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).
