Interface Types 

  9 

Version 2.02 – 01.04 

 

 

Several interface types are available for Euro ISDN. 

 

ISDN TAs can only establish data connections to the following remote terminals: 
•  ISDN TA 
•  GSM data adapter, e.g. INSYS GSM 
A data connection to a purely analog modem is not possible. 

 

The basic rate interface is provided via a usual two-wire line with the switching center. 
The interconnection point between switching center and the customer is the network 
termination (NT). This is also referred to as NTBA / NT. A four-wire line, the S0 bus, 
connects the terminal devices to the NT.
