connection with one call director number block. This is the most commonly used
type of ISDN connection for private customers.

See "MSN"
Music on hold

Mute
Convenience feature for telephones, which deactivates the built-in microphone (in
handset or handsfree unit).
N
Notebook function
You can enter a phone number in the buffer memory of the telephone, so it can be
dialled later.
NT/NTBA (NT 2a/b)
Network terminating device (NT = Network Terminator or NTBA = Network Termina-
tor Basic Access). The public T-ISDN ends with the NT connection. The NT forms the
bridge to the existing phone outlet. Only the NT can and may be connected to the
phone outlet. Analogue end devices must not be connected to the ISDN phone out-
let. ISDN end devices and other ISDN outlets are connected to the NT. Analogue tele-
phones must be connected to the analogue connections (a/b port) on the NT 2 a/b.
O
Open listening
By pressing a button, everyone in the room can participate in a phone call via the
built-in loudspeaker. See also "handsfree talking".
Outgoing MSN, freely selectable
A performance feature which helps you to individually determine which MSN should
be used for the following call. This is not only important for the phone number
display on the called handset but also for billing charges. This is because call
charges, which can be broken down free of charge according to MSN on the network
provider invoice, are billed according to the MSN used to make the call.
P
Parking
A call is parked when you want to unplug the telephone during a call, or you want
to continue your call from another telephone with the same connection. The
connection is retained while it is parked.
PIN
Abbreviation for Personal Identification Number. It is used as protection again
unauthorised use, such as system PIN, answering machine PIN, handset PIN.
