.
·To prevent mutual interference, do not install your PABX system in the immediate vicinity of
electronic devices such as stereo equipment, electronic office equipment or microwave units.
Avoid installing your PABX near sources of excessive heat, e.g. radiators or in rooms with exces-
sive humidity.
The ambient temperature must not exceed 40° C.
Cleaning
Please observe the following points: You can clean your PABX without any difficulties. 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 damage the
electronics in the system. Always ensure, however, that no moisture penetrates into your PABX, as this could result
in damage to the PABX.
Loss of power
On loss of power (230 V AC power supply) the PABX is not operational, meaning that you can make neither internal
nor external calls. An ISDN terminal device with emergency power capabilities can continue to be operated however.
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 programmeming are unaffected by a loss of power.
Symbols
Please note: Different terminal devices will not necessarily have the same dial tones, ringing signals or procedures for
use.

Note
For a description of the features please refer to the Description of functions on the CD.
Not all of the features described here may be implemented in the standard ISDN connection supplied by your net-
work service provider. Contact your service provider to determine which features come standard with your ISDN ac-
cess and which ones you must apply for separately.
If your phone is set for »Automatic line access« you must first press the *key when you lift the handset b before be-
ginning any internal call procedures. The symbol bis highlighted in color, as shown in the example below, for the
corresponding performance feature.

Making phone calls
Some terminal devices use their own special procedures for the functions described in the following. Refer to the ope-
rating instructions for the terminal device being used for detailed information.
Only telephone connections, i. e. calls between subscribers, are presented in the following usage procedures as exam-
ples. For analog telephones, these functions are only described for tone dialing terminal devices equipped with a
flash key. The tones and signals described below are heard when using analog telephones. These tones may be diffe-
rent for ISDN telephones and analog telephones which generate their own dial tones. Other information may also be
shown in the display of these telephones.
Note
Please note: ISDN terminal devices connected to the ISDN connection may not have the same signals, ringing cycles
or operating procedures as the internal terminal devices for the PABX system.
