Abstract
Two identical and interconnected switch matrices are used wherein one is 'on-line' and the other is 'off-line'. If an individual module in the on-line switch fails, an identical module in the standby matrix is switched in to carry traffic. The failed module can then be replaced with an operable unit. The feature of modularity not only greatly enhances the performance of the switch matrix but also provides for quick restoration of the switching apparatus to a preferred configuration of operability.
