ABSTRACT:
A network termination (NT) which is universally applicable and permits fair billing. The network termination (NT) according to the invention is characterized in that it comprises a switching facility (DET,1, 2, 3) whereby the interface (a/b, U) on the network side is switchable from an analog one (a/b) to a digital one (U). A subscriber who needs a digital interface, for example because he wants to have two B channels of the ISDN at his free disposal, can release a digital interface (U) or have it released. A subscriber who wants only an analog access can release an analog access or have it released. To accomplish this, the network termination (NT) contains a switch (3) and a detector (DET). The switching between analog access and digital access on the network side can be effected without replacement of the network termination (NT).
