ABSTRACT:
Apparatus for redundancy circuit protection includes a controller (20), a plurality of circuits (22) coupled to the controller (20), and a redundancy switch (50) coupled between the plurality of circuits (22) and a network. The redundancy switch (50) is adapted for connecting or disconnecting selected ones of the plurality of circuits (22) to or from the network. In addition, a predetermined number of spare circuits (52) with similar functionality as the plurality of circuits (22) are coupled to the high density bank control unit (20), so that the redundancy switch (50) may connect or disconnect selected ones of the predetermined number of spare circuits (52) to the network and establish a transmission path from the controller (20) through the selected spare circuits (52) to the network.
