Gigabit Ethernet on port 0 and 1 are connected to T5002 cross point switches. This allow to route
these signals to the front SFP modules, onboard LAN, to the backplane or between the two AMC.
Moreover, it is possible to use different signaling than gigabit ethernet 1000Base-BX since cross
point switches are not aware of data encoding. Any differential signals compliant with AMC.0 and
ATCA 3.0 specification up to 6.5Gb/s can be used, provided a compatible endpoint exist.
The SATA interface on port 2 allow to use SATA AMC storage mezzanine. Note however that the
6300ESB doesn't support hot swap on SATA. It is correct electrically to hot swap a SATA AMC but it
may cause driver problem in different operating system.
The telco clock signal allows the AT8001 to provide clock to the AMC on CLK1 and CLK2. It also allow
an AMC to retrieve a clock an to provide it to the system through CLK2. For possible clock frequency
and connection with the backplane, refer to section TBD.
