General information

The TA 33USB international is an ISDN communications system that enables you to connect up to
two analogue devices to a basic ISDN access (e.g. a telephone and a fax machine). In addition, when
used in conjunction with a PC equipped with a USB port, the TA 33USB international software that is
included in the package enable you to perform a variety of useful functions relating to communica­tions.

The two B-channels of an ISDN access can be used to establish two completely independent connec­tions (e.g. telephone calls), which means you can call your business partner on one channel while
simultaneously transferring data to a different destination on the other channel via your PC.

The TA 33USB international complies with the statutory requirements for communications systems.
You are permitted to mount and install it yourself.

The TA 33USB international supports the DSS1 protocol and can be operated on ISDN multi-terminal
accesses. It is not designed to be operated on ISDN point-to-point lines or system accesses.

Analogue devices can be operated on the TA 33USB international using either DTMF (dual-tone
multi-frequency) dialling with a Flash function or pulse dialling.

Note

The full range of features provided by the TA 33USB international can only be used by telephones
that support the DTMF dialling mode with a Flash function; telephones using pulse dialling do not
have the Flash function, which is necessary for making enquiry calls, for example, and do not have
any star or hash keys either, which are necessary to control certain features. The caller's telephone
number can only be displayed on telephones supporting this feature.

Mounting the device and putting it into operation

Mounting and installation sequence

The TA 33USB international consists of various components. This user guide first describes how to
mount the communications system and connect the terminals. Once you have completed this, you
will be able to use your system.

However, we recommend you to configure your TA 33USB international to your personal require­ments before using it. You can configure the system using either a telephone or by means of a menu
on a connected PC.
Please proceed as follows:

1. Mount the TA 33USB international and connect the terminals. This is described in the sections
immediately below.

2. Configure the system. You can do this in one of two ways:

• Configuration using a PC: in order to use the menu-supported PC configuration, all the drivers
on the CD supplied must first be installed. This is described in the section entitled “Data commu­nication” from page 16 onwards.

• Configuration using a telephone: use a connected telephone to configure the system. This is
described in the section entitled “Configuring the system using a telephone” from page 53
onwards.

3. Installation of the CAPI drivers. This is described in the section entitled “Data communication” .

With regard to points 2, 3 and 4, please note the system requirements listed in the section entitled
“What is needed to operate the TA 33USB international?” on page 7 above.

In the Appendix you will find a glossary, an index of key words and a visual representation of the
TA 33USB international’s audio signals and cadences.

9

Mounting the device and putting it into operation

Mounting location

The ambient operating temperature of the TA 33USB international must not be lower than +5°C or
higher than +40°C.

For this reason you should not mount your TA 33USB international

• in the vicinity of any heat sources (e.g. radiators),

• in direct sunlight,

• behind drapes or curtains,

• in small, unventilated or damp rooms,

•outdoors, or

• in the vicinity of combustible materials.

In addition, ensure that

• the room is dry and as free of dust as possible,

• no high-frequency equipment (e.g. transmitters, radiation equipment or similar devices) is in
the vicinity,

• no fluid can drop onto or into the device (this is very important),

• the wall on which the device is mounted is flat and even.

The following criteria are important when selecting the mounting site:

• there must be a mains socket with an earthing contact available nearby for the plug-in AC
adapter,

• the device must not be any more than three meters (approx. 10 ft) away from the PC if you want
to connect the two via USB

• the distance to the analogue terminals must not exceed three meters (approx. 10 ft).

Important note

In order to avoid injury and damage, the mains socket for the plug-in AC adapter must be installed
by a qualified electrician. Ensure that the socket is freely accessible at all times.
Provide a separate mains circuit for the TA 33USB international; short circuits caused by other house­hold devices will then not render your TA 33USB international non-operational. To protect it against
power surges, which can occur during stormy weather, we recommend installing a surge protector.
Consult your electrician for more information on this matter if necessary.

10

Mounting the device and putting it into operation

Mounting the TA 33USB international

You can simply place your TA 33USB international on a solid surface such as a table. Please note that
the rubber feet of the TA 33USB international may, under certain circumstances, leave unseemly
marks on the surface of your furniture.

Tools for wall mounting

To wall-mount the system you will require the following utensils:

• two 4 x 30 mm DIN 7996 buttonhead screws

•two 6 mm rawlplugs

•a 6 mm masonry drill bit (the type of drill bit you need depends on the wall)

•a percussion drill

•a screwdriver.

Wall mounting

Warning! Make sure that there are no supply lines, power cables, etc. where you plan to drill.
Drill the 6 mm holes for the upper and lower mounting screws 93 mm (3.66 inches) apart. Insert the
rawlplugs and fix the screws into the wall leaving a distance of 4 mm (0.15 inches) between the
screw head and the wall.
Then attach the back of the housing to the screws and pull it slightly downwards.

Connecting equipment

Warning! Do not connect the TA 33USB international during a thunderstorm. Arrange the cables so
that they cannot be stepped on, tripped or fallen over, causing injury.
Ensure that the connecting lines and cables are not bent, stretched or put under any mechanical
stress in any way.

11

Mounting the device and putting it into operation

Connecting the TA 33USB international to the ISDN network

The TA 33USB international has a general connection licence. This means that anyone may connect
the device to the network, but only if the following conditions are met:

• The device is only designed for Euro-ISDN basic access. Never connect it to lines or facilities in an
analogue network or to ISDN tie lines. This could result in malfunctions and/or damage to both
the TA 33USB international and the network.

• The Euro-ISDN basic access must be the multi-terminal type and equipped with a network ter­minator (NTBA) from your network operator.

Insert one end of the TA 33USB international's ISDN connector cable in the corresponding socket on
the NTBA and the other in the socket on the underside of the TA 33USB international.

Connecting a computer to the TA 33USB international

First connect the USB cable to the PC, then to the TA 33USB international.
When uninstalling, first remove the cable from the TA 33USB international and only then from the
PC.

A PC is not necessary for configuring and operating the TA 33USB international. It does, however,
simplify the programming of your communications system and provide various additional applica­tions in conjunction with the communications software.

Connecting the TA 33USB international to the power supply

The connection to the 230-V mains supply can only be carried out without risk if the instructions
below are followed very carefully.

• Position the mains cable behind the AC adapter to ensure that no-one can trip over it.

• Ensure that the socket and the AC adapter are easily accessible so that the adapter can be
unplugged from the socket quickly in the event of danger. This is also necessary because the

2a/b

13

TA 33USB international does not have a separate mains switch. The TA 33USB international can
only be completely disconnected from the mains by unplugging the AC adapter.

• Never unplug the adapter by pulling on the cable. If you want to disconnect the device from the
power supply, always pull the adapter itself out of the mains socket.

Caution!

Only use the AC adapter supplied, part no. 4505617. Other adapters can cause malfunctions or even
electric shocks or material damage.

Warning!

Never operate or continue to operate the device if the AC adapter is damaged.
This could be life-threatening due to risk of electric shock.

If the AC adapter plugged in is damaged:

• First turn the power off at the mains before unplugging the AC adapter.

• The AC adapter must not be repaired. Purchase a new adapter from your supplier if you notice
any sign of damage.

• Never remove the AC adapter supplied from its connection cable. This could be life-threatening
due to electric shock. Use a suitable extension cable from a specialist dealer if the adapter plug
cable cannot reach a socket.

Mounting the device and putting it into operation

Power Supply Socket

Telecommunications systems can be affected by interference from the power supply originating
from other electrical devices. This is a known issue with photocopiers, laser printers, electric type­writers, air conditioning units, fan heaters, vacuum cleaners and refrigerators in particular. For this
reason, the following points must be observed:

• Connect the TA 33USB international to a socket which is as far away as possible from the sock­ets for the devices mentioned above. The ideal situation would be to have a separate power
supply for the TA 33USB international .

• Ensure that the AC adapter is safely and securely inserted into the socket at all times. Loose
plugs and sockets represent a fire hazard.
Such danger spots must be repaired immediately by an electrician.

• Use only socket adapters with an adequate level of safety. This can only be guaranteed for
adapters with a safety registration code displayed on the outside (e.g. with the CE symbol, previ­ously the GS symbol for approved safety). Otherwise malfunctions may occur when operating
the TA 33USB international , including a risk of fire in the event of a fault.

Note

Provide a separate power supply to the 230-V connection for the TA 33USB international . This
excludes the risk of short circuits from other existing devices rendering the TA 33USB international
non-operational.

To protect against surges, which can occur during thunderstorms, it is advisable to install a surge
protection device. Contact an electrician for specialist advice.
Following correct assembly and installation, connect the TA 33USB international to the power sup­ply. The AC adapter socket is located on the underside of the TA 33USB international . Insert the AC
adapter cable plug into this socket. Then plug the adapter into the mains socket.
If the LED is continually illuminated, the TA 33USB international is connected to the power supply.
In the event of an error, please first attempt to rectify the fault using the “Troubleshooting” table.

15

The default settings of the TA 33USB international on delivery

The following default settings and features are active on delivery:

• The secret personal identification number (PIN) is set to “0000” (four zeros).

• Incoming calls are signalled on both connected terminals.

• The analogue line 1a/b has the internal telephone number “11”.

• The analogue line 2a/b has the internal telephone number “12”.

• Trunk line access rights: all of the terminals have unrestricted rights and can be used to dial
international calls.

• When you lift the handset, you will hear an external dialling tone (i.e. automatic trunk line
seizure is active).

• Your own telephone number is transmitted to and can be displayed on the remote subscriber's
terminal when you make an external call.

• All of the ports are set to the “Telephone” terminal type.

• Call waiting is deactivated.

• The emergency numbers “999” and “112” can be dialled.

• The blacklist is deactivated.

We recommend that you configure your TA 33USB international to suit your own requirements
before using it. You can do this by means of either a connected telephone or the software supplied.
You can reset your device to the default state at any time.

Setting the Dialling Mode

• Analogue devices using the DTMF dialling mode and flash function are detected automatically.
No settings need to be made.

• Analogue devices using pulse dialling must be checked in before being used for the first time. To
do this, lift the telephone handset and press any digit other than “1”. Replace the handset. The
dialling mode will be detected automatically.

If at a later stage a DTMF signal is detected on a line which has been set for pulse dialling, the
TA 33USB international will automatically switch back to DTMF operating mode. It is therefore advis­able to avoid using hand-held transmitters or signal transmitters for the remote querying of answer­phones on devices using pulse dialling

Mounting the device and putting it into operation

Data communication

The communications software supplied enables your PC to use the following ISDN services via the
USB port: data transfer, reception and transmission of e-mails and Class 3 and 4 faxes, mailbox con­nections, an answerphone function and Internet applications.

System requirements

The following requirements must be met in order to install the PC software for the TA 33USB inter­national:

• IBM or a fully compatible PC,

• Pentium II CPU with a speed of 266 MHz or higher,

• at least 64 MB of main memory,

• Microsoft Windows 98/Me/2000/XP,

•a CD-ROM drive, and

•a USB port.

Important note

Before you install the drivers for the TA 33USB international, you must first uninstall any other CAPI
drivers that may be present (e.g. from a previously used ISDN card). Please also refer to the descrip­tion of the “Cleanreg.exe” program.

The components of the PC software

The software on the CD-ROM supplied consists of several components.

The TA 33USB international software

This provides the following functions and interfaces:

• Common ISDN Application Programming Interface (CAPI)
This standardised interface is used by applications that provide data transfer functions.

• Telephony Application Programming Interface (TAPI)
This interface is also standardised and enables the remote control of the terminals connected to
the TA 33USB international.

• CapiPort drivers
These drivers are utilised by the Windows “Dial-up network” component. The dial-up network
enables the Internet to be accessed without the need for special software from an Internet ser­vice provider (ISP). It can also be used to dial into a corporate network, for example.

17

Data communication

• Configuration of the communications system (set-up)
This program enables you to use your PC to configure your TA 33USB international to your own
requirements. It enables you to do this easily and gives you a comprehensive overview.

• System software update (FlashLoad). This enables you to update the operating system of your
TA 33USB international whenever additional features become available in the framework of
ongoing product development.

• CapiControl
This program provides you with a quick overview of the data transfer status and enables you to
configure several of the CAPI interface parameters. You will find this program in the Windows
taskbar.

•

Cleanreg.exe

The “Cleanreg.exe” program uninstalls any components that may be left over from previous
CAPI installations. We recommend that you run this program after you have uninstalled your old
CAPI installations.

Driver software with CAPI / TAPI

CAPI and TAPI are standardised software interfaces allowing data and telephony applications to use
the ISDN functions of basic and primary multiplex accesses (TAPI also performs this function for a
modem / analogue access). The drivers for the data module of the TA 33USB international control
the communications processes and the data transfer.

18

Data communication

Installing the software

Before you begin the new software installation, please ensure that any previous ISDN installation
that may be present on your PC is uninstalled. No other CAPI drivers may be present on your PC as
this can lead to conflicts between the different CAPI drivers.

Please run the “Cleanreg.exe” program that you will find on the installation CD-ROM. This program
uninstalls any components that may be left over from old CAPI installations.
This program is in the root folder of the CD-ROM.

Before you install the TA 33USB international software, please boot your PC and start up Windows.
Keep your Windows operating system CD-ROM handy as you may require it in the course of the
installation procedure. In order to configure Internet access you will also require the access data
issued to you by your ISP.

It is easiest to install the software when your PC has not been connected to the TA 33USB interna­tional yet. The installation can still be performed when the PC has been connected, of course. In this
case, the hardware wizard opens and prompts you for drivers for the unknown device. Insert the CD­ROM in the drive and, if necessary, key in the correct path to the drive.

Now you can configure your TA 33USB international (see the following pages for details).

21

Data communication

Configuring the system using a PC

If you attempt to configure your system from a PC when the configuration mode has already been
activated from a connected telephone, you will see an error message on your monitor. Similarly, if
the system is being configured from a PC, any attempt to open the configuration mode from a con­nected telephone will result in you hearing a busy tone.

The configuration procedure does not interrupt the operation of the communications system, so you
can continue to make calls normally. Any changes made to the configuration will only take effect
once the configuration file has been exported to the system.

Start the TA 33USB configuration program in the “TA33USB” program group.

You can select whether you want to configure your system online or offline, i.e. with or without
being connected to the system.

Access to the configuration program in the online mode is protected by a PIN. This PIN is “0000”
(four zeros) in the default setting (as on delivery) and corresponds to the PIN that you require to acti­vate the configuration mode from a telephone. If you configure the system offline, you will have to
enter the PIN in order to export the data to the system.

Note

If you select “Offline configuration” you can save the configuration data to your hard disk under a
name of your choosing. You can subsequently load any of the configurations you have saved to your

22

Data communication

TA 33USB international as required. This means that you can create several configurations for vari­ous purposes, and then simply load one of them to your system whenever it is needed.

When the configuration software has started, you can edit a broad range of settings for your
TA 33USB international.

Select the relevant input screen by clicking on the corresponding key word in the menu items visible
on the left-hand side of the screen.

The screens “ISDN telephone numbers”, “Call allocation” and “Internal ports” contain explanatory
images / texts.
You can find the corresponding inputs / settings in the following input screens described below:
“ISDN telephone numbers”, “Call allocation”, “Internal ports”, “Call forwarding” and “Further fea­tures”.

Data communication

ISDN telephone numbers

Key in the telephone numbers (MSNs) issued to you for your ISDN access by your network operator,
but don’t include the local area code.

25

Data communication

Call allocation

Allocate one or more telephone numbers (MSNs) to the connected telephones. Incoming calls for
the corresponding telephone number (MSN) are signalled on the terminal allocated. Obtain the tele­phone number of the SMS centre from your network operator and key it into the appropriate field.
In addition, specify the line (port) to which your SMS-capable telephone is connected.

26

Data communication

Internal ports

Trunk line access rights: class of service for the external line

You specify the trunk line access rights for both connected terminals.

Internal only: can neither make nor receive external calls.
Outward restricted: cannot make external calls. No restrictions on incoming calls.
Local area: can only make external calls to numbers not requiring the prefix “0”. No restrictions on

incoming calls.

National: can only make external calls to numbers not requiring the prefix “00”. No restrictions on

incoming calls.

International: no restrictions on either incoming or outgoing calls.

Terminal type

Select the type of terminal connected to each of the lines (ports) so that the TA 33USB international
can manage the corresponding terminal type correctly. This ensures that fax transmissions are not
interrupted by call-waiting tones, for example.

Note

Only one line can be configured to “Answering machine” at any one time.

27

Data communication

Call-waiting protection

Specify whether calls coming in during a conversation are to be indicated by means of call-waiting
tones or not.

Telephone number transmission

Select the telephone number (MSN) that is to be transmitted from the respective terminal to the
called subscriber during an outgoing call.

Call forwarding

Note

Your selection of the input screen “Exchange” or “System” specifies the call-forwarding type.

Depending on your choice here, one of the two screens will open.

Call forwarding in the system

In the case of call forwarding in the system, you specify a forwarding destination for incoming calls
to each of the connected terminals.
If a call is forwarded to an external destination, both B-channels will always be busy for the duration
of the forwarded call, i.e. the access will be busy. The costs incurred for the forwarded call are billed
to the line from which forwarding was initiated.

28

Data communication

Call forwarding in the exchange

In the case of call forwarding in the exchange, you specify a forwarding destination for incoming
calls to your telephone numbers / MSN. The difference to call forwarding in the system is that even
when a call is being forwarded, your access can still be contacted via other telephone numbers /
MSNs
In order to be used, this feature must be available on your access.

The alternatives for both types of call forwarding are the same. You can select the following condi­tions:

Call forwarding immediately: an incoming call is immediately forwarded without being signalled on

the terminal originally dialled.

Call forwarding on busy: if the dialled terminal is busy, every subsequent call is immediately for-

warded to the given terminal.

Call forwarding after a set time: the call is first signalled on the dialled terminal, but if it is not taken

within approx. 20 seconds it is forwarded to the destination that has been set.

29

Data communication

Fur ther features

In this input field you can edit the settings for your communications system. These settings apply to
both connected terminals.

Seizing a trunk line

The setting “with a 0” means that you have to press the code digit “0” before you can dial an exter­nal telephone number. The default setting is “automatically”: in this case, you can dial the external
telephone number immediately. Please note that when this setting is active, internal calls cannot be
made from terminals using pulse dialling.

“Telephone number busy” feature

When this feature is active, any further calls to this telephone number / MSN (i.e. calls during an
existing conversation) are met with a busy tone.

Emergency telephone numbers

You can configure three emergency telephone numbers that can always be dialled from any tele­phone and are not dependent on trunk line access rights (“999” and “112” are preset). You can also
use one of the emergency telephone number stack entries to store, for example, an area code (e.g.
“020” for London). Telephones with no external access can thus make calls in this area, while exter­nal calls to all other areas remain blocked.

30

Data communication

Automatic keypad signalling

If you operate the TA 33USB international as a sub-system, depending on the type of main system
you are operating it may be necessary to switch the signalling procedure from “Keypad” (default set­ting) to “Telephone number”. This will deactivate the automatic switchover to keypad input trig­gered by the star or the hash key (#). The star and hash keys can then also be used to transmit
dialling information. Please refer to the documentation of your main system for the required sig­nalling procedure.

Note

Keypad signalling is required by some network operators and system manufacturers in order to acti­vate features.

Blacklist

In the blacklist you can enter any telephone numbers that you don’t wish to be dialled from your
communications system (this also applies to Internet connections established via dial-up network­ing).
The telephone numbers entered in the blacklist apply to the analogue subscribers and to connec­tions made via the CAPI applications.

Example: in order to block calls to premium rate numbers, you just enter “0190” in the blacklist. Any

attempt to dial the sequence “0-1-9-0” will then be aborted. You can enter up to five telephone
numbers if you wish.

The three blacklist input screens at the bottom already contain some preset dialling codes that can
be attached to those numbers you want to block, for example international codes and network
dialling codes.
Any numbers blacklisted by you that are prefixed by theses codes are thus recognised and blocked.
You can edit these entries as desired, and use the “#” (hash symbol) as a wildcard standing for any
digit.

31

Data communication

Invoking the program from the Windows taskbar

In the lower right-hand corner of the Windows taskbar you will see the icon illustrated, in the form
of an LED for each of the B-channels (Windows 98/Me/2000/ XP).

The colour of the icon represents the status of the CAPI interface.

The colours have the following meanings:
Red - deactivated
Yellow - not connected to device

Data communication

Configuring Internet access

The following example describes the configuration of a dial-up networking entry under Windows 98.
Proceed analogously to set up Internet access under other operating systems.

Requirements: in order to access the Internet from your PC, you require a “Internet Service Provider”
(ISP), who will provide that access. Your ISP will supply you with the following data, which you need
to configure your access:

-a dial-up number,

-a user name, and

-a password.

In addition, an Internet browser must be installed on your PC (e.g. Netscape Communicator or
Microsoft Internet Explorer).

If you have any questions with regard to your access data, please contact your ISP.
An additional requirement is that the “Dial-up Networking” folder is present on your PC. Check that
this is the case by double-clicking on the “My Computer” symbol.

The “Dial-up Networking” folder should be visible here. If this is not the case, then please install the
Windows component “Dial-up Networking” from your Windows CD-ROM. You can find information
on how to do this in the operating system documentation.

To establish a connection to your ISP, proceed as follows:

Open the “Dial-up Networking” folder and double-click on the icon “

Make New Connection”.

35

Making calls

Making calls

Basic information

The full range of the TA 33USB international features can only be used when the dialling mode of
the connected terminals is set to DTMF with a Flash function.
Terminals with pulse dialling cannot execute functions requiring an R-key, a star or a hash key.

Note

You should not use a DTMF device (e.g. a handheld transmitter) to establish a connection to a pulse
dialling terminal. If you did this, it would cause the TA 33USB international to reset this terminal to
the DTMF mode, which would block it from further dialling. (The terminal can be unblocked again
by keying in any digit except “1”.)

Taking calls

Your telephone rings: internal or external call. Please refer to the Appendix for information on the
various ring cadences.

b

Lift the telephone handset.

c

Conduct an internal or external conversation.

d

End the call by replacing the handset.

Displaying the caller's telephone number

The TA 33USB international supports the display of the caller's telephone number (CLIP) on suitably
equipped analogue terminals if the feature is provided by your telephone company.

39

Making calls

What is an “external call” and what is an “internal call”?

An external call is a call to a subscriber who is not connected to the same TA 33USB international
that you are. An external call thus requires a trunk line, i.e. an external line, which it has to “seize” in
order to make the call. An internal call is a no-charge call to a subscriber who is connected to the
same TA 33USB international that you are. This applies to the analogue ports of the TA 33USB inter­national, but not to the looped-through ISDN bus. Terminals connected to this bus are connected
parallel to the TA 33USB international, which means that no-charge calls between the analogue ter­minals connected to the TA 33USB international and those connected to the looped-through ISDN
bus are not possible.

40

Making calls

Automatic and manual trunk line seizure

Depending on your requirements, you can configure your TA 33USB international so that a trunk line
is seized automatically when you lift the handset or manually when you dial “0” (see the section

c

After lifting the handset you will hear an external dialling tone and can dial an
external telephone number immediately.

r

To make an internal call, press the R-key.

t

You will then hear an internal dialling tone and can dial an internal telephone
number (“11” or “12”).

Note

If the trunk line is automatically seized, analogue terminals with pulse dialling cannot dial internal
telephone numbers.

Manual seizure

c

After lifting the handset you will hear an internal dialling tone and can dial an internal
telephone number immediately.

0

To make an external call, press “0”. This seizes an external line and you then hear an

48

Keeping in touch

Call forwarding

You can forward calls from an internal to an external terminal or from one internal to another inter­nal terminal. Depending on the configuration, this call forwarding is carried out either in the
TA 33USB international or the exchange (in the latter case, this will incur charges). Internal call for­warding must be activated in the TA 33USB international (see page 64).
When you activate call forwarding, it applies to a line and the telephone numbers allocated to it. To
use call forwarding, therefore, your numbers must first be stored and allocated (see the section enti­tled “Storing your telephone numbers” on page 56).

Three different types of call forwarding are possible:

Immediate (code digits “71”): an incoming call is immediately forwarded without being signalled on

the terminal originally dialled.

After a set time (code digits “72”): the call is first signalled on the dialled terminal and is forwarded

to a preset destination after a certain time. The delay is set at around 20 seconds.

On busy (code digits “73”): if the dialled terminal is busy, the call is immediately forwarded to the

preset terminal.
If the “Immediate” call forwarding option is activated, you will hear a special dialling tone if manual
trunk line seizure is active.

Special settings / features

The blacklist

You can program a common blacklist for both the analogue terminals connected to the TA 33USB
international. This list can contain up to five telephone numbers or parts of telephone numbers. You
program these numbers in the Configurator.
With the aid of the blacklist, you can prevent subscribers from dialling undesirable phone numbers.
Any attempt to dial a number listed in the blacklist results in the dialling procedure being aborted as
soon as the blacklist detects such an attempt, followed by a negative acknowledgement tone.

blacklist, please check the numbers listed so that you do not block dial-in numbers that you may
require. The blacklist contains some pre-set numbers.

52

Special settings / features

Emergency numbers

In configuration mode you can configure two emergency telephone numbers that can always be
dialled from any telephone and are not dependent on trunk line access rights. You can also use one
of the emergency telephone number stack entries to store, for example, an area code. Telephones
without external access can thus make calls in this area, while external calls to all other areas remain
blocked.

53

Configure the system using a telephone

You can configure the TA 33USB international and edit the pre-programmed settings to meet your
personal requirements. You can do this in one of two ways: by means of a menu on a connected PC
(see the section entitled "Configuring the system using a PC" from page 61 onwards) or by means of
a connected telephone (which must support DTMF dialling).

To configure your system using a telephone, please proceed as follows:

• Activate the configuration mode by keying in your personal identification number (PIN). The

default setting is "0000" (four zeros).

• Begin every configuration procedure by lifting the handset and complete it by replacing the

handset after you have heard a positive or negative acknowledgement tone.

• If you hear a negative acknowledgement tone, the procedure is interrupted and the entries you

have made for this procedure are lost. You then have to restart and carry out the procedure
again. As soon as you hear a positive acknowledgement tone, it means that your entries have
been saved.

• When you have completed the configuration, deactivate the configuration mode. If you fail to

do this manually, it will be done automatically four minutes after you have replaced the handset
or made your last input.

Call protection is automatically activated on the telephone you are configuring from while the con­figuration mode is active, which means that you cannot receive calls.

In configuration mode you always hear the special internal dialling tone on lifting the handset.
If you attempt to configure the TA 33USB international from a telephone while configuration is
being carried out from a PC or another connected telephone, you will hear a busy tone.

Programming Other Settings

Before you can carry out any programming on the TA 33USB international, you need to switch the
programming mode on. This then remains active for 15 minutes before being switched off automat­ically. You can also switch the programming mode off manually by entering a code. Please note that
whilst the programming mode is active, no outgoing or incoming calls are possible on any terminals
connected to the TA 33USB international.
Programming is carried out using a DTMF telephone which is plugged into one of the RJ11 sockets
on the front. This telephone is also used to switch on the programming mode on.

54

Configuring the system using a telephone

Once you have switched the programming mode on, you start the individual programming proce­dures by lifting the handset. After a few seconds you will hear a series of very short high-pitched
tones (programming tone). Your inputs have been saved once you hear a low-pitched tone for one
second (positive acknowledgement tone).

Invalid inputs are rejected with three short high-pitched tones (negative acknowledgement tone).
End the programming sequence by replacing the handset. Replacing the handset before acknowl­edgement will cancel the programming process.
Please do not forget to switch the programming mode off again when you have finished program­ming.

Managing call forwarding

You can specify whether call forwarding is to take place in the TA 33USB international (this is the
default setting) or in the exchange. There are various advantages to both methods. Call forwarding
in the exchange has to be ordered from your network operator.
In the exchange, the telephone number allocated to the terminal that activated call forwarding is
diverted. Call forwarding using the TA 33USB international saves you the additional monthly fee, but
seizes both user channels simultaneously, which means that no further external calls are possible as
long as a call is being forwarded.

Notes on the configured SMS line

If a call is forwarded from the SMS provider to the SMS line on the TA 33 USB international:

• there is no compatibility check,

• any call forwarding configured for this line is not carried out,

• there is no validation check, and

• call waiting is not signalled.

If a call is already active on the SMS line, calls from the SMS provider will be rejected: SMS calls do
not trigger a call-waiting tone.

Automatic keypad signalling

If you operate the TA 33USB international as a sub-system, it may be necessary to switch the sig­nalling procedure from “Keypad” (default setting) to “Telephone number”, depending on the type of
main system you are operating. This deactivates the automatic switchover to keypad input triggered
by the star or the hash key. The star and hash keys can then also be used to transmit dialling infor­mation. Please refer to the documentation of your main system for the required signalling proce­dure.

Troubleshooting

If your system or one of its accessories fails to function correctly, please report it to your supplier's
customer service department.

However, before doing so, disconnect the AC adapter plug from the mains, then plug it in again, as
your system may be in an undefined state. In this case you can clear the “fault” by means of this pro­cedure.

External calls are not possible

• Check whether the telephone cable and the ISDN cable are firmly plugged into their sockets on

The primary aim of the legislation is the prevention of waste electrical and electronic equipment,
and also the recycling, material recovery and any other form of recovery of such waste in order to
reduce the quantities of waste to be disposed of and the amount of hazardous substances from elec­trical and electronic equipment in waste.

The product that you have purchased was developed in line with the current state of the art in an
environmentally friendly manner and with a view to recycling. It therefore meets the specifications
of the European directives.

The product is labelled with the symbol illustrated above. If you wish to dispose of this product, this
symbol obliges you to do so separately from unsorted domestic waste. Suitable facilities have been
set up for the return of waste electrical and electronic equipment. Waste equipment can be handed
in at these return centres free of charge. To find out where these return centres are located, please
consult the information provided by the department of your local authority responsible for waste
disposal.

Please note:

Electrical equipment does not belong in household waste.
Deposit it free of charge at a return centre.

Glossary

a/b line

Line for analogue terminals using RJ11 sockets.

CLIP (Calling Line Identification Presentation)

Display of the calling subscriber’s number on suitable terminals (this feature depends on whether
the number is transmitted and whether this service is provided by the network operator).

DTMF dual-tone multifrequency

Dialling via internationally standardised tones of different pitches assigned to the digit keys and the
star and hash keys. This means that functions at the exchange can be controlled, e.g. callback on
busy, and answerphones can be operated remotely.

Flash function

Function of the R-key or, where applicable, of another key on your terminal (flash detection of the
TA 33USB international: 60 to 350 ms).

Keypad signalling

For controlling special functions on the ISDN network (if provided by the network operator).

Line code digit

Code digit assigned to the a/b lines (0, 1 or 2).

MSN

With your ISDN basic connection, your operator provides you with several telephone numbers (Mul­tiple Subscriber Numbers) which can be allocated to different terminals.

Pulse dialling

Dialling mode via electrical pulses; no input via the star and hash keys is possible.

SMS (Short Message Service)

SMS are text messages which you can receive on suitable terminals. The prerequisite is that your
network operator supports SMS and CLIP.

Telephone number code digit

The code assigned to the telephone numbers (MSNs).
