(57) Abstract: A communication system comprising: a plurality of subscribers having a telephone set and various types of home modems connected using a twisted pair to a local server having a plurality of downstream repeaters; and a subscriber line of the twisted pair. A central office connected to the local server using The central office comprises a telephone switch for providing telephone service to the subscriber and a concentrator for connecting a plurality of upstream repeaters to a number of office modems for providing data service to the subscriber. Communication systems use CAP or DMT line signals in a time sharing manner. The line signal is transmitted with various time framing. All subscriber lines can operate in one of three operating modes: asymmetric, semi-asymmetric, and symmetric. The office modem is connected to the office modem in the current transmission cycle, depending on the type of information source and the subscriber's home modem, the mode of operation of the subscriber line and the downstream / mode of operation. Change the upstream bit rate. |
