Ethernet now available for existing backplanes
Existing CompactPCI and VME64x backplanes can use the fast switch technology (Gigabit Ethernet) with immediate effect: after a simple "mechanical upgrade" they fulfil the PICMG 2.16 and VITA 31.1 specifications respectively. 
This performance enhancement is made possible by a module developed by ELMA, which was registered as a utility model under the name Expand Overlay Kit. It opens up endless opportunities in new fields of application for conventional backplanes - in a simple and cost-effective manner.
The use of fast switch technology is no longer associated with costly redesigning procedures or the complete redevelopment of existing applications. In fact, the upgrade can be performed by simply connecting the existing backplane to an "expand ethernet switch backplane" via the "expand ethernet overlay module".
The module is plugged into the rear side of both backplanes, like a "bridge", which creates the necessary point-to-point connections in a Dual-Star topology (P3 on CPCI, P0 with VME64x). Two redundant fabric slots and six node slots can be used. This new module thus secures any investments that have already been made in CPCI and VME64x technology, says Dedicated Systems .
An additional advantage of the Expand Overlay Kit lies in the fact that experimental configurations for new developments and the testing of new standards can be conducted quickly and easily with existing backplanes.
Successful tests mean that decisions can be made as to whether a specific backplane should be designed for special applications or whether an existing backplane can be used with the Expand Overlay Kit - especially if only small quantities are required for the application.
Two Expand Overlay Kits are available for both of the CPCI and VME64x areas of application; each kit consists of an identical "expand ethernet overlay module" (161.6 x 44.0 mm, 2.2 mm thick - for the point-to-point connections) and a specific "expand ethernet switch backplane" (262.1 x 39.6 mm, 4.3 mm thick).
The connection characteristics are: 1,000 Mbs via 4 differential pairs between the fabric slots and each node slot (up to 2 Gb/s full-duplex), Ethernet protocol.
