Abstract:
A unit and a system for protection switching of line cards in a telecommunication system are described. A protection unit is connectable between communication lines and a line interface unit. The protection unit can be interconnected with other protection units to form a protection switching system. One protection unit in the protection switching system is connectable to a stand-by line card. The protection switching system is configured so that when protection switching is needed, the line signal is re-directed between the communication line for a failed line card and the stand-by line card via electrical connection elements.
