1. A termination device for connection to a group of TDM (time division multiplexed) links comprising:

  • an interface circuit for receiving an incoming cell stream forming one or more virtual channels, a buffer memory for storing incoming cells at memory locations identified by pointers;

    a pointer queue for each virtual channel, said pointer queue indicating the memory locations of queued cells in each channel;

    a control unit for interrogating the pointer queue and assigning the next incoming cell to the next free memory location for the associated channel, a scheduler selectively operable to sequentially assign cells from each queue in said buffer memory either to individual links or to a group of links forming an inverse multiplexed group; and

    a per link output circuit for placing cells from said memory locations on said links to form outgoing virtual channels.
