Features
TELES.iPBX 8TR Box
iPBX stands for intelligent Private Branch EXchange. The TELES.iPBX 8TR
Box features eight TR ports for connecting analog terminal devices to ISDN.
You can make use of the advantages offered by ISDN without having to give up
your conventional analog devices. And that’s not all: The small box provides all
the important features of a large PBX.
The TELES.iPBX 8TR Box is a TELES.Family member. Thanks to the paten-
ted TELES-Family concept that opens unique possibilities for the combination
with other TELES-ISDN devices this box offers further smart solutions with
even more power and comfort.
1 Features
• ISDN PBX for point-to-point or point-to-multipoint lines.
• The TELES.iPBX 8TR Box is suited for all analog terminal devices (tele-
phones, faxes, answering machines, etc.). Three devices can be attached to
each port, making the operation of up to 24 terminal device possible.
• Eight analog terminal devices can be run simultaneously. Up to two simulta-
neous connections to the public network are possible.
• Several boxes or further ISDN terminal devices, e.g. a PC/ISDN adapter, can
be attached to an ISDN point-to-multipoint line.
• All functions are set by a telephone that supports touch-tone dialing - but
much simpler via PC when connected to a PC with a TELES.ISDN board and
TELES.OnlinePowerPack (see following page and section 8, page 58).
• The box supports the ISDN protocol DSS1 and is therefore suited for Euro-
ISDN ports.
• You can set your own call numbers for any port. Up to 10 multiple subscriber
numbers (MSN) can be programmed.
• Operation and active connections shown by LEDs.
• Cost-free internal connections between terminal devices attached to the box.
• Holding and transferring using the R key between internal and external par-
ties.
• Comfortable call transfer – a special feature that is only offered by TELES:
you can profit from using further TELES.ISDN devices besides the
 2004 by TELES AG Berlin, Version 2.0/iPBX8TRe/6.02, Issue: May 1998 Page 1

Features
TELES.iPBX 8TR Box on the same ISDN line such as the ISDN telephone
TELES.FON. You can transfer calls then, for example, at no cost to or from
one telephone on the box to the TELES.FON. When using other manufactur-
ers’ devices, this is only possible by complicated parking and then retrieving
from the other extension.
• Three-party conference – simultaneous telephoning among three parties.
• Callback on busy – connection is established once the desired party is no
longer busy.
• Call forwarding – whether the ISDN line supports it or not. You can set a port
of the box or an external extension as destination.
• Incoming calls can be distributed among the ports by night services or by the
‘distribute incoming calls’ function.
• The selection of different telephone companies for economical telephoning
can be simplified using the TELES.iPBX 8TR Box by storing your favorite
network carrier. Furthermore, the box supports “Direct Line Access with
Subaddressing”. A connection is established to a dial-in node that can deter-
mine a lower priced connection rate. In both cases, you can determine which
connections should be handled by this carrier.
• To display the charge on analog terminal devices the TELES.iPBX 8TR Box
supports the metering pulse (16 kHz) per charge unit.
• Using charge accounts for the ports, you keep control over your telephone
bills. If the charge account is depleted a block is activated.
• Besides that, you can set different block types in order to prevent expensive
connections. Emergency numbers can always be dialed of course.
• Using direct call, a connection to a stored telephone number is automatically
established when the receiver is lifted – simplest handling for small children
who cannot dial a number yet.
• Do-not-disturb: By setting a block against incoming calls, you avoid interrup-
tions by calls. You can work in peace.
• As you conduct a telephone conversation, the call waiting beep announces a
further incoming call. You can switch this function on and off as needed.
• By setting the wake-up call function, you can have the telephone ring at a pre-
set time.
• Play on-hold music from an external audio source for held connections.
Page 2  2004 by TELES AG Berlin, Version 2.0/iPBX8TRe/6.02, Issue: May 1998

Features
• External and internal calls or Callback on busy can be identified by different
ring tones
• You can store up to 100 centrally stored speed dial numbers for frequently
called parties.
• A PIN for all important functions protects your box against unauthorized
changes of settings.
• Some functions can be controlled by remote administration. You can, for ex-
ample, switch a call forwarding remotely. This way you are always reachable
when away and will miss no call.
TELES.Family Concept: Patent solution for even more convenience
• An additional TELES.BRI board with appropriate software, the all-in-one-
ISDN/Multimedia TELES.OnlinePowerPack, provides even more conven-
ience. You can easily program almost all functions of the TELES.iPBX 8TR
Box from the monitor. Numerous further functions are available, for example,
comprehensive statistics with connections and charge meter and call number
identification for incoming calls. This is only possible though for point-to-
multipoint line where several terminal devices can be attached. If you have a
point-to-point line then you can attach only one ISDN device to it.
• You can enjoy all the benefits of PC-integrated telephony: electronic phone-
book, convenient automatic dialing by mouse click, integrated answering ma-
chine.
• The TELES.OnlinePowerPack is a suite of over 20 ISDN communications
applications. It contains programs and interfaces for Internet access, file trans-
fer, fax for Windows programs, videoconferences, application sharing, mo-
dem emulation including V.34, follow-me service by the electronic secretary,
etc.

3 Installation
This chapter describes how to attach and configure your the TELES.iPBX 8TR
Box. The following basic steps are necessary for the installation:
1. Attach power source (section 3.1.1).
2. Connect the analog terminal devices to the TR ports (section 3.1.2).
3. Connect TELES.iPBX 8TR Box to ISDN (section 3.1.3).
4. Only for point-to-point line: change line type from the point-to-multipoint
factory setting to point-to-point (section 5.2)
Once you’ve taken these steps the box is operable and you can start making calls
right away. All incoming calls will ring at port 11 (drop port) though. Continue
then with the following settings:
5. Assign the call numbers of your ISDN line (MSN) to the individual ports
(section 3.2.2).
6. Check if you can hold and transfer with the attached telephones. Adapt the R
key’s flash time if necessary (section 3.2.1)
Now you can accept calls at the individual ports, and hold and transfer them.
The correct telephone number is transmitted. Next, you can adapt the
TELES.iPBX 8TR Box to special needs (e.g. different ring tones for internal and
external calls, PIN setting, external audio source, etc.).

ing of the LEDs. The test takes a few seconds. Following the error free proce-
dure, only the red power LED remains lit.
3.1.2 Attaching Analog Terminal Devices
Attach the terminal devices to the TR
ports on the box’s rear side. Clips in
the ports hold the wires of the cables.
The figure shows how to use a screw-
driver to attach the wires.
In case the cable of your terminal de-
vice has four wires, refer to the de-
vice’s documentation in order to find out which wires are the active ones.
1) Press a screwdriver
into the upper slot.
2) Press the wire into

wire
Lift the receiver and check if the LED for that port lights up. You should also
hear the dial tone. You can attach a maximum of three terminal devices to each
TR port.
The cable from the TR port to the terminal device should not be more than 50
meters long.
3.1.3 Attaching to ISDN
Attach the TELES.iPBX 8TR Box to the ISDN socket (NT) using the ISDN ca-
ble included (wide RJ-45 plugs at each end). If you use a point-to-multipoint
line, you can attach several ISDN terminal devices.
Note: Your TELES.iPBX 8TR Box is now ready for operation. If this
is not the case, please check the notes in section 5.2 page 36.

3.2 Setting TELES.iPBX 8TR Box
The TELES.iPBX 8TR Box is set via a DTMF/“touch tone”- telephone (DTMF
= Dual Tone Multi Frequency) attached to any port of the box. Refer to user’s
manual of your telephone how to change the dialing method if necessary. As an
alternative, you can also use the device to query the answering machine re-
motely.
The ∗and #-keys: Both keys have to exist on the telephone. All commands start
with ∗and end with #.
Confirmation tone: As soon as you’ve entered a command and the function
was activated, you hear two short consecutive tones (see manual cover).
Error tone: If the function could not be activated or you’ve pressed the wrong
key, you will hear the busy signal – the error tone (see manual cover).
Remote administration: Remote administration is not possible until the dial-in
call number for remote access has been set (section 6, page 51).
PC-integrated control: Besides using a telephone for configuration, you can
also make settings using a user-friendly Windows software. All you need is an
ISDN board for your PC – e.g. a TELES.BRI board with the
TELES.OnlinePowerPack application suite. This board should be attached to the
same ISDN line as the TELES.iPBX 8TR Box (see section 8, page 58). This is
only possible on point-to-multipoint lines.
3.2.1 Hookflash Time of the R key
As in any PBX, the hold, the transfer as well as the hold and alternate functions
are also initiated in the TELES.iPBX 8TR Box by a signal that is sent to the box
when you press the R key on the telephone.
Attached analog telephones must feature such a key. The key is also known as
signal or hookflash key.
ΡThe hookflash time of the TELES.iPBX 8TR Box is 90 - 300 ms.
Please adjust the key to hookflash for the specified time according to
the telephone’s manual. The usual “ground” setting on older tele-
phones is not supported. The functions mentioned above will not work
if there is a deviation.

3.2.2 Port Numbers
To make a call from one extension of the TELES.iPBX 8TR Box to another, all
you need to do is dial the port number.
Port numbers frequently also have to be entered when setting functions, e.g.
when you set call forwarding, make a block or change the ring tones for individ-
ual ports, etc.
The box’s eight ports are numbered as following:
Extension Internal port number
1 11
2 12
3 13
4 14
5 15
6 16
7 17
8 18

3.2.3 Call Numbers (MSN) of Ports
Note: By default, no call number is set. All calls for your ISDN line’s
telephone numbers will arrive therefore on port 1; the so-called
drop port (section 5.13, page 47
If you assign a unique call number to each TR port, only the attached device will
answer calls sent to that number. You will find the call numbers available for
your ISDN line in the documents provided by your ISDN carrier. For point-to-
multipoint lines, you may receive three or more MSNs (depending on country
and carrier). These MSNs (= Multiple Subscriber Numbers) are your complete
call numbers without prefixes. Up to 10 MSNs are programmable in the box.
Assign a call number to a TR port:
Υ Lift the receiver. You hear the dial tone.
∗ Press the star key.
Π Enter the PIN. By default, no PIN is set. If no PIN is set, you do
not need to enter anything.
041 Enter the digits 041.
Ν Enter the port number: e.g. 11 for the first port 1, 12 for second
port, 13 for the third port, etc. (see above)
Ν Enter the appropriate MSN.
# Press the pound key.
∆ Listen for the confirmation tone. Put the receiver down.
Example: You have been assigned, for example, the MSNs 39928312,
39928313 and 39928314. Port 11 should be reached by the first
MSN, i.e. the call number 39928312.
∗(Π) 041 11 39928312#
Note: You may enter each MSN only once. Would you like to have
several ports accept calls for one MSN use the distribute calls
function (section 4.6.1 or 9.2).
Delete: Single MSN on the port: ∗(Π)040 MSN#.
All MSNs of the box: ∗(Π)0400#

Operation
4 Operation
This section describes how to operate terminal devices, usually telephones, on
the TELES.iPBX 8TR Box. In order to handle your telephone effectively, you’ll
need your telephone’s user manual as well.
4.1 Introduction
Undoubtedly, you are already familiar with telephone systems (PBXs) and know
that you can conduct conversations within the PBX and call into the public net
via the outside line access. You probably also know that you can transfer calls
within a PBX and can switch back and forth between different parties (hold and
alternate).
However, the TELES.iPBX 8TR Box also offers a series of further useful func-
tions that will enhance your daily handling of the telephone:
• From your own phone you can pick up calls to other extensions – no need to
run to the appropriate telephone anymore.
• During a conversation, you can hear if a further party is trying to reach you
(call waiting). You can accept the new connection and then hold and alternate
between both calls.
• You can forward calls directed to your extension to another telephone when
you’re away from your desk.
• You can switch off your telephone when you do not want to be disturbed
(block against incoming calls).
• ... and much more.
