connected using the same bus. Accommodate in the range where the total of each
line speed does not exceed 600M bits/s. NIF1 is not restricted by a bus and each NIF
can be accommodated to the maximum. The shared-bus structure of GR2000-2S is
shown in Figure 4-3. NIF0 and NIF1 in the figure indicate the slot of NIF.
See the accommodation conditions in Table 4-10 when using 100BASE-TX. See the
accommodation conditions in Table 4-11 when using 100BASE-FX.
An implementation example is given below. (For 10BASE-T/100BASE-TX and
100BASE-FX, calculate in full duplex.)
