The telephone system has a general connec-
tion permit (Germany: AAE).
The telephone system is intended for con-
nection to an ISDN basic access (DSS 1). You
may connect all analog terminals to the ana-
log user ports of the telephone system that
you are also permitted to operate on the
analog telecommunications network.
You may connect all DSS 1 ISDN terminals

- The telephone system conforms
to the prescribed conformity
and safety regulations.
- Attention! The telephone sys-
tem must be electrically
earthed. Therefore connect the
Euro PE contact plug of the
power cable only to an expertly
installed socket (PE socket) to
prevent danger to persons and
material.
- Before connecting the sub-
scriber lines to the subscribers
and the ISDN network, pull out
the 230 V mains plug to switch
off the telephone system. Mor-
tal danger!
- Protective measure! Touch the
metal shield of the PC/printer
socket of the telephone system
briely with your finger. This will
discharge any possible electro-
static charges, thus protecting
the telephone system's electro-
statically sensitive components.
- You must not connect and dis-
connect subscriber lines during
a thunderstorm.
- Lay subscriber lines in such a
way that no-one can step on
them or stumble over them.
- Prevent the ingress of liquid into
the telephone system as other-
wise short-circuits may occur.
- No liability can be assumed for
consequential damages such as
the cost of an unintentionally
continued connection.
- The telephone system is out of
operation whenever power fail-
ures occur. You cannot make
telephone calls in such cases.

You may connect all approved analog ter-
minals to the analog parts of your tel-
ephone system that you are also permitted
to operate on the public telecommunication
network. These may be normal telephones
(a/b telephones), answering machines,
group 2 and 3 fax machines and analog
modems, for instance.
The dialling method employed by the ana-
log terminals may consist of the pulse dial-
ling method or of the dual tone
multifrequency method (DTMF). DTMF is the
faster dialling method. The telephone sys-
tem detects the respective dialling method
automatically.
From an analog terminal, you can reach any
internal user free of charge by dialling the
appropriate internal phone number. You
reach an external subscriber after seizing a
dial-up line (B channel) by dialling the ex-
change code 0and the external phone
number.
If you set "spontaneous exchange line
seizure with internal" for your telephone,
you must press the Rkey (hash key) before
the internal phone number. Internal dialling
is not possible on telephones, particularly
telephones using the pulse dialling method,
that do not have a Rkey or which do not
support these functions.
You operate the functions of the telephone
system by pressing the Skey (star key) and
by dialling a code digit. On telephones, par-
ticularly telephones that use the pulse dial-
ling method that do not have a Skey or
which do not support these functions, you
must press the digits 99 instead of the
Skey.
Please note: for the "inquiry" function,
standard analog telephones using DTMF
must have a signal key (inquiry key r)
with the flash function.
This instruction manual always specifies the
operating steps for standard analog tel-
ephones set to DTMF. On standard analog
telephones set to pulse dialling, you do not
need to press the rkey when making an
inquiry.
You can also use the functions of a standard
analog telephone (e.g. redial, abbreviated
dialling) in conjunction with your telephone
system. Please refer to the operating instruc-
tions for the telephone concerned for details
of these functions.
Details of how to operate the functions of
your telephone system that you are able to
use from a standard analog telephone set to
DTMF are given in this instruction manual
and in the "short-form operating instruc-
tions for analog and ISDN terminals".
When operating your telephone system, pay
attention to its audible signals. You hear the
acknowledgement tone when you have
successfully completed a code digit proce-
dure. Otherwise, you will hear the error
tone.
AS 40: The telephone system communicates
the counting pulses to analog terminals
featuring a display of connection charges
(charge pulses).
For data transfer via the analog ports, the
telephone system supports the V.90 stand-
ard (up to 56600 bps, reduction possible by
transmission path and cables to 33600 bps
V.34+). When operating a modem, it is
imperative to configure the modem to blind
dialling because most modems do not
detect the dial tone of a telephone system.
On modems that operate with the Hayes
command set, blind dialling is set by means
of the X0..X4 parameters.

You may connect up to eight ISDN terminals
to one internal S0 access of the telephone
system.
ISDN terminals:
- AGFEO system telephones digital
- ISDN telephones
- ISDN cards
- ISDN fax machines
Depending on current consumption, you
may connect at least four ISDN terminals
that do not have a power supply of their
own.
Example: 4 ISDN telephones or 2 system
telephones digital and 2 ISDN telephones.
All ISDN terminals must be approved ISDN
terminals (DSS 1).
The internal S0 access behaves like a point-
to-multipoint connection to which you may
assign any chosen internal phone numbers
of the telephone system. The two-digit
internal phone numbers are the multiple
subscriber numbers. You enter one or
several of these multiple subscriber numbers
(internal phone numbers) in your ISDN
terminal. In doing so, pay attention to the
ISDN terminal’s operating instructions. The
multiple subscriber number is this ISDN
terminal’s internal and direct inward dialling
number.
From an ISDN terminal, you reach any inter-
nal user free of charge by dialling the corre-
sponding internal phone number. After seiz-
ing a dial-up line (B channel), you reach an
external subscriber by dialling the exchange
code 0and the external phone number.
If you set "spontaneous exchange line
seizure with internal" for your ISDN
terminal, when dialling an internal number
you must press the Rkey (hash key) before
dialling the internal number. Internal dialling
is not possible on terminals that do not have
a Rkey or which do not support these
functions.
On an ISDN telephone, you operate the
functions of the telephone system in the
same way as on a standard analog terminal.
You execute a function after pressing the S
key (star key) and dialling a code digit.
On ISDN telephones that do not have a S
key or which do not support these
functions, you must enter the digits 99
instead of pressing Skey.
For an "inquiry" there must be an inquiry
key ron the ISDN telephone.
When operating your telephone system, pay
attention to its audible signals. You hear the
acknowledgement tone when you have
successfully completed a code procedure.
Otherwise, you hear the error tone.
The following are displayed to you on your
ISDN telephone:
- Caller’s phone number (internal and
external)
- Connection charges
- Date and time after the first internal
connection
You can only make restricted use of the
menu-prompted functions of your
telephone system for operating the ISDN
features.

Among other things, the TK-Soft software
package contains the TK-Phone CTI applica-
tion. It offers you the possibility of dialing
telephone numbers directly from a PC, of
viewing calls on your monitor during your
daily work and of dialing the numbers per-
taining to unanswered calls from a call list.

Contrary to TK-Phone, the TAPI (Telephony
Applications Programming Interface) is not
an independent CTI application, but an in-
terface between a TAPI-compatible Win-
dows application and the telecommunica-
tions system. If programs (applications) sup-
port this interface, you can use them to con-
trol the telecommunications system. The
scope of control depends on the application
you are using. However, in most cases it em-
braces starting of outgoing calls (dialing out
of the application) and displaying incoming
calls.

The TAPI is an interface of Microsoft operat-
ing systems and the application end of
Microsoft’s telephony interface. A telephony
service provider (TSP) from the manufacturer
of the ISDN hardware - in this case from
AGFEO - is needed to link this interface to
the AGFEO telecommunications system. The
TSP is a driver that you must install on your
PC. It executes the TAPI functions and con-
trols the necessary exchange of data be-
tween the PC and the telecommunications
system.
Owing to the constantly growing scope of
functions of applications that support TAPI,
the TSP is undergoing constant expansion.
We provide the TSP free of charge on our
Internet home page http://www.agfeo.de to
ensure that you always have the current TSP
for your needs.
The self-extracting file contains all informa-
tion needed for installation and relating to
the supported applications. If you do not
have an Internet access, contact your spe-
cialist dealer.

Making telephone calls
On your telephone, you can set the outside
line seizure "0" variant or the
spontaneous outside line seizure with
internal variant to seize an outside line (to
seize a B-channel).
Outside line seizure "0" variant
("as-delivered" setting): after picking up
the receiver, you hear the internal dial tone.
If you wish to call an external subscriber, dial
"0" to seize an outside line. When you wish
to call an internal user or initiate a proce-
dure, enter the internal phone number or a
code.
Spontaneous outside line seizure with
internal variant: after picking up the
receiver, you hear the telephone system’s
external dial tone. If you wish to call an
external subscriber, simply enter the external
phone number. The outside line is seized au-
tomatically. If you wish to call an internal
user, you must predial R.
Spontaneous outside line seizure
variant: this variant can only be set by
means of the PC configurator. It is suitable
for terminals that only operate external
connections, e.g. a fax machine or a
modem. When you pick up the receiver, you
hear the dial tone of the exchange. The
outside line is seized directly. Enter the
external phone number. In this variant, you
fcall any internal users and you cannot initi-
ate any procedures.
Every internal user of your telephone system
can be assigned two different two-digit
internal phone numbers (first and second
internal phone numbers) by programming. If
necessary, inquire which internal phone
numbers have been assigned to which users.

Outside line seizure on the combination
port – After the code "10" has been
dialled on the combination port (instead of
"0") , the telephone system also seizes an
outside line. However, it assigns the fax
service to the connection. When an outside
line is seized by dialling"0", the telephone
service is assigned.
Communicating your phone number – In
the case of outside line seizure with “0“ the
external phone number of the telephone
system assigned to you (system phone
number or multiple subscriber number, MSN
is sent to the ISDN exchange. The
connection costs are then recorded under
this phone number.
This phone number is also transferred to a
called ISDN subscriber providing that
communication of your phone number is
released.
How to account the connection costs under
another MSN, see under "Outside line

Outsidse line access (external access)
If, when seizing an outside line, you hear
the error tone instead of the external dial
tone, this means that your telephone has no
external phone number dial access.
Barred range - If the telephone system’s
barred range is programmed for your tel-
ephone, this means that you cannot dial the
external phone numbers that lie within the
barred range. You hear the error tone.
Internal call - Internal dialling is not possi-
ble on telephones for which spontaneous
outside line seizure with internal is set and
which do not have a Rkey (hash key) or
which do not support this key.
DTMF post-dialling is possible for all exist-
ing external connections, even in an inquiry
when brokering and during a three-party
conference. You can post-dial digits and
symbols (1...0, Sand R) .
You can agree two different code calls with
internal users of radio cells (base stations
with cordless telephones. The connection
must be programmed as a "radio cell").
When you dial the radio cell with the first
internal phone number, all users of the radio
cell are called with the tone ringing se-
quence of code call 1. When you dial using
the second internal phone number, they are
called with code call 2. The first user of the
radio cell who picks up the receiver is con-
nected to you.
Reserving an outside line - The telephone
system rings you for 60 seconds when the
reserved outside line is free. The reservation
is cleared after one minute if no connection
comes into being.
If you hear the error tone after reserving,
this means that the outside line is already
reserved.
On telephones that do not feature or do not
support a Skey (star key), you must press
the digits 99 instead of the Skey.

If you hear the busy tone after seizing an
outside line (e.g. by dialling "0"), this means
that both outside lines are busy. You can
reserve an outside line for yourself. As soon
as an outside line is free, the telephone
system will call you. When you pick up the
receiver, you hear the external dial tone and
you can enter the external phone number.

Accepting calls
Thanks to different ringing rhythms on your
telephone, you can distinguish between in-
ternal calls, code calls, door calls and external
calls provided your terminal supports the
different ringing rhythms.
When your telephone rings and you pick up
the receiver, you are connected to the caller.
You can end the call at any time by replacing
the receiver.
Call waiting announcement - You receive
a call while you are already making a call. The
waiting call is announced. You hear the inter-
nal call waiting announcement tone once
(internal call) or you hear the external call
waiting announcement tone several times
(external call). You can accept the call and
you can broker between both calls.
You can reject an external waiting call. When
you reject the waiting caller, the caller hears
the busy tone.

Forwarding a call
You can forward an external call to another
internal user or to an external subscriber.
Two kinds of internal forwarding are possi-
ble.
Internal forwarding with announcement
You call the internal user in an inquiry, you
announce the external call and you replace
the receiver. You have now forwarded the
external call.
Internal forwarding without
announcement
You call up the internal user in an inquiry
and you replace the receiver without speak-
ing with the internal user. The internal user
hears call ringing, and is connected to the
external subscriber after lifting the receiver.
External forwarding is only possible with
an announcement. You call the external
subscriber in an inquiry and you announce
the other external call. You forward the call
by dialling the appropriate call.

When forwarding an external call, you
must always seize the outside line by
entering "0", even if spontaneous outside
line seizure with internal is set on the
telephone.
External forwarding is only possible if a dial-
up line (B-channel) is free.
You bear the cost of the externally for-
warded call.
A user on the internal S0 bus can only for-
ward an external call internally if the second
B channel of the internal S0 bus is free. Ex-
ternal/external forwarding is not possible.
Internal forwarding with announcement
If the internal user does not answer, you are
connected back to the external subscriber
after dialling r0 . If necessary, you can
forward this external subscriber to another
internal user.
During the inquiry, the external subscriber
on hold hears a tune if you have internally
activated music on hold (MoH) or if music
on hold is fed in from an external source.
After internal forwarding without an-
nouncement, you receive a call back after
45 seconds if the internal user has not ac-
cepted the forwarded call within this time. If
you accept the call back, you are again con-
nected to the external subscriber. Ringing is
aborted after 60 seconds if you do not ac-
cept the call back.

Call waiting announcement / Callback / Call list
By means of Call waiting announcement,
you can make yourself noticeable to a busy
internal user. You hear the internal call wait-
ing tone. In his call, the other user hears the
internal call waiting tone. Your required call
partner receives your call immediately after
hanging up.
If he does not accept your call, you initiate a
callback when you replace the receiver.
You receive the automatic callback as soon
as the other user is free again. Your tel-
ephone rings. You only need to pick up the
receiver and the other user will be called au-
tomatically.
If you call an internal user who has a system
telephone that is free but who is not an-
swering, you can enter yourself in the call
list of this user’s system telephone.
