Abstract:
A communication system for transmitting cell/packet-based signals comprising: a time division-based point-to-multipoint network and at least two local area networks that are communicatively connected by said time division-based point-to-multipoint network, each of said local area networks comprising:(a) a switch for providing information formatted within cell/packets, (b) an interface for connecting to said switch, said interface comprising a time stamp processing unit and a frame counter unit; (c) first means for combining an output from said time stamp processing unit and an output from said frame count unit with a cell/packet to form a time marked cell/packet, respectively; (d) second means for assembling a plurality of said time marked cell/packets into a time division frame; (e) a modem for connecting said time division frame to a transmitter for transmitting time division bursts; (f) a modem for receiving time division bursts and detecting a time division frame; (g) third means for disassembling a plurality of time marked cells or packets in said detected time division frame; and (h) fourth means for detecting cell/packets on the basis of said respective time marked cell/packets.
