See "Capture".

Multiple Subscriber Number. The phone numbers belonging to a multiple ISDN 

connection. Each terminal is addressed separately, e.g., a separate number for a fax 

machine. Three MSN's are included in the basic price of a standard and added-

feature connection. Up to ten MSN's can be assigned to one ISDN connection.

ISDN connection which, unlike PABX connection, provides up to ten MSN's instead 

of having a direct dialling number block. This is the preferred type of ISDN 

connection for private customers.

See "MSN".

See "Waiting melody".

Convenience feature for telephones, which deactivates the built-in microphone (in 

handset or handsfree unit).

During a phone call you can enter a phone number in the phone's temporary 

memory to be dialled later.

Network terminating device (NT = Network Terminator and NTBA = Network 

Terminator Basic Access). The public T-ISDN is terminated with an NT. The NT acts as 

a bridge to the existing telephone outlet. Only the NT can or may be connected to 

the telephone outlet. Under no circumstances should analogue terminals also be 

connected to the phone outlet. ISDN terminals and additional ISDN outlets are 

connected to the NT.

At the touch of a key, all those present in a room can listen in to a phone call via an 

integrated loudspeaker. See also "Handsfree talking".

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.
