Abstract
Architecture for a SONET network element. The architecture includes an interconnection system for a network element, including a line unit slot, a switch fabric slot, and service unit slots. The line unit slot is connected as a hub to the switch fabric slot and the service unit slots in a first star interconnection configuration. The switch fabric slot is connected as a hub to the line unit slot and the service unit slots in a second star interconnection configuration. The star interconnection configurations provide fault isolation between different units, and allow for replacement of failed units without interfering with the links of other units to the hub. A service unit is provided including a first backplane interface for connecting with an ATM star interconnect configuration within the network element, and a second backplane interface for connecting to an STM star interconnect configuration within the network element.
