The PSB 2.16 backplane is based on the PICMG backplane. The VITA 31.1 has simply been enhanced with a Gigabit Ethernet Link.
This leads to a PICMG 2.16 Gigabit Ethernet Switch (Fabric) which connects the links (nodes) with one another. This can also be connected to the front panel with an RJ45 connector, if needed.
