摘要：information transmission system, in particular telephone system, in whichsubscribers can be connected to a central line and a multiplexer or a
d\émultiplexeur in two-way (4, 4 ') is connected through a modem circuit (5, 5')bidirectionne the end of the line (6) corresponding to the center and the subscriber.thechannel modem (5, 5 ') module and demodulates the data according to the
transmission.the compression and decompression circuits for bidirectional (3, 3 ') areconnected to the multiplexers and demultiplexers (4, 4'), which are connected to thesubscriber circuit via a two-way analog to digital converters (2) or a switching installation(11; 11 ') of the central through control circuits (11, 12, 13).in another way, it may beexpected that at the end of the line (6) corresponding to the core and, on the other hand,the circuit is connected to a subscriber modem (5, 5 '), both which modulates anddemodulates the data according to the transmission circuit set, modem a circuit isconnected to a compression or decompression (17 217), which is connected to amultiplexer or a two-way d\émultiplexeur (18, 18 '), to which the subscribers areconnected through a bidirectional analog to digital converters (2) or a switching facility
(11; 11') through the channels of the central order (2; 12; 13).
