ABSTRACT:
System for establishing a permanent connection between the Internet and a user subscribed to it. There, a switching PoP (4) is used in which in addition to the incoming lines (1) through which switched telephone traffic enters, there are lines (?) which are not connected to the telephone exchange (3) and are permanently connected to a connection at a subscriber. The inputs (7) of the PoP (4) not being connected to the telephone exchange (3) are executed as two-wire connections in such a way that the subscriber is directly connected to the PoP (4), One can also use standard multiplexing equipment (6), to which the subscriber is connected through a two-wire connection, said equipment being connected to said switching PoP (4) and is switched on the basis of an instruction from the PoP manager (8).
