FIELD: information technologies.
SUBSTANCE: data transfer unit (DUG) for transfer and reception of data into a network of communication line switching or from a network with communication line switching (LVN) comprises controlled switching facilities (USM), which are controlled so that the terminal data device (DEG) for transfer and reception of data into a network with communication line switching or from a network with communication line switching (LVN), which in the first mode of operation is connected through a data transfer device (DUG) with a network of communication line switching (LVN), may switch from the first mode of operation into the second mode of operation, in which the terminal data device (DEG) through a data transfer device (DUG), and also through a data processing device (DVG) for automatic processing of data and for transfer and reception of data into a network with switching of packets or from a network with packet switching (PVN), is joined with a network of packet switching (PYN), and vice versa.
EFFECT: making it possible to eliminate logical separation between applications, which are based on a network with communication line switching, and applications based on a network with packet switching.
