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 ter-
minal has the same service ID. This prevents wrong
connections of two different terminal types (e.g.
phone and fax).
Terminals
Appliances which you connect as internal subscrib-
ers 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 dial-
ling 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 transmit-
ted in one network.
Incoming external connection
Connection to a terminal of the telecommunica-
tions system set up by an external subscriber with
the phone number of the telecommunications
system.
Configuration
Setting (programming) the functions of the tel-
ecommunications 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 exter-
nal S0 basic access behaves like two conventional
analog lines. You therefore have two lines (B-chan-
nels) 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 telecommunica-
tions system.
MoH (Music on Hold)
A waiting external subscriber hears music whilst the
connection is on hold, e.g. when a call is for-
warded.
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 termi-
nals of the telecommunications system are to ring
when an external call is received. Should only one
terminal ring or several terminals simultaneously?
Ringing assignments for external calls are: day
service, night service and forwarding (internal).
You can switch over between day and night service
at any time from any telephone.
