CELL SEQUENCE STORAGE TYPE SELF-ROUTING CHANNEL DEVICE

摘要

PURPOSE:To prevent a cell after channel path revision from getting ahead of a cell before channel path revision by giving information passing through the new path to a channel after the sending of the last cell before the switching to an outgoing highway at the channel path switching. CONSTITUTION:In the case of revising a channel path during talking because of the occurrence of congestion or the like in a self-routing channel 1. prior to the change is channel path information by a channel path information change means 3, a last cell information addition means 4 adds last cell information to be switched according to a path based on the channel path information before the change by the change means 3. Then the change means 3 changes the channel path information and all cells are stored in a temporary storage means 5 via a switch 6 according to the path. Then the cells in the storage means 5 are sent sequentially by the operation of a last cell information detection means 9-i and a cell sequence storage control means 8.
