Abstract
Multiplexing apparatus for providing access to a high-speed network over a plurality of subscriber lines. One or more line cards include ports to the subscriber lines, at least one of the line cards including a volatile memory for storing backup configuration parameters of the apparatus. A switching unit includes a non-volatile memory, adapted to store operating configuration parameters. A controller in the switching unit is operative to receive the backup configuration parameters stored in the volatile memory and to update the operating configuration parameters in the non-volatile memory responsive to the backup configuration parameters. The switching unit also includes a communication interface, over which it is coupled to communicate with the network in accordance with the operating configuration parameters so as to link the ports of the line cards to the network.
