Safety Precautions

Before you set up or use the TA

33clip ...

...please ensure that you observe

the instructions in this guide. We

are legally required to inform

you of important precautions

you need to take in order to

ensure your own safety and

avoid damage to the TA 33clip

and to other devices.

If these instructions are not

observed, the manufacturer can-

not accept any liability for dam-

age arising from negligent or

deliberate disregard of the

instructions in this guide.

Only devices supplying SELV

(safety extra-low voltage) may

be connected to the TA 33clip.

• The correct usage of permit-

ted devices meets this

requirement.

• Do not open the casing.

Unauthorised opening of the

casing and incorrect repairs

may result in risks to the

user. It also renders the war-

ranty null and void.

• Do not allow any liquid to

penetrate into the interior of

the TA 33clip as this could

result in electric shocks or

short-circuits.

• Position the connection

cables so as to prevent acci-

dents.

• Do not install your TA 33clip

- in the vicinity of heat

sources,

- in direct sunlight,

- in the vicinity of other

electrical devices.

• Do not allow the device to

come into contact with

Getting to Know Your TA 33clip

Safety Precautions

damp, dust, caustic liquids or

vapour.

• Plug the connection cables

only into the appropriate

sockets .

• Connect only permitted

accessories to the device.

• Use only the AC adapter sup-

plied, part no. 4505617.

• Use only a slightly damp

cloth to clean the device

• Do not use the TA 33clip in

damp areas (e.g. bathrooms)

or in areas where there is a

risk of explosion.

Getting to Know

Your TA 33clip

General

The TA 33clip terminal adapter is

used to operate analogue equip-

ment such as telephones

(including DECT base stations),

fax machines (Classes 2 and 3)

and analogue modems (28,800

Baud) on an ISDN basic access.

You can use the two user chan-

nels (B-channels) for two inde-

pendent external calls (e.g. tele-

phone conversations). You can

call someone whilst at the same

time transferring data to a busi-

ness contact from your PC (using

an analogue modem).

The TA 33clip can be operated

on an ISDN multi-terminal access

using the DSS1 protocol or in a

telecommunications system on

the internal S

bus.

The TA 33clip supports calling

line identification presentation

(CLIP) and the reception of text

messages (SMS) on suitable ter-

minals (depending on the net-

work operator).

In the default setting on deliv-

ery, keypad signalling is also

supported. This means that you

can control features on the

ISDN network (for more infor-

mation, see page 36).

On the TA 33clip you can oper-

ate analogue telephones with

dual-tone multifrequency

(DTMF) dialling and flash func-

tion (60 to 350-ms flash time

detection) or terminals with

pulse dialling. However, you

can only use the full range of

features on telephones with

DTMF dialling and flash. Pulse-

dialling telephones do not have

a flash function, a star or a hash

key, all of which are required to

control the TA 33clip features

and/or the features of any

Getting to Know Your TA 33clip

telecommunications system to

which the TA33clip is con-

nected as a sub-system.

The following restrictions apply

when using telephones with

pulse dialling:

• Internal dialling and call pick-

up are not possible.

• Accepting a waiting call is

only possible by replacing

the handset and raising it

again.

• For all call processing proce-

dures, e.g. toggling, press

the digit “1” instead of the R-

key. However, you cannot

return to the previous status,

e.g. to the held call, by press-

ing this key again, as you can

with dual-tone multifre-

quency telephones.

Use of the following ISDN fea-

tures is only possible using a

telephone with dual-tone mul-

tifrequency:

Calling line identification

restriction (CLIR) for a call, setup

or blocking of call waiting (CW),

call forwarding (CFU, CFB,

CFNR) and completion of call to

busy subscriber (CCBS).

When operated on an ISDN

access, the TA 33clip behaves

just like a digital terminal. This

means that up to seven addi-

tional digital terminals can be

connected in parallel to the TA

33clip.

Symbols Used

Lift the handset

Replace the handset

Your telephone is ringing

Conduct your conversation

Press the R-key

Press the star key

Press the hash key

Dial a number or press a

code digit

You will hear a tone, e.g.

dialling tone, busy tone,

acknowledgement tone,

Operating Display

The LED above the sockets for

the analogue lines is:

• continuously illuminated:

TA 33clip power supply is on.

• flashing: If you hear the busy

tone approx. five seconds

after lifting the handset and

the LED starts flashing, the

ISDN connection cable is not

plugged in or the NTBA is

faulty.

To stop the flashing once you

have successfully connected

to the ISDN, lift the handset,

wait for approx. five seconds

and then replace the hand-

set.

Mounting and Commissioning

Mounting and

Commissioning

To install the system, follow the

steps in the order below:

• Check the requirements for

installation

• Familiarise yourself with the

components supplied

• Connect the devices

• Commission the ISDN

adapter

• Program the telephone num-

bers (MSNs) for the analogue

lines

Requirements

In order to be able to assemble

and commission the ISDN

adapter correctly, you require a

Euro-ISDN basic access using

the DSS1 protocol (for multi-

terminal access), and a network

terminator (NTBA) from your

network operator, installed and

ready for operation. The

adapter is not designed for

operation on a system access

and such operation may cause

faults.

What Is Included?

Check that the contents of your

package are complete:

• One TA 33clip user guide

• One TA 33clip terminal

adapter

• One AC adapter with a 3-m

connection cable

• One ISDN connection cable,

length 3 m

Setting up the TA 33clip

Wall Mounting

The correct mounting location

should meet the following

requirements in order for the

device to function safely and

without faults.

Choose a mounting location,

• where there is absolutely no

risk of liquid dripping onto the

device and entering the device

through the vents,

• on a wall which is level and

stable, and

• in an area which is as free of

dust and as dry as possible to

prevent correct functioning

being impaired. It should be

possible to air the room to

ensure that the air remains dry

and no condensation forms

The TA 33clip has been manu-

factured for normal operating

conditions and is designed as a

table-top device.

Today’s furniture is coated with

a vast array of varnishes and

plastics and is treated with dif-

ferent polishes. This inevitably

means that there is a risk that

some of these substances may

contain components which

damage the rubber feet on the

TA 33clip. In this situation, it is

possible that the feet on the

unit damaged by external sub-

stances may leave unsightly

marks on the surface of furni-

ture. The manufacturer cannot

therefore accept any liability for

damage of this nature. Please

position the TA 33clip on a non-

slip base.

Connecting the Devices

Mounting and Commissioning

If you would prefer to mount

the device on a wall, the follow-

ing tools are required:

• 6 mm drill bit for stone (type

of drill depends on the mate-

rial)

• Drill

• Screwdriver (suitable for the

type of screw being used)

Warning

Ensure that there are no power

lines, cables or similar laid in

the area where you plan to drill

the holes.

To mount the TA 33clip onto

the wall, use the drilling tem-

plate supplied (see page 49) to

drill two holes approx. 30 mm

deep and insert two plastic

dowels with a diameter of 6

mm. Screw in the screws so that

the distance between the wall

and the screw head is approx.

4.5 mm. The screw shank

should be 3.5 mm thick. Hang

the TA 33clip up on the two

screws. The AC adapter

socket is located on the

underside of the TA 33clip.

Insert the plug of the AC

adapter cable into this socket.

However, do not plug the

adapter into the mains socket

at this point.

Connecting the

Devices

Connecting Analogue

Terminals

On the front of the device you

will find two RJ11 sockets for

analogue terminals.

Avoid using terminals with dif-

ferent dialling modes (pulse

dialling and DTMF) on the same

line (e.g. via an adapter cable).

For more information on this,

see “Setting the Dialling Mode”

on page 16.

Connecting the Devices

Please note

Pulse-dialling terminals must

be checked in using a specific

procedure in order to be

detected automatically (see

page 16).

Please do not use any connec-

tion cables longer than 3

metres for analogue terminals.

Connecting the TA

33clip to the ISDN

The TA33clip has a general con-

nection licence. This means that

anyone may connect the device

to the operator’s telephone net-

work, but only if the following

conditions are met:

• The device is only designed

for the ISDN basic access S

bus. Never connect the

device to lines or devices in

an analogue network. This

could result in malfunctions

and/or damage both to the

ISDN adapter and to the net-

work.

• The Euro-ISDN basic multi-

terminal access must be

equipped with a network ter-

minator (NTBA) from your

network operator.

You will find the ISDN connec-

tion socket for the ISDN connec-

tion cable supplied on the

underside of the device. Con-

nect this to the network termi-

nator (NTBA).

Connecting the TA

33clip to the Power

Supply

The connection to the 230-V

mains supply can only be car-

ried 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 TA

33clip does not have a sepa-

rate mains switch. The TA 33

clip 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 sup-

ply, always pull the adapter

itself out of the mains socket.

Caution!

Only use the AC adapter sup-

plied, part no. 4505617. Other

adapters can cause malfunc-

tions 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.

Connecting the Devices

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 dam-

age.

• 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 spe-

cialist dealer if the adapter

plug cable cannot reach a

socket.

Power Supply Socket

Telecommunications systems

can be affected by interference

from the power supply originat-

ing from other electrical

devices. This is a known issue

with photocopiers, laser print-

ers, electric typewriters, air con-

ditioning units, fan heaters,

vacuum cleaners and refrigera-

tors in particular. For this rea-

son, the following points must

be observed:

• Connect the TA 33clip 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

33clip.

• Ensure that the AC adapter is

safely and securely inserted

into the socket at all times.

Loose plugs and sockets rep-

resent 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 guar-

anteed for adapters with a

safety registration code dis-

played on the outside (e.g.

with the CE symbol, previ-

ously the GS symbol for

approved safety). Otherwise

malfunctions may occur

when operating the TA

33clip, including a risk of fire

in the event of a fault.

Note

Provide a separate power sup-

ply to the 230-V connection for

the TA 33clip. This excludes the

risk of short circuits from other

existing devices rendering the

TA 33clip non-operational.

To protect against surges,

which can occur during thun-

derstorms, it is advisable to

install a surge protection

device. Contact an electrician

for specialist advice.

Following correct assembly and

installation, connect the TA

33clip to the power supply. The

AC adapter socket is located on

the underside of the TA 33clip.

Insert the AC adapter cable plug

into this socket. Then plug the

adapter into the mains socket.

If the LED is continually illumi-

nated, the TA 33clip is con-

nected to the power supply.

In the event of an error, please

first attempt to rectify the fault

using the “Troubleshooting”

table.

Telephone

Numbers

Basics

As the TA 33clip is supplied as a

“plug & play” device, it is only

necessary to program it for spe-

cific purposes, e.g. if you want

to set up a fax machine with a

separate number on your TA

33clip. In the default setting, all

calls are signalled on both ana-

logue lines. Your ISDN access

normally includes three num-

bers (MSNs), but you can order

more from your provider.

Switching the

Programming Mode

on/off

Before you can carry out any

programming on the TA 33clip,

you need to switch the pro-

gramming mode on. This then

remains active for 15 minutes

before being switched off auto-

matically. You can also switch

the programming mode off

manually by entering a code.

Please note that whilst the pro-

gramming mode is active, no

outgoing or incoming calls are

possible on any of the terminals

connected to the TA 33clip.

Programming is carried out

using a DTMF telephone which

is plugged into one of the RJ11

sockets on the front. This tele-

phone is also used to switch the

programming mode on.

Connecting the Devices

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 hand-

set. 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 33clip will automatically

switch back to DTMF operating

mode. It is therefore advisable

to avoid using hand-held trans-

mitters or signal transmitters

for the remote querying of

answerphones on devices using

pulse dialling.

Programming Telephone Numbers

Programming the

Telephone Numbers for

the Analogue Lines

You can allocate telephone

numbers to each of the two

analogue lines. Calls for these

numbers are then signalled on

the terminals connected to the

respective analogue line, i.e. on

the terminals plugged into this

RJ11 socket. A maximum of

three telephone numbers (mak-

ing a total of six) can be pro-

grammed for each analogue

line. The telephone numbers

are assigned the codes “1,” “2”

and “3” for each line.

The lines are assigned the codes

“1” for line 1 and “2” for line 2.

Open out the front gatefold

page “Planning Your System”

and note down the relevant

numbers.

Programming the Telephone

Numbers for Analogue Line 1

Program the first number using

the following key sequence.

Lift the handset.

Press the code digit “1” for

line 1.

Press the programming

code digits (“1” and “2”).

Press the telephone num-

ber code digit.

Enter the telephone num-

ber (without your area

dialling code).

Press the hash key.

You will hear the acknowl-

edgement tone.

Replace the handset.

Telephone numbers can be up

to 12 digits long.

Programming Telephone Numbers

Switching the programming

mode off:

8 # q

Once you have switched the

programming mode on, you

start programming the individ-

ual numbers by lifting the

handset. After a few seconds

you will hear a series of very

short high-pitched tones (this is

the programming tone). Your

inputs have been saved once

you hear a low-pitched tone for

one second (positive acknowl-

edgement tone). Invalid inputs

are rejected with three short

high-pitched tones (negative

acknowledgement tone). You

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.

Note

To program the TA 33clip with-

out access to the ISDN, you will

need to wait for approx. five

seconds after replacing the

handset before following the

procedure described on pages

17 and 34.

Programming Telephone Numbers

Settings for Text

Messages (SMS)

If you are operating an SMS-

compatible telephone on your

access, a different telephone

number should be pro-

grammed for each line under

the telephone number code

digit “1” (see gatefold cover

page of this user guide). The

reason for this is to prevent the

second telephone ringing when

a text message is received. The

number display function (CLIP)

must not be switched off as

otherwise it is not possible to

send text messages.

Programming Telephone Numbers

If necessary, program a second

and third number for the line.

If you hear negative acknowl-

edgement tone, an error has

occurred during the input

process.

Please repeat the input.

If you want to delete a pro-

grammed telephone number,

enter the code digit for that

telephone number (“1,” “2” or

“3”) and then press the hash

key straight away.

Programming the Telephone

Numbers for Analogue Line 2

Program the first number using

the following key sequence.

Lift the handset.

Press the code digit “2” for

line 2.

Enter the programming

code digits (“1” and “2”).

Press the telephone num-

ber code digit.

Enter the telephone num-

ber (without your area

dialling code).

Press the hash key.

You will hear the acknowl-

edgement tone.

Replace the handset.

Telephone numbers can be up

to 12 digits long. If necessary,

program a second and third

number for the line.

If you want to delete a pro-

grammed telephone number,

enter the code digit for that

telephone number (“1,” “2” or

“3”) and then press the hash

key straight away.

Programming Telephone Numbers

Programming the example

configuration: analogue line 2

On the right-hand RJ11 socket

(analogue line 2) you want to

operate another analogue tele-

phone (e.g. cordless DECT tele-

Programming code digit

Telephone number code

digit

Telephone number

(“4711”)

Then switch the programming

mode off again (see page 18).

A maximum of six telephone

numbers can be programmed,

three for each line.

Other numbers can be used for

ISDN terminals (in the example,

a PC with an ISDN card) which

are connected directly to the

NTBA or the S

bus. Program-

ming here is then carried out on

the terminals themselves.

Note

In order for your network oper-

ator to provide billing for spe-

cific telephone numbers, the

telephone number used to

make a call is important. The

telephone number pro-

grammed under the code digit

“1” is always used for this pur-

pose. If no telephone number is

programmed under this digit,

the call will be billed under the

main number for your access.

Calls

Displaying the Caller’s

Number / Text

Messages (SMS)

This function is also known as

CLIP (Calling Line Identification

Presentation) and must be sup-

ported by your network opera-

tor. In addition, the number has

to be transmitted by the caller

and your terminals must be

equipped for this function. If

required, contact your network

operator to order the CLIP serv-

ice. The CLIP function is also

required if you want to receive

text messages (SMS) using suit-

able terminals.

External Calls

Lift the handset.

and dial the external

telephone number.

External calls can be made on

both analogue lines simultane-

ously. Incoming calls for all

numbers are signalled on both

lines unless you have pro-

grammed your TA 33clip differ-

ently. No charge pulses are sent

to the analogue terminals.

Note

During a call via DTMF sig-

nalling it is advisable to avoid

using hand-held transmitters

for the remote querying of

answerphones on devices using

pulse dialling. This will block

your device for any further

dialling and it will need to be

re-enabled by dialling any digit

other than “1” (see also page

16).

Internal Calls

You can make internal calls free

of charge between the two

telephones.

ISDN Features

If your inputs for setting the

features were successful, you

will hear the positive acknowl-

edgement tone (low-pitched

tone for one second). Invalid

inputs are rejected with the

negative acknowledgement

tone (three short high-pitched

tones). Certain inputs are

acknowledged with tones. A list

with descriptions of all the

tones and cadences can be

found in the appendix.

Temporary Calling Line

Identification

Restriction for a Call

The telephone number stored

under the telephone number

code digit “1” for the line used

to make the call is always trans-

mitted to the called subscriber.

You can temporarily restrict

calling line identification for a

call. This also applies to enquiry

calls made during this call. If you

want to set the calling line iden-

tification restriction perma-

For technical reasons it is not

possible to hold a three-party

conference with one external

subscriber and the other inter-

nal subscriber on the TA 33clip.

In a three-party conference the

second line on the TA 33clip is

not available; another terminal

on the TA 33clip cannot there-

fore make any calls.

Other terminals on the ISDN

access or internal S

bus on a

telephone system can make or

take calls on the second chan-

nel (B-channel).

Call Forwarding

You can forward calls intended

for you to a different telephone

number.

There are various different ways

of doing this. All call forwarding

options are set individually for

each line on the respective

terminal. There are three types

of call forwarding which can be

selected by entering the rele-

vant call forwarding (CF) code

digits.

• Immediate call forwarding

CF code digits “21”

• Call forwarding on busy

CF code digits “67”

• Call forwarding on no reply

CF code digits “61”

In order to use the call-forward-

ing function, your telephone

numbers must be programmed

for the respective analogue line

(see page 17ff).

ISDN Features

Callback on Busy

This function must be sup-

ported by the network opera-

tor, and ordered if necessary.

You have called an external

user. The line is busy and you

hear the special busy tone.

If you do not hear the special

busy tone, the callback on busy

option cannot be used.

Requesting callback on busy:

c q * 3 7 # q d

You will hear the positive

acknowledgement tone if the

callback request has been

accepted. As soon as the line

becomes free, your telephone

will ring.

When you lift the handset, the

previously busy subscriber is

called.

Programming Other Settings

(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.

Permanent Calling

Line Identification

Restriction

When you make an outgoing

call, your telephone number is

transmitted to the called termi-

nal, assuming that that terminal

supports calling number dis-

play. In the default setting, the

TA 33clip is configured to trans-

mit the telephone number. You

can permanently restrict or

enable transmission.

To restrict the transmission of

your own telephone number:

b t

(line code digit) and

8 0 1 q d

Line code digit: “0” for both

lines, “1” for line 1, “2” for line 2

Switching the

Programming Mode

on/off

Before you can carry out any

programming on the TA 33clip,

you need to switch the pro-

gramming mode on. This then

remains active for 15 minutes

before being switched off auto-

matically. You can also switch

the programming mode off

manually by entering a code.

Please note that whilst the pro-

gramming mode is active, no

outgoing or incoming calls are

possible on any terminals con-

nected to the TA 33clip.

Programming is carried out

using a DTMF telephone which

is plugged into one of the RJ11

sockets on the front. This tele-

phone is also used to switch on

the programming mode on.

Switching the programming

mode on:

you will hear a series of very

short high-pitched tones (pro-

gramming tone). Your inputs

have been saved once you hear

a low-pitched tone for one sec-

ond (positive acknowledge-

ment tone).

Invalid inputs are rejected with

three short high-pitched tones
