Glossary
Services
A service identification (ID) (e.g. telephony, fax) is
transmitted in ISDN when an ISDN subscriber is
called. The caller is only connected if the called
terminal has the same service ID. This prevents
wrong connections of two different terminal types
(e.g. phone and fax).
DT - network
With the Microsoft Windows data transmission
network your computer can accept a connection
to an internet service provider.
Terminals
Appliances which you connect as internal
subscribers of the telecommunications system.
Analog terminals such as telephones, answering
machines, fax machines, combi-devices
(telephone, fax and possibly answering machine in
one unit), modem.
External
A distinction is made between internal and
external calls when telephoning in a
telecommunications system. External calls are
calls to subscribers which are not connected to
your telecommunications system. Connections
between terminals of your telecommunications
system and other terminals at your multi-
equipment access are therefore also external
connections. The local tariff is usually charged for
such connections.
External seizure (seize outside line)
Seizure of a line (B-channel) to call an external
subscriber.
Outgoing external connection
Connection to an external subscriber set up from
a terminal of the telecommunications system by
dialling an external phone number.
Pulse dialling method (PD)
Every dialled digit is assigned a fixed number of
pauses. The pauses are audible in the earphone
when dialling.
Internal
Internal calls are calls which subscribers in the
telecommunication system hold with each other
by dialling the internal phone number. These calls
are generally free.
ISDN (Integrated Services Digital Network)
All services (speech and data) can now be
transmitted in one network.
Incoming external connection
Connection to a terminal of the
telecommunications system set up by an external
subscriber with the phone number of the
telecommunications system.
Configuration
Setting (programming) the functions of the
telecommunications system with a PC by means
of a configuration program.
Line (B-channel/S0 basic access)
You can connect an external S0 basic access to
your ISDN telecommunications system. Every
external S0 basic access behaves like two
conventional analog lines. You therefore have two
lines (B-channels) on which you can make
telephone calls (local, long distance or overseas
calls).
Dual tone multi-frequency dialling method
(DTMF)
Every dialled digit is assigned a certain tone.
Telephones with this dialling method require a
signal key (refer back key R) on the
telecommunications system.
MoH (Music on Hold)
A waiting external subscriber hears music whilst
the connection is on hold, e.g. when a call is
forwarded.
MSN (Multiple Subscriber Number)
The multiple subscriber number is one of the
phone numbers under which the multi-equipment
access can be reached.
NTBA (Network Termination for ISDN Basic
Access)
The network operator lays his copper cables up to
this access point (S0 basic access). You connect
your telecommunications system and other ISDN
terminals to it.
Ringing assignment
In the ringing assignment you define which
terminals of the telecommunications system are
to ring when an external call is received. Should
only one terminal ring or several terminals
simultaneously?
