摘要： A performance management unit manages a primary interface and a standby or secondary interface to two channels of an optical communications network having APS capabilities. Each performance parameter is associated with three counters. First and second counters are linked to registers of the primary and the secondary ports, and the third counter is linked to the registers of the currently active port. When a protection switch occurs, the first and second counters are immediately read and reset. The third counter continues accumulating data, but becomes associated with the new active port. At the end of a read interval, the third counter correctly reflects the number of data received, regardless of switchovers between the primary and secondary channels.

摘要： 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.

摘要： Communication access apparatus includes a master shelf, including a master switching unit linked to communicate with a high-speed network, and a plurality of slave shelves. Each slave shelf includes ports that serve network subscribers, and further includes a slave switching unit, coupled to communicate with the master switching unit and to multiplex among the ports so as to provide the subscribers with access to the high-speed network. A management station is coupled to communicate with the master shelf and the plurality of slave shelves over a management network in which all of the slave shelves are on a single subnet.

摘要： Communication access apparatus includes a master shelf, including a master switching unit linked to communicate with a high-speed network, and a plurality of slave shelves arranged in a given system topology with respect to the master shelf. Each of the slave shelves includes ports configured to serve network subscribers, and further includes a slave switching unit, coupled to communicate with the master switching unit and to multiplex among the ports so as to provide the subscribers with access to the high-speed network, and to receive from the master shelf management messages that are addressed to an internal network-layer address that is determined uniquely for each of the slave shelves based on the topology. A management station is coupled to convey the management messages to the master shelf over a management network in which at least some of the slave shelves share a common external network-layer address by mapping the internal network-layer address of each of the shelves to a respective transport-layer address.
