Abstract: A method and device for communicating multiple communications networks from a single chassis is disclosed. In an exemplary embodiment, the communication device includes a processing unit, a network interface, a service interface, an endpoint interface, and a cluster interface. The processing unit controls various data flows in the communication device. The network interface communicates to at least one other communications network. The endpoint interface provides communication to local end devices and between local systems. While the service interface is designated to enhance service capabilities, the cluster interface is devised to expand system capacity. In this embodiment, the processing unit, the network interface, the service interface, the endpoint interface, and the cluster interface are assembled in one unit.
