| 1. A service unit for a network element, comprising:
a first backplane interface to said network element, said first backplane interface conveying payload data using a first communication
protocol,
wherein said first backplane interface is communicably coupled to a first star interconnect configuration within said network
element, said first star interconnect configuration including a line unit slot; and
a second backplane interface to said network element, said second backplane interface conveying payload data using a second
communication protocol,
wherein said second backplane interface is communicably coupled to a second star interconnect configuration within said network
element, said second star interconnect configuration including a switch fabric slot,
wherein said line unit slot is communicably coupled as a first hub to said switch fabric slot and said first backplane interface
to form the first star interconnection configuration, and
wherein said switch fabric slot is communicably coupled as a second hub to said line unit slot and said second backplane interface
to form the second star interconnection configuration.
