Summary:The specification discloses methods and apparatus for selecting the better of two or more copies of a cell in a cell-oriented redundant switching system (107, 108) connected to an external communication network. In the preferred embodiment, the best cell copy selection (109) aligns redundantly transmitted cell streams before selecting cells for insertion in the data stream. Because the streams are aligned before the selection is made, the best cell copy selector compares each cell at the same instant in time, rather than basing its selection on past events.
