2.2 NODE INTERFACE
The SpaceWire Router has two external ports which enable the device to be used as a node interface. The equipment to be connected to the SpaceWire network is attached to one or both external ports. One or more SpaceWire ports are used to provide the connection into the SpaceWire network. Unused SpaceWire ports may be disabled and their outputs deactivated to save power. In this arrangement configuration of the routing tables and other parameters may be done by sending configuration packets from the local host via an external port or from a remote network manager via a SpaceWire port.

2.3 EMBEDDED ROUTER
The SpaceWire Router device can also be used to provide a node with an embedded router. In this case the external ports are used to provide the local connections to the node and the SpaceWire ports are used to make connections to other ports in the network. The difference between this configuration and that of section 2.2 is just a conceptual one with the Node interface configuration normally using fewer SpaceWire ports than the Embedded Router configuration.
