Abstract

The network terminal unit is provided for digital and/or analog terminals (TE) provided with special function keys, which are to be connected to the U interface (U-SST) of an ISDN telecommunication network via a first bus system (IOM2) and an echo compensation circuit (IEC). The first bus system (IOM2) is connected to a coupling network (MTS). The latter is connected to a processor (MC) via a second bus system (PB). Further, the coupling network (MTS) can be connected to the digital or analog terminal (TE) via at least one further bus system (SB), KEB), via an S interface circuit (SBCX), an interface circuit (IPN) and/or an ab interface circuit (LIF1a, LIF2a). A conference module (CONF) for forming conference links and controlled by the processor (MC) may be connected to the coupling network (MTS). The ab interface circuit (LIF1a, LIF2a) preferably has a line circuit (SLIC) and a convertor circuit (COFI). The B channel can be switched through by the communication control (ICC) and the processor (MC) should be suitable for analysing and adjusting the D channel signalling data for the interface circuit. <IMAGE>
