WS-X6148A-GE-TX performance question

 Are the X6148A cards dedicated 1 gb/s uplink for each port ( shared 32 Gb/s
bus , as long as each port is it's own 1 gb/s still to the 32gb/s bus and
not shared with 7 other ports, so effectively just 125Mb/s per port then if
all used at full/even capacity) ?

I can't really find anything much on X6148A internal architecture online,
but it would seem that each port gets its own 1gb/s link to the
card/backplane, and that the bottleneck then is the 32gb/s backplane (which
is fine, as long as it's not 1 gb/s per each set of 8 ports!).
