Configuring
Setting (programming) the telephone
system's functions from a PC using a
configuration program.
Dual tone multifrequency dialling
(DTMF)
Every dialled digit is assigned a specific tone.
Telephones that operate on the basis of this
dialling method require a signal key (inquiry
key R)/flash function on the telephone
system.
MoH (music on hold)
A waiting external subscriber hears music on
hold while the connection is placed on hold,
e.g. a call is being forwarded.
MSN (Multiple Subscriber Number)
A multiple subscriber number is an ISDN
phone number for a point-to-multipoint
connection. In Germany, for example,
Deutsche Telekom provides three multiple
subscriber numbers free of charge for your
telephone system.
NTBA (Network Termination for ISDN
Basic Access)
The telephone company lays its copper
cables up to this access point (S0 basic
access). Here, you connect the telephone
system via a point-to-point or a point-to-
multipoint connection.
Ringing distribution
In the ringing distribution settings, you
define which terminals of the telephone
system are to ring in the event of a call. Is
only one terminal to ring or are several
terminals to ring at the same time?
Ringing distribution settings for calls from
the outside are:
Call variant 1 (day time service), call variant
2 (night service) and call variant 3 (call
forwarding).
Ringing distributions for calls from the door
(door hands free unit TFE): door call variant
1 (day) und door call variant 2 (night).

Call forwarding
A call from an external location that has not
been accepted within a specific time is
forwarded. The terminals of the telephone
system that are defined in the call
forwarding settings then ring. The time up
to call forwarding can be set.
Switching box
You can call up your telephone system's
switching box from an external location and,
by post-dialling a code, you can switch the
relays of your telephone, you can switch the
call variants, you can set up a diversion or
you can monitor a room, for example. From
an external location, you reach the switch-
ing box on a point-to-point connection by
means of a direct dialling in number or, on a
point-to-multipoint connection, by dialling a
separately assigned multiple subscriber
number (MSN). With the switching box
code, you can protect the switching box
against unauthorised access.
Signal key R (inquiry)
This is a key on the telephone that you must
press if you with to inquire with another
user during a conversation. The signal key
must have a flash function, i.e. it must
produce a brief interruption
(AS 140 to AS 191: 70 ... 120 ms,
AS 31 ST, AS 32: 50 ... 150 ms)
Door hands free unit
This is a door station with a bell button and
a door opener that you can connect to the
telephone system. From the telephone, you
can speak with a visitor at the door and you
can open the door.
Outside line (B channel/S0 basic access)
You can connect an external S0 basic access
to your ISDN telephone system. Every
external S0 basic access behaves like two
conventional analog outside lines.
Therefore, you have two outside lines (B
channels) on which you can make external
calls (local, long-distance or international
calls).
