required to be supported;
Category 3: Transmission characteristics specified up to
16MHz for 100 ohm balance cables.
Category 4: Transmission characteristics specified up to 20MHz
for 100 ohm balance cables.
Category 5e: Transmission characteristics specified up to 100MHz
for 100 ohm balance cables.
Category 6: Transmission characteristics specified up to 250MHz
for 100 ohm balance cables.
Category 7: Transmission characteristics specified up to 600MHz
for 100 ohm balance cables.
