An interface between a wireless node and a network node includes an encapsulator for temporarily converting data frames into Ethernet frames for the link between the two nodes and de-encapsulating the Ethernet frames before the data is processed at the network node.

Interface system for wireless node and network node

A data processor and storage system which comprises a data processor, a cache memory and a main memory is arranged so that the addressing of the main memory produces a multiplicity of spaced aliases, the multiplicity being greater than the set-associativity of the cache memory. The cache memory may be a multiple way set associative cache memory with the system including a round robin allocator for controlling the storing of successive data items in the different ways of the set associative cache. The cache may also be a direct mapped cache having single way set-associativity so that the round robin allocator is not required. The system may also include a direct memory access (DMA) device for copying data items into the memory. The memory may be a buffer memory which is divided into a plurality of packet buffers.

A socket connector has a single socket including fiber optic terminals,and wire terminals,and is adapted to receive alternatively in respectively inverted positions either a first plug connector for cooperation with the fiber optic terminals or a second plug connector for cooperation with the wire terminals, in each case without engagement with the terminals with which the plug should not cooperate. The connector includes respective latching slots,and,in opposite walls,and,for the respective plug connectors.
