Abstract: In an ATM cell assembling and disassembling method for a communications network having first and second communications nodes, HDLC data is transferred from a first terminal to the first communications node via a first transmission line, the HDLC data conforming to an HDLC format. It is started to assemble, in the first communications node, at least one cell from the HDLC data when data which is contained in the HDLC data and equal to one cell has been received. Then the above at least one cell is transferred from the first communications node to the second communications node. Disassembly is started, in the second communications node, of the above at least one cell to thereby generate original HDLC data when a fluctuation compensation time has elapsed after a first cell among the above-mentioned at least one cell is received by the second communications node. The fluctuation compensation time is based on a maximum fluctuation time of a route connecting the first and second communications nodes to each other as well as a bit rate of the first transmission line. Finally, the original HDLC data is transferred to a second terminal from the second communications node via a second transmission line.

Abstract: An ATM exchange system including a unit (1) for detecting management cells from among multiplexed input ATM cells, and a path creating unit (2) dedicated to the detected management cell. The path creating unit (2) is activated each time the management cell detecting unit (1) detects the management cell, and thus the management cell is transferred to the corresponding outgoing line without loss in the exchange, and can be transferred thereto before the user ATM cell.

Abstract: An information delivery system includes terminals receiving data via a satellite-communication system (6, 7), and a user centre (3) having a destination-conversion table (34) which lists a satellite-system receiver ID with respect to each ground-network address of the terminals, and, upon receiving a request for data delivery via an intra-network (2), obtains satellite-system receiver IDs from ground-network addresses indicated as destinations of the data delivery by referring to the destination-conversion table (34) so as to deliver requested data and a reception-control program to the destinations via the satellite-communication system (6,7). The terminals (1) use the reception-control program to check the data-reception conditions when receiving the requested data and the reception-control program, and send a request for a repeat of the data delivery to the user centre (3) via the intra-network (2) if the data-reception conditions are not satisfactory.

Abstract: In an ATM cell assembling and disassembling method for a communications network having first and second communications nodes (1, 21, #1, #n), HDLC data is transferred from a first terminal (28) to the first communications node via a first transmission line (26), the HDLC data conforming to an HDLC format. It is started to assemble, in the first communications node (#1), at least one cell from the HDLC data when data which is contained in the HDLC data and equal to one cell has been received. Then the above at least one cell is transferred from the first communications node to the second communications node (#n). Disassembly is started, in the second communications node, of the above at least one cell to thereby generate original HDLC data when a fluctuation compensation time has elapsed after a first cell among the above-mentioned at least one cell is received by the second communications node. The fluctuation compensation time is based on a maximum fluctuation time (Amx) of a route connecting the first and second communications nodes to each other as well as a bit rate of the first transmission line. Finally, the original HDLC data is transferred to a second terminal from the second communications node via a second transmission line (26).
